Linux Application Debugging on Windows Host

I want to debug Linux applications using replay debugging with this setup:
Windows Host (Windows 64 bit), VMWare Workstation 7.0
Linux Guest 1 (32bit) for development and running gdb
Linux Guest 2 (32bit) running the application which should be debugged
For simpliciy both guests will use the same Linux distribution to ensure that all libraries are the same.
The idea is to start the vmware-gdb-proxy on the Windows host and connect form guest 1 to the proxy to debug on guest 2.
But there seems to be no vmware-gdb-proxy available for Windows - so my questions
is there a vmware-gdb-proxy avaible (or is it planned to make one available) ?
have I missed something? is there another way to do replay debugging Linux applications on Windows hostt?
Thanks,
Christian

Of course you can.

Debugging Linux applications on Microblaze

Hello,
could someone please answer some questions who is debugging Linux applications on Microblaze.
I have to prepare an environment to debug applications running on Microblaze Linux 2.6.38. Everywhere, I can find hints how to do it with ARM on Zynq, but this is only a Spartan-6. I might change the Linuxversion but not the hardware.
First, I compiled the kernel 2.6.38 (PLB, big endian) with initramfs_minimal.cpio.gz, then I compiled it with initramfs_complete.cpio.gz. In both cases, the Linux Kernel is running on Microblaze and I can access the filesystem with a serial link and with LAN using telnet.
To debug applications, I tried to run with Windows 7 (64-bit) the Xilinx SDK (Eclipse) included in ISE/XPS 14.7. For Linux applications running on Microblaze, I tried to use the GDB-Debugger in SDK. I think I have to start a GDBserver first and then start SDK to connect to it.
I could not find the GDBserver in the above mentioned filesystems. So, I downloaded the GDB sources for GDB 7.7 and did two configurations. One for the host (first VirtualBox with Ubuntu-Linux-32bit, later Windows 7) and one for the target (microblaze running on spartan-6).
to create the GDBclient for the PC:
configure --prefix=/opt/gdb/mb-linux/cross --target=microblaze-unknown-linux-gnu
The following commands 'make' and 'make install' are running without errors.
to create GDBserver for the FPGA:
configure --prefix=/opt/gdb/mb-linux/native --host=microblaze-unknown-linux-gnu
There is an error with the following command 'make'.
error: Gdb does not support native target microblaze-unknown-linux-gnu
I have really tried a lot, looked at many pages, e.g.:
http://www.wiki.xilinx.com/
Xilinx Wiki - Getting started
Xilinx Wiki - MicroBlaze
Xilinx Wiki - Create Linux Application
Xilinx Wiki -Debug Application
Many links were broken and if accessible, debugging Linux on Zynq or debugging a standalone application on microblaze was described.
It would be very helpful if someone who actually did debug Linux applications on microblaze with or without SDK could describe a little bit how it works.
Is GDB included in either of these filesystems and I did not see it ?
Do I need to create GDBserver ?
What is wrong with my settings to create GDBserver ?
Is there a totally different way to debug ?
Thanks in advance for your help,
Michael

Hello Achutha,
thank you for your reply.
I already knew those two links but I took a close look at them again.
The second link helps to run a Linux kernel on Microblaze. It ends when it's getting interresting for me. It does not describe anything about developing a Linux application.
The first link is using Zynq. Most of the steps can be done with Microblaze as well. When I start debugging, it changes to the debug perspektive and after some seconds I see the message
Hello_Linux_Debug(SDK Linux TCF Agent: Disconnected): Connection refused: connect
SDK.log in the SDK workspace shows:
15:20:34.399 ERROR - Unexpected error while parsing XMD response ?: com.google.gson.JsonSyntaxException: com.google.gson.stream.MalformedJsonException: invalid number or unquoted string near
I tried the following options but nothing helped:
Kernel with initramfs_minimal.cpio.gz and with initramfs_complete.cpio.gz.
Changed the access rights of /tmp (I used it for 'Remote File Path')
In the video for Zynq, it is said:
by default, there is a TCF agent running
I guess, the TCF agent can be seen on Zynq if you list all processes running.
What is the name of the TCF agent?
I guess this one is missing on my Microblaze.
Any other suggestions?
Kind regards,
Michael

Remote debugging from Windows to Linux

Is there a full description of every step needed to do remote cross-platform C++ debugging? I'm using the Indigo version of Eclipse CDT on Windows and would like to debug an application on a remote Linux machine.
On Windows, I do not have the ability to install a compiler or cygwin, but I do have plink and ssh on Windows. I am able to access the remote machine via RSE SFTP (a la stackoverflow.com/questions/4216822/work-on-a-remote-project-with-eclipse-via-ssh). I do have VNC but I find that the Eclipse IDE is very unresponsive under that setup, hence the desire to develop and debug from a native Windows app.
This FAQ is the most complete (wiki.eclipse.org/CDT/User/FAQ#How_do_I_debug_a_remote_application.3F), but doesn't discuss how to deal with Windows using backslash paths and having a different filesystem root compared to Linux and its forward slashes.
I am able to get a remote connection by playing around with the suggestions here (www.eclipse.org/forums/index.php?S=5e54b35462bb80f79ebb9fbbaf93a288&t=msg&th=173880), resulting in console output that looks like:
Last login: Fri Apr 6 20:19:09 2012 from foo.bar.com
echo $PWD'>'
/usr/bin/gdbserver :12345 /linux/path/to/my/binary args_to_my_binary;exit
but it fails with "Error while launching command: gdb --version"
The old FAQ is very incomplete and seems out of date: wiki.eclipse.org/TM_and_RSE_FAQ#How_can_I_do_Remote_Debugging_with_CDT.3F
This suggests it's possible but does not have sufficient details on how to set the myriad configuration options in Eclipse: stackoverflow.com/questions/6044138/remote-debugging-in-eclipse-cdt
I suspect many people would benefit if there was a clear set of instructions in one place on how to make this happen.
--Gerald Dalley

OK. I just spent the last two days figuring this out, so here are step-by-step instructions that hopefully will help others (This list is unusually anal by the standards of this group, but really simple concrete instructions would have helped me).
on the target linux box, make sure you have gdbserver. If you don't, get the gdb sources. Note: Making gdb does not build gdbserver. Instead, you have to go into the gdbserver directory and configure/make there.
Run gdb on the linux box. In the startup banner, it will say what its target is. This will be something like x86_64-unknown-linux-gnu or i686-pc-linux-gnu. Remember this for later.
Install MinGW on your Windows box (I had trouble building gdb on cygwin, so I recommend MinGW).
Download expat from http://sourceforge.net/projects/expat/files/expat/2.1.0/.Note: Do not download the Windows expat installer. Download the sources instead.
In the expat directory. "./configure --enable-shared", make, make install.
Download the gdb sources
../gdb-7.4/configure --with-expat --target=x86_64-unknown-linux-gnu --host=i686-pc-mingw32
make, make install
Time to test. On your linux box, create and compile hello.cpp to hello.
On your linux box, gdbserver :4444 hello
Note:If you are on a corporate network, non-standard ports may be blocked. Set up an ssh tunnel if necessary.
Copy hello.cpp and hello to your Windows machine
From the MinGW prompt, run "x86_64-unknown-linux-gnu-gdb ./Hello" Note: Substitute the name of the gdb you built as appropriate based on the target platform you got in step 2.
In gdb, load the executable with "file hello"
target remote localhost:4444 Note: This assumes that you have an ssh tunnel on localhost. Modify appropriately.
Verify that gdb commands like break, cont, and run work here.
Now we want to run it from outside of MinGW. In Control Panel/System/Advanced/Environment Variables add something like E:\MinGW\bin to the path. This is necessary for the loader to find libiconv_2.dll, etc. Now verify that you can do the preceding step from an ordinary Windows command prompt.
Launch Eclipse (finally!). New debug configuration C/C++ attach to process.
In Main, give path to the copy of the Linux executable on the Windows system.
In Debugger tab, set Debugger dropdown to gdbserver. Set "GDB debugger" to something like "E:\MinGW\msys\1.0\local\bin\x86_64-unknown-linux-gnu-gdb.exe" based on where your gdb is. For Connection, choose TCP and fill in the hostname and port number you've been using from gdb in the previous steps.
Make sure gdbserver is running (it often quits when the program ends) and launch the debug configuration
In the gdb console, enter "file hello," "break main," and cont or run (sometimes it wants one. Sometimes the other) and voila, you should be there.
Let me know if this works, and I'll post it somewhere better.
Good luck,
Mike

CI/DB under Linux and AS under Windows - Possible?

Hello all,
I have an ECC6 running on Linux/Oracle.
For some interface reason I need my production to communicate to a MS SQL Server Database - we found out that the best solution was to install a new Application Server under Windows.
Is it feasable? If yes what are the constraints or does anyone can give me the procedure.
Thanks for your time and your help.
Regards,
Mel

hi melchior,
Why not installing MS SQL on Windows Server and connect it to your SAP system without have to install SAP system on this Windows host ?
It's possible to install SAP system on heterogent system. For UNIX/Linux and Windows system, you need to manage SAMBA service.

Read_image_file command does works on Linux application server

Hello!
I have a form with a new_form_instance Trigger I wrote the read_image_file trigger to read a GIF file in an image item.It works fine on windows XP(development machine).I copied the GIF file to the same location where my fmx files are there in Linux application server.I copied and compilied my fmb file in linux application server.No compilation error is there.But when I run form from Linux the form hangs and my read_image_file command is at new form instance Trigger.I have checked the case sensitivity of the file and the permission etc in Linux.In windows Development machine the form runs successfully.What could be the problem.Please help.......
Jayashree

For me, attempting the following:
  READ_IMAGE_FILE('bullet_ball_glass_blue.gif', 'GIF', 'IMAGE7');
gives this error:
  FRM-47109: Cannot locate image file bullet_ball_glass_blue.gif
Changing my command to:
  READ_IMAGE_FILE('bullet_ball_glass_blue.gif', 'URL', 'IMAGE7');
loads the image successfully.
If you truly are not getting an error message (mine appears in the status bar), then perhaps the file is being found, but the image format is not recognized or otherwise incompatible. Test this by loading one of the the images that load successfully into your iconic buttons. If that image loads successfully into your image item, fix the problem GIF image. (Recreate or open & resave with a graphics program, etc.)
If this does not appear to be the problem, the only things I can think of are for you to confirm that, in formsweb.cfg:
  1. The archive_jini entry includes your image JAR
  2. If imageBase=DocumentBase, change to imageBase=codebase
The second change may temporarily break your iconic buttons. This can be fixed by updating the buttons' Iconic Filename properties specifying only relative paths found within the JAR. Since my image is stored in the root of my JAR, no path need be specified. Had I placed my image in a subdirectory within my JAR, named images, my call would have to be changed to the following:
  READ_IMAGE_FILE('images/bullet_ball_glass_blue.gif', 'URL', 'IMAGE7');
I'm not sure whether any of these suggestions will help, but since I had no problems, I suspect it's simply a matter of differing configurations. The two items that I listed are the only two likely differences I could think of.

Unix or Linux application compatibility with X11 terminal/Mac OS X

I am an engineer and thinking about upgrading to a MacBook Pro. Most if not all of the applications that I use with respect to my work can be acquired in Linux or Unix flavors. I went to the local Apple store and requested that a "genius" install this software on a MacBook to take it out for a test drive. The "genius" was not able to install the application. Do I assume that the application cannot be installed, or that the "genius" did not know his stuff? I would really like to get the MacBook but want to be sure that my Unix and Linux apps will run on it. What is the compatibility issue here? Will any Linux or Unix app run on the Mac? Will the applications run only as command line or will a GUI be available? I need to hear from someone that knows the OS X.
MacBook Pro Mac OS X (10.4.8) thinking about purchase
Mac OS X (10.4.8)

I've worked with some pretty smart people, including Nobel laureates, and there are very few people I would say qualify as geniuses. It is unlikely they all work retail at Apple stores.
Anyway, what you are requesting is fairly standard. I made a web page to help you get going.
Briefly, you can run almost anything from Linux, but you have to compile it. There are free downloads for the compilers in Xcode, and X11 comes as a non-default install with the operating system (and the computer you would be buying). You can then either do it all yourself or use a package management system such as Fink or DarwinPorts (MacPorts?) in a similar way to how this is done on Linux.
There are some kernel-interacting linux applications that you might not be able to get to work, but I'd say well over 99% of what you would want will work fine. I use OS X as my primary scientific computing environment.
If you need Linux, you can install that too, and even run it in Parallels (a 3rd-party virtualization software that allows you to install windows, linux, or any other i386 OS).

Linux application loader - will it work?

Hello.
There already is a tool named "lxrun" which emulates a Linux kernel (system calls) on Solaris. Unfortunately this tool requires a full set of shared libraries and many other files.
I noticed that most C functions (such as fopen, strcmp, ...) are the same in Linux and in Solaris, the same calling convention is used and applications nearly never do system calls directly.
Therefore I plan to write some kind of replacement for ld.so.1 that will load Solaris' .so files, Linux .so files special wrapper .so files and a Linux application into one process. This is similar to "Wine" for Windows applications.
My idea is that the Linux application will then be runtime-linked for example against Solaris' libc.so.1 instead of Linux' libc.so.6 and so run under Solaris. The wrapper .so files handle all commands not present in Solaris and all commands that are different in Solaris and Linux.
Question to the people that are really familiar with both systems:
Would such a program work???
Martin

Debugging C# Windows Service

I am trying to debug a C# Windows Service in Visual Studio 2005 with ODT as it accessing SP's on an Oracle 9.2 database. I would like to find out if it is possible to debug the Windows service as I have to install it, have it running, then attach to process.
thanks

Yes it will work just fine. Just use "External Application Debugging" and 2 instances of VS. Before the Oracle connection is first made by the service, make sure the ORA_DEBUG_JDWP environment variable is in the environment of the service. Use one instance of VS for debugging the service code, and a separate VS instance for PLSQL.
The steps:
1) Configure PL/SQL Debugging for first use. (See the doc/FAQ if you don't know how)
2) Open 2 instances of VS
3) In the one you use to debug PL/SQL, enable External Application Debugging and choose the port and set breakpoints
4) In the one use to debug the Windows Service, attach before the Oracle connection is made and set the ORA_DEBUG_JDWP environment variable in the environment for the service. When this service connects to Oracle, you should see the other instance of VS note this in it's output window.. If that is not possible, just make sure that you set up the service to include this env variable and restart it.
5) In the Windows Service, set a breakpoint before and after the stored procedure you are interested in.
6) Run to the break point and when you call the SP, the other instance of VS should wake up at the breakpoint.

I have one paid mobileme account, few days ago I have done transition to iCloud and all my iDisk, contact... gone. Today I tried login to iCloud application on my windows pc (64bit) but I can not, it said "this apple id is valid but is not iCloud account". I can login on website icloud.com but can not login into iCloud application installed on pc. What's wrong?
I have tried another free apple ID and logged on. That's funny when I can login with free account and can not login with paid mobileme account!!!!!!

By the way - the only reason I downloaded iCloud is because Apple deleted the backup option from iTunes. Since iCloud doesn't work, I guess we have no way to protect our iTunes music collection. Absolutely stupid.

Office 2013: Windows host process (Rundll32) has stopped working

Hi,
I have problems with adding additional e-mail address to my Outlook. When I open the Mail Control Panel Item, go to my Exchange Profile and add a new e-mail address I get a popup indicating that the Windows host process (Rundll32) has stopped working.
The only way of adding extra e-mail addresses is to remove my entire Outlook Profile. In the initial wizard I can add all Exchange mailboxes that I need (I have 3). After I've configured my Outlook profile I always receive the Rundll32 error. When I try
to create a second Outlook profile I still get the same error.
I've tried the following:
- Repair OST file
- Repair Office -> Control Panel and Online Repair
- Reinstall Office
- Reinstall my entire PC
It doesn't matter which e-mail address I add in the initial Outlook configuration wizard. I always receive the error when I try to add a new mailbox, even when I add a mailbox that does not exist (e.g. [email protected]).
Even after reinstalling my PC I still get the same error. I'm using Windows 8.1 (x64) and Office 2013 (32-bit) on a Lenovo W540. None of my colleagues have this issue. It's a domain joined PC and we are not using Roaming Profiles.
For troubleshooting I also created a local account on my laptop but I get the same issues with this account.

Hi,
I'm also using Office 2013 32-bit and Windows 8.1 64-bit on my computer but doesn't get this issue. As you mentioned you reinstalled your PC, the first thing I suggest is to make sure your Windows and Office have been up to date.
The second thing is to make sure you are using the system with an administrator account, this ensures you the enough permission.
There is a possibility that some 3rd-party programs are interfering with "Mail", we can try to perform a clean boot to determine whether background programs are interfering with this:
1.Swipe in from the right edge of the screen, and then tap Search. Or, if you are using a mouse, point to the lower-right corner of the screen, and then click
Search.
2.Type msconfig in the search box, and then tap or click
msconfig.
3.On the Services tab of the System Configuration
dialog box, tap or click to select the Hide all Microsoft services
check box, and then tap or click Disable all.
4.On the Startup tab of the System Configuration
dialog box, tap or click Open Task Manager.
5.On the Startup tab in Task Manager, for each startup item, select the item and then click
Disable.
6.Close Task Manager.
7.On the Startup tab of the System Configuration
dialog box, tap or click OK, and then restart the computer.
If in clean boot the issue doesn't exist, the issue was probably caused by the 3rd-party programs. For further information to troubleshoot, you can refer to this kb below:

Application Runs Under Windows 8.1 But Not Under Windows XP (I Know XP Is Deprecated)

The problem is with the obtuse error message put out by Windows's program loader. It reads, in part, "..is not a valid Win32 application." The application runs everywhere except on Windows XP. Looking for root cause of the problem. It's a very
simple application. Only a few lines of code.
C:\Packaged-Software\32-BIT\Reboot.exe is not a valid Win32 application.
Proposed nature of the problem:
1. The file was downloaded from a website but the download was incomplete.
2. The full file system filename path contains bad characters such blank space.
3. Visual Studio constructed an application that won't run anywhere much less on XP.
4. The supporting libraries are not properly installed (e.g. .NET Framework4, and VCREDIST).
Retorts:
1. The file wasn't downloaded from a website and is intact.
2. The filename path doesn't contain any spaces.
3. The application runs under Windows 8.1. Also on Windows 7.
4. The supporting libraries are properly installed.
So, what's the problem? One surely will not discover the root cause from "not a valid application."
Body must be 4 to 60000 characters long. I had put the code here. It isn't 60000 character long. But it validated as if there are more than 60000 characters. Sorry for the incomplete submission due to website construction error.

Hi F7H2fw,
How did you develop the application ?
Here is a similar symptom and this may explain the issue somehow:
Setup.exe is not a valid Win32 application
http://blogs.msdn.com/b/vsnetsetup/archive/2012/10/16/setup-exe-is-not-a-valid-win32-application.aspx
I suspect there is a compatibility issue here .
Considering this is more likely a developing issue .It is recommended to ask for help from our MSDN Forum .They are more familiar with the developing issue .If it is possible ,please attach the code in that thread .Thanks for your understanding and cooperation.

Installing old application to OS Windows 7 64-bit

I have OS Windows 7 64-bit on computer and I am trying to download software from Amervets that is a Military Database. The webmaster from that site stated:
The War Library military-access software works on ALL versions of Windows from Win 1.0 to the present, and all UnRestricted bit formats from 8-bit to 1024-bit (current). It sounds like you were lured into purchasing
a Restricted-mode, 64-bit-only version of Windows. This is common in Hewlett-Packard, Dell, Sony (Toshiba), Samsung (Acer), Compaq and Gateway which primarily sells service assistance and upgrades.
2/2. It was not Microsoft's intent that the PC manufacturers named above remove or disable a primary Windows operating feature solely to resell that function as an upgrade when the user would inevitably realize some
software programs won't run.
Dell tells me my OS is not restricted and the problem lies with the software program being written for a 16-bit OS and 64-bit is not compatible. The Web master offered a work around to install a Virtual Box and down load what it called a unrestricted
Windows program. But I am not too tech savvy and if the future lies in the 64-bit world . . .I would hope the software would soon be updated accordingly.
I guess my question to the pros at Microsoft who is telling me the truth??? and is there any hope of me getting this database on my computer so I can continue my research.
Thanks for any help you can give

Hi,
Actually, we cannot install 16bit application on 64bit Windows 7.
In order to run a 16-bit program or a 32-bit program that uses 16-bit processes or 16-bit components, you must install the program on a 32-bit version of Windows. In order to run such a program, you can install a 32-bit version of Windows in a dual-boot
configuration with the 64-bit version of Windows. Then, you can restart your computer to the 32-bit version of Windows and install the 16-bit program or 32-bit program that uses 16-bit processes or 16-bit components.
You can refer to this article for details.
64-bit versions of Windows do not support 16-bit components, 16-bit processes, or 16-bit applications
