CC for Linux with Sun Studio 12 gets Signal 11 parsing gtk.h

I just install SunStudio 12 on a Fedora 7 Linux box, and it appears it can not compile
even the simplest gtk application written in C++.
/opt/sun/sunstudio12/bin/CC -c -g -I/usr/include/gtk-1.2 -I/usr/include/glib-1.2 -I/usr/lib/glib/include tstgtk.cc
>> Signal 11:
while processing /usr/include/gtk-1.2/gtk/gtk.h at line 1.
tstgtk.cc only contains the one line
#include <gtk/gtk.h>
The same command works if I replace the CC with lowercase suncc or with g++.
/opt/sun/sunstudio12/bin/sunCC -V
sunCC: Sun C++ 5.9 Linux_i386 2007/05/03

This is probably different problem since the one mentioned above is in compiler's front end, which shouldn't depend on target architecture option, which from what I know affects back end only.
Can you post source code of hello.cc here so that we can reproduce it?
Thanks!

Problems with sun studio 12 in suse linux 11

Hi.
I installed Sun Studio 12 suse linux with no problems. However, the debugging modules (DBX) are not working any more. When I started Sun Studio, it gave a message about modules that could not be loaded in tha moment. I did not pay attention. But I noticed that all debugging options were disabled.
Using the module manager, I saw the DBX module was not checked, and I could not change it. I was marked with a red X. So I thought to reinstall the application. However, the uninstall utility doesn't work either.
According with the documentation, running ./uninstaller does it, but I get the following error message instead
Exception in thread "main" java.lang.NoClassDefFoundError: uninstall_Sun_Studio_12/class
Caused by: java.lang.ClassNotFoundException: uninstall_Sun_Studio_12.class

I tried to uninstall manually, and then execute installer, by using first the software manager in linux and deleting the producregistry file manually. It worked because I executed the installer. However, in Sun Studio IDE, debugging options are still not available despite I "reinstalled" the application. I checked the log files and they say the file uninstall_Sun_Studio_12.class could not be written.
So my questions are:
1. Is there any other way to repair Sun Studio? What could be the possible for this module to stop working?
2. Does anyone have an idea of why the installer cannot write the uninstaller class?
I found that perhaps problems regarding Java / Netbeans versions could be the problem, but the ones I have installed are those packages that were installed along with Sun Studio, and both are valid.
Thank you very much.

Perhaps you can simply delete the Sun Studio 12 installation tree, because it will not work on SUSE Linux 11.
This OS is not supported, so any problems you see with SS12 on SUSE 11 will not be fixed.
But we have a newer version, that should work better.
You can try to download and install Sun Studio Express 2008/11 (extract pre-installed image from tar.bz2 file).
Here is a pointer to the web page:
http://developers.sun.com/sunstudio/downloads/express
All you need is to provide a email address, and press "Download Now" button.
You will see a page, that gives you 2 options to download Sun Studio Express 2008/11.
Use "Option 2": Download Tarfile Installer

Possibly the actual CC (or cc) command lines are not correct. The proper way to say not to link libCstd is the command-line option -library=no%Cstd. Then you don't need to add the default system libraries like -lc to the command line.
Can you show the actual CC command lines that are generated by the makefile? They should be in the compilation log. I'd also like to see the command line(s) used to create dynamic libraries, if any, and the final executable.

How to generate gdb compatible .o for CMT using Sun Studio C compiler?

Hello,
we've been working on a joint project for telco bearer plane applications on CMT.
We started the project using gcc for Sparc and we switched to Sun Studio compiler when we hit some bugs in gcc (optimized mode was not completely stable). The switch took a few weeks due to syntax differences and toolchain option changes.
With Sun Studio we got a double digit percent performance improvement, so Sun Studio proved more stable and faster than gcc.
To debug programs we require gdb, because the Telco customers are more familiar with it. The problem is that Sun Studio generates object files which are not compatible with gdb.
Our main requirement is to be able to generate gdb compatible object files using Sun Studio compiler.
We checked this link:
http://cooltools.sunsource.net/gcc/ReleaseNotes.html
but this seems to be a variant of gcc. At this point we cannot switch compiler because of the performance and stability issues mentioned above and because it will take a few weeks to months to switch.
We have two questions:
1) Is there a way to generate gdb compatible object files using Sun Studio 11?
2) If not, is this funcionality going to be available in a future release of Sun Studio and what is the time frame?
Thanks for your help.

The undefined symbol is in the C++ runtime support library that is part of Solaris. Probably you have an out-fo-date version of the libraries.
You can get current patches from the Sun Studio patch page:
http://developers.sun.com/prodtech/cc/downloads/patches/index.html
From the page for your version of WorkShop or Sun Studio, select the C++ Runtime Library patch for the version of Solaris that your are running. While you are at it, you can get the current compiler patches as well.
If patching the runtime libraries does not fix the problem, let me know, and also show the exact command lines that you use for compiling and linking the program.

Trouble viewing disassembly with Sun Studio 11

I was wondering how someone can bring up a window with a program�s disassembly when debugging a C program with Sun Studio 11. (SPARC). I would like to be able to set breakpoints at specific assembly instructions using Sun Studios�s GUI interface rather than using typed commands with DBX. I would also like to know how to get a window that shows the current value of the registers. Any help would be greatly appreciated.
Chris

Oops, it appears that you can't set breakpoints
through Disassembler window, it just shows the code
and current position within the code, that's all.It
gives you better view of context than dbx's 'dis' or
'list -i' commands, though.Actually you can set breakpoints through Disassembler window:
- select an address, click right mouse button to open context menu
- choose "Set Breakpoint"
If you need this feature, please file an RFE (Request
For Enhancement) through bugs.sun.comThe Disassembler window has been significantly improved between
EA1 and FCS. Now users can set and delete breakpoints using the
same way as they do in source file - click on the left gray area (toggle
breakpoints). Also Disassembler window has "Step Into", "Step Over",
"Step Out" and "Run To Cursor" buttons.

Is it possible to run sun studio 12 ide with sun studio 8 compiler?

Hi, i am in the process of evaluating sun studio 12. Our company cannot move to sun studio 12 compiler collection right now as it is a huge code base and it will take us few months even before we start using sun studio 12 compiler in our development environment. Is it possible to use sun studio 12 ide with sun studio 8 compiler collection(CC, dbx etc)? Your feedback is appreciated. thank you.

There are two parts to the answer.
1) whether you can
To choose a compiler set follow Tools->Options->C/C++
and in the BuildTools tab you'll see how it picks up
compilers from your PATH.
This dialog doesn't govern choice of dbx, which will always
come from the installation. However you can alter which dbx
is used by presetting the environment variable SPRO_DBX_PATH
to teh full pathname of a dbx of your choice.
2) whether you should
The IDE should work reasonably well with older compilers. They
are not that tightly bound.
The IDE will not work well enough with an older dbx, especially as
old as studio 8. However, while not officially supported or tested
the SS12 dbx should be reasonably bwd compatible with code
generated from older compilers.
So my recommendation is: don't use SPRO_DBX_PATH and
give the old compilers a try.

External Hard Drive for PowerMac G5 for use with FCP Studio

Hello,
I'd greatly appreciate any recommendation for an external hard drive for a PowerMac G5 for use with FCP Studio.
Thanks.
-graziemile

We see alot of Lacie issues here and elsewhere.
Drives fail... period. I believe you hear more about Lacie drives failing because they sell a ton more of them than many other suppliers. I've got 8 of em sitting right here on the desk and two more at the second station. I've lost one since I started using them years ago (and it had problems right out of the box) and I use them pretty heavy.
I understand that they use several different brands of drives in their enclosures, but from my experience they must have pretty good QC standards for what they package.
The guy said the G Techs were a little overkill for his needs. Lacie doesn't pay me. But if someone asks "how are Lacies?" I'll tell them they've been great for me and many others I know, especially if your requirements are capturing DV.
In five years, I ain't heard anybody say anything about it.
As for FCP. I love it! In 20 years of business, it's probably the purchase that's given me the most bang for my buck. But if you haven't heard people knock it, you've never met an Avid zelot, bruhhhhh, just the thought gives me shivers.
The drives X mentioned are designed for video work.
What Studio said, well he gives out some of the best advice on this board
(and maybe the most! ) and my reply to his post... that's why I used the little smiley face. No offence intended X.
I only meant to say that, in a world where software like FCP can do what it does at the price it does it, and drives like Lacie and G Tech can give you the storage they do for the price they do, the line between consumer and professional products is easily blurred.

-nodisplay bug with Sun Studio 10 for Linux installer

I'm currently trying to install a trial Sun Studio 10 for Linux on a Fedora Core 3 box. I want the installer to run via the command line, so I use "./installer -nodisplay", but I get the following error message:

libXp is part of the X window system, but I've specified -nodisplay. A non-graphics option shouldn't be trying to load graphics libraries - looks like a bug. Anyway, as I don't have version 6 of that lib on my system, I'm stalled on this. Any suggestions?

OK, I tried latest version of CC from Sun Studio 12 update 1 and can say that
- the error about constructor not being accessible is Sun C++ compiler "feature" (only called feature because it existed for so long) that allows binding of rvalues to non-const references; this "feature" will probably be turned off in the next release. It can't be changed in a patch because client's code might rely on it.
- the other errors are also not Boost-specific: the result of incompatibility of Linux headers and Sun C++ compiler; more thorough investigation is due, but in the past we had several problems like this. This particular can be solved by adding
-D_GNU_SOURCE to compile line.

Need help building boost_1_37_0 on Solaris 10 U6 with Sun Studio 12

Hi,
Ok, please bear with me here. I've tried many different sets of instructions, and haven't had success with any of them (including the ones at http://blogs.sun.com/sga/category/Boost).
Operating System: Solaris 10 x86 U6
Compiler: Sun Studio 12 (SUNCC version 5.9)
Boost version: 1.37.0
The ONLY part of boost that I need is regex. I've never built external libraries before and building boost on Solaris seems a rather daunting task. So, could someone please explain, as clearly as possible, how do I build the boost::regex library using SUNCC?
I know this is a very broad topic, but since I haven't had any luck with any existing instructions that google turns up, alas I am here.
Thanks in advance if someone can help me,
~Slow
Note: I don't need any special options, any special, non-standard install paths, nothing. Just a straight, stock, boost install.
Edited by: SlowToady on Nov 10, 2008 2:18 PM

First, be sure you have the current patches for Sun Studio 12. You can get them here:
http://developers.sun.com/sunstudio/downloads/patches/
Please install the current C++ compiler patch, the C compiler patch, and the common back-end compiler patch.
You should then be able to build BOOST 1.37.0. The only problem I know of has been filed as CR 6767881, which results in an incorrect complaint about a constructor not being accessible. But I don't think that one affects regex.
If you running into some other problem after patching the compiler, please post enough detail that we can investigate it.
Questions about how to build just a portion of BOOST are probably best addressed to a BOOST forum.

But sorry for my insistence, but do you think that
purify or/and runtime are not able to detect any
corruption of the heap ?They can detect some kinds of corruption, such as some uses of an invalid pointer.
But a wild pointer that changes the value of data that is part of your program cannot be detected by RTC or Purify. Those programs can't know whether that change is intentional.
>
BTW, we are not using any volatile declaration, and weIf non-local data is shared among threads, it should be declared volatile. For example, suppose you have
x = foo;
... // code not changing foo
y = foo;
If foo is not marked volatile, the compiler is allowed to assume its value hasn't changed, and assign to y the same value assigned to x. If foo was changed by another thread, y will not have the current value of foo. The "volatile" declaration says that the variable's value might change without any obvious reason, and the compiler should generate code to load a fresh value each time it is referenced.
are using the rwtools library packaged with the
compiler, and are not using the STD library.OK, you are not running into a std::string synchronization bug.
>
Also about the compiler option -xarch=v8, is probably
not relevant for us because we are running Solaris 9.
So the relevant compiler is probably -xarch=v9. Do you
advise us using this option ?I think you misunderstand. The -xarch values refer to the kind of processor your program will run on.
The -xarch=v8 option generates 32-bit code that will run on all SPARC chips, including the chips found in very old SPARCstations. This option is the default for compilers prior to Sun Studio 9 (which ships this week).
The -xarch=v8plus option generates 32-bit code that runs only on UltraSPARC chips, found in Ultra workstations. These are the only kinds of workstations shipped by Sun since about 1996. Unless you need to support the ancient SPARCstations, we recommend compiling with -xarch=v8plus, to get smaller and faster code.
The -xarch=v9 option generates 64-bit code that runs only on UltraSPARC chips, an only on Solaris 7 or later. Unless your program requires a very large address space, you generally don't want to generate 64-bit code. On SPARC, 64-bit code is larger and slower than 32-bit code. (Type "long" and all pointers are 64 bits instead of 32 bits.)
>
Also I want to return you two new questions:
1) I read in another discussion,
http://forum.sun.com/thread.jsp?forum=5&thread=18124&me
sage=47854#47854
that another memory manager can be more efficient in
multi-threaded environment (libmtmalloc.so), and also
an alternate threads library (/usr/lib/lwp) that
reduced CPU usage. Do you advice us using this
alternate library ?The libmtmalloc library usually has better performance in MT programs than the default version of malloc. It also can result in more memory fragmentation. In that case, the larger working set can sometimes have a large negative effect, more than offsetting the MT efficiency. You have to experiment to see whether it is appropriate for your particlular program. If you are running into heap corruption, the pattern of corruption will probably be different with libmtmalloc than with the default malloc. The differences might provide a clue to what is wrong.
The alternative "T2" threads library was introduced in Solaris 8 as an option.
In Solaris 9 it is the default, so you are already using it.
>
2) We are using the Rogue Wave library shiped with the
compiler. Is it an up-to-date version ? Can we assume
that is a good choice or it will be preferable to move
to the STD library ?I assume you mean Rogue Wave Tools.h++. As explained in the compiler docs, this version of Tools is obsolete, and has not been supported for many years. We continue to provide it for customers who used it before the introduction of the C++ Standard Library in 1998, and who don't want to change their code. We do not recommend it for use in new code.

Two compile issues with Sun Studio 12 @ x86(_64 = amd64)

The following two issues are absent on Solaris 10 SPARC and all previous Sun Studio versions (8 to 11), but present on both amd64 Solaris 10 and Linux 2.6 versions:
1. mozilla.org's Spidermonkey "JavaScript" (ECMAscript) can't be compiled with it: in file jsinterp.c an endless loop is entered by the optimizer in level -xO1 and higher (!). With no optimization, linking is impossible (unresolved symbols from jsinterp.o), which hints to defunct output.
2. the optimizer (ube) is crashing in sources with a switch with many many case labels in optimization level -xO3 and higher with a segfault.

I have trouble to seperate a reasonable (example) source out of our complex sources showing the second issue --- what I can already tell is, that the following special pragma has to do with it (while I'm now in doubt that the each 256 case labels per switch, two switches in an if else clause have to do with it):
#pragma opt 0 (func_name)
Own1 Own2 func_name(...)
The buggy versions I can tell you: they are
on Solaris 10 amd64:
/opt/SUNWspro/bin/cc -V
cc: Sun C 5.9 SunOS_i386 2007/05/03
/opt/SUNWspro/prod/bin/ube -V
ube: Sun Compiler Common 12 SunOS_i386 2007/05/03

cc: Sun C 5.9 Linux_i386 2007/05/03
ube -V
ube: Sun Compiler Common 12 Linux_i386 2007/05/03
The only important compiler option in this regard seems to be the optimization level, but the situation is complex too, if others should be also involved. I will investigate further...

Hardware Acceleration for Linux with FireFox 4

'''Is this just a myth?'''
I am using Ubuntu 10.04 64-bit and FireFox 4 stable with a GT 240 and the latest nvidia binary driver. I have this set up as a HTPC through HDMI cable and have audio as well through the HDMI. It works wonderfully! I can watch x.264 and my intel celeron 2.8 GHz doesn't even get out of bed thanks to hardware acceleration.
Now, that is NOT the case while on the web... It is a tall order to watch HD quality flash (although with the [http://demos.hacks.mozilla.org/openweb/HWACCEL/ mozilla hardware stress test] I get 45 FPS). It seems to be that hardware acceleration is still very much in its infancy in the linux environment with firefox 4.
After searching through many threads I have come to find some useless information.
''MOZ_ACCELERATED=1 MOZ_GLX_IGNORE_BLACKLIST=1 firefox'' - does nothing
''layers.acceleration.force-enabled=true'' - does nothing
There seems to be an issue with firefox not recognising the installed graphics card. On Windows machines, the about:support page will report all the graphic card information in the Graphics section in addition to '''GPU Accelerated Windows 0/1''' or '''1/1'''. This seems to NOT be the case in linux. Why? Why doesn't firefox discover the installed graphics card?
Now, if I have missed a memo or been a total newb in this attempt to take advantage of Accelerated Hardware in FireFox 4 for linux '''PLEASE ENLIGHTEN ME''' as to what I need to do. If I have done all the things needed to achieve hardware acceleration and it is just not possible, than the good 'ol folks at mozilla should be a little more transparent when they proudly proclaim that they have released a hardware accelerated browser.
If anyone can shed some light on this predicament please post. If anyone has hit the same wall as I have please post... rant... w/e...

Poor performance of string::append on Solaris 10 with Sun Studio 10

I found string::append(size_type num, char ch) of libCstd consumes too much cpu time comparing with stlport. Anybody knows if this is a known issue on Solaris 10 and Sun Studio 10? Or if I need to use special build options to build with libCstd?
For example: a.c
#include <iostream>
#include <time.h>
using namespace std;
int main()
string ss;
for ( i=0; i<60000; i++)
ss.append(1, 'A');
cout << clock();
cout << endl;
return 0;
}Build with libCstd:
CC a.c -o a1
Build with stlport:
CC -library=%none -library=stlport4 a.c -o a2
a1 outputs: 10000
a2 outputs: 1900000
You can see how big different they have. I am sure their running environment is same.

I suspect this is due to a bug in libCstd that manifests itself by reallocating the string for each append. Compile and run the program below:
#include <string>
#include <new>
#include <stdlib.h>
int in_main;
void* operator new (size_t nbytes) throw (std::bad_alloc) {
if (in_main) printf ("operator new (%zu)\n", nbytes);
return malloc (nbytes);
void operator delete (void *p) throw () {
if (in_main) printf ("operator delete (%p)\n", p);
free (p);
int main () {
in_main = 1;
std::string ss;
for (int i = 0; i < 256; i++) {
printf ("append(1, 'A')\n");
ss.append (1, 'A');
in_main = 0;
}
