32 bit app on 64 bit OS

Hi,
I'm pretty new to java and this is the first time i'm making a post here. I want to know, if i write a java program in a 32 bit environment will the same code work in a 64 bit Environment too. Does java abstract the architecture too?

Note for example that Sun supports 64 bit AMD processors but not Intel. But when they do your Java code will work without changes.

  • Problems with installing 32 bit app in 64 bit environment

    I have 64 bit ArchLinux installation and I'm trying to install IBM SPSS Statistics v20, but I get an error:
    Installer User Interface Mode Not Supported
    The installer cannot run in this UI mode. To specify the interface mode, use the -i command-line option, followed by the UI mode identifier. The valid UI modes identifiers are GUI, Console, and Silent.
    What can I do about it? Ubuntu solution on forums suggest that installing ia64-libs should solve the problem, but we don't have such package. Also, doing everything in the wiki for 32 bit apps doesn't help either.

    Did you try specifying the interface mode?
    If you don't tell people what you did...
    Of course I did. By using "-i Console", i. e., right? Then I tried all of the UIs.

  • 32 bit app on 64 bit WebLogic

    I have a 64 bit Microsoft 2008 r2 server running 64 bit WebLogic Portal 10.3.2 and now have a 32 bit application that needs to be deployed on it. The app requires 32 bit JVM. Can I install the 32 bit version of the jdk/jre and then create a 32 bit JVM (managed server) on a 64 bit WLP domain and run this app?

    Hi,
    Probably you can do it however its not recommended because of compatibility issues.

  • Running 32 bit apps in 64 bit mode

    Hi Everyone!
    I've just had my old (in relative terms - only 5months old) mac replaced by apple with a shiny new one (loving apple right now!)... which runs natively in 64 bit mode... This is a nice surprise... except for the fact that I can no longer run the cisco vpn client (the inbuilt snow leopard client doesn't work as we have old cisco hardware on the network I'm trying to get to... long story)...
    Just wondering if anyone knows how to run individual apps in 32 bit mode? I can't find what I need in the apple discussion forums or in google and I believe running the cisco client in 32 bit mode will solve all my problems...
    Thanks! & Much Appreciated

    Hi Lauren:
    Among other things, I am not a networking "expert." I did look at the Cisco web site and my eyes rolled around in my head. Perhaps there is something there that might help. Frankly, when I was working and had a VPN networking problem, I yelled for my IT people!

  • 32-bit apps on x86_64

    Hello, im a new to Arch
    I have a very newbish question and I guess it has been discussed many times already, but i was not able to find answer, so here i go
    I installed the 64-bit Arch linux (x86_64). It seems to run well except for that i have trouble running 32-bit apps.
    At first i tried a simple 32-bit app that only uses glibc. It said "no such file or directory" or something similar.
    After a bit digging i installed a 32-bit glibc. Fortunately the 32-bit glibc did not produce any file name clashes with the 64-bit glibc.
    The whole system continued to work and the simple 32-bit application now worked too.
    Then i tried some more complex 32-bit app, which uses other 32-bit libs (lile libX11).
    This time it did not say "no such file or directory" but complained about wrong ELF type or something like that.
    From that i comclude that now it finds a library with the wanted name, but it is 64-bit instead of 32-bit.
    So maybe if i try to install 32-bit variant there will be file name clashes.
    Is there a way to run _any_ 32-bit apps on x86_64 Arch linux? Maybe some compatibility package?
    If you suggest that i recompile my 32-bit apps to 64-bit, that is not that easy and sometimes it is impossible.
    For example i have some binary-only apps that are not open-source. Like, say, the game doom3.

    Xyne wrote:What system can run 64-bit and 32-bit apps natively at the same time? If you think another system is doing that for you then it's probably because it hides the 32-bit libs from you.
    If no distro can do what i want, then i guess i will have to stick to 32-bit linux for now. I'd hate the thought that half of my CPU stays unused tho
    Ranguvar wrote:Arch'll work fine. If you don't want a chroot, then just run the 32-bit app you want, look for its error message, and install that lib32 from the AUR. If there isn't one, make one - it's very simple.
    I think the problem with this is that both the 64- and 32-bit variants of some libs use the same name.
    Maybe if i put the 32-bits in a different dir (like /lib32 and /usr/lib32) and somehow explain to the 32-bit dynamic loader where to look for them (or patch it)?
    It would be best if it was possible to build the libs in a way to permit both 32-bit and 64-bit apps to link with them at the same time. Maybe provide 2 entry points for each exported function - one for 32-bit apps and another for 64-bit.

  • Premiere Pro CS4: 64-Bit App or Not?

    I read in the new Premiere Pro CS4 specs that it was "optimized for use on Win Vista 64-Bit..."
    Using that language, is Adobe saying it's still a 32-bit app, but will work fine on the Vista 64-bit platform? Would appreciate somebody clarifying that point.

  • In need of greater clarity on RAM and 64 Bit versus 32 Bit Apps...

    i have 13 GB of RAM in my MacPro, and i am running Leopard. i noted, however, that Adobe Photoshop only appears to recognize 3072 mb of RAM (3 Gb) as it is still a 32 bit program. 32 bit programs can still only recognize a max of 3 Gb of memory.
    i read somewhere that while Photoshop does not recognize all the RAM, that performance is increased even so, if you have more than 3 Gb of RAM; which would make sense as you can allocate that much to Photoshop and still have left over RAM for your system and other apps.
    When i noticed that Photoshop did not recognize all my RAM i was extremely disheartened. After all, i did splurge quite a bit on the RAM in hopes of dramatically increasing performance in Photoshop.
    But, as i think about it more, while Photoshop can only see 3 Gb of RAM, having 13 GB means that i can run more RAM intensive programs and each program will have enough RAM available. But i wonder what that means in terms of keeping up with the processors?
    i have been in the habit of closing most programs when working in a RAM intensive program such as Photoshop to improve performance. But, i am thinking that i no longer have to really worry about this?
    i would appreciate a discussion of this to add some clarity to the 32 bit/64 bit issue and RAM allocation on the MacPro.

    Hello Gene.
    My understanding is quite the same, 32bit programs theoricaly can't allocate more than 4G of RAM, maybe the 3G that you are talking about are anoter level of limitation, or caused by some allocations mechanisms beyond my knowledge.
    When using your computer, take a look at Activity Monitor, and see how much RAM is free. As long as you have enough RAM, there is no need to close applications, since the memory manager will not start swapping on disk. Well, that said, I think it may improbe performance to close application to avoid memory fragmentation, but the impact is not the same.
    And you're right, it is useless to have that much RAM for a single processus, but since Mac OS X has a pretty good multitasking, you can run lot of processes, each one allowed to use 4G of RAM, so that you keep performances even with lots of big applications launched.
    Now, be patient, and wait for a full 64bit version of Photoshop to really enjoy your RAM
    P.S. Maybe some plugins can detach new processes and get their own allocation space for some heavy filter operation ? If someone know, please clarify, that would be interesting.

  • 64 bit noob wants a 32 bit app... [SOLVED...for now!]

    I got the following when trying to install Google Earth:
    Uncompressing Google Earth for GNU/Linux 5.1.3533.1731...............................................................
    ./setup.sh: line 216: setup.data/bin/Linux/amd64/setup.gtk2: No such file or directory
    ./setup.sh: line 216: setup.data/bin/Linux/amd64/setup.gtk: No such file or directory
    The setup program seems to have failed on amd64
    Fatal error, installer failed to run at all!
    Is this just a question of trying to run a 32 bit app on a 64 bit OS?  And, if it is, how do I solve it?  Can I just install 32 bit libs (and which ones?) or must I do a 32 bit chroot for this...that seems rather a drag!  I've read the 64 fit FAQ, and can manage the chroot if I must...but it just seems like a lot of trouble.
    thanks,

    Thanks, tomk,
    I'm almost there.  Have read up on AUR, installed all the dependencies (I thought...at least, I installed all those on the page you sent me to, I was still missing
    Targets (2): lib32-libxfixes-4.0.4-1 lib32-libxdamage-1.1.2-1
    ) downloaded the tarball, unzipped it, ran makepkg...and exit with "no permission to create directory src in bin32-google-earth...etc."
    this was makepkg -s, with my password for sudo to work...no luck.
    so I checked up on fakeroot...and found that it appeared to be enabled in makepkg.conf...so ran makepkg without "-s" and got the same error.... 
    Thought I would be smart and just go ahead and make the directory /bin32-google.../src myself...and obviously didn't give it the right permissions, since when I ran makepkg again...still no luck, though the error has changed from can't create directory to can't download files into this directory...I can change that, too, but why is the fakeroot trick (or sudo, for that matter...) not working.  (It occurs to me that I may not be in sudoers...but I can fix that...and fakeroot ought to work anyway, shouldn't it?)
    many thanks, we're almost there and I'll be a little smarter for next time.

  • Opening CDR file - Extremely Fatal to CS6 64-bit apps

    I'm trying to get down the bottom of what's causing an extremely serious error in the 64-bit version of Adobe Illustrator CS6.
    Adobe Illustrator can open CorelDRAW .CDR files, to a certain extent. The .CDR files need to be saved down to version 9 or 10 compatibility. One of my coworkers just ran into a really bad Illustrator CS6 crash caused when opening a .CDR file. This is a crash I had to endure on my own new system a couple months ago.
    After Illustrator CS6 64-bit crashes it simply refuses to launch again. It crashes and closes. Rebooting doesn't help. Deleting the AI prefs file doesn't help. Worse yet, the crash basically hoses all of the CS6 64-bit apps that are installed. The 64-bit version of Photoshop CS6 crashes when opening a file.
    The last time this happened my only recourse was to do a "factory reset" on my computer, basically wiping the hard drive and reinstalling Windows 8 Professional in a clean state and then going through the very long, slow process of downloading and installing the CS6 apps from the Creative Cloud.
    Does anyone in this forum have any experience with this particular kind of crash? Are there any possible alternatives that might fix this error besides wiping the hard drive and starting over? This bug is pretty badly timed. Gonna have to go through all the download/install process stuff again when the new CC apps are released.

    The bug is unpredictable. Once the bug has occurred Adobe Illustrator CS6 64-bit will no longer launch. Rebooting and deleting the aiprefs file doesn't work. Additionally the bug also permanently affects other CS6 64-bit applications. Photoshop CS6 64-bit will launch, but it crashes when opening any file. After Effects and Premiere Pro crash at launch. No third party plug-ins were installed on this computer.
    Affected computer's hardware:
    Dell XPS 8500 Desktop
    • Core i7 3770 Quad Core 3.4GHz
    • 16GB RAM - Dual Channel DDR3 1600MHz - 4 DIMMs
    • nVidia GeForce GT640 1GB GDDR5 SDRAM
    • 2TB 7200rpm SATA 6 Gb/s Hard Disc
    • DVD-R/W Drive
    • 19 in 1 media card reader
    • Windows 8 Professional 64-bit
    When this bug affected my own workstation a couple months ago, I tried to uninstall Adobe Illustrator CS6, download it again and then reinstall. Illustrator CS6 64-bit still refused to launch. The other 64-bit apps wouldn't launch either. So I ended up wiping the hard disc, reinstalling Win 8 Pro clean and downloading/reinstalling everything and just being careful to not open any .CDR files after that. My workstation is a little better equipped (Core i7 3770, 24GB of RAM, BD-RW drive, nVidia GeForce 660GTX, Intel SRT solid state drive with SATA 6gb/s 2TB HDD).
    Previously I did run into problems when opening CorelDRAW .CDR artwork that was larger than a standard letter sized page. I would get hit with a dialog box saying "the file appears to be corrupt." I'd end up making CorelDRAW save the artwork into Adobe Illustrator CS5 format and then opening it Illustrator. Once my Adobe apps got hosed by a certain .CDR file I simply stopped trying to open any CorelDRAW files directly in Illustrator at all. Didn't want to go through the long process of reinstalling everything from scratch again. Unfortunately my coworker didn't remember the details of my experience. So now we're dealing with it on her new machine.
    My coworker said she thinks she remembers which .CDR file caused Illustrator CS6 64-bit to crash. Here's a Dropbox link to it:
    https://dl.dropboxusercontent.com/u/86940762/V130520-1%20CC%20expo%20center%20billingsley% 20ford%20FS.cdr
    Warning: I do not recommend other users to try opening this CorelDRAW file within Adobe Illustrator CS6. I'm sure not trying it on my installation!
    This particular .CDR file doesn't have any active type in it. But it does feature some strange clipped gradient effects. I think some of this artwork was originally created in Illustrator and then saved in CorelDRAW. I'm wondering if there is some sort of way Corel tried to reinterpret the artwork that caused Illustrator to lose its mind when reopening it. If memory serves correctly I was opening some similar Illustrator-generated and then Corel-saved art in my own copy of AI CS6 64-bit when it crashed.

  • 32-bit Windows 7 app on 64-bit platform oddity

    An application compiled for a 32-bit platform runs correctly with an SDK that is compiled for 32-bit only, either in debug or release mode from Visual C++ Express 2008, on a 64-bit computer.
    The target platform in the compiler options is set as X86. The compilation is for Win32. 
    However, when the release version is run outside of Visual C++ - that is, on its own, as an app - the SDK thinks the app is 64-bit, and returns an error of "not supported" (the SDK error message).
    The application is mixed unmanaged and managed code, where the bulk of the routines are unmanaged with #pragma unmanaged at the top of the file after includes. The managed code portion is just for a few routines to use the MicroChip software. Thus
    the code is compiled with the /clr option. 
    The application interfaces to a number of other 32-bit DLLs with no problem. The application has been working fine under all of these conditions for some time, and in different installations.
    However, the new SDK that was just recently added, appears  to be using some information somewhere to think it is running 64-bit, in stand-alone release mode only. It works fine when run under Visual C++ either in debug mode or release
    mode.
    I have looked all over for any other option that needs to be set to 32 bit for the SDK to know that it is working in a 32-bit app, albeit on a 64-bit platform. (There is no support for the SDK.)
    Are there any computer settings that have to be changed?
    Thanks for any suggestions.  Btw, the problem also occurs on VC ++ 2010 Express.

  • Command-Key etc to start an App in 32-bit mode?

    Is there some sort of Command-Key etc to start an App in 32-bit mode, without having to go to "Get Info" ?
    I have a Canoscan scanner which only runs in Photoshop under 32-bit mode. It would be nice to be able to launch PS into 32-bit mode when I need to, without going to Get Info.

    Hi,
    This AppleScript script doesn't change anything in (Get info), but launch the application in 32-bit mode.
    property appName : missing value
    property tpath : missing value
    if appName is missing value then
          tell application "Finder"
                set appName to text 1 thru -5 of (get name of (application file id "com.adobe.Photoshop"))
                (application file id "com.adobe.Photoshop") as text
          end tell
          set tpath to quoted form of (POSIX path of (the result & ":Contents:MacOS:" & appName))
    end if
    get running of application appName
    if the result then
          quit application appName
          tell application "System Events" to repeat while exists process appName
                delay 1
          end repeat
    end if
    do shell script "arch -i386 " & tpath & " > /dev/null 2>&1 &" -- launch (32-bit mode)
    delay 1.5
    activate application appName
    Quit the application and restart to run in 64-bit mode.
    To have a keyboard shortcut to run this script: you have some solutions
    First solution: Make a service with Automator.
    Second solution: There are some third party utilities that launches script, and you can set a keyboard shortcut.

  • Using long longs in a 32 bit app

    What restrictions do I need to observe if I use long long ints (or off_t or fpos_t) in a 32 bit app? If I return a 64 bit value from a function, will that change the alignment of all function calls in the project? Can I use structs that contain long longs without affecting call alignments?

    I don't have another
    compiler/debugger to use, but I make more progress by
    inserting my own debugging statements than with GDB.
    You're not the only one!
    If there is an alignment problem, the source is probably not in GCC. Even though using a long long is a little unusual for people like me, I'm sure there are enough people using long long in GCC to have worked out the bugs.
    Are you doing pointer arithmetic? Are you assuming that the way you have defined your C structure is the way it looks in memory? Is it possible you have endian issues?
    I would suggest starting a new thread. I think the only thing you've done wrong is assume that it is an alignment issue with GCC/GDB and asked a specific question about that. If you frame your question in terms of "I'm crashing here - anybody know why?" you'll get better responses. Of course, the ideal is a very small piece of runnable code the reproduces the error. I know that is usually not possible, but try the best you can. If nothing else, post the structures as you define them and then post some code examples of how you pass them and then how you use them.
    Switching to C++ is another can of worms you probably don't want. I would rather see you use C than Python or Java. Just post some source code here or in a new thread and we'll take a look at it. Having another set of eyes makes a huge difference.

  • Update both CS6 and CS6 64-bit apps?

    Adobe Application Manager is showing updates for both regular CS6 and CS6 64-bit versions of Creative Suites apps like Illustrator, Photoshop and Dreamweaver. These were both automatically installed on my system when I downloaded from the cloud. Do i need to update both? Do I even need to have both on my system?
    Thanks.

    The Cloud installer installs both 32 bit and 64 bit versions of some apps on 64 bit systems because we're in a transition between 32 bit and 64 bit computing.
    Soon 64 bit will be everywhere. Until then some people with 64 bit systems still need occasional access to 32 bit plugins (TWAIN for scanning comes to mind http://helpx.adobe.com/photoshop/kb/twain-plug-photoshop-cs4-cs5.html) which have not yet been upgraded to 64 bit by the plugin vendor. So they open 32 bit Photoshop, run their filter then close it and launch 64 bit Photoshop.
