Linux x86 32/64: issue with file > 2gb
location: linuxquestions.com - date: October 15, 2009
In our product, we have a limitation that tmp file(file created in /tmp folder for dumping data retrieved from db) cannot be written more than 2gb size. So in order to increase it to write till 4gb, we changed mainly in our code from fseek to fseek064. When we tried to execute this code compiled with ICC v184.108.40.206, it worked fine. But when we used 7.1.032, it fails exactly when temp file reaches 2g size. The error returned from fseeko64 is "2" which seems to be "No such file or directory". This doesn't seem to make any sense. Also we are not sure whether compiler version has any role here to play.
I have added 2 required compile time flags -D_LARGEFILE64_SOURCE=1 & -D_LARGEFILE_SOURCE=1 for compiling with ICC compiler. The same code works fine with Solaris but not on Linux x86 32bit/64bit.
I use Red Hat Linux x86 32bit/64bit.
Can anyone suggest what could be wrong here? Is there any other way to get rid of this situation? Any pointers please?
How to get 32 bit JRE path on 64 bit Linux with 64 bit browser and 64 bit java plugin
location: linuxexchange.com - date: May 11, 2012
My application consists of three components:
Java program (myapp.jar)
JNI library (myjni.so)
Please note that JNI library is built for 32 bit. On 32 bit OS, applet uses java.home property to get the JRE path. Once applet gets JRE path, it launches JAR like this
Now I need to run this application on 64 bit Linux. Here I have two options:
Build JNI library for 64 bit.
This is not possible as all depended libraries needs to build for 64 bit. ( This is a constraint at my end)
Ask users to install 32 bit JVM
Now problem is how to get the 32 bit JRE path as java.home property gives the 64 bit JRE path. ( Because browser and plugins are 64 bit). One option is to use update-alternatives –list java command to get all JRE installations path. Then for each installation path, run JRE-path -d32 –version command to see whether it supports 32 bit JVM
If it supports 32 bit JVM, use that JRE path to launch JAR file
If none of the java installations s
[SOLVED] Installing 32 bit RPMs on 64 bit Linux conflicts with 64 bit packages
- date: August 18, 2011
I'm using a 64 bit Linux server (OEL 6.1):
~]# uname -r
I was trying to install Oracle Database on this server that I realized the installer requires some 32 bit libraries. For instance it was looking for libXp.so.6 which existed under /usr/lib64, but not /usr/lib.
Even when I changed the installation script to look into lib64 for the library, it failed with an error from Java that it needs 32 bit and instead has found 64 bit.
I downloaded a bunch of 32 bit RPM packages and when I tried to install them, I got the error that a newer version of those packages is installed, which is not the case. Cause all previously installed packages are 64 bit. I was wondering why it thinks that 64 bit packages are newer version of 32 bit packages. And is there a way to solve this?
~]# rpm -ivh libXp-1.0.0-8.i386.rpm xorg-x11-Mesa-libGL-6.8.2-31.i386.rpm xorg-x11-libs-6.8.2-31.i386.rpm expat-1.95.8-9.i386.rpm libXau-1.0.1
cant get 32 bit java extension to work on 64 bit java on OpenSUSE
location: linuxquestions.com - date: September 5, 2012
I'm writing a java application which uses the CDDA plugin for tritonus (tritonus.org), which is only available in 32 bit. whenever it tries to access the plugin, it throws a java.lang.UnsatisfiedLinkError, because it cant find the plugin. to solve this, i think i need to either:
install 32 bit java alongside 64 bit java, and find some way to specify which to use whenever i use a java program, none of which i know how to do, or
find some way to run the java program in 64 bit, but run the extension in 32 bit, which i'm not sure is possible but would be the desirable situation, or
compile the plugin for 64 bit, which i dont know how to do or if it is possible, but the source code is available

I am having trouble installing SUSE Linux 10.0 on my 64 bit computer. When I boot from the DVD it comes up with a notice saying I am about to install a 32 bit software on a 64.After that I click on installation and it froze. Any suggestions on what to do next? Thanks in advance.
Ok so what all can I not get for 64 bit Linux systems?

I just learned that Java & Flash don't work on 64 bit Linux systems.
What else out there only works for 32 bit Linux systems?
This stinks to high heaven.
How to determine whether a given Linux is 32 bit or 64 bit?
location: linuxexchange.com - date: December 8, 2011
When I type uname -a, it gives the following output.
Linux mars 2.6.9-67.0.15.ELsmp #1 SMP Tue Apr 22 13:50:33 EDT 2008 i686 i686 i386 GNU/Linux
How can I know from this that the given OS is 32 or 64 bit?
This is useful when writing configure scripts, for example: what architecture am I building for?

Server/client 32/64 bit
location: ubuntuforums.com - date: March 28, 2013
Hi, I am pretty new to Ubuntu and I am thinking about creating a home server but I have both 32 & 64 bit computers I would like to connect to it...
Can I do this?
I could run the server OS on a 32 or 64 bit PC, but I don't know whether only 32bit can connect to 32bit server etc as I've never played with servers before or if any particular setup would be best.
I am running ubuntu 12.04.02 LTS (one on 32bit, one on 64bit) and was going to use ubuntu 12.04 server maybe?
Any help would be appreciated.
Can Linux get a virus?
location: ubuntuforums.com - date: May 17, 2009
I have never gotten a virus with Linux, but is it possible? I know every machine has 0.1% or more of chance of getting a virus, but is linux near the 0.1%?
