Problem:
All my results fail with a message saying that the application died prematurely or a segfault, but the message does not talk about link libraries.
It seems "Glue" starts up but the renderer fails. What is going on and what can I do about it?

Example error output:

[...]
CHMODing executable...
CHMODing preloader executable...
Creating worker...
Worker constructing...

Answer:
The official linux client is compiled for kernel above 3.11.x glibc >= 2.11 systems with recent libraries installed. Your message indicates that "Glue" is working fine but the renderer is failing to start up with the bundled libraries.
Sometimes the libraries that are bundled with the client simply don't work well with the libraries installed on the machine. In that case you can disable the bundled libraries and install and use your own:
1) Install the renderer through your system's package manager (for example: apt-get install blender)
2) Go to the boinc project folder (typically something like /var/lib/boinc-client/projects/burp.renderfarming.net)
3) Create a file called "native"
4) Restart BOINC. It should now say something along the lines of "NOTE: Skipping preloader, using native libs!" when it starts a workunit instead of "CHMODing preloader executable..."

As an alternative to 1 you can also unpack the blender?.zip in the project directory and run "ldd ./blender" on it to get a list of libraries and see which ones are missing. Install the missing libraries (if any) and then proceed to 2 and 3.

I'm using native mode (above) and all my results fail with a message talking about link libraries, shared objects or segfaults. It seems "Glue" starts up but the renderer fails. What is going on and what can I do about it?

Answer:
Your message indicates that "Glue" is working fine but the renderer is missing some libraries or some of the supplied libraries didn't work well with what else is on your system.
Make sure that all required libraries are available.
If it still fails you may have to compile a custom version of it.

Problem:
All my results fail with a message talking about link libraries or shared object files. The error does not say anything about 'Glue'

Example error output:

:/ error while loading shared libraries: libpthread.so.0: cannot open shared object file: No such file or directory

Answer:
The official binary of Glue is statically compiled with stdc++ and glibc and only requires the following standard libraries:

• linux-gate.so.1
  
• libpthread.so.0
  
• libm.so.6
  
• libc.so.6
  
• /lib/ld-linux.so.2
  

There's a pretty high chance that you already have some version of these libraries installed (otherwise almost no program would work) but your library versions may be incompatible with the ones used to compile Glue (or the statically linked glibc or stdc++ may be incompatible with your kernel). In this case you will have to compile Glue for your specific system. Don't be afraid it isn't as bad as it sounds:
1) Go to "Help us code" and download the Glue client-side sourcecode.
2) Follow the instructions in "INSTALL" on how to compile the code on your system.
3) Copy the compiled executable to the BURP project directory in the BOINC folder.
4) Use the anonymous platform mechanism to use the newly compiled Glue code

Please only reply to this thread if you have any additions to the Linux portability FAQ - if you have issues compiling for linux please create a new thread (or search and use an existing thread) instead.
