Debian is not supported by the PathScale compiler.
Thanks for your answer. In the meantime I have found a workaround for my situation, but I'll answer for the sake of the e-mail archives.
which one is is being used? The new Debian etch 64bit has minimal support for 32 bit user space programs by default. It may be necessary to install 32 bit libs and or compatability libs to get it to run correctly.
It is indeed the 64bit version. However I was able to use the PathScale compiler to compile other applications without problems, so it was a specific interaction, probably with the threading support, that was triggered by Open MPI which showed up. I guess that if the necessary libs would be missing, the compiler wouldn't work at all or ldd would show missing libs for the other executables that the compiler produced.
I do not know which gcc compiler suite Debian GCC is based on.
gcc version 4.1.2 20061115 (prerelease) (Debian 4.1.1-21)
In RHEL4 compare and contrast gcc4-4.1.1-53 .vs. gcc-3.4.6-8. The Pathscale compiler is recently rebased to also work with gcc4 based systems.
Should I understand from this statement that the PathScale compilers version 3.0 are only compatible with gcc 3.4 and not with gcc 4.1 based systems ?
Do foundation Open MPI tools like .../bin/orterun compile and run well enough to return errors?
They compile fine, but they give segmentation faults when run.
Scan the eko man page for PathScale compiler specific options.
I don't quite understand what you mean here... especially what 'specific options' refer to.
ompi_info does not capture compiler flags so report your configure line, make line and environment variables.
One of my earlier messages already included the configure line; the environment is only modified to set CC=pathcc, etc. and there are no options on the make line; just like the documentation says that I should do...
