Re: [opensuse] glibc compatibility

Hello everyone,


we're experiencing segfaults in binaries created on openSUSE 10.2 when
run on 11.1 systems. These occur in getpwuid(), so I am wondering what
the expected compatibilty between glibc versions is -- shouldn't the
linker complain if the user tries to execute a binary that's too old?

When compiling on 11.1 and executing on 10.3, the linker gives an error:
: lee$; /usr/local/gromacs/405/fftw312-gcc412/bin/pdb2gmx -f 1UBI.pdb

/usr/local/gromacs/405/fftw312-gcc412/bin/pdb2gmx: /lib64/libc.so.6:
version `GLIBC_2.7' not found (required by /usr/local/gromacs/405/
fftw312-gcc412/bin/pdb2gmx)

A quick check seems to indicate that 11.0 will run binaries compiled
on either 10.2 or 11.1, so we have some leeway. Is there any hope to
compile a binary that will run on both 10.3 and 11.1?

A binary compiled with an older glibc should run with a newer glibc. Seeing a
failure in getpwuid points to one of the exceptions: Static binaries using NSS
code like getpwuid might not work. If you only use shared objects you're fine
in general.

So, compile on 10.2 dynamically and it should run on 11.1,
Andreas
