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?
