[gmx-users] MPICH2 error

[Souparno Adhikary]

I am posting this error again. Please help. I installed mpich2 with
CXXFLAGS='-fPIC' and --enable-shared options.

I configured gromacs with the following command:

/root/cmake-3.9.1-Linux-x86_64/bin/cmake .. -DGMX_BUILD_OWN_FFTW=ON
-DREGRESSIONTEST_DOWNLOAD=ON -DGMX_MPI=ON
-DCMAKE_INSTALL_PREFIX=/usr/local/gromacs-5.1.4

After I ran make, I am getting the following error:

/usr/bin/ld: /usr/local/lib/libmpich.a(allreduce.o): relocation R_X86_64_32
against `.rodata.str1.8' can not be used when making a shared object;
recompile with -fPIC
/usr/local/lib/libmpich.a: could not read symbols: Bad value
collect2: ld returned 1 exit status
make[2]: *** [lib/libgromacs_mpi.so.1.4.0] Error 1
make[1]: *** [src/gromacs/CMakeFiles/libgromacs.dir/all] Error 2
make: *** [all] Error 2

Can anyone please help???
