Find the _last_ error in config.log, and check what the compiler said
about it.
Cheers,

Dear Erik:
I have carefully read through config.log file, and I found out some
possible problems for compilation failure, could you please help me
to locate the real reason and solution?
As I think, maybe this error is from xlc, but it seemed much
related to "conftest.c" file, which was reported for several times
as errors.
How should I deal it with? By the way, I have passed through the
compilation of single version. The following errors were from MPI
compilation. Of course, I only added a "--enable-mpi" flag when
compling MPI version, as described in the last email.

Hi,
Check config.log for the actual error. You might also want to make
sure that you can compile a small MPI test program.
Cheers,
Erik

Dear users:
I have successfully installed fftw2.1.3 and single version
Gromacs3.3 on IBM powerpc Aix5.2.0.0 with the following
environmental variables:
setenv CC xlc
setenv MPICC mpcc
setenv F77 xlf
setenv CXX xlC
setenv CPPFLAGS -I.../fftw_213/include
setenv LDFLAGS -L.../fftw_213/lib
setenv CFLAGS "-O3 -qarch=pwr4 -qtune=pwr4 -qansialias -w"
setenv FFLAGS "-O3 -qarch=pwr4 -qtune=pwr4 -qansialias -qstrict -w"
Now, I would like to compile the parallel version of Gromacs3.3,
and I did it as the follows:
1. make disclean;
2. ./configure --prefix=$HOME/gromacs33 --exec-prefix=$HOME/
gromacs33 --enable-float --disable-fortran --disable-largefile --
without-x --disable-
vectorized-sqrt --with-fft=fftw2 --enable-mpi --program-suffix=_mpi
It is worthy noting that the all parameters for ./configure are the
same as perviously successful single version, except that "--enable-
mpi --program-suffix=_mpi" is added in compiling MPI version.
However, compilation can not pass because of the following reason.
If anybody encountered such an error, could you give me some
suggestion? How to deal with it? Any help will be extermely
appreciately.
