[gmx-users] Installation on IBM AIX

[Li Zhenhai]

Dear gmx users:

	I asked my question days ago, but no body answers me. So I think I should make my question compacter.

	I met a trouble when I installed Gromacs on IBM A.I.X 5.2.0.0. So I want to list my problem here beging for your helps.
	
	I start my installation as:

export CC=xlc;
export MPICC=mpcc;
export F77=xlf;
export CXX=xlC;
export CFLAGS="-O3 -qarch=pwr4 -qtune=pwr4 -qansialias -w"
export FFLAGS="-O3 -qarch=pwr4 -qtune=pwr4 -qansialias -qstrict -w"
export CPPFLAGS=-I .../fftw312/include
export LDFLAGS=-L .../fftw312/lib

./configure --prefix=.../gmx33 --exec-prefix=.../gmx33 --enable-float --disable-fortran --disable-largefile --without-x --disable-vectorized-sqrt
make

	It stoped here with saying:    
"gmx_fft_fftw3.c", line 186.8: 1506-068 (S) Operation between types "void*" and "int" is not allowed.
"gmx_fft_fftw3.c", line 190.8: 1506-068 (S) Operation between types "void*" and "int" is not allowed.

	If I install a parallel Gromacs. It cannot finish the "configure" step with saying:

	"cannot calculate the sizeof (int)"
	
	I checked the config.log, and found that there was some problem on "conftest.c".

    And I also change the environment as below, but I met the same error.

export CC=xlc;
export MPICC=mpcc;
export F77=xlf;
export CXX=xlC;
export CFLAGS="-O2 -qarch=pwr2 -qtune=pwr2"
export FFLAGS="-O2 -qarch=pwr2 -qtune=pwr2"

	Could anybody here help me? Any more ideas would be very much appreciated.
