[gmx-users] SGI installation problem: forcing the compilation with gcc

[dastmalchi.s at tbzmed.ac.ir]

Hi Erik,

I am not sure if this is right but I have changed the
       gh      = mk_rgrid(ix,iy,iz);
to
       gh      =(real ***)mk_rgrid(ix,iy,iz);

in the source file ghat.c and it was compiled.
then I got the error compiling gmx-_fft_fftw3.c file:

cc-3316 cc: ERROR File = gmx-_fft_fftw3.c, Line = 100 (and many other
lines as well)
The expression must be a pointer to a complete object type.

     pv += 8;
     ^
...
...
12 errors detected in the .....


Finally I gave up and installed version 3.1.4 of gromacs.

Cheers, Siavoush
