[gmx-users] compiling error in tools

[Jennifer Williams]

Hello

I know this is possibly an issue for the IT support at my Uni but I  
was wondering if someone could shed some light on what may have gone  
wrong so at least I can point them in the right direction.

As I am getting very small diffusion coefficients when using g_msd, I  
want to increase the number of decimal points the diffusion  
coefficient is displayed to.
In the file gmx_msd.c within src/tools I changed

  fprintf(out,"# D[%10s] = %.4f (+/- %.4f) (1e-5 cm^2/s)\n",

to

  fprintf(out,"# D[%10s] = %.8f (+/- %.8f) (1e-5 cm^2/s)\n",

then, as I have always done, I just typed in make g_msd to recompile  
this tool.
I get the following error message:

collect2: ld returned 1 exit status
make: *** [g_msd] Error 1

The compile seems to need some mpi files but shouldn't the tools  
compile in serial rather than parallel? I have recompiled in tools  
before and everything has worked previously. Any advice appreciated.

Thanks
