[gmx-users] mdrun exectutable

[Marilisa Neri]

I am trying to compile by hand the mdrun executable.  For this reason, 
I  have selected just the routines that I need.

I collected a list of file.c, file.h, and file.s .
I compiled the files .c and .s with this command:
(i) mpicc -c *.[cs] -I. -I /fftw-2.1.5/include/   -DHAVE_CONFIG_H  
-DGMXLIBDIR=\"/Software/gromacs-3.3.1/share/gromacs/top/\"
Then, I created the executable "my_mdrun" in this way:
(ii) mpicc *.o  -lm -L /usr/X11R6/lib -lXm  -L 
/home/marilisa/fftw-2.1.5/lib/ -lsfftw -ldrfftw -ldfftw -o my_mdrun
This procedure works with a 32-bits architecture.

When I running the command (i) with a 64-bits architecture, I have a 
problem with the routines: x86_3dnow.s, x86_cpuid.s, x86_sse.s.
The general error is:

x86_3dnow.s:104: Error: suffix or operands invalid for `push'
x86_3dnow.s:156: Error: suffix or operands invalid for `pop'
x86_sse.s:18151: Error: suffix or operands invalid for `pop'
x86_sse.s:18273: Error: suffix or operands invalid for `push'
x86_cpuid.s:73: Error: suffix or operands invalid for `push'
x86_cpuid.s:84: Error: suffix or operands invalid for `pop'

Someone could help me?

Thank you very much,
Marilisa
