Re: AMBER: Problems compiling amber9

Dear Amber Users,

I am having the same problem as Thomas Steinbrecher (Fri Apr 21 2006, )
while trying to compile Amber9.
My system is running:
   Scyldsmp 2.4.22-9
   gcc 2.96
   ifort 9.0
   icc 9.1.038
   mkl 8.1

I've tried with both icc and gcc; no difference.

configure runs fine
$ ./configure -p4 ifort_ia32
AMBERHOME is set to /usr/local/amber9
Setting up Amber configuration file for architecture: ifort_ia32
Using parallel communications library: none
MKL_HOME is set to /opt/intel/mkl/8.1/
Using MKL libraries from /opt/intel/mkl/8.1//lib/32
The configuration file, config.h, was successfully created.

However the compilation dies with gcc -m32 -c -D_FILE_OFFSET_BITS=64
-D_LARGEFILE_SOURCE -O2 -o mmtsb_client.o mmtsb_client.c
cc1: Invalid option `32'
make[1]: *** [mmtsb_client.o] Error 1
make[1]: Leaving directory `/usr/local/amber9/src/sander'
make: *** [serial] Error 2

Removing the -m32 flag at CC and LOADCC in config.h allows amber to
compile, but the test suit dies. Has anyone found a resolution? My
guess is that my gcc is too old.
