I can run xlc as it is in /usr/bin. But in that folder there is no xlC_r and there are only xlc and xlc++. The administrator knows little about the cluster and did not want to compile it. So I used gcc instead.

In that case, you should be able to modify the variables in charm-6.4.0/src/arch/lap/cc-xlc.sh to refer to xlc and xlc++ instead of xlc_r and xlC_r. You may need to do the same to the NAMD 'arch' files that Jim mentioned as well.

Thank you!

My command:
 ./build charm++ lapi xlc        --with-production

But there is problem with our unix:

../bin/charmc -host  xi-main.C
../bin/charmc[2]: xlC_r:  not found.
Fatal Error by charmc in directory /rc/home/wang/mzhu6/bin/NAMD_2.9_Source/charm-6.4.0/lapi-xlc/tmp
   Command xlC_r -q32 -D_H_UNISTD -DYY_NEVER_INTERACTIVE=1 -I../bin/../include -D__CHARMC__=1 -c xi-main.C -o xi-main.o returned error code 127
charmc exiting...

Is your xlc installation's bin/ directory in your path? You can run 'echo $PATH' to see.

You could drop the 'gcc' and 'gfortran' options, and use the default xlC compiler toolchain. I believe that is expected to provide better performance on POWER hardware, though the NAMD developers would have to confirm that.

So that we can fully understand your situation, could you please describe what resources led you to choose the lapi-gcc-gfortran build target?

Dear,

As I want to compile NAMD2.9 in AIX UNIX, I have to compile charm first.

This is my command:
./build charm++ lapi gcc   gfortran     --with-production

This is my error:

g++: error: unrecognized command line option '-qstrict'
Fatal Error by charmc in directory /rc/home/wang/mzhu6/bin/NAMD_2.9_Source/charm-6.4.0/lapi-gfortran-gcc/tmp
   Command g++ -fPIC -Wno-deprecated -DCMK_GFORTRAN -I../bin/../include -D__CHARMC__=1 -I. -O3 -qstrict -Q -c trace-common.C -o trace-common.o returned error code 1
charmc exiting...

What can I do?

Best regards,

Mengyuan Zhu
