[Pypar-developers] Fwd: Problems with pypar & MPICH2

[Ole N. <ole...@gm...>]

Hi guys

This sounds like the problem you had?

Is this something with recent MPICH versions perhaps?

Cheers
Ole

Hi,


I'm trying to add MPICH2 support to the Fedora package of pypar, however
the compilation fails with

mpicc -DNDEBUG -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions
-fstack-protector --param=ssp-buffer-size=4 -m64 -mtune=generic
-D_GNU_SOURCE -fPIC -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2
-fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64
-mtune=generic -fPIC -I/usr/include/mpich2-x86_64
-I/usr/lib64/python2.6/site-packages/numpy/core/include
-I/usr/include/python2.6 -c mpiext.c -o
build/temp.linux-x86_64-2.6/mpiext.o -fPIC
mpiext.c: In function 'type_map':
mpiext.c:127: warning: return makes integer from pointer without a cast
mpiext.c: In function 'op_map':
mpiext.c:168: warning: return makes integer from pointer without a cast
gcc -pthread -shared -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2
-fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64
-mtune=generic build/temp.linux-x86_64-2.6/mpiext.o
-L/usr/lib64/mpich2/lib -L/usr/lib64 -lmpich -lopa -lpthread -lrt -lopa'
-lpython2.6 -o build/lib.linux-x86_64-2.6/pypar/mpiext.so
/usr/bin/ld: cannot find -lopa'
collect2: ld returned 1 exit status

so it seems that an extra ' is picked up somewhere. Do you have any idea
where this might come out from?

Also, although I've defined CC=mpicc, the file is compiled with gcc..
