Re: [Valgrind-users] compiling with MPI support on OS X Lion

Hi Julian,

I tried the downloading from svn and still no luck, except that now it is detecting the failure in the configuration stage:

configure:11126: /Users/bhelenbr/Packages/bin/mpicc -o conftest -g -O -fno-omit-frame-pointer -Wall -dynamic -m64 -arch x86_64  -dynamic -dynamiclib -all_load -m64 -arch x86_64 conftest.c  >&5
configure:11132: $? = 0
configure:11140: result: yes, /Users/bhelenbr/Packages/bin/mpicc
configure:11173: checking secondary target for usable MPI2-compliant C compiler and mpi.h
configure:11215: /Users/bhelenbr/Packages/bin/mpicc -o conftest -g -O -fno-omit-frame-pointer -Wall -dynamic -m32 -arch i386  -dynamic -dynamiclib -all_load -m32 -arch i386 conftest.c  >&5

collect2: ld returned 1 exit status
configure:11221: $? = 1
configure: failed program was:

lots of defines…..

configure:11238: result: no

I don't know why it tries to switch to the i386 architecture.
