Hi all, I installed gnu-gcc-4.4.3 on our Mac and found out openMPI didn't work any longer. I tried a lot of things to install openMPI back but failed. I installed the new gnu-gcc-4.5 and got similar problem.
I followed the information on this mailing list and used option "-arch x86_64" for compilers to try to get rid of the following error: as: more than one -arch option (not allowed, use cc(1) instead) make[2]: *** [coll_hierarch.lo] Error 1 make[1]: *** [all-recursive] Error 1 make: *** [all-recursive] Error 1 I tried two ways: 1. ./configure --prefix=/usr/local/openmpi --enable-static CC=gcc FC=gfortran F77=gfortran CXX=g++ CFLAGS="-arch x86_64" CXXFLAGS="-arch x86_64" FCFLAGS="-m64 -arch x86_64" FFLAGS="-m64 -arch x86_64" --with-gnu-ld Configure failed. It seems the configure doesn't recognize the option -arch x86_64 Then I did 2. export CFLAGS="-arch x86_64" export CXXFLAGS="-arch x86_64" export FCFLAGS="-m64 -arch x86_64" export FFLAGS="-m64 -arch x86_64" export OBJCFLAGS="-arch x86_64" export DYLD_LIBRARY_PATH=/usr/local/gcc-4.5/lib/gcc/x86_64-apple-darwin10.2.0/4.6.0/include ./configure --prefix=/usr/local/openmpi CC=gcc FC=gfortran F77=gfortran CXX=g++ --with-gnu-ld Configure passed but it gave same making error. Any hint? Thanks, Bill
