Subject: [OMPI docs] Open MPI compilation Error
From: Rashid, Z. (Zahid) (Z.Rashid_at_[hidden])

Dear Open MPI users,

I am trying to compile open MPI (release 1.5.4) from the source code on a Macbook Pro (OS X Lion) with Xcode 4.1 installed. I configure the openmpi with the following options;

../configure CFLAGS=-m64 CXXFLAGS=-m64 FFLAGS=-m64 FCFLAGS=-m64 --with-wrapper-cflags=-m64 --with-wrapper-cxxflags=-m64

in a new/clean directory. When I try make it gives me the following error;

    Making all in otfprofile
  CXX otfprofile-otfprofile.o
  CXX otfprofile-CSVParse.o
  CXX otfprofile-DataStructure.o
  CXX otfprofile-Handler.o
  CXX otfprofile-Prodtex.o
  CXX otfprofile-Summary.o
  CXXLD otfprofile
Undefined symbols for architecture x86_64:

make[3]: *** [all] Error 2
make[2]: *** [all-recursive] Error 1
make[1]: *** [all-recursive] Error 1
make: *** [all-recursive] Error 1

I have gcc version 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2335.15.00), gfortran GNU Fortran (GCC) 4.2.1 (Apple Inc. build 5666) (dot 3) I heard that I can use MacPorts for an easy installation but I want to compile it myself from the source. Can someone suggest me if I need to set some extra flags or what is causing this error? Please let me know if you need any further information.

Regards.
