Hum - XCode 3.2.3... Apple made some significant changes in their linker beginning in version 3.2.2. Significant enough that all of our Intel compiled builds started Seg faulting for those who clicked the automatic update from Apple. I didn't do extensive testing with GNU at the time but instead froze our site to XCode 3.2.1 after recognizing the cause of the problem. I believe that we have had success with at least 3.2.2 and 4.5 but I'm not sure if anybody has used GNU with the new XCode for sure yet at least in our group.
More interesting data... Intel is aware that there were linkage issues regarding their fortran compiler and supposedly patched and released an update for XCode 3.2.2+ users. I tried the new compiler + current XCode yesterday on a clean system and was met with 100% segfaults in all libmesh examples in opt and debug mode. Reverting to a previous version of XCode does fix the problem... Note that this is for Intel compilers but it still could have negative impacts on any non-Apple compilers for all we know. Right now I don't have a lot of time to work on the issue so let me instead tell you what does work until somebody can get to the bottom of the problem. GCC 4.2-4.6 all work with XCode 3.2.1 and earlier. On my laptop right now I have Xcode 3.2 and GCC 4.5 and it does work. Here is my configure line for mpich2 which we have been using for quite some time. ../configure --prefix=/opt/packages/mpich2/mpich2-1.2.1/gnu-opt --enable-sharedlibs=osx-gcc CC=gcc CXX=g++ FC=gfortran F90=gfortran F77=gfortran CFLAGS= CXXFLAGS= FFLAGS= FCFLAGS= F90FLAGS= F77FLAGS= MPICH2LIB_CFLAGS=-O3 MPICH2LIB_CXXFLAGS=-O3 MPICH2LIB_FFLAGS=-O3 MPICH2LIB_F90FLAGS=-O3 My build is a little more vanilla than yours - note that I don't have any extra "enables" in my build with the exception of the sharedlibs. My path is correct to pick up the HPC version of the GCC compilers NOT THE APPLE versions. Finally all the extra flags are there to make sure I don't put any flags into wrappers but that I can still compile the library itself in optimized mode. I hope this helps, Cody On Sep 10, 2010, at 2:46 PM, Anna-Lena Gerner wrote: > > On 10 Sep 2010, at 16:30, Cody Permann wrote: > >> It could be some XCode issue.
