FWIW, this is also on Lion: (yt-x86_64)goldbaum@~/Documents/yt-x86_64/src/yt-hg: gcc --version i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.1.00) yt builds fine for me from scratch. On 7/17/12 6:15 PM, Sam Skillman wrote:
Hi Carolyn,
This is the thread I was referring to before: http://lists.spacepope.org/pipermail/yt-dev-spacepope.org/2012-June/002134.h...
It seems something is messed up in the build for new macs. I can try to find the issue tomorrow but could you try what Dave did in that thread?
The 4.2 compiler that comes with xcode should have openmp. Hmm yours says 4.2.1, can someone with a working Mac install check to see which exact version it is? I wonder if apple upped their support of GCC by 0.0.1...

I took Sam's advice and created a symbolic link from $(YT_DEST)/lib64 to /usr/local/lib/x86_64 but I am still getting errors like this: > > ld: warning: directory not found for option '-L/Users/cperuta/yt-x86_64/lib64/' > > > I've attached the logfile > > Ideas?
Hi, this is the actual cause of failure: gcc -bundle -undefined dynamic_lookup -L/Users/cperuta/yt-x86_64/lib/ -L/Users/cperuta/yt-x86_64/lib64/ -L/Users/cperuta/yt-x86_64/lib/ -L/Users/cperuta/yt-x86_64/lib64/ -L/Users/cperuta/yt-x86_64/lib/ -L/Users/cperuta/yt-x86_64/lib64/ -L/Users/cperuta/yt-x86_64/lib/ -L/Users/cperuta/yt-x86_64/lib64/ build/temp.macosx-10.4-x86_64-2.7/yt/utilities/lib/geometry_utils.o -lm -o yt/utilities/lib/geometry_utils.so -fopenmp
i686-apple-darwin11-gcc-apple-4.2.1: libgomp.spec: No such file or directory i686-apple-darwin11-gcc-apple-4.2.1: libgomp.spec: No such file or directory
Looks like the compiler you're using lacks openmp support. Cheers, Kacper
