I noticed that gcc 4.4 is required for compilation. I know that Mac likes to tweak gcc. Does this mean that llvm-g++-4.2 is too old? I could install the normal version of gcc4.6 which is the latest in macports. On Sun, Nov 27, 2011 at 4:00 PM, Jesse Berwald <jberwald@gmail.com> wrote:
Thank you. I too have very little experience with Mac's multiple architecture concept. (This would have been done days ago in Linux. argh!) Sadly, the plot thickens. After including the two -arch flags and running configure, the compiler gets tripped up immediately. It appears that multiple architectures are not supports with many compiler options(?):
make all-recursive Making all in src Making all in graph Making all in centrality CXX graph_betweenness.lo llvm-g++-4.2: -E, -S, -save-temps and -M options are not allowed with multiple -arch flags make[4]: *** [graph_betweenness.lo] Error 1 make[3]: *** [all-recursive] Error 1 make[2]: *** [all-recursive] Error 1 make[1]: *** [all-recursive] Error 1 make: *** [all] Error 2

These architecture issues on Mac are mystifying to me. How can something be built for the wrong architecture if I just compiled it for that architecture? sigh... Thanks any help you can provide.
I have very little experience with building stuff with multiple architectures with apple's GCC, but according to the documentation you should pass something like "-arch i386 -arch x86_64" to the compiler to generate "universal" binaries. From the ./configure command you sent in the first email, it did not seem you passed this. Hence you should try something like:
./configure CXXFLAGS="-arch i386 -arch x86_64 -I/opt/local/include" <..your other options..>
I hope it helps.
Cheers, Tiago
