Hi all,
I may have triggered this discussion about Mac gcc/gfortran problems
by my mail to Dave yesterday...
Thanks for the quick response.
YES, gcc/gfortran from macports solves all issues (after cleaning up
the mess left by all other attempts, or better, starting from
scratch). On OS 10.6.7, I succeeded using the gcc and gfortran 4.4.6
versions below:
gcc
Using built-in specs.
Target: x86_64-apple-darwin10
Configured with: ../gcc-4.4.6/configure --prefix=/opt/local
--build=x86_64-apple-darwin10
--enable-languages=c,c++,objc,obj-c++,java,fortran
--libdir=/opt/local/lib/gcc44 --includedir=/opt/local/include/gcc44
--infodir=/opt/local/share/info --mandir=/opt/local/share/man
--with-local-prefix=/opt/local --with-system-zlib --disable-nls
--program-suffix=-mp-4.4
--with-gxx-include-dir=/opt/local/include/gcc44/c++/
--with-gmp=/opt/local --with-mpfr=/opt/local --enable-stage1-checking
--enable-fully-dynamic-string
Thread model: posix
gcc version 4.4.6 (GCC)
and
gfortran
Using built-in specs.
Target: x86_64-apple-darwin10
Configured with: ../gcc-4.4.6/configure --prefix=/opt/local

Any attempts with pre-built gnu compilers for Mac failed in my hands
(various binaries from
http://r.research.att.com/tools/ or
http://hpc.sourceforge.net/). I have sometimes used such binaries
successfully for other projects, but it seems to be a lottery.
My advice: make this clear in the documentation, without offending the
people who spend time to create binaries and offer them to the
community, of course...:-). And maybe add a short note on how to
ensure that the macports compilers are actually used (gcc_select for
those who have a mess of compilers like me for now...)
