I've finally gotten back to trying to build Ipopt and the Matlab interface on my Mac. I've been able to build Ipopt successfully, but I'm having trouble with the MEX build. Here is my setup ...
OS X 10.6.8 Snow Leopard
Ipopt-3.10.1
gcc -v : gcc version 4.2.1 (Apple Inc. build 5666) (dot 3)
gfortran -v : gcc version 4.2.1 (Apple Inc. build 5664)
(from http://r.research.att.com/tools/)
Matlab R2011b (7.13)
Using ...
../configure --with-blas="-framework vecLib" \
--with-lapack="-framework vecLib" F77=gfortran \
FFLAGS="-fexceptions -m64 -fbackslash" \
CFLAGS="-fno-common -no-cpp-precomp -arch x86_64 -m64" \
CXXFLAGS="-fno-common -no-cpp-precomp -fexceptions -arch x86_64 -m64" \
-disable-shared CC=gcc-4.0 CXX=g++-4.0
I added the following line to ~/.matlab/R2011b/mexopts.sh (from a Mar 9, 2010 posting by Peter)
LDFLAGS="$LDFLAGS -framework vecLib"
In Ipopt-3.10.1/build/Ipopt/contrib/MatlabInterface/src/Makefile
MATLAB_HOME = /Applications/-math/MATLAB_R2011b.app/
MEXSUFFIX = mexmaci64
When I run 'make' for the MatlabInterface, I get the following:
$ make

mex: -framework not a valid option.
Usage:
MEX [option1 ... optionN] sourcefile1 [... sourcefileN]
[objectfile1 ... objectfileN] [libraryfile1 ... libraryfileN]
Use the -help option for more information, or consult the MATLAB External Interfaces Guide.
make: *** [ipopt.mexmaci64] Error 1
So if I manually attempt to run the same call to mex, with all of the '-framework vecLib' entries removed (why are there 4 of them anyway)? Then I get the following error ...
ld: library not found for -lgfortranbegin
collect2: ld returned 1 exit status
mex: link of ' "ipopt.mexmaci64"' failed.
But I do have ...
/usr/lib/gcc/i686-apple-darwin10/4.2.1/libgfortranbegin.a
/usr/lib/gcc/i686-apple-darwin10/4.2.1/libgfortranbegin.la
/usr/lib/gcc/i686-apple-darwin10/4.2.1/x86_64/libgfortranbegin.a
/usr/lib/gcc/i686-apple-darwin10/4.2.1/x86_64/libgfortranbegin.la
I'm guessing all I need is a nudge in the right direction. Any help is appreciated. By the way, once I am successful with this build, I hope to try it on OS X 10.7 Lion as well.
Thanks,
