To be able to link the libraries to the MEX files, I had to compile GMP and MPFR using the following configure: ../configure CFLAGS="-m32" CPPFLAGS="-m32" CXXFLAGS="-m32" LDFLAGS="-m32" ABI=32 Then, when compiling the MEX file provide the absolute path to the library and also use the -read_only_relocs suppress switch when compiling the MEX file: mex LDFLAGS="\$LDFLAGS -read_only_relocs suppress" -I/usr/local/include T_Zeta.cpp mpreal.cpp /usr/local/lib/libgmp.a /usr/local/lib/libmpfr.a This tweak seems to work to compile the MEX file on Mac OS X 10.6 running Matlab R2010a. To the best of my knowledge, this does not currently work on any other platform or for any other libraries. |
