Make OTP build w/alternative gcc on MacOS Lion
Requires own build of wxMac for wx to work: $ arch_flags="-arch i386" $ ./configure CFLAGS="$arch_flags" CXXFLAGS="$arch_flags" \ CPPFLAGS="$arch_flags" LDFLAGS="$arch_flags" OBJCFLAGS="$arch_flags" \ OBJCXXFLAGS="$arch_flags" --prefix=/usr/local \ --with-macosx-sdk=/Developer/SDKs/MacOSX10.6.sdk \ --with-macosx-version-min=10.6 --enable-unicode --with-opengl $ make $ sudo make install - and we have macports gcc 4.5 in /opt/local/bin, so we configure and build OTP like this for 32bit (which is required for wx): $ cd $ERL_TOP $ PATH=/usr/local/bin:$PATH CC=/opt/local/bin/gcc-mp-4.5 CXX=/opt/local/bin/g++-mp-4.5 ./configure --enable-m32-build $ MAKEFLAGS="-j6" PATH=/usr/local/bin:$PATH make
