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
