Compile on osx with Xcode 2.4.1 =============================== Build a custom expat for Xcode 2.4.1 sdks with the script: scripts/compile-expat-universal.sh Then ./configure.sh osx-ARCH. If you like to build a universal binary use make -C buildfactory osx Cross compile for win32 ======================= cvs -d :ext:$USER@cvs.sf.net:/cvsroot/freepops/ co mingw32_freepops cvs -d :ext:$USER@cvs.sf.net:/cvsroot/freepops/ co packages cvs -d :ext:$USER@cvs.sf.net:/cvsroot/freepops/ co freepops apt-get install mingw32 mingw32-runtime mingw32-binutils apt-get install xpm2wico sysutils nsis bison flex automake-1.7 autoconf cd packages make win The compilation needs a line like this one in your /etc/sudoers: user ALL = NOPASSWD: /usr/bin/dpkg -i mingw32-*, /usr/bin/dpkg -r mingw32-* Where user is your username. But be careful, this is not a really good practice for non-home pc since running dpkg -i is enough to run arbitrary code as root.
