I had a working Debian Squeeze to Mac OSX Snow Leopard cross- compilation system working. It's documented here:
http://wiki.freepascal.org/Cross_compiling_OSX_on_Linux Unfortunately the method described on that page is now broken. The problem linking for OSX on a Linux no longer works for me. It produces errors like these: i386-darwin-ld: MacOSX10.6.sdk/usr/lib/libiconv.dylib load command 5 unknown cmd field i386-darwin-ld: MacOSX10.6.sdk/usr/lib/libobjc.dylib load command 7 unknown cmd field i386-darwin-ld: MacOSX10.6.sdk/usr/lib/libc.dylib load command 5 unknown cmd field i386-darwin-ld: MacOSX10.6.sdk/System/Library/Frameworks/Carbon.framework/Carbon load command 4 unknown cmd field i386-darwin-ld: MacOSX10.6.sdk/System/Library/Frameworks/Cocoa.framework/Cocoa load command 4 unknown cmd field i386-darwin-ld: MacOSX10.6.sdk/System/Library/Frameworks/OpenGL.framework/OpenGL load command 5 unknown cmd field i386-darwin-ld: MacOSX10.6.sdk/System/Library/Frameworks/Foundation.framework/Foundation load command 6 unknown cmd field Here's what I'm using: 1) FPC 2.6.2 rc1 (and I've tried 2.6.0 as well). 2) Apple's cctools 809 release suitably patched. 3) A Debian Wheezy Linux host. The cctools-809 source comes from: http://www.opensource.apple.com/tarballs/cctools/cctools-809.tar.gz The patch applied to make it buildable for Linux is: https://github.com/mingwandroid/xchain/blob/master/patches/cctools-809-nondarwin.patch plus a few tweaks of my own to fix some build bugs. It's built against MacOSX10.6.sdk (I've tried MacOSX10.5.sdk too) for 32 bit (-m32) builds (64 bit is not supported). FPC, FCL, LCL et al are all built against the same SDK. Compilation works just but linking fails as shown above. I've tried various combination of compilation switches but nothing seems to allow the link to succeed. Does anyone have a clue why this might be failing? I seems like I'm on the brink of success if only I can work out why these errors are occurring. The most obvious thought is that not all objects were built against the same revision of the SDK but I can confirm they are. The missing command codes are (from MacOSX10.6.sdk/usr/include/mach-o/loader.h): #define LC_THREAD 0x4 /* thread */ #define LC_UNIXTHREAD 0x5 /* unix thread (includes a stack) */ #define LC_LOADFVMLIB 0x6 /* load a specified fixed VM shared library */ #define LC_IDFVMLIB 0x7 /* fixed VM shared library identification */ I will give up on this if no one has any ideas and the wiki needs to be updated to report that cross-compilation from Linux to Mac is no longer possible but I'm willing to give it some more work based on pointers anyone can suggest. Failing that I will revert to a native Mac system but I'd really like to have cross-compilation working if possible. Any suggestions?
