site_archiver@lists.apple.com Delivered-To: Darwin-dev@lists.apple.com User-agent: Mozilla-Thunderbird 2.0.0.22 (X11/20090707) Hi, we would like to move our development to 10.6 Snow Leopard, and use gcc-4.2, while keeping target MacOS 10.5 Leopard. Is it a problem to run an application compiled with gcc-4.2 on Leopard? I'm thinking especially about gcc's libraries, and flags like -shared-libgcc (we compile not from XCode, but from the command line). I am aware of setting export MACOSX_DEPLOYMENT_TARGET="10.5" CFLAGS+="-mmacosx-version-min=10.5" CFLAGS+="-isysroot /Developer/SDKs/MacOSX10.5.sdk" but will that help against gcc linking its own (newer) libraries? Whats the recommended settings for targeting 10.5 from Snow Leopards command line? Or would you rather advise me to stick with Leopard as the development OS? Thanks for any insight, Mario Emmenlauer _______________________________________________ Do not post admin requests to the list. They will be ignored.
