Is it a problem to run an application compiled with gcc-4.2 on Leopard? I'm mainly concerned that gcc-4.2 on 10.6 might link against too new libraries (especially against libgcc) for targeting 10.5? My application starts on 10.5 when using the 10.5 SDK, but is there something I should take special care of? Is using -shared-libgcc discouraged? The reason I'm asking is that on Linux I could _never_ compile on a newer system than the target system unless going completely static with the runtime, so I'm a bit prejudiced against it. Is it really safe on MacOS? Cheers, Mario -- Dipl. Inf.

Using gcc-4.2 on 10.6 Snow Leopard to target 10.5 Leopard?
by Mario Emmenlauer 04 Oct '09

04 Oct '09

site_archiver(a)lists.apple.com Delivered-To: Darwin-dev(a)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.

It seems to me, though, that that question might be better asked at the ICU site than on this list, since there's no vested interest here in tools to start using ICU, whereas the ICU people are the ones most likely to provide such a tool as part of advocating their library. Well, whoever it is that works on CoreFoundation is probably interested in this kind of thing also. And the Core Text/Cocoa Text people probably are too... Not to mention some of the other framework guys (NSPredicate uses ICU as well). I expect that if they are using ICU formatting, they've probably already got ICU formatting in their code, or it doesn't work because it doesn't have ICU formatting in it. So no converter needed there. 8-) 8-). The only Apple use I can verify is in WebKit, which is an Open Source project. The only Apple mailing list I know that might be appropriate would be the Webkitsdk-dev list, which I would think would not be very ICU-centric. Either way, this is not the list, and the appropriate best place to ask the question would be at: This email sent to dmarkman(a)mac.com This email sent to dmarkman(a)mac.com This email sent to site_archiver(a)lists.apple.com
