It may work fine for 5.0. There's no guarantee that later on 5.*'s libc.so ABI will diverge even more from 4.*'s libc.so and break it again. > > or set up a proper cross-env to target the platform where the library > > is targettted > > This is what I guess we'll have to do. The 4.* -> 5.* link issue is exactly the same issue as the gcc 2.95 -> 3.0 -> 3.2 C++ ABI one. At least they changed the name mangling so it was physically impossible to let old libs link with new libs, instead of letting people think their program linked okay, only to have it mysteriously fail later. Maybe we should have a freebsd-4-devel package that provides a gcc/g++ 2.95 that will link with 4.* crt0 and libc, etc? -- Dan Nelson dnelson@allantgroup.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
