So I'm not sure it's an option. Anyways I could > get past the point in my original email by not forcing libstdcxx to be > linked statically. OK. Looking at: https://discussions.apple.com/thread/2252567?threadID=2252567 It seems static linking is not supported on MacOS-X. Sigh... And for the specific issue at hand, as Titus pointed out: http://lists.apple.com/archives/unix-porting/2006/Aug/msg00012.html we have a static version libtsdc++-static that we can link against. > Like Titus, I'm not really sure why we should > consider linking gcc statically against libstcxx (and at this point I > can say I chose that option with no knowledge about it, just because > it sounded nice :). The idea is to be able to move the toolchain from one host to another without too much hassles... While the C library is pretty standard and backward-compatible, the libstdc++ is very tightly coupled to the compiler. But if you do not need that, then you can disable this option. Regards, Yann E.
