Today, Xcode started failing to link a project that has worked in the
past. I see lots of these in the build transcript:
symbol _acosl used from dynamic library /Developer/SDKs/
MacOSX10.3.9.sdk/usr/lib/gcc/powerpc-apple-darwin8/4.0.1/libstdc+
+.dylib(single module) not from earlier dynamic library /usr/lib/
libSystem.B.dylib(ld64.o)
symbol _tanl used from dynamic library /Developer/SDKs/
MacOSX10.3.9.sdk/usr/lib/gcc/powerpc-apple-darwin8/4.0.1/libstdc+
+.dylib(single module) not from earlier dynamic library /usr/lib/
libSystem.B.dylib(ld64.o)
The failed link is the ppc build of a Universal Binary. The ppc build
uses the 10.3.9.sdk and deployment target is 10.3. Those errors look
to me like one thing using libstdc++.dylib from the 10.3.9.sdk and
another thing is using libSystem.B.dylib from /usr/lib. I don't
understand what that means. The main project and all subprojects use
the same sdk and deployment target settings, and all libraries and
frameworks were added from the /usr/lib or /System/Library/
Frameworks/ directories, NOT from the .sdk directories. I just double-
checked these things and didn't notice anything using the wrong lib/
framework. Any ideas? The Debug config builds fine (but probably
doesn't complain because ZeroLink is on).
