cmake @3.0.0_3 - Linking fails with OSX 10.4 and Xcode 2.5

[lars.haulin@…]

The path to the dependencies of every dynamic library gets prefixed with "/Developer/SDKs/MacOSX10.4u.sdk". Excerpt from main.log (full log attached)

:info:build Linking CXX executable ../bin/ccmake
:info:build /usr/bin/ld: warning can't open dynamic library: /Developer/SDKs/MacOSX10.4u.sdk/opt/local/lib/liblzo2.2.dylib referenced from: /opt/local/lib/libarchive.dylib (checking for undefined symbols may be affected) (No such file or directory, errno = 2)

The library libarchive.dylib seems to be correct though:

I bypassed the error with "sudo ln -s /Developer/SDKs/MacOSX10.4u.sdk/opt /opt/" , but I guess there are better solutions...

Yes, this is a well-known bug in the linker on Tiger PowerPC when making universal binaries.

Do you have the apple-gcc42 port installed with the bootstrap variant? If so, reinstall it without the bootstrap variant. This will install the ld64 port, which provides a newer version of the linker that IIRC does not have this bug anymore.

[ryandesign (Ryan Carsten Schmidt)]

The symlink that you created is also a viable workaround for the problem.
