I'm using Mac OS X 10.6.8 and Xcode 3.2.6. main.log attached.

Hi Ryan,

My bad. I committed the update, as the Port was open maintainer. Interestingly, the bug doesn't arise for Lion, which uses the LLVM GCC compiler. I've attached a patch that should make the problem go away.

The xcodebuild patch patch.

Cc Me!

[ryandesign (Ryan Carsten Schmidt)]

That works for me; committed in r84783, hoping it still works on Lion / llvm / clang.

Replying to royliu@…:

Has it ever been fixed for 10.6.8 and gcc?

the usual cause for this error is trying to link c++ code using the C compiler instead of the C++ compiler.

These symbols are defined in a library that is linked in automatically by the C++ compiler when it calls the linker.
