testdisk @6.13 - Build fails using clang

[larry.velazquez@…]

Building testdisk fails for me when clang is used as the compiler:

:info:build Undefined symbols for architecture x86_64:

However, sudo port install testdisk configure.compiler=llvm-gcc-4.2 seems to make no difference; it still uses clang as the compiler. Manually adding "configure.compiler llvm-gcc-4.2" to the Portfile does fix the problem for me. I'm not sure why this is.

Mac OS X 10.7.2 (11C74), Xcode 4.2.1 (4D502), MacPorts 2.0.3.

Never mind, sudo port install testdisk configure.compiler=llvm-gcc-4.2 just worked for me. Not sure what happened before.

Did you clean between the normal install and when you manually set the compiler?

Replying to snc@…:

I think I neglected to do so when I wrote the ticket. So now testdisk installs fine with llvm-gcc, but not with clang.

Thanks, we're now avoiding clang: r90097.
