Dolphin, the GameCube and Wii emulator - Forums

Not sure if this is supposed to go under support or development

OS: Arch Linux, Kernel 4.12.10-1-ARCH
Clang 4.0.1 (5.0.0 and 6.0.0-svn also tested)
Libc++ 4.0.1
Cmake settings:

Code:
cmake -D CMAKE_CXX_FLAGS="-stdlib=libc++" -D CMAKE_C_COMPILER="clang" -D CMAKE_CXX_COMPILER="clang++" -D CMAKE_BUILD_TYPE="Release"

When building dolphin-master using clang and libc++, it will fail at

Pretty sure dolphin requires you to be on clang version 3.8

If that's true, then it isn't documented anywhere obvious.

This appears to be a bug in libc++ or the clang compiler bits/ headers. It's using a function that wasn't defined in the library headers without defining it, nothing to do with dolphin.

I don't think dolphin "required" clang 3.8 - so much as that's the only one it's been tested on.
