These two tests copy the clang binary into the test tree and assume it will run from a new location. This is incompatible with relative rpath values, which is what you typically get in a dylib developer build. Disable these tests if shared libraries are involved. Another way to make these tests work would be to update the loader search path environment variables, but it is difficult to do that portably.

// General tests that the header search paths for libc++ detected by the driver

|
// and passed to CC1 are correct on Darwin platforms. This test copies the clang
|
|
// binary, which won't work if it uses any dynamic libraries (BUILD_SHARED_LIBS,
|
|
// LLVM_LINK_LLVM_DYLIB, or CLANG_LINK_CLANG_DYLIB).

// On Darwin, libc++ can be installed in one of the following places:
|
|
// 1. Alongside the compiler in <install>/include/c++/v1
|
|
// 2. Alongside the compiler in <clang-executable-folder>/../include/c++/v1
|
|
// 3. In a SDK (or a custom sysroot) in <sysroot>/usr/include/c++/v1
|
|
|
|
// The build folders do not have an `include/c++/v1`; create a new
|
|
// local folder hierarchy that meets this requirement.
|
|
// Note: this might not work with weird RPATH configurations.
