[cfe-dev] [libc++] Running tests from cmake?

[David Chisnall]

Thanks to many helpful off-list emails from Howard and others, I now have a working port of libc++, running on top of libcxxrt on FreeBSD, giving us (I think) a completely GNU-free C++ stack.  For the moment, we actually have more tests passing on FreeBSD than Darwin, although I'm sure that won't last for long.  

Many thanks to everyone who helped make this possible,

David

There doesn't seem to be any documentation on building with cmake, but I presumed that make check would work after the build.  It definitely does something, but it dies with:

Tests that end in *.pass.cpp are expected to pass.   Tests that end in *.fail.cpp are expected to fail.  You can run testit from any subdirectory under test/ to run a subset of the suite.
