[LLVMdev] [libcxx] Linking against just-built libcxxabi (original) (raw)

On OS X 10.9.5, I can only get all libcxx tests to pass if I link against the system libcxxabi. If instead, I link against the just-built libcxxabi (using Apple LLVM version 6.0 based on LLVM 3.5), I see the following test failures:

Failing Tests (9): libc++ :: std/language.support/support.dynamic/new.delete/new.delete.array/new_array.pass.cpp libc++ :: std/language.support/support.dynamic/new.delete/new.delete.array/new_array_nothrow.pass.cpp libc++ :: std/language.support/support.dynamic/new.delete/new.delete.single/new.pass.cpp libc++ :: std/language.support/support.dynamic/new.delete/new.delete.single/new_nothrow.pass.cpp libc++ :: std/language.support/support.exception/except.nested/rethrow_nested.pass.cpp libc++ :: std/localization/locales/locale.global.templates/use_facet.pass.cpp libc++ :: std/localization/locales/locale/locale.cons/char_pointer.pass.cpp libc++ :: std/strings/basic.string/string.capacity/max_size.pass.cpp libc++ :: std/thread/thread.threads/thread.thread.class/thread.thread.destr/dtor.pass.cpp

Error messages include:

libc++abi.dylib: terminating libc++abi.dylib: terminating with uncaught exception of type std::bad_cast: std::bad_cast libc++abi.dylib: terminating with uncaught exception of type std::runtime_error: locale constructed with null libc++abi.dylib: terminating with uncaught exception of type std::bad_alloc Assertion failed: (false), function main, file std/language.support/support.dynamic/new.delete/new.delete.array/new_array.pass.cpp, line 50. Assertion failed: (new_handler_called == 1), function main, file std/language.support/support.dynamic/new.delete/new.delete.array/new_array_nothrow.pass.cpp, line 42.

To link against the just-built library, I'm adding the following CMake define:

-DLIBCXX_CXX_ABI_LIBRARY_PATH=../libcxxabi_install/lib

Am I building libcxxabi correctly? All tests in its own test suite pass. Or perhaps is libcxxabi only supported for certain OS X versions?

Thanks, Greg
