<pre><a href="https://libcxx.llvm.org/docs/BuildingLibcxx.html">https://libcxx.llvm.org/docs/BuildingLibcxx.html</a> has a section that starts out:
<span class="quote">> It is sometimes beneficial to build separately from the full LLVM build.
> An out-of-tree build would look like this:</span >
And that no longer works.
If I do this (on Mac OS)
$ cmake -G Ninja -DLLVM_PATH=$LLVM/llvm -DLIBCXX_CXX_ABI=libcxxabi
-DLIBCXX_CXX_ABI_INCLUDE_PATHS=/usr/include $LIBCXX
that works, but then
$ ninja
$ ninja check-libcxx
"ninja: error: unknown target 'check-libcxx'"
Also, running individual tests via lit fails as well:
$ $LIT -sv --param "std=c++17" --param
"libcxx_site_config=$LLVM_BUILD/libcxx/test/lit.site.cfg"
--param=enable_warnings=true $LLVM/libcxx/test/std/utilities/time/</pre>
