What does LIBCXX_LIBCPPABI_VERSION get set to when building libcxx?
I'm working on a build script to build LLVM 7.0 release tarballs from sources. Most of my attempts to build libcxx and libcxxabi have failed. Someone suggested I should set LIBCXX_LIBCPPABI_VERSION.
I have not located documentation on the CMake option. I found a mailing list message that sets it to "2", but it is in the context of OS X. I also found a Ubuntu patch that sets it to empty "".
What should the value of LIBCXX_LIBCPPABI_VERSION be when building libcxx and libcxxabi from sources?

Here are the details of configuration required to build libcxxabi and libcxx:
To build:
- Check out libcxxabi into llvm/projects
- cd llvm
- mkdir build && cd build
- cmake .. # on linux you may need to prefix with CC=clang CXX=clang++
- make
To do a standalone build:
- Check out the libcxx source tree.
- cd libcxxabi
- mkdir build && cd build
- cmake -DLIBCXXABI_LIBCXX_PATH=path/to/libcxx .. # on linux you may
need -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ - make
By default CMake uses llvm-config to locate the required LLVM sources. If CMake cannot find llvm-config then you must configure CMake using either of the following options.
-DLLVM_CONFIG_PATH=path/to/llvm-config
-DLLVM_PATH=path/to/llvm-source-root
To run the tests:
- make check-cxxabi
Note: in a standalone build, the system's libc++ will be used for tests. If the system's libc++ was statically linked against libc++abi (or linked against a different ABI library), this may interfere with test results.

Here are the details of configuration required to build libcxxabi and libcxx:
To build:
- Check out libcxxabi into llvm/projects
- cd llvm
- mkdir build && cd build
- cmake .. # on linux you may need to prefix with CC=clang CXX=clang++
- make
To do a standalone build:
- Check out the libcxx source tree.
- cd libcxxabi
- mkdir build && cd build
- cmake -DLIBCXXABI_LIBCXX_PATH=path/to/libcxx .. # on linux you may
need -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ - make
By default CMake uses llvm-config to locate the required LLVM sources. If CMake cannot find llvm-config then you must configure CMake using either of the following options.
-DLLVM_CONFIG_PATH=path/to/llvm-config
-DLLVM_PATH=path/to/llvm-source-root
To run the tests:
- make check-cxxabi
Note: in a standalone build, the system's libc++ will be used for tests. If the system's libc++ was statically linked against libc++abi (or linked against a different ABI library), this may interfere with test results.
