'ninja install' fails projects="clang;lldb" built with LLDB_BUILD_FRAMEWORK

[WardenGnaw]

I am having issues running ninja install on a framework build of lldb.

I think its because target lldb-python-scripts installs before https://github.com/llvm/llvm-project/blob/master/lldb/source/API/CMakeLists.txt can install.

Steps:

cd ~
git clone https://github.com/llvm/llvm-project.git
cd llvm-project
git checkout release/10.x
mkdir -p ~/buildspace
mkdir -p ~/buildspace/llvm-build
mkdir -p ~/buildspace/llvm-inst

cd ~/buildspace/llvm-build

cmake -DLLVM_ENABLE_PROJECTS="clang;lldb" -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=~/buildspace/llvm-inst/ -DCMAKE_OSX_ARCHITECTURES=x86_64 -DLLDB_RELOCATABLE_PYTHON=1 -DLLDB_INCLUDE_TESTS=OFF -DLLDB_BUILD_FRAMEWORK=1 -GNinja ~/llvm-project/llvm

ninja

ninja install

ninja install fails with: CMake Error: failed to create symbolic link '~/buildspace/llvm-inst/Library/Frameworks/LLDB.framework/Resources': file already exists

Any ideas on how to fix this?

Below are the logs and the relevant generated cmake_install.cmake files for reference:

Having the same problem. Using OS X 10.14.6. Any luck?

[WardenGnaw]

I have a workaround for now:

ninja install # <--- Fails

rm -rf $(Build.StagingDirectory)/buildspace/llvm-inst/Library/Frameworks/LLDB.framework

# Build lldb/sources/API first
cmake -P $(Build.StagingDirectory)/buildspace/llvm-build/tools/lldb/source/API/cmake_install.cmake

ninja install # <--- Succeeded

[ncbidoug]

Thank you!

It worked, but needed cd $(Build.StagingDirectory)/buildspace/llvm-inst before the cmake -P command.
