[llvm-dev] Installing selected subset of LLVM Tools with shared build
Hi all, I have an application that requires a select subset of LLVM tools to be installed into a custom-built sysroot. Until recently, I've been building LLVM statically and everything seemed fine, but recently, due to disk space limits, I have decided to give shared build a try. The problem I encountered, however, is that when I ask `ninja` to only build and install a specific component, its dependencies are being built, but not installed. In particular: cmake $sources_path/llvm \ -G Ninja \ -DBUILD_SHARED_LIBS=On \ -DCMAKE_BUILD_TYPE=Release \ -DCMAKE_INSTALL_PREFIX=$target_path \ -DLLVM_ENABLE_ASSERTIONS=On \ -DLLVM_TARGETS_TO_BUILD=X86 cmake --build $build_dir --target llvm-ar cmake --build $build_dir --target install-llvm-ar This compiles all the required shared libraries, but installs only the llvm-ar executable, which causes: $target_path/bin/llvm-ar --version build-env/sysroot/bin/llvm-ar: error while loading shared libraries: libLLVMX86CodeGen.so.5: cannot open shared object file: No such file or directory Is there a way to force the existing build system to also install dependencies, when using `install-$tool` target? AFAIK, plain `install` builds and installs everything, which would require a manual search through the output directory in order to clean up the unneeded tools. Alternatively, is there an easy way to list the targets required by a specific component in such a way, a proper collection of install targets can be invoked later?
