Struggling with a PGO build of clang -- llvm-profdata was built without zlib support?
...by hand, so I went for that. Here are my steps: * Built a release version of LLVM/Clang/LLD/compiler-rt on version 9.0.0-rc3 * Built an instrumented clang with the following config: cmake -G Ninja ../llvm \ -DLLVM_ENABLE_PROJECTS='clang;compiler-rt' \ -DLLVM_TARGETS_TO_BUILD=X86 \ -DCMAKE_EXPORT_COMPILE_COMMANDS=ON \ -DCMAKE_CXX_COMPILER=/path/to/release_build/bin/clang++ \ -DCMAKE_C_COMPILER=/path/to/release_build/bin/clang \ -DLLVM_USE_LINKER=/path/to/release_build/bin/ld.lld \ -DLLVM_CCACHE_BUILD=ON \ -DLLVM_BUILD_INSTRUMENTED=IR \ -DLLVM_BUILD_RUNTIME=No \ -DLLVM_ENABLE_ZLIB=1 \ -DCMAK...

Problems building LLVMHello, spaces in path
I recently had a problem creating LLVMHello. I used this CMake file #!/bin/sh # clangcmake.sh cmake -G "Eclipse CDT4 - Unix Makefiles" -DLLVM_TARGETS_TO_BUILD="X86" -DCMAKE_EXPORT_COMPILE_COMMANDS=ON -DCMAKE_BUILD_TYPE="Debug" -DCMAKE_ECLIPSE_VERSION=4.5 -DCMAKE_CXX_COMPILER=clang++ -DCMAKE_C_COMPILER=clang ../llvm then I ran make LLVMHello and the build failed on an error about LLVMHello.export The problem turned out to be that the parent directory path had a space in one...
