From 6bfcd697851219f35688299c32e7068fad50c6f5 Mon Sep 17 00:00:00 2001 From: Khem Raj Date: Thu, 19 May 2016 23:11:45 -0700 Subject: [PATCH 2/5] Simplify cross-compilation. Don't use native-compiled llvm-config. Note: AddLLVM.cmake does not expose the LLVM source directory. So if you want to run the test suite, you need to either: 1) set LLVM_MAIN_SRC_DIR explicitly (to find lit.py) 2) change AddLLVM.cmake to point to an installed 'lit'. 3) add_subdirectory(compiler-rt/test) from clang instead of compiler-rt. https://us.codeaurora.org/patches/quic/llvm/50683/compiler-rt-cross-compilation.patch Signed-off-by: Greg Fitzgerald Signed-off-by: Khem Raj --- CMakeLists.txt | 10 +++++++++- 1 file changed, 9 insertions(+), 1 deletion(-) diff --git a/CMakeLists.txt b/CMakeLists.txt index 4b953b212..571aee7ea 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -62,7 +62,15 @@ set(COMPILER_RT_BAREMETAL_BUILD OFF CACHE BOOLEAN "Build for a bare-metal target.") if (COMPILER_RT_STANDALONE_BUILD) - load_llvm_config() + find_package(LLVM REQUIRED) + list(APPEND CMAKE_MODULE_PATH "${LLVM_CMAKE_DIR}") + + # Variables that AddLLVM.cmake depends on (included by AddCompilerRT) + set(LLVM_TOOLS_BINARY_DIR "${LLVM_INSTALL_PREFIX}/bin") + set(LLVM_LIBRARY_DIR "${LLVM_INSTALL_PREFIX}/lib") + + set(LLVM_LIBRARY_OUTPUT_INTDIR + ${CMAKE_BINARY_DIR}/${CMAKE_CFG_INTDIR}/lib${LLVM_LIBDIR_SUFFIX}) # Find Python interpreter. set(Python_ADDITIONAL_VERSIONS 2.7 2.6 2.5) -- 2.16.1
