From 630235bd9e049a8da47c05b1b82790272e22c834 Mon Sep 17 00:00:00 2001 From: Sylvain Joubert Date: Fri, 11 Aug 2017 10:46:29 +0200 Subject: Clang: Find version-suffixed LLVM/Clang binutils Debian renames all LLVM/Clang binaries with a version suffix to allow multiple versions to be installed at the same time. While there is a version-agnostic package that adds a symlink to provide the standard binary names, if only the versioned packages are installed, binaries must be found as `binary-x.y`. In any case, using the same version of the `binutils` as the compiler seems better. --- Modules/Compiler/Clang-FindBinUtils.cmake | 8 ++++++++ 1 file changed, 8 insertions(+) diff --git a/Modules/Compiler/Clang-FindBinUtils.cmake b/Modules/Compiler/Clang-FindBinUtils.cmake index e2822a1..b852660 100644 --- a/Modules/Compiler/Clang-FindBinUtils.cmake +++ b/Modules/Compiler/Clang-FindBinUtils.cmake @@ -2,6 +2,12 @@ if(NOT DEFINED _CMAKE_PROCESSING_LANGUAGE OR _CMAKE_PROCESSING_LANGUAGE STREQUAL message(FATAL_ERROR "Internal error: _CMAKE_PROCESSING_LANGUAGE is not set") endif() +# Debian: +# * /usr/bin/llvm-ar-4.0 +# * /usr/bin/llvm-ranlib-4.0 +string(REGEX MATCH "^([0-9]+\\.[0-9]+)" __version_x_y + "${CMAKE_${_CMAKE_PROCESSING_LANGUAGE}_COMPILER_VERSION}") + # Try to find tools in the same directory as Clang itself get_filename_component(__clang_hint_1 "${CMAKE_${_CMAKE_PROCESSING_LANGUAGE}_COMPILER}" REALPATH) get_filename_component(__clang_hint_1 "${__clang_hint_1}" DIRECTORY) @@ -12,6 +18,7 @@ set(__clang_hints ${__clang_hint_1} ${__clang_hint_2}) # http://manpages.ubuntu.com/manpages/precise/en/man1/llvm-ar.1.html find_program(CMAKE_${_CMAKE_PROCESSING_LANGUAGE}_COMPILER_AR NAMES + "${_CMAKE_TOOLCHAIN_PREFIX}llvm-ar-${__version_x_y}" "${_CMAKE_TOOLCHAIN_PREFIX}llvm-ar" HINTS ${__clang_hints} DOC "LLVM archiver" @@ -20,6 +27,7 @@ mark_as_advanced(CMAKE_${_CMAKE_PROCESSING_LANGUAGE}_COMPILER_AR) # http://manpages.ubuntu.com/manpages/precise/en/man1/llvm-ranlib.1.html find_program(CMAKE_${_CMAKE_PROCESSING_LANGUAGE}_COMPILER_RANLIB NAMES + "${_CMAKE_TOOLCHAIN_PREFIX}llvm-ranlib-${__version_x_y}" "${_CMAKE_TOOLCHAIN_PREFIX}llvm-ranlib" HINTS ${__clang_hints} DOC "Generate index for LLVM archive" -- cgit v0.12
