Then, you will find clang++ on /usr/local/opt/llvm/bin/clang++. If you need Python to find bindings for this keg-only formula, run:Įcho /usr/local/opt/llvm/lib/python2.7/site-packages > /usr/local/lib/python2.7/site-packages/llvm.pth Own software and it requires this formula, you'll need to add to your Generally there are no consequences of this for you. OS X already provides this software and installing another version in This formula is keg-only, which means it was not symlinked into /usr/local. LLVM executables are installed in /usr/local/opt/llvm/bin.Įxtra tools are installed in /usr/local/opt/llvm/share/llvm. => cmake -G Unix Makefiles /private/tmp/llvm20160211-42310-16fdrbw/llvm-3.6.2.src -DCMAKE_C_FLAGS_RELEASE=-DNDEBUG -DCMAKE_CXX_FLAGS_RELEAS => Installing dependencies for llvm: cmake You have to install it with -with-clang option: $ brew install -with-clang llvm LDFLAGS="$LDFLAGS -L/usr/local/opt/llvm37/lib/llvm-3.7/lib" The formula also notes: To link to libc++, something like the following is required:ĬXXFLAGS="$CXXFLAGS -nostdinc++ -I/usr/local/opt/llvm37/lib/llvm-3.7/include/c++/v1" Boost productivity, streamline tasks, and innovate with ease Discover the game-changing potential of Homebrew Xcode, a package manager that empowers developers to enhance their macOS-based app development. ![]() It is then available under: /usr/local/bin/clang++-3.7 Unleash the power of Homebrew Xcode to customize and optimize your app development environment. Thus, to get a bottled clang++ 3.7 you have to install the llvm package from Homebrew Versions: $ brew tap homebrew/versions In addition to that: the llvm package is relatively old - currently it has llvm 3.6 - where 3.7 was released 6 months ago. The extra -with-clang yields a full package compile because there is only one prebuild ('bottled') llvm package available (without clang++). When installing it, you have to add -with-clang to the command line (e.g. The llvm package in Homebrew doesn't include clang++, by default. Thus, it is sufficient to build C++11/C++14 software with common dependencies like Boost (e.g. However, the clang that comes with recent XCode (which is available in CI environments like Travis-CI, Version 9 is the default, 10 available, too) isn't that outdated anymore as it used to be (Apple uses an fantasy version scheme for clang that doesn't match upstream clang version numbers but cmake detects e.g. LDFLAGS='-L/usr/local/opt/llvm/lib -Wl,-rpath,/usr/local/opt/llvm/lib' \īut this -with-toolchain induced build takes a very long time and is thus unsuitable in a continuous integration (CI) environment. One can build it via: brew install -with-toolchain llvmĪnd then use it via e.g.: $ PATH="/usr/local/opt/llvm/bin:$PATH" \ ![]() Thus, it isn't part of the prebuilt ('bottled') package. The stock Homebrew llvm package still doesn't include clang/clang++, by default. As of 2018, the Homebrew Versions repository ('tap') is out of service.
