Best Answer
As of 2018, the Homebrew Versions repository ('tap') is out of service.
The stock Homebrew llvm package still doesn't include clang/clang++, by default. Thus, it isn't part of the prebuilt ('bottled') package.
One can build it via:
And then use it via e.g.:
But this
--with-toolchain
induced build takes a very long time and is thus unsuitable in a continuous integration (CI) environment.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XCode (which is available in CI environments like Travis-CI, Version 9 is the default, 10 available, too) isn't that outdated anymore as it used to be (Apple uses an fantasy version scheme for clang that doesn't match upstream clang version numbers but cmake detects e.g. for AppleClang 9.1.0.9020039 the version 4.0.1). Thus, it is sufficient to build C++11/C++14 software with common dependencies like Boost (e.g. version 1.67).
2016 State of the Art
The
llvm
package in Homebrew doesn't includeclang++
, by default. When installing it, you have to add--with-clang
to the command line (e.g.brew install --with-clang llvm
). The extra--with-clang
yields a full package compile because there is only one prebuild ('bottled')llvm
package available (withoutclang++
). In addition to that: thellvm
package is relatively old - currently it has llvm 3.6 - where 3.7 was released 6 months ago.Thus, to get a bottled
clang++
3.7 you have to install the llvm package from Homebrew Versions:It is then available under:
