Page History

This page documents the requirements and special instructions for building Traffic Server on Mac OS X macOS.

To build Traffic Server, you will need to retrieve yourself a copy of PCRE, libtool, and automake. You can get it yourself from the source or elsewhere like macports or Homebrew.

Traffic Server only builds with clang on Mac OS X. macOS We do not support building with gcc on this platform. You will need to install the latest version of Xcode.

Building Traffic Server with Homebrew

...

After you have PCRE development libraries installed on your system, you should get the Traffic Server code with git.

$ git clone https://github.com/apache/trafficserver.git

...

$ make
$ sudo make install

Generates a compilation database for clang tooling with Bear

JSON Compilation Database ( compile_commands.json ) is used by clang based tools.   For autotools based project (like Traffic Server), Bear is a tool that generates a compilation database.

On macOS or Fedora there is a know issue that bear generates empty compilation database because of SIP. Below is instruction to avoid the issue. Assuming above instruction is done. (automake autoconf libtool are already installed).

In short, all building tool chain should not be under certain directories which is protected by SIP. 

$ cp /bin/sh /usr/loca/bin/
$ brew install bear llvm make
$ which clang clang++ gmake
/usr/local/opt/llvm/bin/clang
/usr/local/opt/llvm/bin/clang++
/usr/local/bin/gmake
$ CONFIG_SHELL=/usr/local/bin/sh CC=clang CXX=clang++ ./configure --ADD-OPTIONS-YOU-WANT
$ bear gmake
