Overview wrk should build on most UNIX-like operating systems and architectures that have GNU make and are supported by LuaJIT and OpenSSL. Some systems may require additional CFLAGS or LDFLAGS, see the top of the Makefile for examples In many cases simply running `make` (often `gmake` on *BSD) will do the trick. Dependencies wrk requires LuaJIT and OpenSSL and is distributed with appropriate versions that will be unpacked and built as necessary. If you are building wrk packages for an OS distribution or otherwise prefer to use system versions of dependencies you may specify their location when invoking make with one or more of: WITH_LUAJIT WITH_OPENSSL For example to use the system version of both libraries on Linux: make WITH_LUAJIT=/usr WITH_OPENSSL=/usr Or to use the Homebrew version of OpenSSL on Mac OS X: make WITH_OPENSSL=/usr/local/opt/openssl
