@sintaxi @hph if you're on OS X and have homebrew installed, it's as simple as brew install wrk. Otherwise a simple make && make install should work after cloning the repo.

Thanks for the issue report! I'll keep this in mind for future updates of the README or an INSTALL file.

On CentOS i had to install openssl-devel, and also got the following error:

>sudo make
...
LUAJIT scripts/wrk.lua
luajit: cannot open /scripts/wrk.lua: No such file or directory
make: *** [obj/bytecode.o] Error 1

On CentOS I had the prereqs installed and Make seemed to work, however:

[root@ip wrk]# make install
make: *** No rule to make target `install'.  Stop.

@BrianHutchison I got the same popup, seems no install target written in Makefile

[vanquang9387]

I got same "make: *** No rule to make target `install'. Stop." when "make install"
