Installing wrk on OSX

• Go to app store and install OSX developer tools, i.e., Xcode.
• Ensure that you have the xcode command line tools installed.

xcode-select --install 

• Install brew see instructions at: http://brew.sh/ (Very simple process)
• Install openssl latest lib this will put lib files and *.h files on your OSX box

brew install openssl

• If you do not have git then install it

brew install git

• Ensure that the search order for openssl and brew is ahead of system bin
• You can do the last step by putting this in your ~/.profile

export PATH=/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin

• Note that brew installs packages to /usr/local/bin
• Download the source code

 git clone https://github.com/wg/wrk.git
 cd wrk

• Now you need to edit the Makefile and add a few things

Change the first two lines from:

CFLAGS  := -std=c99 -Wall -O2 -D_REENTRANT 
LIBS    := -lpthread -lm -lcrypto -lssl 

To:

CFLAGS  := -std=c99 -Wall -O2 -D_REENTRANT -I/usr/local/opt/openssl/include
LIBS    := -lpthread -lm -lcrypto -lssl -L/usr/local/opt/openssl/lib

• Note the last step just adds the libs and headers to the openssl that brew installed.
• Now run make

  make

• Expected output
