Install MSYS

MSYS is a collection of GNU utilities such as bash, make, gawk and grep to allow building of applications and programs which depend on traditionally UNIX tools to be present. It is intended to supplement MinGW and the deficiencies of the cmd shell.

If you have installed mingw, select the install directory when the post-install cmd window pops up. I have installed Qt with mingw, so I select that folder.

Make libjpeg

open an MSYS shell, switch to the directory of jpeg-9a, then input ./configure
