# there is a glitch with the libjpeg-turbo-1.3.1 configure file that makes it difficult to compile on Mac, so I tried regular libjpeg:
curl -LO http://www.ijg.org/files/jpegsrc.v8c.tar.gz
tar zxvf jpegsrc.v8c.tar.gz
cd jpeg-8c/
CC=../afl-gcc ./configure
make
# error: C compiler cannot create executables
# if the above command worked to build an instrumented djpeg, then this should work
cd ..
./afl-fuzz -i in_dir -o out_dir ./jpeg-8c/djpeg
Install homebrew if you don't have it already, then
brew install gcc
CC=gcc-4.9 make clean all
However, we then get stuck as djpeg is a shell file (and .libs/djpeg exits with error 5) and I've got a bit distracted to continue. Good luck!
