'jpeglib.h' file not found

I am trying to read a jpg image in c++. I downloaded libjpg as it was suggested at this link https://www.opengl.org/wiki/Image_Libraries and installed it. Although when I include the library Xcode fails building saying 'jpeglib.h' file not found

#include <jpeglib.h>

I can see the header in /usr/local/include/ directory so I can't understand why Xcode won't see it.

OS and Software details:

OSX 10.11 (El Capitan)

Xcode 7.0.1

Solution

  • OK, it looks like you just need to:

    1. Add /usr/local/include to the Header Search Path (turn recursive off). This still looks relevant.
    2. Link explicitly against /usr/local/lib/libjpeg.a from within Link binary with libraries (reference). This will link in the static library, meaning there is no need to distribute the JPEG dynamic library with your app.
