When I try and download the libjpeg-turbo libraries for cygwin64, it all comes apart. The "libjpeg-turbo" package is source only, and when I install "libjpeg-devel" and link against it with "-ljpeg", all the jpeg function calls are undefined.

Hi Bill,
could you show your link instruction ?

Have you a small test case ?

FYI the turbo devel package is : libturbojpeg-devel
