libjpeg-turbo static
Posted: Wed Mar 02, 2016 9:31 am
Has anyone here ever successfully used the static lib of libjpeg-turbo ?
I wanted to try it to see if it decodes jpeg much faster or not.
On both OSX and Linux I could use the pre-build static lib without much problems but on Windows 10 I get linker errors I don't know how to solve.
The unresolved external symbols are __ms_vsnprintf and _putenv .
Example code
