So I've been trying to get things working on my end for quite a bit now, but am starting to be at a loss as to what's happening. This is my current situation:
* I need to build a number of delegates for MagickWand to use (libjpeg, libpng, libtiff, etc.), but am focusing on libjpeg for now (just a first step).
* I need to build MagickWand static libraries (libMagickCore-6.Q16.a and libMagickWand-6.Q16.a) and link them against the libjpeg delegate.
* I need to copy over those archives (as well as their header files) to another folder and use them to be linked against other objects (to use MagickWand).
Note that I am able to do all of this with no warnings (that I can see from the output), but, when I run a binary in the other folder (the repo I copy the MagickWand static files over to), it gives me the following error:
Code: Select all
Wrong JPEG library version: library is 90, caller expects 80* ImageMagick-6.8.7-8
* jpeg-8c
I have tried the approach of building libjpeg separately and then copying over the necessary files (libjpeg.a, libjpeg.la as well as all headers in include) and linked against that. I have also tried the approach outlined here by user "magick": viewtopic.php?t=13145 (that is - I used the "--enable-delegate-build" flag and copied the libjpeg folder into the ImageMagick source folder before configuring and building).
I am using CMake to outline the rules of building and making, and I'm using clang for the "CC" environment variable and the "CFLAGS" environment variable is set to "-O3 -g -DNDEBUG". This is what my configure command looks like (after building libjpeg and moving into the ImageMagick source directory named as "jpeg"):
