JUCE 9 : problem with ZLIB and libjpeg

General JUCE discussion

Hello

It seems that an old problem is coming back :

https://forum.juce.com/t/problem-with-zlib-in-juce-8-0-7/

Now, there is also a problem with libjpeg if the libjpeg is already included in your project.

I think we should probably update the breaking changes doc.

Thanks a lot @t0m

The solution works for ZLIB but for the libjpeg, what is the solution ?

Hello

I think I found the problem.

In juce_graphics_libjpg_1.c, the JUCE_INCLUDE_JPEGLIB_CODE flag does not cover all the code.

The #include “juce_graphics/image_formats/jpglib/jdhuff.c” is not excluded if JUCE_INCLUDE_JPEGLIB_CODE = 0. Thus a link error if your project comes with its own version of libjpeg.

Thus in order to solve my problem, I defined JUCE_INCLUDE_JPEGLIB_CODE = 0 in the Projucer and move the #endif at the end of the file.

Thanks for raising this. We’ve fixed this and flagged the breaking change on the develop branch:
