@micwoj92 Replacing zlib-ng with zlib worked, but during the update, I was asked to reinstall it (which I declined). If I have to switch between them to update the package, it's going to get annoying quickly...

@cskin Editing PKGBUILD didn't work.

@NY152 You can relax the test by adding the following to the end of the prepare function in PKGBUILD: 'sed -i 's/--strict/--relaxed/g' tests/pngtest-all'.

This is due to using zlib-ng-compat. If you use zlib then it works.

Works here. This is not compilation that failed, but test suite.
In fail message it says to check test-suite.log, there will be more information.

Compilation failed.

Hey the package fails to compile for me complaining about failing tests. With alot about comparing png files and failing

Files ./pngtest.png and pngout.png are different Was ./pngtest.png written with the same maximum IDAT chunk size (8192 bytes), filtering heuristic (libpng default), compression level (zlib default), and zlib version (1.3.1.zlib-ng)?

FAIL libpng FAILS test Default limits: width_max = 1000000 height_max = 1000000 cache_max = 1000 malloc_max = 8000000 ===============FAIL --strict ./pngtest.png ====================

Ahoj,

to be compatible with software that is built from source using cmake, can you please install the following files which are actually installed by official libpng package?:

/usr/lib/cmake/libpng/PNGCheckLibconf.cmake
/usr/lib/cmake/libpng/PNGConfig.cmake
/usr/lib/cmake/libpng/PNGGenConfig.cmake
/usr/lib/cmake/libpng/PNGTest.cmake

Regards and thanks for the package!

There are now APNG patches all the way up to upstream (1.6.43). Also, would you consider adding libpng16.so to "provides"? That's what the libpng package has got, and some packages pin their dependencies to that for some reason (e.g. Leptonica and Electron 28 complain when I try to install this instead of vanilla libpng).

Thanks for double checking that! I just fixed the URL to avoid confusion.
