[regression] WebKit: some images are not loaded

[X512]

This is hrev54212.

WebKit: ​​https://github.com/haiku/webkit/commit/aeb81f69c0b6e210aa5ad0363270ca444ac92bff.

Issue is not present in current WebPositive version.

Test case is avatars on ​https://discuss.haiku-os.org/

Working: ​https://discuss.haiku-os.org/user_avatar/discuss.haiku-os.org/zblace/25/4119_2.png

Not working: ​https://discuss.haiku-os.org/letter_avatar_proxy/v4/letter/l/b487fb/25.png

It seems that WebKit can't load any PNG images including local.

[X512]

Issue is caused by wrong zlib versions. WebKit use libzlib.so instead of libz.so.1. Adding symlink fixes problem.

Strange, how did that happen? Is it a problem with our libpng?

[X512]

Can be caused by ​https://github.com/haikuports/haikuports/issues/4685. Haiku libpng16.so is fine and use correct zlib version. Similar problem occurred in Blender.

[X512]

From cmake log:

-- Found ZLIB: /Haiku/data/packages/webkit/WebKitBuild/Release/lib/libzlib.so (found version "1.2.11")

That is wrong. Best way is to fix ​​https://github.com/haikuports/haikuports/issues/4685.

I created a simple CMake project for testing and did not reproduce this problem.

I also checked the CMakeCache for WebKit in my local build and the paths are correct there as well.

[X512]

As mentioned in that ticket, it may depend on installed packages such as opencollada. Cmake seems to prefer libzlib over libz.

[pulkomandy]

opencollada is not available in chroot when building webkit, so fixing this particular problem will not solve the issue here.

In your cmake log I see that the libzlib.so is in WebKit release directory. So cmake found it there after you had created the link to fix the problem? Where did it find it previously?

[X512]

Where did it find it previously?

/boot/system/lib/libzlib.so from opencollada-1.6.68-1 package.

[pulkomandy]

Duplicate version of zlib removed from opencollada package.
