Created attachment 95355 [details] patch to use the current API WebCore::writeOutput() in WebCore/platform/image-encoders/skia/PNGImageEncoder.cpp tries to access (struct *png_struct)->io_ptr which is deprecated in libpng-1.4 and removed in 1.5. The new way is to use png_get_io_ptr(). Attached is a patch that uses this function.

fyi, from the libpng manual: The png_get_io_ptr() function has been present since libpng-0.88, has never changed, and is unaffected by conditional compilation macros. so this patch is backwards compatible with pretty much every distribution that's newer than 1999.

Commit queue can't land the patch with this line. You should just remove it, as it's obvious why no test is needed. > WebCore/ChangeLog:11 > + * platform/image-encoders/skia/PNGImageEncoder.cpp: > + (WebCore::writeOutput): Use the new API As you explained in Bugzilla, the API is not new.
