[fuse-emulator-devel] [BUG] fuse 1.0.0.1a fails to compile with libpng enabled and libpng version >= 1.5.0beta36

[Marko K. <dr...@gm...>]

Greetings,

As of libpng version 1.5.0beta36, the <png.h> header no longer
includes the <zlib.h> header. Here's a relevant snippet from libpng
ChangeLog (lines 2946-2947):

The standard headers no longer include zlib.h, which is currently only
    required for pngstruct.h and can therefore be internal.

Compilation will fail in screenshot.c with undefined references to
Z_BEST_COMPRESSION and similar macros. Of course, this only happens if
libpng is enabled and if its
version is >= 1.5.0beta36.

The obvious fix would be to simply include <zlib.h> in the
screenshot.c file. Or maybe the include should go in screenshot.h? You
decide.
