Description Andrey Zholos 2010-11-24 10:40:10 UTC 
The POV-Ray port has a patch to allow it to compile with libpng 1.4.
MegaPOV requires the same patch.

This problem is obscured because sometimes MegaPOV configure can't find
the system's libpng and compiles its own libpng 1.2.8 instead (and also
its own libjpeg and libtiff). This apparently depends on whether Xorg
is installed.

Fix: See patch.

Patch attached with submission follows:
How-To-Repeat: Without Xorg installed, configure says:

checking for library containing png_get_libpng_ver... no
configure: libpng will be built and statically linked to MegaPOV


With Xorg installed, configure says:

checking for library containing png_get_libpng_ver... -lpng
checking png.h usability... yes
checking png.h presence... yes
checking for png.h... yes
checking for libpng version >= 1.2.5... 1.4.3, ok

Later, the build stops with many benign warnings and two errors:

png_pov.cpp:1440: error: 'struct png_info_struct' has no member named 'trans'
png_pov.cpp:1473: error: 'struct png_info_struct' has no member named 'trans'
