Hi,
GTK uses the same libPNG IM uses, but IM includes the libPNG code.
Sometimes they conflict. So this is one of the reasons we changed IM for
the next version. In Linux we are going to always use what's installed on
the system instead of using the latest code. That's whats on SVN.
IUP and CD that are on SVN also follows that rule for zlib and freetype.
So regarding the compilation error, it is related to the libpng header
you have installed on your system. Usually at /usr/include/libpng. Can you
check which version is?
Best,
Scuri

What NetFlow Analyzer can do for you? Monitors network bandwidth and traffic
patterns at an interface-level. Reveals which users, apps, and protocols are
consuming the most bandwidth. Provides multi-vendor support for NetFlow,
J-Flow, sFlow and other flows. Make informed decisions using capacity
planning reports. https://ad.doubleclick.net/ddm/clk/305295220;132659582;e
