[mesa-users] pgstar won't store files

[Jonathan Stott SJ]

Hi Craig,

I've had the same error (I'm on a Mac, but any OS with shared libraries will do).

The problem is you have multiple copies of the dynamic libpng in your system and you're compiling against one set of headers but linking at runtime against the library from a different version.  In my case, there was a copy (v1.2.x) in /usr/local/lib and a different version (v1.5.x) in /usr/X11/lib.  I deleted the older copy in /usr/local/lib, recompiled the executable because I'm paranoid, and everything has worked fine since.
