Hi ..
I installed APACHE 1.3.27, GD 2.0.11 and PHP 4.3.1 on solaris 2.6
, but I got a fatal error on function imagepng().
Fatal error: Call to undefined function: imagepng() in
/www/htdocs/png.php on line 8
How do i get imagepng() to work properly?
You can see the details below:

So this clearly isn't any bug in PHP. Users should always
make sure they're linking with same libraries in this kind
of cases.

I experienced a similar thing with PHP-4.2.1 + pdflib-4.0.2 on Linux
(glibc-2.2.3). However, recompiling pdflib with: "--with-pnglib
--with-zlib" (and then rebuilding PHP) solved the problem.
My backtrace from before recompiling pdflib was a bit different, I'm
including it here in case it might be of interest:

I'm experiencing the same problem on FreeBSD 4.5 with PHP 4.2.1,
libpdf's internal support for PNG conflicts with PHP linking against
libpng. The two libpng versions differ from libpdf to PHP.
Maybe the people from libpdf could add some configure options to allow
the external libpng to be grabbed, but for now the --with-libpng does
not accept a path as argument, so compilation fails.
In our hosting company, the support for libpdf is suspended until the
bug is fixed.

I am having a similar problem, if you notice in the backtrace, it
references /usr/lib/libpng.so.3 on my system this is soft-linked to
libpng.so.5, and if I remove --with-pdflib from my configure line, it
seems to link against the correct library and not segfault, but
--with-pdflib it reverts to the version 3 library and segfaults when I
try to create from PNG in the GD routines
