(Problem also exists with 3.0.16)

I installed gd 1.8.2, libpng 1.0.9, zlib 1.1.3, jpeg 6b, compiled and installed into the default locations.

However, everytime I run PHP configure, it fails to find :


I stumbled across this yesterday when building PHP 3.0.16 and found duplicate symbols that were defined
both in PHP and GD.  Downloading PHP 4.0.0 today, I still find the problem.

My work around was to modify config.h and define explicitly by hand :

#define HAVE_GD_PNG  1
#define HAVE_GD_JPG 1

And modify the Makefile macro APXS_LDFLAGS to add : -ljpeg -lpng

looks like you have parts from an old gd installation 
left over somewhere ???

Confirmed - it happens to me too, on RH 6.1 gd 1.8.1 installation. Configure seems to try and conpiled GD without linking libgpng, libz and a dozen of other libraries that RedHat GD installation needs to be linked.

You may want to try GD 1.8.3 RPMs from - they work for me. I still believe this should be fixed (i.e., one doesn't need to link GD to check if we have libz and libpng).

This should be fixed. If not, please reopen.
