[EMBOSS] libpng problems on Solaris 8, png.h version versus png.c version

[David.Bauer at SCHERING.DE]

Hi David,

a had similar trouble with this on Solaris.
The best way to get a clean rebuild is to rerun the configure.
Watch for the folowing lines in the configure output:
-----------------------------------------------------------------------------

checking if png driver is wanted... yes
checking for inflateEnd in -lz... yes
checking for png_destroy_read_struct in -lpng... yes
checking for gdImageCreateFromPng in -lgd... yes
PNG libraries found
-----------------------------------------------------------------------------

Unless you don't get "PNG libraries found" here, you are in trouble ;-)
Most often this is caused by the search path for dynamic libraries. On
Solaris you may have somwhere in /opt some older version of libgd.
You get than a "no" for "gdImageCreateFromPng".
If you don't want (or can't) change the libs in system location you can
create the complete set of z,gd,png in an alternative location and use the
option
"--with-pngdriver=DIR"
to point configure to this place. But this has to be the complete
installation containing also the .h files and not just the libraries.

Hope this helps,
David.
