Looks to me as if your GD library was not compiled with PNG support (and maybe 
not JPG or GIF support either).  Where did you get your GD library from?  Might 
be time to upgrade or reinstall.

Subject: [mrtg] Issue configuring MRTG

All,
I am getting following error when configuring MRTG. I want to use it to measure 
bandwidth using Nagios.
checking for gdImageGif in -lgd... no
checking for gdImagePng in -lgd... no
checking for gdImagePng_jpg in -lgd... no
checking for gdImagePng_jpg_ft in -lgd... no
checking gd.h usability... yes
checking gd.h presence... yes
checking for gd.h... yes
** Ooops, one of many bad things happened:
a) You don't have the GD library installed. Get it from http://www.boutell.com, 
compile it and use either --with-gd-lib=DIR and --with-gd-inc=DIR to specify 
its location. You might also have to use --with-z-inc, --with-z-lib and 
--with-png-inc, --with-png-lib for gd versions 1.6 and higher. Check config.log 
for more information on the problem.
b) You have the GD library installed, but not the gd.h header file. Download 
the source (see above) and use --with-gd-inc=DIR to specify where the file can 
be found.
c) You have the library and the header file installed, but you also have a 
shared GD library in the same directory. Remove the shared library files and/or 
links (e.g. libgd.so.2.0.0, libgd.so and libgd.so.2). This is especially likely 
if you're using a recent (post 1.8.4) version of GD and didn't configure it 
with --disable-shared.
d) You have gd library installed and also it's headers, but you are missing 
libpng (and headers) or freetype (and headers) (mrtg does not use freetype, but 
if your copy of gd is precompiled against it, you have to install it …
I have verified all the 3 points mentioned above but everything seems to be in 
place.
Please help.
Thanks & Regards,
Sakshi Anand
