Subject: [mrtg] 1 out of many error messages: checking for gdImageGif in -lgd... no

I am getting following error when configuring MRTG. I want to use it to measure bandwidth using Nagios.

On most platforms, binary packages for MRTG are available wherever your usual repositories of packages are.

In most instances, you don’t need the RATEUP binary at all, because installations at scale generally use RRDTOOL.

But since we don’t know what platform you are running this on, and we don’t know which of the 4 debugging steps listed below you have tried, and we don’t know precisely what your mrtg installation is going to look like, I don’t think anyone can really help you…

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<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 ...
