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

The message tells you the problem - MRTG cannot compile, because you do not
have a working GD library.  The most likely reason I think (since you
clearly have gd.h installed) is that it is a too old version that does not
support PNG, GIF or JPG.

Try doing this -

1.       Upgrade your GD library to the latest available version, and make
sure you have the dev package as well if necessary.  In Redhat Linux, this
means installing the 'gd' and 'gd-devel' packages; in Debian or Ubuntu, try
to install 'libgd-dev' (it has a lot of dependencies).

2.       If this does not work, install from source.  Download from
boutell.com the GD library source, and configure and install for your
system.  You will also need to get libpng and libfreetype if you do not have
them installed already.

** 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 ...
