<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">You probably installed zlib (the runtime library) but not zlib-dev (the development compile-time library and headers).<br>
<div><br>
In many distros, the <i>libname </i>and <i>libname</i>-dev packages are separate. For compilation purposes, when it says you need
<i>libname</i>, you should install the <i>libname</i>-dev package.<br>
<br>
As soon as one lib is missing, then this will start a chain of dominoes and youll get lots of errors from the compile/install process. Deal with the missing things in the order they are reported.<br>

<p class="MsoNormal">Hello,</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">I am a beginner Unix user and very new to compiling as I am not a programmer at all. I am running Ubuntu 12.04, I have been following the instructions for installation in mrtg-unix-guide.txt for mrtg-2.17.3</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">. I run through the process with zlib with no problem or errors.. When I execute:</p>
<p class="MsoNormal">sudo env CFLAGS=”-03 –fPIC” sudo ./configure –prefix=$INSTALL_DIR</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">The last line states: configure: error: zlib not installed.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">If I ignore that and continue on to the last step before moving to the mrtg directory and doing ./configure –prefix=/usr/local/mrtg-2, I get the error that **Ooops, one of many bad things happened which lists four possibilities dealing
with GD libraries, header files, shared directories, or missing libpng.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">However, I believe I’ve been pretty meticulous in following the instructions, installing the latest available versions of zlib, gd, and libpng.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Any advice or direction would be very much appreciated.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Thanks,</p>
