<div>Hi, that tutorial is quite old, and qgis has changed quite a bit since then...</div><div><br></div>most probably your gdal.h is not in the include search path.  <div><br></div><div>Did you instal libgdal-dev with your package manager? </div>
<div><br></div><div>If not you need to set CPLUS_INCLUDE_PATH and possibly C_INCLUDE_PATH to the include dir where you installed gdal.</div><div><br></div><div>cheers</div><div>Etienne<br><div class="gmail_quote"><br></div>

</div>What version of linux are you on?<br>
<br>
In order to compile you need to have the -dev version of various<br>
packages (aka the source code of those packages). So you're probably<br>
missing libgdal-dev<br>
<br>
On Debian/Ubuntu the following will auto install what's needed for you:<br>
sudo apt-get build-dep qgis<br>
<br>
Though I thought the build would fail if you were missing those.<br>
<br>
Enjoy,<br>
Alex<br>
