Hello Even,<br>
<br>
Thanks for clarifying.<br>
<br>
One more question - Our end-users is trying to use the GDAL shared libs (<i>built with internal GeoTIFF and external libTIFF</i>) in a setup where even they have external GeoTIFF and libTIFF libraries. <br>
<br>
Can I do something to avoid the symbol clashes in Client setup while building the GDAL ?</div>

<p>John,</p>

</p>
<p>yes I believe this should work (although probably not much tested).</p>
<p><br>
</p>
<p>The reverse is explicitly forbidden though (from frmts/gtiff/CMakeLists.txt):</p>

Hi<br>
<br>
Is this allowed if I use GDAL Internal Geotiff and external libtiff library while building GDAL? What all things I need to take care.<br>
Will there be any symbol clashes etc which I need to handle as well?<br>
