[gdal-dev] Building GDAL against custom libtiff

[Juan Pedro Pérez Alcántara]

Hi,

I'm having from quiet some time now an issue when building GDAL against an
external TIFF library. For sure is a very silly thing but I'm missing
something important nonetheless. So long, I ended up always compiling with
--with-libtiff=internal and have a perfectly functional installation, but
I'm just curious about this.

The things goes as follows: I installed tiff-4.0.3.tar.gz from osgeo.org,
then I try to configure the GDAL build with --with-libtiff=/usr/local/,
where I installed the libtiff, and it compiles. But somehow, when executing
gdalinfo against a TIFF, I get the following:

Warning 1: libtiff version mismatch : You're linking against libtiff 3.X,
but GDAL has been compiled against libtiff >= 4.0.0

And when I ldd gdalinfo, I get:

 libtiff.so.4 => /usr/lib/i386-linux-gnu/libtiff.so.4 (0xb6482000)
 libtiff.so.5 => /usr/local/lib/libtiff.so.5 (0xb640e000)

and I'm at a loss, it seems that is trying to link to the system library
instead the custom installed. Any insight on this will be most welcomed.
Many thanks in advance.
