[gdal-dev] [pdal] Building PDAL using pramsey-config.sh

[Stefan Keller]

Hi PDAL and GDAL list

I'm referring to the error reported above when (still) trying to compile
PDAL with pointcloud support.

What I'm really wondering is why GDAL developpers are calling function
gtCPLRealloc
the same as in GeoTIFF lib but with different declaration?

See
/usr/include/gdal/cpl_port.h:533:89: => ‘void* gtCPLRealloc(void*, size_t)’
and
/usr/include/geotiff/cpl_serv.h:144:20 => ‘void* gtCPLRealloc(void*, int)’

-S.
