Not sure if the issue comes from GDAL. Looks a bit more like a bad interaction between libgeotiff "simplified" CPL library ( http://trac.osgeo.org/geotiff/browser/trunk/libgeotiff/cpl_serv.h ) when mixed with GDAL headers. Perhaps libgeotiff should be updated to use size_t instead of int ? If doable, the best thing would be for PDAL to avoid including in the same .cpp file both geotiff/cpl_serv.h and gdal/cpl_port.h. Or cheating by #define CPL_SERV_H_INCLUDED before including libgeotiff headers. This reminds me of a similar discussion : http://trac.osgeo.org/gdal/ticket/4374 Even > > > > 2013/10/29 Heng Zhi Feng ([email protected]) <[email protected]> > > > Hello, > > > > We are having issues building PDAL on Ubuntu 13.10, following the guide > > on *[1].* > > > > > > > > Initially, PDAL successfully compiles with using the “cmake –G “Unix > > Makefiles” ../” command.
