[Liblas-devel] libLAS SRS Reprojection Support and Compiling From Source

[Dan Bellinski]

Hi Howard,

My goal in using libLAS is to reproject a LAS 1.2 file onto another
SRS (State plane to Lat/Long). Further, I am using it in a Java
program so I would like to run the conversion from the command line so
it can run within my Java code. Will this be possible with either the
GeoTIFF linking or GDAL linking support? If this will work, could you
offer any insight to the below compile error I am receiving?

I am currently trying to compile libLAS from the current source (I
have obtained a clone from the Mercury server). I am compiling it
against GDAL (built from source) and GEOTiff (obtained from OSGeo4W).
I am using VC 2008, running the nmake /f makefile.vc command and am
running into the error:

c:\osgeo4w\include\geo_config.h(6) : warning C4005: 'STDC_HEADERS' :

Stop.
NMAKE : fatal error U1077: '"c:\Program Files\Microsoft Visual Studio

I believe I have the proper libraries linked in nmake.opt for GDAL and
GeoTIFF. Have you seen this error before?

Thanks a lot for your help!
