Hi William, thanks for your advice and great website! I will try to compile liblas via cmake for mac osx. I have downloaded and installed cmake-2.8.3 and now I downloaded the boost package (boostI-jam-3.1.18-1-macosxx86_64.tgz). Following the http://www.boost.org/doc/libs/1_45_0/more/getting_started/unix-variants.html I just need to unzip on the right location.
Which location would you recommend? Will boost install cause potential problems? Should I do something different than described here http://liblas.org/compilation.html#optional-libraries to configure the optional libraries (gdal and geotiff installed before the grass install via your website)? All tips are welcome. Having the liblas library options for grass and R would be great as I am working with terrestrial lidar data (las 1.1 and 1.2) and these files are quite large.
