[GRASS-user] how to install libLAS on MAC for use in GRASS and maybe R?

[Jan Verbesselt]

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.

Best regards,
Jan

They don't use my frameworks, so if you are using my GRASS binaries you will be duplicating all those libraries (GDAL, Geotiff and their dependencies).  Boost could be trouble, it looks like liblas uses boost libraries (boost is by default a header-only library).
