compiling laszip on OSX (El Capitan)

[Carlos Grohmann]

Hi, 

I'm trying to compile laszip on OSX. My first attempt was with Homebrew. There is a recipe for it (http://brewformulas.org/Laszip), but the only commands I get with this are "laszippertest" and "laszip-config" (I was expecting "laszip").

Then I downloaded the src file (laszip-2.2.0.tar.gz) and run the usual ./configure, make, make install. Again, no laszip command was installed. So I went to GitHub, but it looks like the devel version needs to be compiled with cmake. Anyway, I ran autoconf.sh (got some errors) and tried to run ./configure (more errors).

Looking at the homebrew formula, I tried "cmake ." and then make, make install. This time I got 

Install the project...

-- Install configuration: ""

-- Installing: /usr/local/lib/liblaszip.6.0.0.dylib

-- Installing: /usr/local/lib/liblaszip.1.dylib

-- Installing: /usr/local/lib/liblaszip.dylib

-- Installing: /usr/local/lib/liblaszip_api.6.0.0.dylib

-- Installing: /usr/local/lib/liblaszip_api.1.dylib

-- Installing: /usr/local/lib/liblaszip_api.dylib

-- Up-to-date: /usr/local/include//laszip/

-- Installing: /usr/local/include//laszip//laszip_api.h

So it looks like this is only installing the library, not any executables. Is that right? If so, how to zip/unzip las files? 

thanks

Carlos,

The LASzip standalone library is just for other applications to provide LAZ support. It does not come with a command line utility to read/write LAZ data. That would require something that could speak LAS.

You can get that through either LASlib, libLAS, or PDAL. The former two have Homebrew recipes.

$ brew install liblas
$ las2las myfile.las myfile.laz

Hope this helps,

Howard

Hello,

the answer that Howard gave covers the three options. Here some more info on the first. I think (or rather hope) that my simple (hand-written & old-school) Makefiles still do the trick on most Linux systems. I know they do on the one I use for testing. Either download LAStools from here

http://lastools.org/download/LAStools.zip

or fork it on github

http://github.com/LAStools/LAStools

and then do the following:

cd LAStools

make

cd bin

ll laszip

The source that is the standalone compressor based upon the LASlib (with LASzip) library is here:
