So here is an email chain with the conda-forge maintainers of the LAStools package about liblas in Anaconda which is not liblas, but actually laslib misnamed. This is why there is no liblas-config. Since liblas.dylib is installed with the lastools package in
Anaconda, I asked if they might also create a liblas-config file (not currently installed) so that GRASS can compile against it for LiDAR support
<div class="">
<div class=""><br class="">
</div>
<div class="">The upshot is that LAStools (and laslib, misnamed as liblas) can be installed through Anaconda, but not the packages we know as libLAS. Also, it seems like libLAS is no longer maintained and superseded by LASlib and related tools. I have an email
from William Kyngesburye (copied) from several years ago suggesting that GRASS lidar support could potentially use LASlib instead of liblas. But I don't know what that would involve. </div>

OK. This is good to know. So the file that is named liblas.dylib in the conda package of lastools is in fact laslib?

<p class="">Yes the library file is called the same, but the contents are different. In an early version of this recipe i renamed the files to be clear, but that broke other software....</p>

Indeed. But the anaconda package installs liblas, not laslib.

Thanks for the quick response Dan,

<div class="">I have indeed seen both the open source libLAS code and the LAStools site. The thing is that the Anaconda package installs liblas.dylib into ../lib as well as command line tools in ../bin with the same names as the tools built with the libLAS
code. A couple years ago, a colleague on the GRASS project looked into the (then new) LAStools distribution and thought that it could be a drop in replacement for libLAS code. So I was hoping to try this with the Anaconda build. But we need a liblas-config
to do it. I'm copying a couple colleagues on GRASS who also might be able to help with this.</div>

<p class="">This is the feedstock for <a href="https://github.com/LAStools/LAStools" class="">LAStools</a> and LASlib not <a href="https://github.com/libLAS/libLAS" class="">libLAS</a> which I believe is the library GRASS can be compiled against. The libLAS
website has a page explaining the relationship between the two: <a href="https://www.liblas.org/lastools.html" rel="nofollow" class="">https://www.liblas.org/lastools.html</a>. The two libraries provide similar functionality but aren't compatible.</p>
<p class="">From the libLAS website "As of 2014, libLAS has been almost entirely superceded by Martin Isenburg‘s LASlib library."</p>
<p class="">More specifically this feedstock builds a fork of LAStools (<a href="https://github.com/gillins/LAStools/" class="">https://github.com/gillins/LAStools/</a>) which adds CMake build scrips. The standard LAStools doesn't provide a <code class="">liblas-config</code> file,
we could add one to the fork this is being build against but I think this would only make things between the two libraries more confusing.</p>
<p class="">I'm going to mark this as closed but if I am incorrect and it is LASlib you need please reopen for further discussion.</p>
