Hi Tiangang,
I updated SPDLib to use LASlib in the latest version, see this pull
request for more details and justification:
https://bitbucket.org/petebunting/spdlib/pull-requests/1. As part of
this the code was also updated for GDAL 2.
To compile the latest version of SPDLib you need GDAL 2 or later and
LAStools from https://github.com/LAStools/LAStools. The makefile for
LAStools doesn't include an install command so you will need to manually
copy the library and header files or pass their location to CMake.
To get a version for SPDLib which works with LASlib you need to need to
checkout the version tagged as 'Version_3_2'. This requires GDAL <= 1.11
and libLAS version 1.7, the code wasn't updated to work with libLAS 1.8.
Hope this helps,
Dan

Dear Pete and Dan,
Thank you very much for your prompt reply. Yesterday, I succeeded to
compile the stable version of spdlib (20130504) by reverting the gdal
and liblas to older versions. I would appreciate if I can get more
instructions about laslib compilation and installation. At the same
time, I will try to work with conda.
Regards,
Tiangang

Dear Tiangang,
We have moved SPDLib away from using LibLAS
(http://www.liblas.org) to using laslib (i.e., from lastools;
https://github.com/LAStools/LAStools
<https://github.com/LAStools/LAStools>) as it supports LAS 1.3
with waveforms.
Dan Clewley (cc’d), compete led this work so he might be able to
provide advice on the best way to compile laslib.
Alternatively, we make binary versions available via conda. If you
install miniconda (http://conda.pydata.org/miniconda.html
<http://conda.pydata.org/miniconda.html>) and the run:
conda install -c conda-forge -c rios spdlib
Then it will install the latest version of SPDLib.
Many thanks,
Pete

Dear Dr. Bunting,
My name is Tiangang from CESBIO laboratory of Toulouse. I have
several questions related to the SPDlib installation, and I hope
you could help me.
2 years ago, I was using the SPDlib to process our simulated
LiDAR data. It was working fine. Recently, I tried to reinstall
SPDlib on my new computer using the latest commit from
hg clone https://bitbucket.org/petebunting/spdlib
<https://bitbucket.org/petebunting/spdlib> spdlib
The installation gives me several missing functions referring to
several functions and includes files from LAStools
(https://rapidlasso.com/lastools/
<https://rapidlasso.com/lastools/>), or maybe libLAS.
For example, the compilation error shows:
In file included from
/home/ctpp/GIT/spdlib/include/spd/SPDIOFactory.h:43:0,
from
/home/ctpp/GIT/spdlib/src/spd/SPDIOFactory.cpp:24:
/home/ctpp/GIT/spdlib/include/spd/SPDLASFileImporter.h:33:25:
fatal error: lasreader.hpp: No such file or directory
#include <lasreader.hpp>
^
compilation terminated.
make[2]: *** [src/CMakeFiles/spd.dir/spd/SPDIOFactory.cpp.o] Error 1
make[1]: *** [src/CMakeFiles/spd.dir/all] Error 2
make: *** [all] Error 2
The lasreader.hpp has already been removed from libLAS 1.7.0, and
the latest version of libLAS is 1.8.1.
I can imagine that SPDlib might need a specific version of libLAS
to compile in the latest version. However, I can not find any
instructions on how the installation of configuration of LAStools
for successful compilation of SPDlib. For libLAS, I think several
functions changes from the latest version of the library. Could
you let me know what version of libLAS are you using, or any
instructions to install LAStools?
I would also appreciate if you can suggest on the versions of all
the dependencies of spdlib, including:
CGAL
gdal
gmp
gsl
hdf5
laszip
libLAS
mpfr
proj
qt
xerces
zlib
