Compiling Liblas

Question

I am trying to install the library libLAS. I’m working with Microsoft Visual Studio 2010 , windows 7 and Cmake 2.8.10.2 . So far I’ve Installed Boost 1.51 and I followed this tutorial: http://www.liblas.org/compilation.html#using-visual-studio-9-2008-on-windows

After quite a few problem with cmake, I created the .sln, which I am now trying to compile. In particular, I'm trying to build the project 'liblas'. I receive 37 errors, all like this one:

Error   1   error LNK2001: unresolved external symbol "class boost::system::error_category const & __cdecl boost::system::generic_category(void)" (?generic_category@system@boost@@YAAEBVerror_category@12@XZ)  C:\temp\libLAS\buildout\src\writer.cpp.obj

Edited to add other errors:

That error message says that you're not correctly linking to the `boost_system` library. — us2012, Mar 18 '13 at 14:19
Show us all of the errors. My guess is that you haven't specified the library directory in your linker path. — metal, Mar 18 '13 at 14:21
I put 'C:/Boost/boost_1_51/lib' in 'Additional Library Dependency' in the Linker. I also filled the 'Additional Dependencies' part. — Yellaine, Mar 18 '13 at 14:38
What libraries did you put in the additional dependencies? It seems that you're missing boost_system. — metal, Mar 18 '13 at 14:48
kernel32.lib user32.lib gdi32.lib winspool.lib shell32.lib ole32.lib oleaut32.lib uuid.lib comdlg32.lib advapi32.lib ..\bin\Debug\liblas.lib c:\OSGeo4W\lib\libtiff_i.lib c:\OSGeo4W\lib\geotiff_i.lib c:\OSGeo4W\lib\gdal_i.lib c:\OSGeo4W\lib\laszip.lib libboost_program_options-vc100-mt-gd-1_51.lib libboost_thread-vc100-mt-gd-1_51.lib libboost_system-vc100-mt-gd-1_51.lib — Yellaine, Mar 18 '13 at 14:53
I used another version of boost that I compiled myself, and things seems to work better now. Not sure why though... — Yellaine, Mar 18 '13 at 15:58
The list of additional dependency libs appear to be Debug ones, while your error message relates to a Release build. Did you correctly add the Release Boost.System lib to the Additional Dependencies for Release Configuration? — Fraser, Mar 18 '13 at 22:08
Did you try [this](http://stackoverflow.com/questions/3808775/cmake-doesnt-find-boost)? — Olha Puzhay, Mar 21 '13 at 10:26

BlueGo can build libLAS for you: https://bitbucket.org/Vertexwahn/bluego

You can build it on Windows using VS2017 the following way:

set dest=C:\thirdparty\vs2017\x64
set cmake_command=cmake
set boost_root=C:/thirdparty/vs2017/x64/boost_1_65_0
if NOT [%1]==[] set dest=%~1
if NOT [%2]==[] set cmake_command="%~2"
if NOT [%3]==[] set boost_root=%~3
if [%1]==["--boost-root"] set boost_root=%~2
wget.exe --no-check-certificate https://github.com/libLAS/libLAS-1.6/archive/master.zip -O%cd%\master.zip
7za.exe x %cd%\master.zip -o%dest%
call "C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\VC\Auxiliary\Build\vcvarsall.bat" amd64
%cmake_command% -DBUILD_STATIC_LIBS=ON -DBOOST_ROOT=%boost_root% -G"Visual Studio 15 2017 Win64" -H%dest%\libLAS-1.6-master -B%dest%\libLAS-1.6-master\build
del %cd%\master.zip
C:
cd %dest%\libLAS-1.6-master\build
%cmake_command% --build . --config Debug --target liblas
%cmake_command% --build . --config Release --target liblas
%cmake_command% --build . --config RelWithDebInfo --target liblas
%cmake_command% --build . --config Debug --target liblas_c
%cmake_command% --build . --config Release --target liblas_c
%cmake_command% --build . --config RelWithDebInfo --target liblas_c

The link is not working. Do you have any github repository ? — J4cK, Sep 25 '17 at 12:17
