@m-schuetz laszip_dll.h file seems to be only for Windows environment. Is it possible to replace those logic to use only "include/laszip/*.hpp" files ? Also, "cmake/FindLASzip.cmake" file seems not to be pushed to the Git repository.

I missed the following latest installation documentj, and there was no problem about Mac OSX build. https://github.com/potree/PotreeConverter/blob/master/README.md

Hi, I'm kind of new so please excuse me if I'm not supposed to comment my question here. I'm trying to install PotreeConverter, but I could not find any Unix executable file after running the cmake command :

cmake -DCMAKE_BUILD_TYPE=Release -DLASZIP_INCLUDE_DIRS=~/MyDirectory/dev/lastools/master/LASzip/dll -DLASZIP_LIBRARY=~/MyDirectory/dev/lastools/master/LASzip/build/src/liblaszip.dylib ..

I modified the command to MyDirectory. And I put liblaszip.dylib since I could not find the liblaszip.so file. I'm sorry if this is really dumb to do but I have tried both lines and the results seem to be the same. I supposed the output in the terminal meant it was built. But then I could not find any Unix executable file in my master folder to run PotreeConverter. The output of cmake is below

-- Boost version: 1.58.0 -- Found the following Boost libraries: -- system -- thread -- filesystem -- program_options -- regex -- Boost_INCLUDE_DIRS: /usr/local/include -- Boost_LIBRARY_DIRS: /usr/local/lib -- Configuring done -- Generating done -- Build files have been written to: /MyDirectory/dev/PotreeConverter/master/build

Do you know what is the problem? I really need to set PotreeConverter up Thank you very much!

Hi,

cmake generates the make build files for you so after calling cmake, you also have to call make Not sure about dylib, probably the mac equivalent of so files.

Hope this helps.

Thanks a lot for the respond, potree! It helped. I got it

hey @githmith , how did you figure out your issue? I'm running into the same problem, and I've tried replacing the .so file ext with .dylib, then running make after with no luck. Thanks!!

[thanhmvu]

Hi @rchav, my problem before were that I had the directories wrong and I did not call make after running cmake. So I found my relative directories for the dll folder and the liblaszip.dylib, corrected the paths and ran make. If these do not work, could you specify the error message that cmake prints out so that me or other people can help you?
