Unable to install on jetson-tx2

[cmpute]

Have you ever installed PCL (the C++ library) on the machine? Unfortunately PyPCL now is not standalone library, it depends on the C++ version of PCL

Hi,
I get the same error even with PCL installed. Does it need to be referenced somehow?
Do you have any advice?
Thanks in advance

You mean error showing that cannot find PCLConfig.cmake? I guess this is due to that the path for PCL is not setup correctly. Did you install pcl using apt?

I was eventually able to get this installed using PCL1.8

I had to patch PyPCL to respect my header location:

@bfouts-kindred I didn't find the corresponding codes in my source. Where does pypcl_build.py come from? Currently the location of PCL is determined by CMake modules, so as long as your PCL installation is able to be discovered by CMake, then it should be fine to build

The old version of pypcl has been deprecated, so this issue is going to be closed.
