install python_pcl

[Demommm]

Hi, I would like to thank the open source code for your excellent work!

But I encountered some issues when using conda install -c sirokujira python_pcl to install the python_pcl library.

The following is the error message： Collecting package metadata (current_repodata.json): done Solving environment: failed with initial frozen solve. Retrying with flexible solve. Solving environment: failed with repodata from current_repodata.json, will retry with next repodata source. UnsatisfiableError: The following specifications were found to be incompatible with each other: Output in format: Requested package -> Available versionsThe following specifications were found to be incompatible with your system:

• feature:/linux-64::__glibc==2.27=0
• python==3.9 -> libgcc-ng[version='>=9.3.0'] -> __glibc[version='>=2.17'] Your installed version is: 2.27

May I ask if anyone has encountered a similar problem and how has it been resolved? Thanks!

Hi, I've encountered the same problem, and it seems something wrong with conda, so I used command to configure the PCL:

sudo apt-get update
sudo apt-get install libpcl-dev
sudo apt-get install libpcl-dev pcl-tool

After that I ran cmake and it works. Hopefully, it helps you.
