build issues

[Rampantsen]

Operating System and version: Ubuntu 20.04 PCL Version: latest version I'm getting the following error message while trying to install PCL

[ 34%] Building CXX object filters/CMakeFiles/pcl_filters.dir/src/local_maximum.cpp.o [ 34%] Building CXX object filters/CMakeFiles/pcl_filters.dir/src/model_outlier_removal.cpp.o [ 34%] Linking CXX shared library ../lib/libpcl_filters.so [ 34%] Built target pcl_filters [ 34%] Linking CXX shared library ../lib/libpcl_surface.so [ 34%] Built target pcl_surface make: *** [Makefile:152：all] 错误 2

This is part of the error message. We need more information (specifically the actual error)

[Rampantsen]

When I try to execute the order “make -j8", it stopped at 34% and say make: *** [Makefile:152：all] 错误 2

And what does the following passage mean?

[kunaltyagi]

You don't have OpenNI2 library but have requested PCL to build features related to it. If you don't need those features (most likely), please consider switching them off using cmake <PCL source directory> -DWITH_OPENNI2:=OFF

thanks, the issue has solved .But I meet new problems When I try to execute the order “make -j8", it stopped [ 15%] Building CXX object surface/CMakeFiles/pcl_surface.dir/src/processing.cpp.o [ 15%]

Please use discord for issues not in the core library. The community can help figure out how to best go ahead.

For now, I'd recommend using make -j2 (will be slower, but uses less RAM in case that's slower), but it could be a useless recommendation given the lack of info (no visible error)

[Rampantsen]

Thanks for your help. I am really appreciate.
