Build errors on Ubuntu 16.04 using PCL-1.8.0 stable version

[s0r2637]

Hi,

I am a Ubuntu 16.04 user with PCL-1.8.0 installed. When I run the setup.py file Python-PCL binding, I get the following error. It says that it cannot find pcl/point_cloud.h. I am wondering where is it searching for it. I appreciate your help at the earliest.

Package pcl_2d-1.8 was not found in the pkg-config search path. Perhaps you should add the directory containing pcl_2d-1.8.pc' to the PKG_CONFIG_PATH environment variable Package 'pcl_2d-1.8', required by 'pcl_features-1.8', not found Package pcl_2d-1.8 was not found in the pkg-config search path.

Hi, i ran into the same issue and it appears to be because of pcl_2d-1.8. It has been partially removed from pcl1.8 (commit c6338b25d5165bb2483403234cc1c61394b897eb) but some of its symbols are still used by pcl_features. To compile python-pcl, you can either remove pcl_2d from your pkgconfig/pcl_features-1.8.pc or recompile libpcl from github after reverting the commit in fault. Anyway, the fact that pkg-config did not stop after "Package pcl_2d-1.8 was not found in the pkg-config search path." is misleading.

Excuse me. How did you make it compatible with PCL1.8 ? It shows that :

setup.py: error: cannot find PCL, tried
    pkg-config pcl_common-1.7
    pkg-config pcl_common-1.6
    pkg-config pcl_common

When i tried to install .

After modifying line 10 in /usr/local/lib/pkgconfig/pcl_features-1.8.pc as @albat92 said to

Requires: pcl_common-1.8 pcl_search-1.8 pcl_kdtree-1.8 pcl_octree-1.8 pcl_filters-1.8 #pcl_2d-1.8 pcl_2d-1.8 error disappeared

@zcy1065670505 Since it was not fulfill my needs, I decided to use PCL library provided in C++ for finishing my project. You can check the documentation in this link .
