Cannot Find Symbol when importing Cloudprocpy #19

Closed JulianYG closed 5 years ago

JulianYG commented 6 years ago

Hi,

When I add the command line option to build cloudprocpy as well, it builds the cloudprocpy, but when I import the library from python, I got following error:

File "", line 1, in ImportError: /home/cvgl_ros/trajopt/build/lib/cloudprocpy.so: undefined symbol: _ZN9cloudproc12medianFilterIN3pcl8PointXYZEEENS1_10PointCloudIT_E3PtrENS5_8ConstPtrEif

I'm not sure which other lib.so file it is looking for that has wrong version or something. Any one has idea on this? Thanks!

I haven't compiled with cloudprocpy however it's hard to diagnose the problem with so little information. What system are you compiling on? What version of python are you using? Can you copy/paste the output from cmake?

JulianYG commented 6 years ago

I'm using ubuntu 14.04, and python 2.7.6. I tried to run cmake with BUILD_CLOUDPROC option on, and after that the make was successful. I then added the trajopt/build/lib and trajopt/ into .bashrc, but when I import that line I got the error. The output from cmake is:

Do you have PCL installed? If so what version is installed?

JulianYG commented 6 years ago

We are using PCL 1.7. Thanks!

Hi Julian,

Did you solve this problem by any chance? I'm having the exactly same issue when I'm importing the cloudprocpy library. Thanks!

JulianYG commented 5 years ago

@mzwang828 I haven't solved it. Let me know if you do!

mzwang828 commented 5 years ago

@JulianYG Yes, I found a solution. Please check this repo: https://github.com/erictzeng/trajopt You can either use this version or just replace the original cloudproc.cpp and cloudproc.hpp files. I replaced the two files and now it works.

@mzwang828 Thank you so much!
