Cannot Find Symbol when importing Cloudprocpy about trajopt

[EdsterG]

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]

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:

cmake .. -DBUILD_CLOUDPROC=ON-- Boost version: 1.54.0

Thanks!

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

[JulianYG]

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]

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

[mzwang828]

@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!
