How to activate openCamLib after compiling it

[nemesis]

I"m sure you all would love to go over this one more time, but...

So, can someone tell me what I'm missing, or what is going on? My FC info -

OS: Ubuntu 18.04.2 LTS
Word size of OS: 64-bit
Word size of FreeCAD: 64-bit
Version: 0.18.16093 (Git)
Build type: Release
Branch: releases/FreeCAD-0-18
Hash: 690774c0effe4fd7b8d2b5e2fb2b8c8d145e21ce
Python version: 2.7.15rc1
Qt version: 5.9.5
Coin version: 4.0.0a
OCC version: 7.3.0

Check the final depth of the operation.
it is on the top of my stock by default, so need to lower it to make it take the surface correctly in account

I have been through all 3 pages of this thread and have done / tried everything mentioned. Compiled and installed opencamlib

I have not used OCL with FC yet - gotta get my machine going first - so take this with a grain of salt.

Last time I compiled OCL you had to specifically enable building of the python library and at the same time disable build of the C++ library. It can only build one language binding at the time.

Thanks for that tip, went back and did a fresh build following the directions in the above linked post and i came up with one additional file that was installed, others were "up to date".

Code: Select all

/usr/bin/cmake -P cmake_install.cmake
-- Install configuration: ""
-- Installing: /usr/local/lib/python2.7/dist-packages/ocl.so
-- Up-to-date: /usr/local/lib/python2.7/dist-packages
-- Up-to-date: /usr/local/lib/python2.7/dist-packages/procmemory.py
-- Up-to-date: /usr/local/lib/python2.7/dist-packages/camvtk.py
-- Up-to-date: /usr/local/lib/python2.7/dist-packages/STLTools.py
-- Up-to-date: /usr/local/lib/python2.7/dist-packages/pyocl.py

Still no joy with the import OCL command on the python console. Still same error, but I do seem to have 3DSurface dropcutter and waterline working, so...

In noticed that ocl.so gets installed for python 2.7 - is your FC running python 2.7 or 3.x ?

Anyway - if it works now, awesome!

Hi,

Is there a symbolic link libocl.so in the directory /usr/lib/opencamlib/ pointing to the library file? If not create it (see below).

On my system the library is not in the ldconfig path, which is strange, because it works out of the box. Perhaps FreeCAD is looking directly in the directory.
Please try the following:

- create a directory /usr/local/lib/opencamlib
- copy the file libocl.so.11.10.84 into that directory
- create a link inside that directory: ln -s libocl.so.11.10.84 libocl.so

I'm trying, but i get still the error message if a missing OpenCamLib.

The try to import ocl with the python console i get the message

Code: Select all

Traceback (most recent call last):
  File "<input>", line 1, in <module>
ModuleNotFoundError: No module named 'OCL'

like quick61, - but different to him FC dosn't find ocl.

Dosn't "File "<input>", line 1, in <module> ModuleNotFoundError: No module named 'OCL'" say that there should be a module OCL should be in the FreeCAD/mod folder?

Hi Herbert,

C:\Users\User\AppData\Roaming\FreeCAD\Mod

Hi,
is it possible that you try to import opencamlib as: import OCL instead of: import ocl?
kind regards

I did, but get`s the same error..

[quick61]

Would anyone have direct and specific instructions on building ocl for python 3? After the latest update for 0.18.1 and the 0.19 builds, ocl is not found anymore due to the move to py3

Really, this ocl thing should not be this hard.
