How to activate openCamLib after compiling it

[Erich Schulz]

done

[chrisb]

Thanks!

[sgrogan]

I made a small update.

[Erich Schulz]

so...

I have successfully compiled OCL... (using the readme https://github.com/aewallin/opencamlib per https://www.freecadweb.org/wiki/OpenCamLib)

and have a functioning version of freecad daily...

but I am getting `OpenCamLib is not working!` (twice AND in red!!!) when I open the path workbench.

any clues???

OS: Ubuntu 18.04.2 LTS (ubuntu:GNOME/ubuntu)
Word size of OS: 64-bit
Word size of FreeCAD: 64-bit
Version: 0.19.

OCC version: 7.3.0

I think you need to set this in CMake

Code: Select all

cmake -DBUILD_PY_LIB=ON -DUSE_PY_3=OFF ../src

See also here: https://forum.freecadweb.org/viewtopic. ... 20#p311763
This is part of zach's GSoC so I think it's OK to ping him in that topic. He had an upstream ocl pull request merged that helps this.
You can turn off or leave on the cxx libs and doc's (FreeCAD doesn't need them).

ok... i've been banging at the keyboard randomly....

I've added the following to my bash history

Code: Select all

cmake -DBUILD_PY_LIB=ON -DUSE_PY_3=OFF ../src
sudo make install
cmake -DBUILD_PY_LIB=ON ../src
sudo make install
history | tail

at this point I seem to have several likely looking files based on the end of the last install:

but still I get "OpenCamLib is not working!"

[Erich Schulz]

I am getting some warnings during the build about boost - but the process seems to roll on - is that the problem or is this a path issue??

[Russ4262]

Evening, Sir.
Was just looking through your posts here.

My observation is that your nightly build is for Python 3.6 and your recent successful build of OCL is for Python 2.7 based upon quoted code snippet above.

You will need to attempt an OCL build with Python 3.6 - probably a CMake flag or similar in the source/build files.
OR
You will need to install a nightly build based on Python 2.7 that should be compatible with your successful OCL build for Python 2.7.

Disclaimer: I don't have a Linux machine, so perhaps I don't have the whole picture.

Best wishes,
Russ

Your FreeCAD Python version is 3.6.8 and your building OCL for 2.7. Not going to work. Please let me know if you get OCL to build with Python 3.6.8. on 18.04.2, and how you did it. Haven't figured that one out yet....

thanks Russ - I thought I had both a 3.x and 2 version - but like you I'm a bit out of my depth :-/
