Import Area Error With Ubuntu 11.10 about heekscnc-old

[aewallin]

ubuntu 11.10 should have boost 1.46.1. I would suggest using that and not something older (like 1.42)

That kind of ImportError is a boost-python error where a C++ function/method exists but no python-wrapping has been provided. When troubleshooting you can just go into a python-shell and type "import area", no need to run heekscnc and the G0 button.

I can confirm this issue on Ubuntu 11.10 with gcc 4.6.1, boost 1.46.1, and Python 2.7.2+
I get the same error:
anders@anders-i7:~/libarea/.libs$ python
Python 2.7.2+ (default, Oct 4 2011, 20:06:09)
[GCC 4.6.1] on linux2
Type "help", "copyright", "credits" or "license" for more information.

import area.so
Traceback (most recent call last):
File "", line 1, in
ImportError: ./area.so: undefined symbol: _ZNK5boost6python7objects21py_function_impl_base9max_arityEv

This looks like a linking-problem with boost-python and/or python2.7. Googling for the error-message gives various solutions mostly related to linking issues.

Rather than figuring out what is wrong with the Makefile I have solved this by using cmake:
Heeks/libarea#2

OK - I copied an area.so build to my /usr/lib/heekscnc/ directory and I can use heekscad/cnc again. I still need the tags, though.

Thank you...
