Summary: I am doing GSOC2016 for ASCEND, and I will do something on Canvas function.
- Browse my code here: mike:
- Check out my code using svn co http://svn.ascend4.org/branches/mike
Discussion notes of 12 May 2016
To get the canvas GUI running in the trunk code, I used:
john@thunder:~/ascend/trunk2$ ./pygtk/canvas/canvas.py
May 12 to May 22
- Set development environment and play with canvas.
- Find a problem about module 'ascpy' in my branch, which cannot be found in canvas.py.
- But when I run canvas.py of main trunk, module 'ascpy' can be found, but another error is called:
libascend.so.1: cannot open shared object file: No such file or directory
Discussion notes of 23 May 2016
- cannot find module 'ascpy' is because I need to compile by
scons -j4
- find a bug of Adrian's branch, which is, when run the solver, ascend kills the background terminal. Trying different ubuntu system may work.
May 23 to May 29
- Tested Adrian's branch on ubuntu 16.04 LTS. Previous bug doesn't exist (ascend kills the terminal)
- Try to understand Gaphas and libavoid.
- Link 'libavoid' on ASCEND wikin has 404 error.
- When 'scons' ASCEND in Ubuntu16.04, SWIG error comes. sulution here
Discussion notes of 30 May 2016
- When try to run canvas.py, should set PYTHONPATH to
ascend_trunk/trunk/model/johnpye/fprops/python
- For Adrian's version
- canvas.py doesn't work because of
Error: sys.path must be a list of directory names
- Reason: installed python-gaphas uses gtk2. But we require gtk3. Solution:
git checkout gtk3 git pull
- However, after canvas.py pops up, TypeError: Couldn't find conversion for foreign struct 'cairo.Context' occurs when click on blank canvas
May 30 to June 5
- Solved TypeError: Couldn't find conversion for foreign struct 'cairo.Context' by
sudo apt-get python-gi-cairo
This package is a Python Cairo bindings for the GObject library
- If problems occur when installing gaphas by
sudo apt-get install python-gaphas
Check the universe repository before installation may help
