Re: [Linux-gpib-general] Python bindings

[dave p. <dpe...@gm...>]

After applying your patch I get:

Making all in python
make[3]: Entering directory
'/home/dave/src/linux-gpib-git/linux-gpib-user/language/python'
{ /usr/bin/python -m build && touch build; } || { rm -f -r build; exit 1; }
/usr/bin/python: No module named build.__main__; 'build' is a package and
cannot be directly executed
make[3]: [Makefile:501: build] Error 1 (ignored)
make[3]: Leaving directory
'/home/dave/src/linux-gpib-git/linux-gpib-user/language/python

without your patch I get:

Making all in python
make[3]: Entering directory
'/home/dave/src/linux-gpib-git/linux-gpib-user/language/python'
{ /usr/bin/python setup.py build && touch build; } || { rm -f -r build;
exit 1; }
