Hi,
When Geany is started from the Gnome menu it doesn't get environment variables set in .profile, .bashrc etc. Other window managers seem ok.
This means that builds don't see CFLAGS, python executes don't see PYTHONPATH etc :-(
Although builds and executes run in shells, a non-interactive shell does not load any startup files.
The attached patch adds the option (-l) to run the build and execute shells as login shells which will load startup files.
Two hidden prefs build_in_login_shell and exec_in_login_shell allow you to disable this for builds or executes respectively if running your startup scripts causes some problem.
Cheers Lex
