Last time I tried $(shell /usr/bin/wx-config), there was immediate hollering about build problems with it. There wasn't time to investigate at the time.
One problem with $(shell /usr/bin/wx-config) is it will pick up any version (wx 2.8 ) and any configuration (non-UTF-8 ) of wxWidgets that happens to be there. -lwx_gtk2ud-2.9 only matches the right configuration. It fails if wxWidgets was built with the wrong configuration.
Iirc, chatting in #wxwidgets on freenode, the devs there were baffled why that was used.
Did they say why they were baffled?
This is because on my system the path is /usr/include/wx-2.9/wx/wx.h
Why is it there? Was it included by the OS, or did you have to build it? If you built it, I wonder why it would put itself in a different place.
Has wxWidgets 2.9 finally started to become available as a debian package?
Maybe we should do this:
Again, those paths help make sure it's only 2.9 and will fail with 2.8.
wxWidgets 2.8 comes in ANSI and UTF-16, both wrong for us. It's tempting because it's so easily available as a package; a lot of people were frustrated by it until we started hardcoding 2.9 into the makefile.
