A couple of years ago, I used TWS (ie. v2tk/mttws121.zip) to create a
Minesweeper clone. Recently I wanted to add a screenshot function. After a
couple of minor errors/warnings, it compiled fine, but I'm getting "undefined
references" at the linking stage. The errors look like this:

board.o: In function `BoardWindow type_info function':
board.cc(.text+0xa3b): undefined reference to `Window type_info function'
board.cc(.text+0xa43): undefined reference to `Window type_info node'

where BoardWindow is inheriting from the Window class. Is there something I'm
missing, or does the TWS library need recompiling?

Jason Hood.
