OK, after following the instructions on the link I get the following errors when compiling in Codeblocks
"game - windows" uses an invalid compiler. Skipping...
"ufo2map - windows" uses an invalid compiler. Skipping...
"ufo_ded - windows" uses an invalid compiler. Skipping...
"ufo - windows" uses an invalid compiler. Skipping...
Nothing to be done.
I noted that Codeblocks autodetected Visual Studio 2005 and Cygwin GCC on my system when I started it up. I did not have an actual GCC for windows proper installed and I suspect that is what is missing - can you confirm that your Codeblock pre-package does not include a compiler ?? or is MinGW a compiler in its own right
Note that I interpreted the wiki instruction "copy the dynamic libraries from ../../contrib/ to a directory in your path" by adding the full path to the "contrib" directory in the SVN copy to my systems "path" environment variable, although I suspect that even if I screwed up with this it is not the cause of my build errors.
