did you follow these directions for wxWidgets?
http://wiki.codeblocks.org/index.php?title=Installing_Code::Blocks_from_source_on_WindowsIf you used the above directions you used you should find an dll in the folder lib\gcc_dll wxmsw26u_gcc_custom.dll (This assumes Unicode NON-debug Build)
2. The #wx directory should have folders called include, build, lib and the others that go with them right under it.
If you are getting an error creating the DLL, I used directions from this URL to get around it for me.
http://www.mameworld.net/mrdo/compile.htmlHere's the part from the link that matters.
You should now have a folder with the nine subfolders as shown on the right. Now, extract the dx80_mgw.zip to your C:\MinGW folder. Make sure you have the option Extract Relative Paths or similar checked in your unzip utility. This is because each file is archived using the same folder structure, and you want the right files to be in the right folders. If you are asked to overwrite files at anytime, do so.
dx80_mgw.zip is at this URL
http://alleg.sourceforge.net/files/dx80_mgw.zipI tend to get the error doing NON DLL or Debug builds, but I did get it once on the regular DLL build.
Since, I build Mame alot it could be I always used a patch minGW before that one failure.
