 IMPORTANT NOTE:
 

+  wxMGL is currently in need of some work to bring it up to the

   If you experience problems installing, please re-read these

   osname.txt for your platform if it exists) carefully before
   mailing wxwin-users or the author. Preferably, try to fix the
   problem first and then send a patch to the author.

+Scitech MGL must be compiled natively, and to do this you will need to download
+the following files (from the current/v2 and current/v2gnu directories). You
+should get the latest versions available rather than the exact versions shown
+below, they are just an example of what to look for:

+
+If you want to build wxMGL natively using the DJGPP compiler, you will have to

+The system you compile on must support long file names. You can use Windows 9x
