Hi, thanks for your answer. Yes if I remember correctly I could generate with Visual 2008 a non-empty (but non-tested, short of having a .lib) DLL for Agar-core and, I think, Agar-gui as well (not sure), with little or no change in the code (version 1.3.2).
The build failed with the project files which were automatically revamped from their Visual 2005 counterparts, but I had anyway to create my project files from scratch, as I will build by script Agar among a larger set of libraries (see http://osdl.sourceforge.net/OSDL-latest/LOANI.html). Hence my need to be able to specify to the configure script prefixed installation of Agar's prerequisites (ex: SDL, libjpeg as well I think, etc.). For what it's worth, here are the files I then checkined: http://osdl.svn.sourceforge.net/viewvc/osdl/OSDL/trunk/src/conf/build/visual-express/Agar-from-LOANI/ I have little chance to be able to investigate the Windows build before ~10 days, but I would be glad to test it then. With the -pedantic flag you will find that there are some multiple declarations of functions in headers. Probably the most serious fix would be the one in string_compat.h, as it looks really like a bug. Finally, thanks a lot for the Agar library, I intend to make heavy use of it, as finding a good GUI over OpenGL does not seem easy. Best regards, Olivier. Julien Nadeau a e'crit : > Hi.
