I did some 3DFX programming a year ago.
Now i have time to continue but i forgothow to link libraries and make the includes.
So now i just get link errors, can someone tell me how and where i assing the lib and includes in MS Vis C++.

I haven't personally used the Glide API, but I would imagine that you would do it in the usual way. However, if it relates to something specific to the API then I would suggest consulting the API documention or 3Dfx's web site.

First make sure that that MSVC knows which directories to look in for the libs and includes, wether this may be the default include && lib directories or an outside source. To do this, go to:
Tools->Options and then click on the Directories tab. There you can set the directories (if the libraries/includes are not the default ones). Then, go to:
Projects->Settings and click on the Link tab. Edit the Object/Library field to include your libraries. Then everything should work. Good luck!
