Hiya. Does anybody who has & uses VTune know how I can use the code coach when I''m using an external library (DirectX)? I click to run it, and get: d:\work\project\MainHeader.h(11) : catastrophic error: could not open source file "D3D8.h" #include ^ I''m running it from a makefile, but I don''t see anywhere to add extra include folders. Thanks in advance for any help. I''ll check Intel''s site too but they seem to be down. Or at least the link from here to there is.
