I checked my project settings, they are clearly set to Release not Debug. What could be the solution here?
BTW: Why does the CB template produce DX8 code instead of DX9?? Or why is the desired version not chosable in the Wizard?
darthdespotism:

--- Code: ---#pragma *
--- End code ---
depends on the Compiler. As far as I know MinGW does not support this way of linking libs. You should either use the included (?) DirectX9 - libs named correctly (libd3d9.o) via -ld3d9 in the build settings (or try -d3d9.lib at the same spot, not sure if this works)
Project->Build Options->Linker Settings
patlecat:
Thanks but that doesn't help.
I found that there are some settings that I cannot change in CB, and I really don't know where they are :? Why is it always trying to compile in Debug? And why is it using this -ld3d8 option when in fact I added the d3d9 lib?

undefined reference to `Direct3DCreate9@4'
BTW I found out that in the project settings the Release build was set to "GUI mode" whereas the Debug build was set to "Console"!
patlecat:
Ok part of the problem is solved because I manually changed <Add library="d3d8" /> to <Add library="d3d9" /> in the ".cbp" File. But this is not a correct behavior of CB!
Still it compiles as Debug instead of Release.
patlecat:
Here is the content of my project file. What must I change to have a normal Release build?
