Function definition not found after calling other funtion

[monday]

Function definition is recognised, then some other function is called and suddenly the previous function spits acid to my face

Can it be a linking issue or there may be any other causes for that?

I'm not sure if it is compiler bug but it actually compiles without a problem even when it's underlined like this

Nope, since linking/compiling is not done on the fly. Looks like an IntelliSense glitch/bug. Code compiles fine and no error is thrown regarding those.

It happens to me in a fork of a project that i use to test things, so it's messy/unarranged. 
Not in the original project, i would guess it's something to do with include files/dirs or project settings.

Try adding them to your actual solution, this happens usually if you have included some files only via "Additional Include Directories". If that not works it may be a glitch and/or mismatch between compiler / IntelliSense versions.
