macOS Does compiler have memory?

[ellie:)]

It returns me the same error even though I have changed the code.

Eg: 'struct Keypoint' has no member named 'printkeypoint'

but I had changed the 'struct' to 'class', still it insists there is 'struct Keypoint' with no member named 'printkeypoint' (and I am pretty sure there is such member in the class).

I tried to open a new header file, copy and paste the code from the old one, and delete the old one, empty the recycle bin. Still, it insists there is a 'struct'.

Can someone help me?

Post the code.

There are times when a setup like make won't know a header changed because its dependency is a .c file, etc. but that may not be the case here.

Did you mean that I should change my makefile ? What should I do to my makefile?

hi, I have solved the problem. It seems that the compiler had tried to look into my gch file.. Many thanks
