Hi,

You may create these directories (.deps and .objs) in your source file directory by hand.

If you "export" Makefile you will see commands to create these directories.

mandrav:
The point is that they should be automatically created...
Maybe the folder is read-only or you don't have write permission? Or are you working on a read-only medium (like a CD)?
If none of these are true, please export the Makefile and post it here.

Yiannis.

mandrav:
OK, it appears that the project previously had a file main.cpp which you apparently renamed to c_main.cpp. The dependencies were generated for the main.cpp file, which is now missing (as a matter of fact, the dependencies for main.cpp are missing - the .deps/main.d file).
There are two solutions for this:

a) Click "Compile/Dist clean" and re-compile, or
b) manually delete the .deps folder inside your project dir and re-compile...

HTH,
Yiannis.
