Not able to clean the project

[Hrishikesh]

Each time I right click on the project and say Clean Project I get the following error:

21:15:14 **** Clean-only build of configuration Debug for project nrf24L01P_F407VGT6Disco_RX ****
make -j3 clean 
make: *** No rule to make target 'clean'.  Stop.
"make -j3 clean" terminated with exit code 2. Build might be incomplete.
 
21:15:15 Build Failed. 1 errors, 0 warnings. (took 85ms)

Where are the make files located and how do I resolve this error?

Normally this error can be ignored. In Eclipse CDT managed build system, there are normally no makefiles (visible to user).

On Windows, make sure that the builder type is set to "internal" (on other OS typically too, unless you know what you're doing).

P.S Of course if this is a 3rd party makefile and non-ST project - ask whoever gave your this makefile.

Thanks. With a default installation on Mac, this was set to external.
