here is the output from the console in Eclipse:
**** Build of configuration Debug for project FatFstest ****
make all
make: *** No rule to make target `main.o', needed by `FatFstest.elf'. Stop.
I am trying to build a project using the AVR plugin for Eclipse to test the FatFs library. I first imported the FatFs code then created main.c file to implement it. After I tried building it the first time, I added the src folder of my project to my the directories list in Properties > AVR Compiler > Directories, and I still get the build error. Any help?
Here is my makefile:

It happened to me too, simply moving main.cpp in an another folder.
I try to clean out the project, but the problem persist, so I have deleted Debug folder, re-compile and it works!
