Error with assembly programming using eclipse IDE. subdir.mk

Hello, im trying to make a small code with assembly using eclipse IDE, but a strange error appears in a file called subdir.mk the ide does not tell the error just show the line:

@echo 'Building file: $<'

The assembly code itself doesn´t matter, if i put the directive "__asm" in the front of the code the error pops up, if i delete the directive the error will disappear so i think that is something related to the gcc compiler configuration that doen´t recognize the "__asm" directive, can someone help me?

Im using a .c file to program.
