Yes. For C++ you need a makefile with a check-syntax target. flymake
calls the check-syntax target with CHK_SOURCES set to a filename. This is
needed because flymake does not know about your includes files etc. For
same languages (eg. Perl) flymake can work without the Makefile.

Take a look at the example in flymake/samples/make-based/cpp/Makefile
(from flymake-0.2a.zip)


Also, here are two lines from one of my own makefiles

check-syntax:
	g++ -O -Wall -g $(INC) $(CHK_SOURCES)
