When trying to run M-x Flymake-Mode in Emacs I get: Flymake: Configuration error has occured while running (make -s -C ./CHK_SOURCES=helloworld_flymake.c SYNTAX_CHECK_MODE=1 check-syntax). Flymake will be switched OFF I am invoking the command in a buffer called helloworld.c: #include int main(void) { printf("Hello World"); return 0; } And have a file called Makefile in the same directory: helloworld: helloworld.c gcc helloworld.c -o helloworld I'm running GNU Emacs 23.0.91.1 under Ubuntu 9.04. Thanks in advance! _________________________________________________________________ HotmailŪ is up to 70% faster.
