flymake configuration error for C program

[Corey Foote]

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 <stdio.h>

    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!

And, of course, I'm using tabs in the makefiile as necessary. It compiles fine when I just run "make" from the shell.

Running make like this fails for me:

make -s -C ./ CHK_SOURCES=helloworld_flymake.c SYNTAX_CHECK_MODE=1 check-syntax

You need to expand your makefile to have a check-syntax target, which
should take the name of the file you're editing in CHK_SOURCES.

Set this if you want to get some logging from flymake in your
*Messages* buffer:

(setq flymake-log-level 3)

HTH,

I tried this today as well. Here is the answer :
