[code]

Code:
JAVAC = javac
JFLAGS =

SUBDIRS = main_dir subdir1 subdir2

        @@for file in $(SUBDIRS); do
                 $(JAVAC) $(JFLAGS) *.java

If my understanding is correct, each command is taken as one single line, so you need to write the loop as if on a single line.

Maybe you try this:

Code:
JAVAC = javac
JFLAGS =

SUBDIRS = main_dir subdir1 subdir2

all:
        @@for file in $(SUBDIRS); do \
                 $(JAVAC) $(JFLAGS) *.java; \
        done
Also make sure the whitespace before the command are all real tabs.

If you still have problems running it, please don't forget to post the error message to help others help you.

Why don't you use Ant (http://ant.apache.org)?
