RE: Making multiple projects with one makefile

[Norris, Nelson [LBRT/LNA]]

I had posted this original message a couple of months ago, and got a
response.  However, after trying the proposed solution, I still get the
following error:

NEW MAKEFILE
------------

MAKEDIRS = controlBoard displayBoard serialOptionBoard
all:
    $(foreach dir, $(MAKEDIRS), $(MAKE) -C $(dir);)

NEW ERROR
---------

gmake -C controlBoard; gmake -C displayBoard; gmake -C serialOptionBoard
gmake: *** controlBoard;: No such file or directory.  Stop.
gmake: *** [all] Error 2

Now the ';' separates the command into 3 separate commands, but now it tries
to pass the ';' as part of the directory name!

Is there another solution other than using the foreach command?  Or am I
still missing something?


Regards,


Nelson

I am looking for assistance in creating a makefile that will navigate a tree

>>RESPONSE<< Note the semicolon before the final close-paren.

The response I get back from GNUmake is the following text:
 
gmake[1]: Entering directory `C:/_projects/mainProject'
gmake -C controlBoard  gmake -C displayBoard  gmake -C serialOptionBoard
What you wanted was:
gmake -C controlBoard;  gmake -C displayBoard;  gmake -C serialOptionBoard;
The lack of the semicolons causes the shell to interpret all the tokens
following "controlBoard" as arguments to the first gmake command. The second
"-C" argument to gmake causes it to try to descend into the
controlBoard/displayBoard subdirectory, which doesn't exist, hence the error
messages:
gmake: Entering an unknown directory
gmake: Leaving an unknown directory
