Automake Variables to tidy up Makefile.am

I have a directory /src containing all of my source files, and /bin to store all binary after running make command. The directory is something like below:

/BuildDirectory
- - /src
- - /bin
- - configure
- - Makefile.am
- - configure.ac 
- - ...

Now in Makefile.am, I have to specified:

bin_PROGRAMS = bin/x bin/y bin/z bin/k ...

bin_x_SOURCES = src/x.cpp
bin_y_SOURCES = src/y.cpp
bin_z_SOURCES = src/z.cpp

Is there any variable that can help to get rid of all "bin/" and "src/" ? For example I just specify:

$BIN = bin
$SRC = src

And they will look for the correct files in correct folders and compile it to the correct places.

Thanks

You could take advantage of remote building. Place this makefile in the bin dir:

VPATH = ../src
bin_PROGRAMS = x y z k ...

x_SOURCES = x.cpp
y_SOURCES = y.cpp
z_SOURCES = z.cpp

Now replace the current Makefile.am with this one:

SUBDIRS = bin

Now tweak your configure.ac to also generate bin/Makefile 

AC_CONFIG_FILES([Makefile
        bin/Makefile])

and you should be set for life.

If what you're trying to do is what I think you're trying to do, you're trying to achieve something like:

SRCDIR  = src
BINDIR  = bin

bin_PROGRAMS = $(BINDIR)/x $(BINDIR)/y $(BINDIR)/z

bin_x_SOURCES = $(SRCDIR)/x.cpp
bin_y_SOURCES = $(SRCDIR)/y.cpp
bin_z_SOURCES = $(SRCDIR)/z.cpp

I've tested this a few times in various forms, and it won't compile the code as it would with your example; I somehow convinced it that it was compiling C at one stage:

gmake[1]: *** No rule to make target `bin/x.c', needed by `x.o'.  Stop.

I'm thus fairly certain that it's not possible. Sorry.

Not to my knowledge. If you're looking to separate your compiled files from your source files, remember that you can build outside of the tree:

$ cd foo-1.2.3
$ mkdir build
$ cd build
$ ../configure
$ make
$ make install

If this is what you're looking to do, you can make the Makefile.am simpler by creating binaries without a directory prefix (and still referencing things in src/ by hand).
