example with automatic generated dependencies, object files not generated

[Torsten Mohr]

Hi,

i created an example project that i attached to this mail.

The structure of the project is like this:

|-- Makefile
|-- dep
|-- obj
|-- perl
|   |-- autodep.pl
|   `-- common.pl
`-- src
    |-- file
    |   `-- SRC
    |       |-- file.c
    |       `-- stat.c
    |-- gui
    |   `-- SRC
    |       |-- gui.c
    |       `-- window.c
    `-- net
        `-- SRC
            |-- net.c
            `-- socks.c

When i type "make", the dependencies are generated automatically,
some files that for "file.c" look like:

file.o file.d :
        src/file/SRC/file.c

There are no files included from "file.c", so "file.d" looks fine
to me.

1.
In the Makefile i have to write the rule to create the dependency
files BEFORE including them.  Why is it like that, i don't understand
that.

2.
When i type "make", the dependency files are generated, THEN the command
to link the ELF file is executed, but the object files are NOT yet made.

Why does this NOT work, i don't understand that, i clearly stated that
for generating the ELF file, the objects need to be there.  Is this
related to the automatically created dependencies?

How else do i need to write the rules for the objects and/or the
automatic dependencies?

The behaviour is the same on Windows and on Linux.


Thanks for any hints,
Torsten.
