Mfile - a simple Makefile generator for AVR-GCC
================================================
[See below for installation instructions]
General
-------
The main purpose of this small application is to provide people an
easy way to setup their project's Makefiles for »relatively standard«
projects, so one could start using AVR-GCC without first studying the
AVR's datasheet, plus the avr-libc documentation (really
recommended!), /plus/ the »GNU make« user manual.
It cannot really release the potential programmer from eventually
studying the »GNU make« manual, but it can help to delay this part a
few months.
This generator works by using a Makefile template (the one that
currently ships with WinAVR), load it into an editor buffer so the
user can view the file and the changes, and then use a menu-driven
approach to customize that buffer. Eventually, at the user's
discretion, this editor buffer can be saved into a Makefile.
(Optionally, the user can also edit the buffer directly, so it acts as
a simple text editor.)
While the Programmer's Notepad 2 (PN2) editor that ships with WinAVR
intends to eventually implement this functionality some day, there are
two reasons for this little project:
. Act as a stop-gap measure so users will get something they can use
right now, without waiting any longer.
. Since this tool is written in Tcl/Tk, it is also portable to Unix
systems, so Unix users (who'd never benefit from PN2) might use it.
I do explicitly /not/ intend to make this tool the all-singing
all-dancing scriptable Makefile generator that can emit any Makefile
for any processor and compiler on earth. I really do not want to
spend that many more hours into it, it was intented to be a quick and
(hopefully not so) dirty tool that gets finished within a couple of
evenings, and won't cost me another dozen of hours per months for
supporting it, adding new features etc. If you feel this is worth
porting somewhere else (like for the MSP430-GCC that is probably
fairly close to AVR-GCC in terms of typical use), please pick it up,
extend it, and maintain it separately. As always, I appreciate
feedback, but reserve the right to ignore anything that tries to
extend this tool above the outlined original purpose.
Note that the Makefile template as shipped requires GNU make for
various things (automagic dependency generation, some inference rules
are written in gmake syntax as well). However, as Mfile only relies
on a few macro names in the template, it should be relatively easy to
modify the template for other »make« dialects. The template (or input
file upon »File -> Open«) will be parsed when reading it, and only
those features actually present will be displayed in the »Makefile«
menu. So if e. g. people don't want to include AVRdude features, they
can delete all related lines from the template. Also if someone (like
Unix users, in particular those not using GNU make) want to modify the
way the dependencies are generated (e. g. by using the traditional
»make depend« approach), this should be completely unrelated.
Prerequisites
-------------
Requires the Tcl and Tk toolkits in recent versions (no exact version
known, probably any 8.x version is OK). Current WinAVR (20030913)
contains these tools.
As an alternative to the standard Tk wish interpreter, the tix
toolkit's tixwish interpreter can be used. Under Unix systems, the
look & feel is then closer to what Tk wish looks like under Windows.
Installation on Windows
-----------------------
[Users of WinAVR 20040404 and beyond do get Mfile pre-installed. See
below for upgrade instructions.]
Extract the archive into a subdirectory of its own, e. g.
c:\WinAVR\mfile
Double-click on the icon for »mfile.tcl« in your file browser
(explorer), and tell it to use c:\WinAVR\bin\wish84.exe to run this
file. (Adjust appropriately if you installed WinAVR in another
directory.)
Since Windows always changes to the directory of the application
before starting it, all template and auxiliary files should be found
easily there without editing mfile.tcl. Note however that this
directory will also become the default directory where »Makefile« will
be stored, unless you change a different location with »Save As...«
As another option, the following has been contributed by Eric Weddington
on how to properly create a shortcut on the desktop:
1. Extract the mfile.zip archive into your WinAVR
installation directory. This will automatically create a
subdirectory \mfile with all the needed files in this
subdirectory.
2. Create a Shortcut on your Desktop.
3. For the location of the item, select the program
wish84.exe which is located in \bin subdirectory of your
WinAVR installation directory. Add a space and then type
the absolute pathname of the program, mfile.tcl, which is
located in the mfile subdirectory of your WinAVR
installation directory.
For example, if your WinAVR installation directory is at
C:\WinAVR, then the item will look like:
C:\WinAVR\bin\wish84.exe C:\WinAVR\mfile\mfile.tcl
4. The name of the Shortcut should be: MFile
5. When finished, you will have to go back and properly
select the Start Directory. Right-click the shortcut icon
on your Deskopt and select Properties. In the Start In edit
box, put in the mfile subdirectory of your WinAVR
installation directory. NOTE! This is essential if MFile is
to execute correctly as there are additional files that it
needs to find.
For example, if your WinAVR installation directory is at
C:\WinAVR, then the Start directory will be:
C:\WinAVR\mfile
Installation on Unix
--------------------
Extract the archive into an arbitrary subdirectory, like
/usr/local/share/mfile
If a different directory is chosen, edit the setting of »prefix« on
top of mfile.tcl to match the installation directory, or alternatively
use the environment variable MFILE_HOME to override the default
setting.
If you'd like to use a different interpreter than
/usr/local/bin/tixwish, edit the #! setting in the first line. The
standard Tk wish interpreter is supported as well as the tix toolkit
one.
If you prefer, create a symbolic link for convenience (so the
application can be found along your default $PATH setting), like
ln -s /usr/local/share/mfile/mfile.tcl /usr/local/bin/mfile
Remember to edit the file makefile_template to suite your needs (e. g.
default settings, adaptation to non-GNU make utilities).
Upgrading an Mfile installation on WinAVR
-----------------------------------------
Starting with WinAVR 20040404, the WinAVR collection is shipping Mfile
pre-installed. (After all, the WinAVR users have once been the
primary reason to develop Mfile at all.)
In order to upgrade the Mfile files supplied with WinAVR, extract the
archive into some directory, and copy all the files into
<winavr directory>\mfile
That ought to be all that is to be done.
