Trying it out right now on the qemu

rvs · 03-21-2011, 05:28 PM

Can you explain how the logging works (LOGPRINTF and WARNPRINTF)? I can't find the location of these logs.

Thanks

Hi rvs,

Every component has a files called log.h (or something simular) to control the logging of LOGPRINTF, WARNPRINTF and ERRORPRINTF. Default only WARN and ERROR are enabled. The output (default) goes to stderr.
To see the output on the emulator, you can press Ctrl-Alt-3. Pressing Ctrl-Alt-1 brings you back to the UI again.

Thanks Marcel, very useful information.

Do you develop using Anjuta? I'm guessing it's probably easier that way to quickly test small changes and turn logging on/off, but I still need to figure out how to import the Hackx source code into a (new) Anjuta project.

I use all different kinds of editors on linux and windows to change the code. But for most of the components of MackxPatch I use Anjuta projects. However I do not build using Anjuta, I am used to embedded software and thus also to compiling from command-line.
I use different Anjuta projects for every firmware component (ctb, popupmenu, sysd, etc). One of them I use to start qemu. For each component I also have a separate shell, to execute the make (with correct parameters) and copy the build executable to the qemu (using scp). I have 3 desktops/workspaces, left for the command shells, middle for the Anjuta projects and right for the qemu and a shell that is logged into the qemu (ssh qemu, just press enter for password).
For the commands to type I have a 'que-card', see attached file.
'Creating' an Anjuta project is very easy, copy the one from helloworld to the 'root' of one of the firmware components, rename it and start it.

Hope this helps.
Marcel.

Thanks, it's both helpful and interesting

Interesting.

My DR development environment: a VirtualBox linux virtual machine, with 4 virtual desktops:
1. qemu, a gnome-terminal with 3 tabs (mainly for scp and qemu shell), and a second gnome-terminal with many tabs (for compiling, light editing, copying/moving files and a shared directory from my real desktop)
2. emacs
3. firefox, with some help html files. Btw, when hacking DR firnware doxygen generated files are quite useful
4. evince, a pdf reader

EDIT: I didn't mention I don't use anjuta at all... it doesn't give anything emacs + shell couldn't offer

Thanks Iñigo,

I haven't heard of doxygen before. What do you use it for?

Very interesting, thanks! It seems quite extensive. I'll try it out (in due time).

It's very useful to study third party code.
Doxygen is a package which parses specially formated sources and generates this kind of documentation.

If you want it I can attach here my doxygen configuration in order to help you generate your own docs, as they are big enough to forbid publishing them.

I would very much appreciate that!

There is also a graphical UI tool for doxygen named doxywizard , you can run it and load the provided config file to modify the output.

Thanks again.

I'll try out Doxywizard, too.
