dmenu 0.1 should work with booboo's latest rootfs without recompile. However I've made some minor changes to go inline with his rootfs. Hence dmenu 0.2. Enjoy.

Changes in 0.2

- Dynamically link against libconfuse since it's provided by the rootfs. dmenu binary is now smaller
- Remove the mechanism to restart dmenu after the executed program has finished. This is not required anymore if you are using init to respawn dmenu.

For the above to work, you need to create a script file called /usr/local/sbin/main with the following content,

Code: Select all

#!/bin/sh
export SDL_NOMOUSE=1
cd /usr/local/dmenu
./dmenu


Note that you need to change /usr/local/dmenu in this script to the directory where you have dmenu installed.

<Edit>
I've decided to make the setup easier for windows users. Please download dmenu-0.2a.zip instead. It has all the directory structure in place (/local/dmenu and /local/sbin/main). Just directly unzip this file to your SD card and it should work automatically. Enjoy
<Warning: it might overwrite your existing /local/sbin/main. so take precaution if you want to keep your existing /local/sbin/main>

@rookie1: thanks for the update!

Just tried dmenu, but i get following error message:
cannot run ´usr/local/sbin/main´: no such file or directory

I edited "main" in notepad, maybe that's the problem?

/usr/local symlinks to /boot/local, which is your fat partition.
You need to create a /local direcotry on top of your fat partition for it to work.

Also, notepad isn't compatibile with unix endline characters, and can break every configure file. It shouldn't be used for editing any linux config files.
I have no idea what other text editor should be used instead, i don't use windows

I try to use notepad++ when on windows, seems to handle the formatting better and also does programming language recognition

I wanted to ask how to make the script, but then i refreshed the thread, awesome! I got it working!!!

Thanks rookie, this works great, and is incredibly easy to set up.

Notice that we are forcing the shell executable stuck in memory JUST to set the SDL_NOMOUSE environment variable.

I will patch SDL in the toolchain/rootfs to set SDL_NOMOUSE=1 by default. Please keep an eye on the next release and when it's used widespread please consider releasing a Dmenu that places the true executable in local/sbin/main instead of a shell script.

Is the wallpaper limited by a certain amount of colors?
Every image i try looks like it has lost colorinformation. A bit like when you compress a jpg to a 256color gif.

The color banding is due to SDL dithering from 24 bit (the PNG file is 24 bit) to 16 bit (Dingoo screen is at 16 bit). Unfortunately I haven't been able to find a way to save a 16 bit PNG image. However, if your wallpaper does not use many colors, you can save it as a 256 color PNG image in your image editing program. It should look much better than what SDL is doing. You can check out the wallp.png I have included in dmenu 0.2. It's a 256 color PNG and looks better than what comes in dmenu 0.1.

I was wondering whether is it possible to make dmenu able to launch application in background.

For instance, I'd like to be able to launch a console-based music player in background, while running a framebuffer-based app (like an ebook reader) just like is possible with the original firmware.
