It is indeed annoying and obviously buggy. 
I kinda "fixed" it last year but since I didn't had any serial port stuff to test it, it was just in abstract (Luc was using it, thought)

There was a report a couple of weeks ago to try using double slash. 

SerialPort new openPort: '/dev//ttyUSB0'

So I compiled two VMs, one with the SerialPlugin as an internal plugin, the other one as an external plugin.

On a Debian box, I connect an Arduino Diecimila board and I get its handler at /dev/ttyUSB0. However, on both VMs with fresh Pharo 2.0 images:

SerialPort new openPort: '/dev/ttyUSB0'

Fails with a generic error.

What's wrong with SerialPort? The "cannot open port" error message is about as informative as "sorry, not gonna happen" :(

Great! I was missing the gl and alsa headers. All done now, thanks a lot :)

Okay, it seems the patch is already included in the latest VMMaker image, so no need to apply it.

That's nice :). Anyone with grants in the issue tracker can close it?? :D
 

Still, having executed the script, I get yet another error, this time related to gl.h (why does it need it? I left B3DAcceleratorPlugin out):

Hmm, which configuration are you using to copile? I think there is a UnixNoGLConfiguration or something like that... So either you install the gl libraries or use the no gl configuration to generate the sources :).
In any case, I really don't know why there is that dependency with opengl...

ouch! I forgot to execute the script this time, and didn't install the patch either.. trying again, thanks! :)

Hi!

before compiling you have to, inside the build folder, execute codegen-scripts/extract-commit-info.sh

Besides, I was looking at luc's tutorial and it lacks one step to have serial plugin built: install the patch he made [1]. Did you do that? I added a comment in the blog entry just in case...

I found out how to leave B3DAcceleratorPlugin out, but now I get this error almost at the end of the compilation process:

"El fitxer o directori no existeix" is Catalan for "The file or directory does not exist".

How comes this header isn't there?

Ok, it seems the problem was not having the sources file in the same directory as the image.

Anyway, now I've another problem when trying to compile. cmake runs fine, but make fails with the following error:

Any ideas? 

(For the record, I do not need the B3DAcceleratorPlugin, so I guess it could just be left out, but I don't know how does one do that either)
