Hello, @davidrihtarsic,@Quantasy, same problem, solved with @LaserTron solution. I have another issue : which font is used in mblock menu because I only see squares instead of letters....

@davidrihtarsic,@Quantasy

I had the same problem and was able to fix it. The first block in the error message (involving javascript) is due to the fact that the program crashed, but still has a running process. To fix it I rebooted the system (though mabe killing the right process would do the trick.)

The second error, the pango-ERROR, is due to a non-backwards compatible update to pango. To fix that I installed the pango-legacy package, which was made precisely for this sort of problem. I then had to use the following command:

LD_LIBRARY_PATH=/opt/pango-legacy/usr/lib:$LD_LIBRARY_PATH mblock

Which first tells the system to load the old pango libraries prior to running mblock.

pango-legacy should be added as a dependency and there should be a sensible way of making mblock load using the correct libraries.

Same error here:

$ mblock

Maybe I am missing a thing, but mblock won't start, but consumes 100% CPU

Here is the simple console output:

$ mblock /opt/mblock/resources/tools/arduino app listening on port 7070!

(mblock:16054): Pango-ERROR **: 09:12:29.594: Harfbuzz version too old (1.2.7)

?

mblock can't start.

@vn158 : I added it.

'gconf' is missing in 'depends'

I got "Upload failed" when trying to program my sons mbot, and it turns out that the toolsuite included in the package depends on older libs.

By installing avrdude from Community and replacing the package version with a symlink to the installed version I got it working.

sudo rm /opt/mblock/resources/tools/arduino/hardware/tools/avr/bin/avrdude
sudo ln -s /usr/bin/avrdude /opt/mblock/resources/tools/arduino/hardware/tools/avr/bin/avrdude

The other parts of the tool suite seems to work for now (cross compiler, ...), but I'm guessing it can break anytime. I will look into replacing the entire tool suite with an Arch installed one (when I get the time).

@amiad: I think that I understand what's the problem:

When loading a project, the program first tries to save the current project (even if it's empty). Apparently the default auto-save path is /opt/mblock/resources/web/tmp/project.sb2

My workaround was to set the permissions on this file to 777.

Hopefully there's a better solution, like a setting for the default auto-save path. I'll file a bug on mblock github.

Thanks again for the help.

@eyal: check the permissions of file. You can open bug in github.
