GDevelop general Bugs reports

Hi. I don’t know if this is a bug.
I can’t run native linux games (the shmup example) on Xubuntu 14.04.2-64 and GDevelop 3.6.79.0
Problems with ParticleSystem::ParticleEmitter.

This is the terminal output:

Any idea?
Thanks! :slight_smile:

Are you sure the Particles extension is activated? :slight_smile:

Hi, thanks for the reply.
Where can I check that?
When I make a preview of the game, without compile, it works.

Yeah, in the editor GD loads every extension, so no matter if you active it or not, it will load. But when compiling, GD exports some extra files for every activated extension (I think it needs to do some links too) :wink:
Open the extensions window, you can find it in the left window (the Project manager), do a double click on the last item (Extensions)
Extensions.png
and check the Particles extension, if it’s already activated/checked, we have a problem :slight_smile:

Thanks Lizard-13 and sorry for the delay, I was traveling and offline.
Extensions are active, so must be another problem.
After Install GDevelop from the ppa, I checked some dependecies were not installed, for example gcc if I’m not wrong.
I will try then something like apt-get purge and reinstall GDevelop again.

A french guy from the forum complaint about that too. I fixed the bug (almost now) and sent a fix to 4ian (he is responsible for the Ubuntu build so you’ll have to wait a little to have the fix).
Meanwhile, you can copy the needed extension from /opt/gdevelop/CppPlatform/Extensions/Runtime to your game folder.
I’m currently sending the fix on OBS (for Fedora, OpenSUSE and ArchLinux).

Perfect, that worked. :smiley:
Thanks a lot.

Thanks for the quick fix Victor, I’ll release a new version with it.

Thanks for the update 4ian.
Now works correctly.
