This is exciting!

Great work, keep meaning to get a Raspberry Pi but real life keeps getting in the way!

keszegh

great, i got to get a pi.
let's not forget that some of us promised pi versions of our games/apps for those who donated enough. how can we do that? can i somehow compile my app to pi from a windows gideros studio?

SinisterSoft

We can do it very soon - John is working on a 'native' player that ignores X - then it will be a regular export option.

Hopefully Arturs or Nico will be able to add the code to make it into a standalone player too - One of them added it to the RT player, but I'm not sure who.

Does Gideros work on Linux?

ar2rsawseen

@jdbc yes I think so, but currently we don't have a build power to provide Linux builds too

john26

@jdbc, yes, you can also compile Gideros on Linux (tested on Ubuntu). Please follow these instructions:

Also, I've now got the no-Qt, no-X Raspberry Pi player to work for a simple test example. It runs at 60 fps! You can see the panel appears in front of the entire X-Windows system and cannot be moved or resized. This is a work in progress and I still need to add OS events (mouse/keyboard)

This is great, I guess Linux and Raspberry do not need QT libraries.

Gideros Studio compiled in my Ubuntu 14.04.

I will try Gideros Player later. I have created one symbolic links to find qscintilla library from compiled.

jdbc

I have compiled Gideros Player. It does not shown any images, only traces:

Gideros Studio does not display well in Ubuntu 14.04. I have used Qt5.5 to compile.

SinisterSoft

looks like qscintilla is messed up - did you compile it or get it using apt-get ?

SinisterSoft

re Gideros on the Pi, qt player...

If you use this build of Raspbian then you can get the player running faster...
http://dri.freedesktop.org/wiki/VC4/

btw The preferences>configuration util did not resize properly, but the terminal>raspi-config did work.

I have downloaded Qscintilla from sourceforge and compiled in local.

SinisterSoft

try it with:

sudo apt-get install libqt5scintilla2-dev

jdbc

May be use Docker with all dependencies preinstalled will be the best to use Gideros and Linux.

jdbc

try it with:

sudo apt-get install libqt5scintilla2-dev

Same problem with editor.

ar2rsawseen

Could it be font size/ scaling problem?

jdbc

Could it be font size/ scaling problem?

The problem with Gideros Studio is solved when UI and Editor Theme is loaded.

Gideros Player is still not working, runs but does not show nothing in the display. Ideas?

jdbc

It seems that Gideros Player works but focus is not obtained... it is behind all windows.

Views-> Always on top and solved. But it runs slowly, toooooo slow.

jdbc

Plugins must be compiled in Ubuntu... how to include gideros.h and lua.h file?

SinisterSoft

Turns out that the player on the Pi needs to be set to unlimited fps in order to run at 60hz using the new build of Raspbian that I linked to...

jdbc

Does anybody know why Gideros Player runs slowly in Ubuntu? May be compiler flags?

SinisterSoft

Try running the player with the framerate set to unlimited. If that works then there is something wrong with the frame rate sync as I had to do that on the Pi to get it to run at 60hz using the hardware accelerated X on the Pi.

If not then maybe Ubuntu has a software OpenGL implementation?

Unlimited FPS solved the problem, but plugins must be compiled. I was studying Docker to provide a container + Gideros Studio.

SinisterSoft

There must be a bug with the linux build then when getting the value maybe for the frequency? John might know more?

john26

@SinisterSoft, I'm afraid I don't at the moment. Probably a minor Qt bug. Will look for a work around but in the meantime, unlimited is the way to go.

I'm trying to install the freedesktop version of Raspbian from the site you linked. The first link goes to several files one of which is called:

20151220-1053-vc4-image.zip

I assume this is the only file I need, right? I just burn this onto the Pi's SD card?

john26

@jdbc, you should be able to build the plugins using this script

https://github.com/gideros/gideros/blob/master/scripts/buildplugins.sh

(you may need to adapt it slightly, it's designed for Mac)

Basically the script goes to the "plugins" directory and runs qmake on all of the .pro files. You then need to copy the resulting .SO files to the Gideros install directory where the player can find them.

SinisterSoft

@john26 yes, inside that zip will be the image to flash to the memory card.
