remogatto / mandala Goto Github PK

From commit owenthereal/gotask@9649e4c gotask supports flags of type string. Mandala can now use the official gotask for black-box test execution.

How to don't update？

At the moment there is not sound support for desktop. Possible technologies are:

• PortAudio for the sound engine
• libsndfile for handling audio files

Hi dude!
Sometimes I catch the following seg fault, after creating an app and playing with worlds, boxes, etc. It happens when I close the window.

(From inside an app generated via mandala-template):

$ gotask run xorg

Hi Andrea,

I currently have a desktop application coded under OpenGL3 [1], and I want to embed it into Mandala [2].
Because the desktop version is based on go-gl/gl, I couldn't use remogatto/opengles2, there was too much changes. So I cloned go-gl/gl and hardly delete the code that doesn't exist in the OpenGLES implementation.
I tried first to compile under OpenGLES2 but I finally get stuck because of missing methods about vertex arrays (glBindVertexArray etc...). Indeed those methods are only here since OpenGLES3.
So I switched to OpenGLES3 but I still have compilation errors about the same methods.

Si I wonder if Mandala can support OpenGLES3 ?

Few are going to take this project seriously with that name. You really should consider calling it something else.

Not sure if it's related to mandala but when I'm really stuck here.
When I execute gotask run android (even with -a flag), I get the following errors :

$ gotask run android

I'm under Ubuntu 14.

I'm trying to build the Mandala samples under OSX.

The issue I have at this time is the OpenGL library links. The following commands fail :

$ go get github.com/remogatto/egl
# pkg-config --cflags egl
Package egl was not found in the pkg-config search path.
Perhaps you should add the directory containing `egl.pc'
to the PKG_CONFIG_PATH environment variable
No package 'egl' found
exit status 1

$ go get github.com/remogatto/opengles2
# github.com/remogatto/opengles2
../projects/go/src/github.com/remogatto/opengles2/opengles2.go:29:10: fatal error: 'GLES2/gl2.h' file not found
#include <GLES2/gl2.h>
         ^
1 error generated.

On OSX the OpenGL libraries are located under /System/Library/Frameworks/OpenGL.framework. This is the header files listed in that directory :

$ ls /System/Library/Frameworks/OpenGL.framework/Headers
CGLContext.h        CGLMacro.h      OpenGLAvailability.h    glext.h         glu.h
CGLCurrent.h        CGLRenderers.h      gl.h            gliContext.h        gluContext.h
CGLDevice.h     CGLTypes.h      gl3.h           gliDispatch.h       gluMacro.h
CGLIOSurface.h      OpenGL.h        gl3ext.h        gltypes.h

There is no glew.h or gl2.h so even if I create a symbolic link in /usr/local/include, it won't work.

A bunch of shortcuts are needed in order to interact with the desktop application mimicking the device. We need at least shortcuts for:

• rotating the window to simulate the rotation of the device
• pausing/resuming of the application
• exiting from the application
