when I try to compile a glsl shader with OpenGL in Ubuntu I get the following error: - 0:1(10): error: GLSL 3.30 is not supported. Supported versions are: 1.10, 1.20, 1.30, and 1.00 ES But when I do a "glxinfo | grep OpenGL" it says: OpenGL vendor string: X.Org OpenGL renderer string: Gallium 0.4 on AMD JUNIPER OpenGL core profile version string: 3.3 (Core Profile) Mesa 10.1.3 OpenGL core profile shading language version string: 3.30 OpenGL core profile context flags: (none) OpenGL core profile profile mask: core profile OpenGL core profile extensions: OpenGL version string: 3.0 Mesa 10.1.3

A strange issue with OpenGL 3.0 under Mesa 9.2.1 on Ubuntu 13.10 (64-bit) is observed. Variable definition with explicit precision (like this: highp vec2 v; ) produces an error: syntax error, unexpected VEC2, expecting ',' or ';' It seems like precision qualifier is disabled there for some reasons. Mesa Release Notes doesn't clear the situation -- not bugs, nor notifications are relative to the topic. P.S. with OpenGL ES 3.0 precision qualifier works correctly. Make sure you specify #version 130 . Without a #version directive OpenGL will default to #version 110 where precision qualifiers are

Ubuntu12.10(X86_64)上安装Mesa-8.0.4 由于最近项目需要接触OpenGL，实现软件渲染，Mesa则是OpenGL的开源实现。网址：www.mesa3d.org 1. 下载MesaLib-8.0.4.tar.gz，mesa-demos-8.0.1.tar.gz; 并解压 2. 安装Meas-8.0.4 1> ./configure, error：makedepend is required to build Mesa sudo apt-get install xutils-dev 2> ./configure, error: flex is needed to build Mesa sudo apt-get install flex 3> ./configure, error: bison is needed to build Mesa sudo apt-get install bison 4> ./configure, error: X11 development libraries needed for GLX sudo apt-get install xorg-dev 5> ./configure, error: Direct rendering requries libdrm>= 2.4.24 下载libdrm-2.4.33.tar.bz2，解压

Edited: I want to generate N-number of agents. Each agent will have a name, so I create a random name from names and assigned it to class Agent. After I run the model, I want to get the list of my agents name. This is from mesa: import names from mesa import Agent, Model from mesa.time import RandomActivation class Agent(Agent): def __init__(self, name): self.name= names.get_full_name() self.wealth = 1 def step(self): pass class Model(Model): def __init__(self, N): self.num_agents = N self.schedule = RandomActivation(self) for i in range(N): a = MoneyAgent(i) self.schedule.add(a) def step(self

I want to force chrome to render WebGL using software drivers, not hardware. I'm using Ubuntu Linux and I understand that the Mesa GL drivers can be forced to use a software implementation by specifying the environment variable, LIBGL_ALWAYS_SOFTWARE=1 , when launching a program. I confirmed that the driver changes when specifying the env var. bash$ glxinfo | grep -i "opengl" OpenGL vendor string: Intel Open Source Technology Center OpenGL renderer string: Mesa DRI Intel(R) 945GM x86/MMX/SSE2 OpenGL version string: 1.4 Mesa 10.1.3 OpenGL extensions: bash$ LIBGL_ALWAYS_SOFTWARE=1 glxinfo | grep

When I am trying to launch Android virtual device in Android Studio 2.0, it is giving me following error. ERROR: Invalid GPU mode 'mesa', use one of: on off host guest A screen shot is given bellow related to this error: Any help would be greatly appreciated!Thanks..... Go to Virtual device manager, click 'Show on Disk' in the menu of the Virtual device. Open the config.ini file and change the respective line to: hw.gpu.mode=guest Then save the config.ini and then run Virtual device again. It should work. I had the same error and what worked for me was : Open AVD manager as in the screenshot
