Fedora 15 上的 OpenGL
我正在尝试使用 OpenGL 进行编程。
所以编写了一个测试程序调用 t_gl1.cpp
我用
$ g++ t_gl1.cpp -lglut -lGL -lGLU -o t_gl1
成功构建了它,没有任何错误。
但是,如果我尝试运行它,我会得到
freeglut (./t_gl1): ERROR: Internal error in function fgOpenWindow X 请求失败错误:BadWindow(窗口参数无效) 失败请求的主要操作码:4 (X_DestroyWindow) 失败请求中的资源 ID:0x0 失败请求的序列号:26 输出流中的当前序列号:29
有谁知道发生了什么事吗?
这是代码,在Windows和Mac上测试过,没有问题。但无法在 Fedora 和 Ubuntu 上运行

I am trying to program in OpenGL.
so wrote a test program call t_gl1.cpp
I built it successfully with
$ g++ t_gl1.cpp -lglut -lGL -lGLU -o t_gl1
No any error.
However, if I try to run it, I got
freeglut (./t_gl1): ERROR: Internal error in function fgOpenWindow
X Error of failed request: BadWindow (invalid Window parameter)
Major opcode of failed request: 4 (X_DestroyWindow)
Resource id in failed request: 0x0

Does any one know what is going on?

我同意塔隆米斯的观点。
这是因为 Nvidia 的问题。我找不到在 Fedora 15 上安装 Nvidia 开发人员驱动程序的官方方法。所以我使用了 rpmfusion。驱动程序运行了,我就可以运行CUDA了。只有 GLX 相关的东西才被搞乱。然而,它也搞乱了 Gnome 3。
所以我转而使用 Arch Linux。有了一个干净的开始,安装 Nvida 并根据 ArchWiki 安装 Xorg。然后安装 Gnome。令人惊奇的是,OpenGL 竟然可以工作。我猜Arch repo 中的驱动程序不是开发人员的驱动程序。也许只是用于显示驱动程序。然而,CUDA 可以工作。
我对此很高兴。希望这对那些想要在 Linux 上运行 CUDA 和 OpenGL 的人有所帮助。
谢谢,
阿尔弗雷德
I aggreed with talonmies.
It was because of the Nvidia problem. I could't find a official way to install Nvidia's developer's driver on Fedora 15. So I used rpmfusion. The driver runs and I can run CUDA. Only GLX related stuff are messed up. However, it also messed up Gnome 3.
So I switched to Arch Linux. With a much clean start, install Nvida and install Xorg according to the ArchWiki. And then install Gnome. Amazingly, OpenGL works. I guess the driver in Arch repo is not the developer's driver. Maybe just for display driver. However, CUDA works.
I am glad with that. And hopefully this will be helpful to some one else who want to run CUDA and OpenGL on Linux.
Thanks,
Alfred
代码没有任何问题。我可以在正确配置的 64 位 Linux 系统上使用 NVIDIA 版本 280.13 驱动程序成功编译并运行它。您有驱动程序或 X11 驱动程序安装或配置问题。此问题不需要编程帮助。
There is nothing wrong with the code. I can successfully compile and run it on a properly configured 64 bit linux system with NVIDIA release 280.13 drivers. You have a driver or X11 driver installation or configuration problem. There is no programming help required for this question.
既然您标记了这个问题
cuda
,我将假设您正在运行 NVidia 硬件。尝试安装一些驱动程序。
Since you tagged this question
cuda
I'm going to assume you're running NVidia hardware.Try installing some drivers.
