我们在对讲的时候，视频通过ffmpeg解码之后，要用opengl来渲染，在调用glGenTextures的时候获取的都是0。
请问如果我要使用opengl，内核里面还需要在添加什么配置吗？
有没有相关资源可以支持下。谢谢。
你是想用内部的3D加速模块，还是不用的？E2E论坛上有个帖子讨论Building OpenGL on the AM335x EVM，参考一下：
http://e2e.ti.com/support/arm/sitara_arm/f/791/t/342126
执行make BUILD=release OMAPES=8.x all_km的时候报错了：
1：make: *** /home/lltang/Graphics_SDK_5_01_01_02/graphics/Graphics_SDK_5_01_01_02/GFX_Linux_KM: 没有那个文件或目录。 停止。
2：/home/lltang/Graphics_SDK_5_01_01_02/GFX_Linux_KM/services4/srvkm/env/linux/module.c:51:42: fatal error: linux/platform_data/sgx-omap.h: 没有那个文件或目录
你有正常安装过graphic SDK吗？应该是有这个目录和文件的。如果有的话，请注意路径的设置是否正确。
安装过的。需要copy什么文件么？
1， 修改了Rules.make 的GFX_KERNMOD_SRCPATH
这个问题好了。
2，我注释了头文件，编译过了。
不过出现下面问题。
按照网上我重新编译了，发现如下问题。请问可能是什么原因？
