TI中文支持网移植的时候基本用到的库都是TI 官方SDK0301里面的库，不同的只是自己重新编译wayland、weston 。
在运行自己编译的库的时候就运行不起来提示如下：

但是我只要把gl-renderer.so这个库替换成SDK0301 里面提供的就可以运行成功，其他的库什么都没变

启动的方式是 ：启动GPU
unset WAYLAND_DISPLAY
weston –tty=1
gl-renderer.so 是编译weston 时候生成的，是不是在编译weston的时候再官方的交叉编译的时候需要链接上一些TI自己的GPU相关的驱动库？？ 求解
fa linag：
还是说在编译weston 的时候需要一些配置项？？
fa linag：
问题已经解决

遇到同样的错误，使用的是最新版的ti-processor-sdk-linux-am335x-evm-04.01.00.06-Linux-x86-Install.bin里面的默认文件系统， 能说一下解决思路么？
fa linag：
回复 Touch Tsou:
你看清楚你的第一个报错是报的failed to choose EGL config 这个错误么？
fa linag：
回复 Touch Tsou:
如果是的话，你要重新编译你的weston ,修改源码里面读取返回的EGL config 配置项相关的数组值，在gl-renderer.c 里面，我发现他读取回来的值不成功，返回的是0 值。
Segmentation fault：
回复 fa linag:
你好，因为ti提供的Weston版本过旧，在运行Qt时存在一些问题，所以我同样是使用ti 官方SDK0301里面的库，来编译wayland,weston ,我的weston版本为2.0 从buildroot中获取的，在加载gl-renderer.so发生和你同样的错误：failed to choose EGL config，想问一下该如何修改源码里面读取返回的EGL config 配置项相关的数组值，非常期待你的回答

同问
Segmentation fault：
回复 fa linag:
按照你提供的方法，现在已经成功运行起来Weston-2.0，非常感谢。 我将config_index改为6，此时RGBA输出值为5 6 5 0。使用TI 原版文件系统 RGBA输出值为8 8 8 8，所以对于config_index的值和RGBA值的对应关系不是很明白。
fa linag：
回复 Segmentation fault:
对的，是5650，上边提到的8880写错了，这个我具体也没有了解的很清楚，应该是RGBA四种颜色位数据，TI官方的8888 运行起来显示各方面也没发现有什么错误，但是我之前试过如果选用其他的配置的话屏幕显示会出现错误。
