配置qnx6.6 VM 中 screen 环境变量
根据 Screen Graphics Subsystem Developer’s Guide 总结。
- 停止 screen 进程： slay screen
- 确保 screen 进程已停止： pidin ar 查看当前运行进程
- 设置环境变量：GRAPHICS_ROOT
export GRAPHICS_ROOT=/usr/lib/graphics/vmware
设置环境变量：LD_LIBRARY_PATH
export LD_LIBRARY_PATH=/usr/lib:/lib:/lib/dll:$GRAPHICS_ROOT:$LD_LIBRARY_PATH
运行 screen ： /sbin/screen
正常的话，屏幕会变大，全黑，鼠标出现。 不能再进行命令行操作。需要用SDP中的Terminal 连接qnx
如何用Terminal连接qnx
（1）在虚拟机的/etc目录中找到inetd.conf这个文件，打开，将一下四行的“#”去掉
#ftp stream tcp nowait root /usr/sbin/ftpd in.ftpd -l
#telnet stream tcp nowait root /usr/sbin/telnetd in.telnetd
#ftp stream tcp6 nowait root /usr/sbin/ftpd ftpd -ll
#telnet stream tcp6 nowait root /usr/sbin/telnetd telnetd
（2）执行命令 /usr/sbin/inetd &
（3）在qnx IDE打开Terminal：Window->show view->other->Terminal
（4）Terminal的选项卡里面，设置connection type为Telnet，之后在host输入虚拟机IP，点击确定即可。
测试egl
运行/usr/bin/egl-configs 出现如下信息，说明egl可以跑了
# /usr/bin/egl-configs
EGL_VENDOR = QNX Software Systems
EGL_VERSION = 1.4
EGL_CLIENT_APIS = OpenGL_ES
EGL_EXTENSIONS = EGL_EXT_swap_regions EGL_KHR_image
