Question asked by xin fang on Dec 10, 2018

Hello, I need remote desktop on my imx6q embed device . So I try to cross compile the RealVNC source code . when i building Xvnc after patched xc, exec "make World" . its failed . 


fangxin@fangxin-NV47H:xc$ make World

I hope you checked the configuration parameters in ./config/cf
to see if you need to pass BOOTSTRAPCFLAGS.

I guess ,  I need to modify the Makefile  about the environment CFLAGS  , but i dont know how to do it ?
