When I independently compiled imx-v4l2-overlay. c, the cross compiler reported that the mxcfb. h file could not be found.
This file can be found in the Linux source code, but it cannot be found in the installation location of the cross-compilation tool chain. The compiler defaults to include pointing to the cross-compilation tool chain.
What should I do?
What is the difference between imxfb. h and fb. h?
What is the difference between imxfb. h and fb. h?
=>The frame buffer drivers depend heavily on four data structures. These structures are declared in include/linux/fb.h. They are fb_info, fb_var_screeninfo, fb_fix_screeninfo and fb_monospecs. The last three can be made available to and from userland.
