Error when compiling module module in Linux driver [Copy link]

When writing a driver, the compilation module reported such an error. I have been looking for the reason for a day and don’t know where the problem is. Can any big guy help me?

To summarize this problem, as shown in the picture, the problem is the lack of Module.symvers file. For security reasons, some function calls in the Linux kernel are stored in "third-party files", and Module.symvers is this third-party file, so it is shown that there are so many functions not found. The bottom line is that there is no such file. If you want to have this file, when compiling your own module, first use make modules to compile the kernel module, so that this file will be generated and the problem will be solved.

The compilation environment is not set up. Refer to install SDK , source SDK/environment-setup-cortexa7t2hf-neon-vfpv4-ostl-linux-gnueabi
