Ubuntu installed the tool chain of nuc980, configured the environment variables, and entered the command to verify whether it is correct. The error message: command not found.
arm-nuvoton-linux-uclibceabi-gcc -v
Check the official document < NUC980 Linux BSP User Manual >. The manual information indicates that libc6-dev is required for the cross-compilation tool chain, as follows:
To install the software on Ubuntu, the instructions are:
sudo apt install libc6-dev
Enter the command again to verify, and find that an error message is still reported: command not found. Check the environment variables, the environment variables are also correct. Solution: Enter the command to reboot.
rebootAfter restarting, enter the command again:
arm-nuvoton-linux-uclibceabi-gcc -vIt can be seen that the version information of the configured specified tool chain can be obtained. The final result is as follows:
xyz@ubuntu:~$ arm-nuvoton-linux-uclibceabi-gcc -v
