project error : cannot run target compiler ' aarch64-linux-gnu-g++"

This error message indicates that the target compiler for the AArch64 architecture is not installed or not properly configured on your system.

To fix this error, you need to install the AArch64 cross-compiler toolchain for your system. You can do this by running the following command in your terminal:

sudo apt-get install gcc-aarch64-linux-gnu

If you are using a different Linux distribution or operating system, you may need to install the AArch64 cross-compiler toolchain from a different package repository or source.

Once you have installed the AArch64 cross-compiler toolchain, you should be able to compile your project for the AArch64 architecture without encountering this error.
