When trying to build a external toolchain for the openwrt image developed for raspberry pi.
Toolchain directory '/opt/cross/aarch64-unknown-linux-gnu' does not exist. make[3]: * [/home/source/build_dir/toolchain-aarch64-unknown-linux-gnu/wrapper-1/.prepared] Error 1 make[2]: [toolchain/wrapper/compile] Error 2 make[1]: [/home/source/staging_dir/toolchain-aarch64-unknown-linux-gnu/stamp/.toolchain_compile] Error 2 make: * [world] Error 2
How to bring a toolchain in the openwrt output image in any path like the above (/opt/cross/aarch64-unknown-linux-gnu).
