is very fast, builtin toolchains can not keep up, to reduce the maintaining pressure, external toolchain feature is added. for example, ARM64/virt, CCVER and CCPATH has been added for it. List available the external toolchain: 1 $ make gcc Switch compiler version if exists, for example: 1 $ make gcc-switch CCORI=internal GCC=4.7 2 3 $ make gcc-switch CCORI=linaro If not external toolchain there, the the builtin will be used back. If no builtin toolchain exists, please must use this external toolchain feature, currently, aarch64, arm, riscv, mipsel, ppc, i386, x86_64 support such feature. 36 欢迎加入

speed is slower. To overcome this, you can cross compile your code on a Linux machine using a toolchain; the compiling speed is much faster. Native Compilation Follow these steps to update the package compilation. Moxa Industrial Linux 3.0 (Debian 11) Manual for Arm-based Computers 92 The toolchain will need about 300 MB of hard disk space on your PC. To cross compile your code, do the following: again. user@Linux:~$ apt update 6. Download the toolchain file from apt server (all Moxa UC series computers use the official Debian toolchain). user@Linux:~$ apt install crossbuild-essential-armhf
