使用前，执行命令source /opt/Xilinx/SDK/2019.1/settings64.sh ，导入相关路径，就可以。
xilinxtool$ find -name aarch64-linux-gnu-gcc ./peta/2018.1/tools/linux-i386/aarch64-linux-gnu/bin/aarch64-linux-gnu-gcc ./peta/2018.3/tools/linux-i386/aarch64-linux-gnu/bin/aarch64-linux-gnu-gcc ./peta/2018.2/tools/linux-i386/aarch64-linux-gnu/bin/aarch64-linux-gnu-gcc ./SDK/2018.3/gnu/aarch64/lin/aarch64-linux/bin/aarch64-linux-gnu-gcc ./SDK/2019.1/gnu/aarch64/lin/aarch64-linux/bin/aarch64-linux-gnu-gcc ./SDK/2018.2/gnu/aarch64/lin/aarch64-linux/bin/aarch64-linux-gnu-gcc xilinxtool$ find -name "aarch64*linux*gcc" ./peta/2018.1/tools/linux-i386/aarch64-linux-gnu/bin/aarch64-linux-gnu-gcc ./peta/2018.3/tools/linux-i386/aarch64-linux-gnu/bin/aarch64-linux-gnu-gcc ./peta/2018.2/tools/linux-i386/aarch64-linux-gnu/bin/aarch64-linux-gnu-gcc ./SDK/2018.3/gnu/aarch64/lin/aarch64-linux/bin/aarch64-linux-gnu-gcc ./SDK/2019.1/gnu/aarch64/lin/aarch64-linux/bin/aarch64-linux-gnu-gcc ./SDK/2018.2/gnu/aarch64/lin/aarch64-linux/bin/aarch64-linux-gnu-gcc xilinxtool$
