是否用了 -j2 -j4 -j8 开启了并发？错误信息可能被其它 job 掩盖了
去掉这个选项试试

谢谢

用的命令是
make O=build -j$(nproc) ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- uImage modules

现在把 -j$(nproc) 去掉了，编译非常慢

谢谢，现在提示mkimage: command not found
网上搜到说在uboot/tools目录下？看了一下内核源代码里没有这个目录
究竟怎么安装这个工具呢？

在搞全志的开发板？

那是 u-boot 的源代码，编译 u-boot 了么？找出来放到 $PATH 里

直接从软件源安装 u-boot-tools

谢谢，成功了。
