我正在尝试使用硬件制造商提供的工具链交叉编译uclinux。
当我运行make命令时，出现一个我无法理解的错误：
yannick@ubuntu:~/uclinux-dist$ make make -C tools/ucfront make[1]: Entering directory `/home/yannick/uclinux-dist/tools/ucfront' make[1]: `ucfront' is up to date. make[1]: Leaving directory `/home/yannick/uclinux-dist/tools/ucfront' ln -sf /home/yannick/uclinux-dist/tools/ucfront/ucfront tools/ucfront-gcc ln -sf /home/yannick/uclinux-dist/tools/ucfront/ucfront tools/ucfront-g++ make ARCH=arm CROSS_COMPILE=arm-uclinux-elf- -C linux-2.6.x || exit 1 make[1]: arm-uclinux-elf-gcc: Command not found make[1]: Entering directory `/home/yannick/uclinux-dist/linux-2.6.x' CHK include/linux/version.h make[2]: `include/asm-arm/mach-types.h' is up to date.

谢谢 ！！
运行make时的路径值不一定是执行命令时的值。 在你试图编译源文件之前，我会在实际的makefile放置一个echo $PATH 。
这至少会说明在构建过程中是否会改变你的路径。
你还应该在环境变量中加上这个
导出CROSS_COMPILE = arm-uclinux-elf-
