uclinux编译错误

Question

我正在尝试使用硬件制造商提供的工具链来交叉编译uclinux。

当我运行make命令时，出现了一个我无法理解的错误：

yannick@ubuntu:~/uclinux-dist$ make

谢谢！

Answer 1

运行make时路径的值不是必然命令执行时的内容。在您尝试编译源文件之前，我会在实际echo $PATH中放置一个makefile。

这至少可以说明在构建过程中是否有什么东西在改变你的路径。

Answer 2

你还应该在环境变量

中添加它

跨工具的路径

导出CROSS_COMPILE = arm-uclinux-elf-
