c - 使用交叉编译器运行 Makefile 时出错

Question

我的 Makefile 是

obj-m := hello.o
PWD := $(shell pwd)
KERNELDIR := /lib/modules/4.4.0-130-generic/build#$(shell uname -r)/build/
default:
        make -C $(KERNELDIR) M=$(PWD) #ARCH=$(ARCH) CROSS_COMPILE=$(COMPILER) modules
clean:
        make -C $(KERNELDIR) M=$(PWD) #ARCH=$(ARCH) clean

我想用交叉编译器编译它。我正在使用

编译它

 make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi-

它抛出错误:

satya@satya-dev:~/Test/kernal$ make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi-
make -C /lib/modules/4.4.0-130-generic/build M=/home/satya/Test/kernal #ARCH=arm CROSS_COMPILE= modules

在论坛搜索时提到编译器是32位的，但是我的编译器是64位的。

satya@satya-dev:~/Test/kernal$ uname -m
x86_64

连gcc都更新了一个。

satya@satya-dev:~/Test/kernal$ gcc -v

有什么编译建议吗？

Answer 1

When search in forum for it is mentioned that compiler is 32 bit, but my compiler is 64 bit.

satya@satya-dev:~/Test/kernal$ uname -m
x86_64

您正在运行的系统的体系结构与您的编译器没有任何关系。除此之外，您正在交叉编译(或尝试这样做)，因此您的默认编译器也不相关。

错误信息其实很明显:

/bin/sh: arm-none-linux-gnueabi-gcc: command not found

因此，您只是没有安装用于 arm 的交叉编译器，至少不在您的搜索路径中。
