手臂：./busybox：第 1 行：语法错误：意外单词（预期“）”）答案

【问题描述】：

我正在设置一个专门用于 armv7l 交叉编译的虚拟机。作为测试，我决定编译busybox，虽然交叉编译本身工作正常，但在将生成的二进制文件上传到具有正确架构的路由器时，二进制文件抱怨./busybox: line 1: syntax error: unexpected word (expecting ")")

在为 x86 编译时我没有遇到这个问题，因此我认为问题出在我的构建环境上。

它基于ubuntu18服务器，我已经安装了这些包：

gcc-arm-linux-gnueabi
binutils-arm-linux-gnueabi
libncurses5-dev
gawk
build-essentials
make

我的构建脚本：

export ac_cv_linux_vers=2
export CC=/usr/local/arm-2011.09/bin/arm-none-linux-gnueabi-gcc
export GCC=/usr/local/arm-2011.09/bin/arm-none-linux-gnueabi-gcc
export CXX=/usr/local/arm-2011.09/bin/arm-none-linux-gnueabi-g++
export CPP=/usr/local/arm-2011.09/bin/arm-none-linux-gnueabi-cpp
export LD=/usr/local/arm-2011.09/bin/arm-none-linux-gnueabi-ld

export AS=/usr/local/arm-2011.09/bin/arm-none-linux-gnueabi-as
export NM=/usr/local/arm-2011.09/bin/arm-none-linux-gnueabi-nm
export RANLIB=/usr/local/arm-2011.09/arm-none-linux-gnueabi/bin/ranlib
export CC1=/usr/local/arm-2011.09/libexec/gcc/arm-none-linux-gnueabi/4.6.1/cc1
export PATH=/usr/local/arm-2011.09/bin:/usr/local/arm-2011.09/:/usr/local/arm-2011.09/lib:/usr/local/arm-2011.09/libexec/gcc/arm-none-linux-gnueabi/4.6.1:$PATH
export ac_cv_func_getpgrp_void=yes
export ac_cv_func_setpgrp_void=yes
export LDFLAGS="-static"
export CFLAGS="-Os -s"
# I already did make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- 
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi-
make install

我的构建过程有什么明显的缺陷吗？

我尝试运行busybox的平台：

标签： build arm cross-compiling busybox armv7

【解决方案1】：

解决了。原来我的make menuconfig不完整。

Busybox Settings -> Build Options -> Build Busybox as a static binary (no shared libs)
Busybox Settings -> Build Options -> Cross compiler prefix -> Set this option equal to "arm-linux-gnueabi-"
Busybox Settings -> Installation Options -> Don't use /usr -> Enable
Linux Module Utilities -> () Default directory containing modules -> blank

之后，构建脚本生成的二进制文件按预期工作
