我正在尝试在OS X Mavericks上创建一个Linux Arm工具链。我在/usr/local/gcc-4.8.1-for-linux64/bin/
中有GCC 4.8.1二进制文件,这是我用来为binutils生成配置脚本的命令:
$ ../binutils-2.23.2/configure --target=arm-unknown-linux --prefix=$PREFIX --bindir=/usr/local/gcc-4.8.1-for-linux64/bin/
运行make all
时出现此错误:

错误的原因是什么?如何解决?
将binutils

使用更高版本的binutils。这种事情已在多个地方修复。版本2.24刚刚问世。
更高版本的binutils中的修复如下所示:
fputs (&" "[n], stdout);
我认为你Mac上的“gcc”确实是“铿锵”的。因为这个原因,当我开始自己编译ELLCC时,我不得不在基于ELLCC cross tool project的clang中更新binutils。

我有更新1 的答案:
这些类型正在干扰OSX中内置的类型。您需要将此修补程序应用于glibc源中的 types.h 。

我使用的是eglibc,因此我的类型位于此处:
