在OS X上交叉编译binutils

时间:2013-12-02 20:41:43

标签: gcc cross-compiling toolchain binutils

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:

gcc -DHAVE_CONFIG_H -I. -I../../binutils-2.23.2/binutils  -I. -I../../binutils-2.23.2/binutils -I../bfd -I../../binutils-2.23.2/binutils/../bfd -I../../binutils-2.23.2/binutils/../include -I./../intl -DLOCALEDIR="\"/usr/local/arm/share/locale\"" -Dbin_dummy_emulation=bin_vanilla_emulation  -W -Wall -Wstrict-prototypes -Wmissing-prototypes -Wshadow -Werror -g -O2 -MT readelf.o -MD -MP -MF .deps/readelf.Tpo -c -o readelf.o ../../binutils-2.23.2/binutils/readelf.c

make[3]: *** [all-recursive] Error 1
make[2]: *** [all] Error 2

错误的原因是什么?如何解决?


更新1

binutils更新为2.24,错误已更改为

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。

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:
