在BeagleBone Black上构建gcc失败了

Question

问题

我正在尝试在BeagleBone Black上构建一个交叉编译器,以便从ARM编译为x86.这样做的目的是使用我手头上的低功耗BeagleBone Black作为构建服务器.它已经可以通过mingw-w64为windows编译,但我还需要它来编译Linux x86系统的代码.

但是,当我尝试在BeagleBone Black上编译gcc时,我收到以下错误:

/bin/bash ./libtool --tag=CC   --mode=compile gcc -DHAVE_CONFIG_H -I. -I../../gcc-4.6.3/gmp -D__GMP_WITHIN_GMP    -g -O2 -c -o mpn/div_qr_1n_pi1.lo mpn/div_qr_1n_pi1.c

我知道拇指与ARM有关,但我大部分都不知道为什么这不起作用.我做错了什么？

以下是我尝试创建交叉编译器时所采取的步骤.这是我尝试制作交叉编译器的第一次尝试,因此大部分信息来自几个网页和手册.

采取的步骤

为了创建交叉编译器,我下载了以下包:

1. 的binutils-2.24
2. GMP-6.0.0a
3. MPFR-3.1.2
4. MPC-1.0.2
5. GCC-4.6.3
6. Linux的3.15.3
7. 的glibc-2.19

这些都被解压缩到$ HOME目录中.

从那里我设置了以下bash环境变量.

export PREFIX="$HOME/cross_compiler/x86_64"
export TARGET="x86_64-linux-gnu"
export PATH="$PREFIX/bin:$PATH"

然后我继续配置,构建和安装binutils.

mkdir -p $HOME/builds/binutils
cd $HOME/builds/binutils
../../binutils-2.24/configure --target=$TARGET --prefix="$PREFIX" --disable-nls --disable-werror
make
make install

Binutils构建没有任何错误,所以我继续构建gcc.首先,我将所有附加内容移动到gcc目录中.

mv $HOME/gmp-6.0.0a $HOME/gcc-4.6.3/gmp
mv $HOME/mpfr-3.1.2 $HOME/gcc-4.6.3/mpfr
mv $HOME/mpc-1.0.2 $HOME/gcc-4.6.3/mpc

我然后配置,没有任何错误,并尝试构建gcc.

mkdir -p $HOME/builds/gcc
cd $HOME/builds/gcc
../../gcc-4.6.3/configure --target=$TARGET --prefix="$PREFIX" --disable-nls --enable-languages=c,c++ --enable-shared --with-multilib-list=m32,m64 --enable-threads=posix --enable-tls --without-headers
make

这会产生以下错误:

/bin/bash ./libtool --tag=CC   --mode=compile gcc -DHAVE_CONFIG_H -I. -I../../gcc-4.6.3/gmp -D__GMP_WITHIN_GMP    -g -O2 -c -o mpn/div_qr_1n_pi1.lo mpn/div_qr_1n_pi1.c

我建议使用现有的工具链生成框架之一：buildroot或crosstool-NG ，而不是尝试手动构建交叉编译器。您需要使用 apt-get 在您的 BBB 上安装一些依赖项，但除此之外，这只是配置问题；制作。
