LibGCC编译因错误而失败：无法计算目标文件的后缀：无法编译

问题描述

当我尝试按照以下说明安装gcc交叉编译器时：

sudo apt update
sudo apt -y install curl build-essential m4 libgmp3-dev libmpc-dev libmpfr-dev

# install gmp 6.2.0
curl --output gmp-6.2.0.tar.bz2 https://ftp.gnu.org/gnu/gmp/gmp-6.2.0.tar.bz2
tar -xvf gmp-6.2.0.tar.bz2
cd gmp-6.2.0
./configure --prefix=/usr/local/cc
make check && sudo make install
cd ..

# install mpfr
curl --output mpfr-4.1.0.tar.bz2 https://ftp.gnu.org/gnu/mpfr/mpfr-4.1.0.tar.bz2
tar -xvf mpfr-4.1.0.tar.bz2
cd mpfr-4.1.0
./configure --prefix=/usr/local/cc
make check && sudo make install
cd ..

# install mpc
curl --output mpc-1.2.0.tar.gz https://ftp.gnu.org/gnu/mpc/mpc-1.2.0.tar.gz
tar -xvf mpc-1.2.0.tar.gz
cd mpc-1.2.0
./configure --prefix=/usr/local/cc
make check && sudo make install
cd ..

# install gcc
curl --output gcc-10.2.0.tar.xz https://ftp.gnu.org/gnu/gcc/gcc-10.2.0/gcc-10.2.0.tar.xz
tar -xvf gcc-10.2.0.tar.xz
mkdir gcc-make-tmp
cd gcc-make-tmp
../gcc-10.2.0/configure\
    --target=x86_64-elf\
    --prefix=/usr/local/cc\
    --disable-nls\
    --enable-languages=c\
    --without-headers\
    --with-gmp=/usr/local/cc\
    --with-mpfr=/usr/local/cc\
    --with-mpc=/usr/local/cc\
    --with-headers=/usr/include\
    --with-headers=/usr/include/x86_64-linux-gnu

make all-gcc && make install-gcc
make all-target-libgcc && make install-target-libgcc

但是make all-target-libgcc失败，并出现错误：configure: error: cannot compute suffix of object files: cannot compile。

config.log：

This file contains any messages produced by compilers while
running configure,to aid debugging if configure makes a mistake.

It was created by GNU C Runtime Library configure 1.0,which was
generated by GNU Autoconf 2.69.  Invocation command line was

环境

• WSL2上的Ubuntu 20.04

有关StackOverflow的常见问题

• Gcc compilation "cannot compute suffix of object files: cannot compile"
• Compilng libgcc xgcc error
• compiling gcc,configure: error: cannot compute suffix of object files: cannot compile

解决方法

已解决

• 使用--target=x86_64-elf选项从源代码手动构建binutils。

仅此而已。
