前段时间我在我的电脑上启用了Windows子系统Linux，但没有多少使用。现在我有一个想法，那就是在WSL上安装gcc/++ 7并一直遇到问题。
../gcc/configure -v --build=x86_64-linux-gnu --host=x86_64-linux-gnu --target=x86_64-linux-gnu --prefix=${HOME}/software/gcc-7.3.0/installDir --enable-checking=release --enable-languages=c,c++,fortran --disable-multilib
这导致了以下错误：
checking build system type... x86_64-pc-linux-gnu
checking host system type... x86_64-pc-linux-gnu
checking target system type... x86_64-pc-linux-gnu

checking for cl.exe... no
configure: error: in `$HOME/software/gcc-7.3.0/build':
configure: error: no acceptable C compiler found in $PATH
See `config.log' for more details.
显然，没有安装gcc。至少gcc和cc命令都提示“未找到命令”。因此，接下来我通过以下方式安装了gcc：
sudo apt install gcc
这个有效：
$ gcc --version

然而，当我尝试上述的配置命令时，出现了以下错误：
checking build system type... x86_64-pc-linux-gnu
checking host system type... x86_64-pc-linux-gnu
checking target system type... x86_64-pc-linux-gnu

checking for C compiler default output file name...
configure: error: in `/home/seriously-ubuntu/software/gcc-7.3.0/build':
configure: error: C compiler cannot create executables
see `config.log' for more details.
于是我试图手动编译一个简单的C程序:
int main() {
return 42;
}
这表明某些东西似乎严重出错了。
$ gcc foo.c
/usr/bin/ld: cannot find crt1.o: No such file or directory
/usr/bin/ld: cannot find crti.o: No such file or directory
/usr/bin/ld: cannot find -lc
/usr/bin/ld: cannot find crtn.o: No such file or directory
collect2: error: ld returned 1 exit status
有什么建议可以帮助我修复这个问题吗？如果重新设置整个WSL有所帮助，我也不介意 :/
lsb_release -a

更新:
在进行以下操作之前，我尝试使用apt安装gcc7 / g ++，但未成功：
$ sudo add-apt-repository ppa:jonathonf/gcc-7.1
$ sudo apt-get update
$ sudo apt-get install gcc-7 g++-7

更新2
遗憾的是，没有任何建议的方法能够解决问题，我最终选择强制重置WSL。显然，有更严重的故障发生了。
