在 windows 子系统上为 linux 安装 g++ [英] Installing g++ on windows subsystem for linux
问题描述
不久前，我在我的机器上激活了适用于 Linux 的 Windows 子系统，但并没有经常使用它.现在我知道我可以用它做什么，这就是为什么我试图在我的 WSL 上安装 gcc/++ 7 并不断遇到问题.
A while back I activated Windows Subsystem for Linux on my machine but didn't use it much. Now I have an idea what I could use it for and that is why I'm trying to install gcc/++ 7 on my WSL and keep running into problems.
我的想法是下载并按照
../gcc/configure -v --build=x86_64-linux-gnu --host=x86_64-linux-gnu --target=x86_64-linux-gnu --prefix=${HOME}/software/gcc-7.3.0/installDir --enable-checking=release --enable-languages=c,c++,fortran --disable-multilib
这导致了以下错误:
checking build system type... x86_64-pc-linux-gnu
checking host system type... x86_64-pc-linux-gnu
checking target system type... x86_64-pc-linux-gnu
checking LIBRARY_PATH variable... ok
checking GCC_EXEC_PREFIX variable... ok
checking whether to place generated files in the source directory... no
checking whether a default linker was specified... no
checking whether a default assembler was specified... no
checking for x86_64-linux-gnu-gcc... no
checking for gcc... no
checking for x86_64-linux-gnu-cc... no
checking for cc... no
checking for x86_64-linux-gnu-cl.exe... no
checking for cl.exe... no
configure: error: in `$HOME/software/gcc-7.3.0/build':
configure: error: no acceptable C compiler found in $PATH
See `config.log' for more details.
显然，根本没有安装(?)gcc.至少 gcc 和 cc 产生找不到命令".所以我的下一步是通过以下方式安装 gcc:
Apparently, there was no(?) gcc installed at all. At least gcc and cc yielded "command not found". So my next step was installing gcc via:
sudo apt install gcc
这有效:
$ gcc --version

然而，当我从上面尝试配置命令时:
However when trying the configure command from above I got:
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 LIBRARY_PATH variable... ok

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.
所以我尝试手工编译一个简单的c程序:
So I tried to compile a simple c program by hand:
int main() {
return 42;
}
暗示某物似乎严重损坏
$ 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
我什至可以开始修复它的任何想法?如果这有帮助，我什至不介意重置整个 WSL:/
Any Ideas where I can even start to repair this? I wouldn't even mind reseting the whole WSL if this helps :/

在这一切之前，我尝试通过 apt 安装 gcc7/g++/没有成功:
Before all of this I tried installing gcc7 / g++/ via apt without success:
$ sudo add-apt-repository ppa:jonathonf/gcc-7.1
$ sudo apt-get update
$ sudo apt-get install gcc-7 g++-7

可悲的是，所有建议的方法都没有帮助，我最终破坏了 WSL.显然，更严重的东西被破坏了.
Sadly none of the suggested ways helped and I ended up nuking the WSL. Apparently, something more severe was broken.
推荐答案
为什么要编译?您应该能够安装该软件包:
Why compiling? You should be able to install the package:
sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt update
sudo apt install g++-7 -y
验证使用:
gcc-7 --version
