Question

前段时间我在我的机器上激活了Windows子系统Linux，但没有多少使用它。现在我知道我可以使用它，这就是为什么我试图在我的WSL上安装gcc / ++ 7并继续遇到问题。

我的想法是download并在this guide之后手动编译：

../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未找到＆＃34;命令＆＃34;。所以我的下一步是通过以下方式安装gcc：

sudo apt install gcc

这有效：

$ gcc --version

然而，当我从上面尝试configure命令时，我得到了：

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 a default linker was specified... no
checking whether a default assembler was specified... no
checking for x86_64-linux-gnu-gcc... x86_64-linux-gnu-gcc
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：

int main() {
    return 42;
}

暗示某些事情似乎被严重打破

$ 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

我甚至可以开始修理这个想法吗？如果这有帮助，我甚至不介意重置整个WSL：/

lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 16.04.3 LTS

Codename:       xenial

更新

在所有这些之前，我尝试安装gcc7 / g ++ / via apt但没有成功：

$ sudo add-apt-repository ppa:jonathonf/gcc-7.1
$ sudo apt-get update
$ sudo apt-get install gcc-7 g++-7

更新2

可悲的是，所提出的方法都没有帮助，我最终还是在努力学习WSL。显然，更严重的事情被打破了。

Answer 1

为什么要编译？您应该能够安装该软件包：

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

请参阅How to install gcc-7 or clang 4.0?

Answer 2

运行以下

@Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
    Bundle bundle = getArguments();
        Double sum = bundle.getDouble("sum_key");
}

或

sudo apt install aptitude
sudo aptitude install gcc-7 g++-7

Answer 3

crt1.o通常作为libdevc依赖项（或类似内容）的一部分提供。我建议使用sudo apt search libc，lib6c，libdev等运行libc-dev或某些类似的变体。安装这些变体修复了我最近遇到的类似问题。

如果失败，请运行find / -iname ctri.o并使用export PATH="[folder]:$PATH"将其显示的文件夹添加到您的路径中，看看是否有帮助。
