g ++致命错误，无此文件或目录 [英] g++ fatal error no such file or directory

问题描述

所以我正在使用 gvim编辑器在C ++中进行编程，但是当我打开一个在编辑器上的.cpp文件，然后键入:!g++ -std=C++17 file.cpp -o file我收到此错误: 请参阅下面的附件:

So I am using the gvim editor to program in C++, however when I open a .cpp file on the editor then type :!g++ -std=C++17 file.cpp -o file I get this error: See attached file below:

C:\Windows\system32\cmd.exe /c(g++ -std=c++17 file.cpp - o file)
g++: error: file.cpp: No such file or directory
g++: fatal error: no input files
compilation terminated

现在这与vim或我的命令有关吗?

Now is this related to vim, or to my command?

谢谢.

推荐答案

您似乎不幸地使用了gcc-mingw，而gcc-mingw并没有正确配置gnumake(否则:let $CXXFLAGS='-std=c++17 -Wall -Werror' + make %<就足够了).因此，您将需要手动执行一些操作.并且不要将参数错误拼写为g ++.忘了:!{compilername}，这就是我们要在25年前用vi做的事情.与vi不同，vim允许集成编译.

It seems that you're unfortunately using gcc-mingw that doesn't come with gnumake properly configured (:let $CXXFLAGS='-std=c++17 -Wall -Werror'+ make %< would have been enough otherwise). Thus you'll have a do a few things manually. And don't misspell the parameters to g++. And forget :!{compilername}, this is want we had to do 25 years ago with vi. Unlike vi, vim permits to integrate compilation.

" to do once
:let &makeprg='g++ -std=c++17 -Wall -Werror % -o %<'

" to execute each time to compile
:make
:copen

" to navigate the errors
:cc      " jump to error under cursor
:cnext   " jump to next error
:cprev   " jump to previous error
:cclose  " close the quickfix window

-> :h quickfix

这不应从错误的目录执行g ++.如果还是这样，请运行:cd %:h.

This shouldn't execute g++ from the wrong directory. If this still does, run :cd %:h.

执行应与:./%一起使用.

如果您希望为此使用热键...

And if you wish to have hot keys for that...

nnoremap <silent> <F7>   :<c-u>update<cr>:make<cr>
nnoremap <silent> <C-F5> :<c-u>./%<cr>

nnoremap <silent> <F3>   :<c-u>cnext<cr>
nnoremap <silent> <S-F3> :<c-u>cprev<cr>

仅在出现错误时自动打开快速修复程序窗口，或者仅在没有错误时才自动执行结果，这需要更多的工作.

Automatically opening the quickfix windows only if there are errors or executing the result only if there are no errors requires a little more work.
