-edit- похоже, что проблема с путем и невозможностью найти его папку / папку.Несмотря на то, что g ++ находится в этом каталоге bin.
Я пытаюсь запустить g ++ на окнах в моем приложении, но я получаю ошибку ниже.Как мне это исправить?примечание стороны, я могу сделать g++ dummy.cpp в приглашении без проблем.
args -o file.exe -x c++ -
stdout
: CreateProcess: No such file or directory
-edit- мой код ...
