[英]I can't build C++ with visual studio code
我想用C ++編譯我的“ hello world”,但我不能。 我使用Visual Studio代碼,這是我的代碼。
當我嘗試構建cpp時,錯誤是:
鐺:錯誤:沒有這樣的文件或目錄:'/ Users / a1 / C ++ / first'
我的文件是“ /Users/a1/C++/first.cpp”
這適用於macOS,High Sierra 10.14和Visual Studio代碼。
我安裝了C / C ++,但現在無法構建C ++。
#include "stadfx.h"
#include < iostream >
int _tmain(int argc, _TCHAR* argv[]) {
std::cout <<"Hello, World" <<std::endl;
return 0;
}
執行任務:g ++ /Users/a1/C++/first.cpp -o -g / Users / a1 / C ++ / first <
鐺:錯誤:沒有這樣的文件或目錄:'/ Users / a1 / C ++ / first'코드로세스가코드1(으)로종료되었습니다。
這是我的“ tasks.json”

-o選項需要一個文件名,該文件名應緊接在“ -o”之后。 您已將“ -g”作為文件名。 然后命令以要編譯的文件結束。 在您的情況下,“第一個”(不存在)。
嘗試將json文件中的順序移動到類似以下內容:
"args": [
"-g",
"-o",
"${fileDirname}/${fileBasenameNoExtension}",
"${file}"
],
