c++ - 使用 sublime-build 时无法运行 C++ 程序，从终端运行时工作正常

Question

我正在尝试在 Linux/Ubuntu 14.04 上运行 C++ 程序

我正在使用 SFML 库，tutorial如果 SFML 安装在非标准路径(它是)中，建议在运行之前包含此行:

$ export LD_LIBRARY_PATH=<sfml-install-path>/lib

我可以使用以下输入从终端运行程序:

$ export LD_LIBRARY_PATH=/home/dan/SFML-2.3.1/lib && ./YorickTheSavant

但是，当尝试使用 sublime-build 在 Sublime Text 2 中启动程序时文件，我收到以下错误:

[Errno 2] No such file or directory
[cmd:  [u'export', u'LD_LIBRARY_PATH=/home/dan/SFML-2.3.1/lib', u'&&', u'./YorickTheSavant']]
[dir:  /home/dan/yorickthesavant]
[path: /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/home/dan/.rvm/bin]
[Finished]

这是我的 sublime-build 文件供引用:

        "cmd": ["export", "LD_LIBRARY_PATH=/home/dan/SFML-2.3.1/lib", "&&", "./YorickTheSavant"]
    }
]
}

“运行”变体是我正在使用的变体。当游戏在终端外和 Sublime Text 2 中启动时，我该如何做到这一行自动包含在内？

Answer 1

cmd .sublime-build 文件中的键指定要运行的程序。 第一个值应该是程序，其余的是参数， 所以当它找不到名为 export 的程序时它会失败- 因为它是一个内置的 shell。

要在 shell 中运行整个命令(就像您手动执行时那样)，您可以指定 "shell" : true在你的Run变体(或使用 shell_cmd 而不是 cmd ):

{
    "name": "Run",
    "cmd": ["export", "LD_LIBRARY_PATH=/home/dan/SFML-2.3.1/lib", "&&", "./YorickTheSavant"],
    "shell" : true
}

这应该比调用 /bin/sh -c <stuff> 效果更好直接，我认为您不再需要将 cmd 数组中的条目压缩为单个字符串。

或者，您也可以尝试使用 env键(也找到了 here )来指定 LD_LIBRARY_PATH运行可执行文件之前的环境变量:

{
    "name": "Run",
    "cmd": ["./YorickTheSavant"],
    "env" : { "LD_LIBRARY_PATH" : "/home/dan/SFML-2.3.1/lib" }
}
