使用sublime-build时不能运行c++程序，从终端运行时工作正常

Cannot run C++ program when using sublime-build, works fine when running from terminal

本文关键字：终端 运行时 工作 程序 sublime-build 不能 运行 c++ 使用      更新时间：2023-10-16

我正在尝试在Linux/Ubuntu 14.04上运行c++程序

我正在使用SFML库，如果SFML安装在非标准路径(它确实是)，则教程建议在运行之前包含这一行:

$ 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，当尝试在Sublime - Text 2中使用Sublime -build文件启动程序时，我得到以下错误:

[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文件供参考:

    }
]
}

"运行"的变体是我正在使用的。当游戏在终端外启动时，我该如何让这一行自动包含在Sublime Text 2中?

.sublime-build文件中的cmd键指定要运行的程序。第一个值应该是程序，其余的是参数，因此，当它找不到一个名为export的程序时，它就会失败——因为它是一个内置的shell。

要在shell中运行整个命令(就像手动运行一样)，您可以在Run变体中指定"shell" : true(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
}

这应该比直接调用/bin/sh -c <stuff>工作得更好，我不认为你需要将cmd数组中的条目压缩成单个字符串了。

或者，您也可以尝试使用env键(也可以在这里找到)在运行可执行文件之前指定LD_LIBRARY_PATH环境变量:

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