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建议在运行之前包含此行，如果SFML安装在非标准路径中（它是）：

$ 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文件在Sublime Text 2中启动程序时，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文件供参考：

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

“Run”变体是我正在使用的变体。如何在游戏在终端外部和Sublime Text 2中启动时自动包含此行？

.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，所以它找不到名为export的程序时会失败 - 因为它是一个内置的shell。

要在shell中运行整个命令（就像手动操作一样），您可以在"shell" : true变体中指定Run（或使用shell_cmd代替{{1} }}）：

cmd

这应该比直接调用{ "name": "Run", "cmd": ["export", "LD_LIBRARY_PATH=/home/dan/SFML-2.3.1/lib", "&&", "./YorickTheSavant"], "shell" : true }更好，我认为你不需要将cmd数组中的条目压缩成一个字符串了。

或者，您也可以尝试使用/bin/sh -c <stuff>键（也找到here）在运行可执行文件之前指定env环境变量：

LD_LIBRARY_PATH

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