使用sublime-build時無法運行C ++程序，從終端運行時可以正常工作

Question

我正在嘗試在Linux / Ubuntu 14.04上運行C ++程序

我正在使用SFML庫，如果SFML安裝在非標准路徑中（本來是），則該教程建議在運行之前包括以下行：

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

我可以使用以下輸入從終端運行程序：

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

但是，當嘗試使用sublime-build文件在Sublime Text 2中啟動程序時，出現以下錯誤：

[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]

這是我的崇高構建文件供參考：

    {

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

我正在使用“運行”變體。 我如何做到這一點，以便在終端之外啟動游戲並在Sublime Text 2中自動添加該行？

Answer 1

.sublime-build文件中的cmd密鑰指定要運行的程序。 第一個值應該是程序，其余的是參數，因此當它找不到名為export的程序時會失敗-因為它是內置的shell。

要在shell中運行整個命令（就像手動執行操作一樣），可以在Run變體中指定"shell" : true （或使用shell_cmd代替cmd ）：

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

這應該比直接調用/bin/sh -c <stuff>更好，並且我認為您不再需要將cmd數組中的條目壓縮為單個字符串。

或者，您也可以嘗試在運行可執行文件之前使用env鍵（也在此處找到）指定LD_LIBRARY_PATH環境變量：

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