为什么链接器找不到tcl / tk？

Question

我正在用d语言测试官方tcl / tk样本，但在链接步骤失败了。我在Linux Mint 19 Cinamon 64bit上，我至少安装了

• libtcl8.6
• libtk8.6

另外，我使用的是DUB版本1.14.0，建于2019年4月5日

我去了tk绑定页面并按照Linux的步骤进行操作：binding page：

1. 安装tcl / tk 8.6库
2. 代码示例的用法

...

class Application : TkdApplication                       // Extend TkdApplication.
{
    private void exitCommand(CommandArgs args)           // Create a callback.
    {
        this.exit();                                     // Exit the application.
    }

    override protected void initInterface()              // Initialise user interface.
    {
        auto frame = new Frame(2, ReliefStyle.groove)    // Create a frame.
            .pack(10);                                   // Place the frame.

        auto label = new Label(frame, "Hello World!")    // Create a label.
            .pack(10);                                   // Place the label.

        auto exitButton = new Button(frame, "Exit")      // Create a button.
            .setCommand(&this.exitCommand)               // Use the callback.
            .pack(10);                                   // Place the button.
    }
}

...

编译输出

$ dub

'ne peut trouver'的意思是“找不到”。

这是我的dub.json

        "xcopy $TCLTK_PACKAGE_DIR\\dist\\library build\\library /i /e /y"
    ]
}

同时，我刚刚发现libtcl8.6.a和libtk8.6.a都在/ usr / lib / x86_64-linux-gnu下。我试着设定

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/x86_64-linux-gnu

但它既不起作用也不起作用。

Answer 1

最后我管理了！

我创建了几个软链接：

sudo ln -s /usr/lib/x86_64-linux-gnu/libtcl8.6.a /usr/lib/libtcl.a
sudo ln -s /usr/lib/x86_64-linux-gnu/libtk8.6.a /usr/lib/libtk.a
sudo ln -s /usr/lib/x86_64-linux-gnu/libtcl8.6.so /usr/lib/libtcl.so
sudo ln -s /usr/lib/x86_64-linux-gnu/libtk8.6.so /usr/lib/libtk.so

因此运行dub成功编译。
