【问题描述】：

我想安装嵌入在 C++ Builder v.6 上的 chromium。很久以前我已经安装过一次，我使用 TChromium 开发了一些应用程序。但是在我重新安装操作系统后，我试图再次安装这个组件。当我编译 delphi 帕斯卡单元时，我得到了链接器错误：

我只是点击了组件 -> 安装组件 -> 选择了 cefvcl.pas，然后当我点击编译时，我得到了上面的结果。

如何在 BCB6 上安装 chromium，或者如何解决这个问题？

更新：

另外，当我尝试编译时，我收到未声明的 indentifer 错误，代码在哪里：

TThread.Synchronize(nil, sync.Execute);

我只是通过删除 syncronize 绕过它，所以之后的行看起来像：

sync.Execute;

更新2

如果我正在尝试其他方式来安装组件，我正在创建新包并保存它，然后向其中添加 4 个文件：

cefreg.pas
ceflib.pas
cefvcl.pas
cefgui.pas

然后我替换 TThread.Synchronize(nil, sync.Execute);与同步。执行；绕过错误，但在那之后我仍然有一个问题：

[Linker Fatal Error] Fatal: Unable to open file 'APPEVNTS.OBJ'

    【解决方案1】：

    您正在将所选组件安装到 IDE 的默认自定义组件包中。该包显然引用了TOutline 组件，但该组件未在包中定义。通常，TOutline 在 vclsmp 包中，因此请将 vclsmp 添加到组件包的 requires 列表中。

    最好使用不同且更典型的技术来安装 Chromium 控件。与其在默认的自定义组件包中只添加一个单元，不如安装 Chromium 组件自带的现成包： 打开与你的 Delphi 版本对应的 .dpk 文件，编译并安装它。如果您的产品版本没有包文件，则只需将四个源文件添加到新包中；使用现有的 .dpk em>文件作为示例。

    您的一些麻烦可能是因为该库是针对比 2002 年的 C++ Builder 6 更高的产品版本而编写的。例如，似乎期望 TThread 有一个 Synchronize 的两个参数版本，并且在那里是一个AppEvnts 单元。简单地删除你没有的东西而不理解它们并不是解决这个问题的方法，尤其是当涉及到线程时。

    所有源文件引用cef.inc，根据编译器版本设置条件定义。如果它无法识别您的编译器版本，则必须对其进行编辑，以便它设置各种版本符号和功能符号以准确描述您的编译环境。

    • 谢谢智能提示，我很欣赏它。我已经更新了我的帖子。我的第二次尝试是创建新包并将文件添加到它。您能否更新您的答案并告诉我在哪里位于VCLSMP包。您还说要打开 .dpk 文件编译并安装它，但我使用的是 C++ Builder 6 而不是 Delphi。谢谢
