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，我收到链接器错误：

我只是单击了组件-> 安装组件-> 选择了 cefvcl.pas，然后当我单击编译时，我得到了以上结果。

如何在 BCB6 上安装铬，或者如何解决这个问题？

更新：

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

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

如果我尝试以其他方式安装组件，我将创建新包并保存它，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，但之后我仍然有一个问题：

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

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

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 组件附带的现成包：打开与您的 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 更高的产品版本编写的。例如，它似乎期望有一个AppEvnts单元TThread的两个参数版本。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。Synchronize

所有源文件都引用cef.inc，它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。
