Delphi 包构建/安装调试

Question

我使用的是 Delphi 2007 Pro。我有一个运行时包，其中包括我正在开发的许多基于 TFrame 的复合组件。还有一个相关的设计包将这些组件安装到工具选项板中。由于各种原因，这些 TFrame 后代使用许多第三方组件，并且也作为类层次结构相互继承。到目前为止(在一些很好的建议的帮助下)，这种方法对于我想要实现的目标非常有效。

最近我在编译/构建运行时包时遇到了一个问题。最初，它与以 nxEventLog.pas 为中心的一些冲突有关，不幸的是我未能记录其详细信息，但基本上是“此方法的定义与之前的定义不一致”的内容，就像当您的实现声明与您的类声明不一致时所得到的结果一样。该文件是 NexusDB 文件(应用程序使用 NexusDB 嵌入式服务器)。

我尝试了各种方法，但从未成功地消除冲突。我最接近的是在编译时，让 IDE 请求将完全不相关的单元的 TRUCKLOAD 添加到 contains/uses 子句中。稍后会详细介绍这一点，但如果我继续这样做，它仍然行不通。 nxEventLog 文件与原始状态相比没有发生变化。

无法找出为什么会出现此错误 - 它显示在 Nexus 文件中，而不是我的实际包或单元中，并且我没有更改 Nexus 代码中的任何内容 - 我最终继续并完全卸载了 Nexus ，并手动搜索以尝试确保我已删除所有相关的 dcu 和 bpl 文件，然后重新安装。 (我运行的是 Nexus 2.07)

启动 IDE 后，出现以下错误:

bds.exe - Entry Point Not Found
---------------------------
The procedure entry point
@Nxsddatadictionary@TnxBaseTableDescriptor@LoadFromReader$qqrp15Classes@TReader could not be located in the dynamic link library NexusDB207sd110.bpl.
---------------------------
OK

后跟:

Can't load package ....NexusDB207dv110.bpl
Can't load package ....cmTPPanels_D2007_DesignReg.bpl
The specified procedure oculd not be found.
Do you want to attempt to load this package the next time a package is loaded?

一旦我通过组件 -> 安装包 -> 删除卸载了 cmTPPanels 运行时/设计包(我的组件集)，我的其他“普通 Nexus DB”应用程序似乎工作正常，包括那些包含 Nexus 的 nxEventLog 组件的应用程序。这似乎表明问题肯定出在我的安装包中的某个地方。

因此，在确认我的 Nexus 安装似乎不是实际问题后，我打开了包含这两个包的项目组。构建(或编译)运行时包，Delphi IDE 给我提供了与上面提到的相同的对话框:

奇怪的是，除了厨房水槽之外几乎所有东西都包括在内之外，提到的许多软件包甚至与我试图安装的这个软件包中包含的组件无关； DataSnap、Indy、IBExpress、RemObjects Data Abstract 等——我的组件中甚至没有引用这些。

如果我对所有这些添加的单元/包单击“确定”，则会发生更多困惑，并且无法编译。

NexusDB 文件夹以及我正在开发的这些组件所在的文件夹都位于我的库路径上，我的自定义组件列在最后。

我正在虚拟机上工作，并且可以根据需要进行快照，但无论如何我似乎都无法解决这个问题，而且很明显我对编译器的工作原理没有足够深入的了解知道在哪里寻找问题的诊断。任何人都可以提到的任何可能对我有所帮助的内容，将不胜感激。

Answer 1

通常，这些错误来自于路径上具有不兼容的相同 BPL 和/或 DCP 文件，或者更常见的是，具有多个版本。对系统中的所有 BPL 和 DCP 进行全面搜索，并确保每个 BPL 和 DCP 都只有一份副本。

追踪这些类型的错误可能是一件非常痛苦的事情。 :-/
