在Delphi 2009和Delphi XE下安装相同组件无法正常工作 [英] Installing Same Components Under Delphi 2009 and Delphi XE not working

问题描述

我有一组在D2009中一直在使用的自定义组件。我已经安装了Delphi XE，并且希望在升级项目时能够在两个IDE中使用这些组件。但是当我在XE中安装它们时，它们在D2009中不再真正可用。项目仍然可以编译，但是组件不再显示在工具选项板中，它们也不会出现在表单设计器中。

无论我如何尝试要卸载/重新安装等，我无法在D2009中使用这些组件。我已经验证了两个IDE的库路径中都有该组件的目录。

我需要在这里做什么才能使两个IDE中的组件都能正常工作？

谢谢！

解决方案

不同版本的Delphi会生成不同的软件包集（ * .bpl文件）在不同的路径（包输出目录）中。设计包必须在运行时由IDE加载。现在，Windows搜索路径可能已发挥作用。当D2009想要加载软件包x.bpl时，它会解析为XE版本（不兼容），因为XE的软件包输出目录位于D2009之前的系统搜索路径中-如果您首先安装D2009，然后再安装XE，则会发生这种情况。 p>

解决方案是始终对软件包使用库后缀。我建议您遵循Delphi自己的约定，对D2009程序包使用120，对XE程序包使用150。对于D2009，您的x.bpl变为x120.bpl，对于XE，您的x.bpl变为x150.bpl。

I have a set of custom components that I've been using in D2009. I have installed Delphi XE, and I'd like to be able to use these components in both IDE's while I'm upgrading my projects. But when I install them in XE, they are no longer really usable in D2009. A project will still compile, but the components no longer show up in the Tool Palette, and they don't appear in the form designer either.

No matter how I try to uninstall/reinstall, etc., I can't get the components to work in D2009. I've verified that both IDE's have the component's directory in their library path.

What do I need to do here to get the components working in both IDE's?

Thanks!

解决方案

The different versions of Delphi produce different sets of packages (*.bpl files) in different paths ("package output directory"). The design packages have to be loaded at runtime by the IDE. Now the Windows search path probably comes into play; when D2009 wants to load package x.bpl it resolves to the (incompatible) XE version of it because XE's package output directory is in the system search path before D2009's - this happens if you installed D2009 first and XE later (recommended).

The solution is to always use Library Suffix for your packages. I suggest you go by Delphi's own convention and use 120 for D2009 packages and 150 for XE packages. Your x.bpl becomes x120.bpl for D2009 and x150.bpl for XE.
