当内部单元使用DesignEditors DesignIntf​​时，如何为WIN64构建delphi项目？

Question

I am trying to migrate some code from Delphi 5 to Delphi XE7-WIN64. The scenario is DesignEditors is 32bit only since the IDE is 32 bit application. And the project I am migrating has units which have uses clause containing DesignEditors or DesignIntf or both.

Putting -LUDesignIDE in Build Configurations>Edit>Delphi Compiler>Compiling>Additional options to pass to compiler>-LUDesignIDE

Gives the following as first error on build

[dcc64 Fatal Error] E2202 Required package 'DesignIDE' not found

I am using Delphi XE7 trial version.

It sounds like you have a package which is both design-time and run-time combined into one. In most scenarios however, you must split your package into two different packages . One package is run-time (where you implement all of your actual library), and the other is design-time (which exposes your library to the IDE).

That being said, the design-time packages must work directly with the Delphi IDE. The Delphi IDE is 32bit, so the design-time package must also be 32bit. Whereas, your run-time package will support whatever platforms are needed. Your design-time package is only responsible for registering your components, property editors, etc. to the IDE.

Anything which has anything to do with the IDE (such as registering components, registering property editors, etc.) Must be in your design-time package which is only 32bit. Because of legal copyright issues, all design-time implementation must be in a design-time package, separate from your run-time package.

Start by creating a new design-time only package, same name but prefixed with DCL . Then, change your original package to run-time only. Create a new unit now in your new design-time only package. This unit will be dedicated to registering all IDE design-time interaction. Everything in your run-time package which relies on these design-time units must be converted over to this design-time package. These units which you cannot find are only compatible with the 32bit Delphi IDE.

The new design-time only package will then have to require your run-time package. You'll have to compile the run-time package first before you can compile the design-time package. Any time, you make changes to your library, you need to 1) re-compile the run-time package, 2) re-compile the design-time package, and 3) re-install the design-time package.

The ToolsAPI units can be included in Win32 designtime packages, and nowhere else. You are trying to include them in a Win64 executable project. That is not allowed.

The solution is that you remove all the ToolsAPI units from your project.
