How can I build the project?

[Rohupt]

What should I do to link the Rust side to the C++ side of the project? Or more generally, what steps should I take to build a working product from the repository?

To be exact, I got linker errors during building:

This is most probably because of 32bit vs 64bit... Currently the project is configured to only support 64bit, so you need to choose x64/Debug.

A few more things:

• Update the setup of the IME #1 (comment)
• Update the setup of the IME #1 (comment)

[Rohupt]

Now I want to build this on Win32 configs. I will change the configurations myself, but could you give an outline of what should be done? I'm aware of the pre-build script, linkers and some of the tweaks, but in the end there are still errors.

[saschanaz]

The prebuild script also need to tell Rust to compile for 32bit, as it currently just do its default.

[Rohupt]

Let's say I want to build two versions of the dll (Win32 and x64) and register both of them together (because for some reasons the 32-bit dll won't work with x64 apps and vice versa), do I need to tweak the registry GUIDs, and if yes, which ones should I change and how to generate an acceptable GUID to change them to?

[saschanaz]

In that case I guess there should be some conditional compilation: https://doc.rust-lang.org/reference/conditional-compilation.html

Generating GUID is easy, DuckDuckGo search page even automatically generates one for you: https://duckduckgo.com/?t=ffab&q=guid&ia=answer

In this case I believe (but not sure, as I haven't tried) that these two should change.

Turns out it's quite complicated. According to here the CLSID keys should be identical. We need to call ImmInstallIMEA function to generate the registry key to share data for both the DLLs etc etc. I'll find out all about this and share it here later.

[Rohupt]

So... I don't actually have to change anything related to the GUIDs. Just create 2 versions of the DLL and install them into System32 and SysWOW64 (together with the dictionaries of course) and it's done.
