Thanks, I some how make it work. Although I did not use your project directly, but I got a lot of inspiration from it. Basically, what I was trying to do was to compiling Unreal Code using a Linux version clang in WSL, which is difficult to achieve since it at least require I set up the cross-compiling for the project.
After I switch to the Windows native Emacs and Clangd, everything works fine. During this process, I also have learned more about how these macro works actually with the help of UHT.
However, there is still another problem bothering me. The thing is when I edit some content of a header file, to be specific, when I make some edit which changes the line number of the GENERATED_BODY macro, the header file is broken. This is due to the #define in the .generated.h file can’t match the GENERATED_BODY after the line number has changed. Before the next time I run the UHT, those error messages clangd send to me persist.
The only way I know how to run the UHT is through the IDE’s building process, which it automatically run UHT and generate the headers. If I could find out how to run UHT manually, then I can update my generated header files without building the project after I made some simple changes to my header file. Sometimes, those changes are too naive to issue another build, e.g., including another header file or forward declaring a class name, etc…
I have tried Jet Brain’s Rider for Unreal and it works that way, I mean, automatically running UHT in background to update generated header file to make everything in the same page.
Unreal document talks really little about how to execute UHT manually, if you know how to do that, please tell me, that would be a really great help.
P.S. Clangd is somehow slow to reflect changes in header files, even UHT is not involved.
