[BUG] Compilation failure with Clang on Windows
I get a compiler error when I compile the sources.
- compiler: clang version 18.1.6
- standard library: MSVC version 14.35.32215
- OS: Windows 11 version 23H2
This is the error I get:

I also get a error when trying to compile with MSVC.

Interesting, I was seeing a similar error to your clang++ compilation when invoking cl - mentioned here: https://github.com/hsutter/cppfront/discussions/1293
Its weird that your cl is having a hard time seeing the includes though. I thought it would pick those up automatically. Are you running cl from the Developer Powershell for VS 2022 shell?
I was running the command from Powershell but using Developer Command Prompt it works with cl. It seems that the error was on my side, sorry :sweat_smile: I guess I'm missing some paths in my environment variables, even though I do have the path to MSVC includes. However, this doesn't solve my problem with the Clang compiler.
Yea, so I just tested this with a fresh install of MingW and also Clang the same as you; nothing is compiling for me on any of them either.
On clang, I'm getting exactly the same errors you're getting. Using MingW g++, I'm getting the issue mentioned in the guide
Note: On Windows (including MinGW), if you get a "too many sections" message, specify the switch /bigobj (MSVC) or /Wa,-mbig-obj (GCC).
But using the /Wa,-mbig-obj isn't fixing it. When I ran g++ inside of a linux vm, it compiled perfectly in just a couple of seconds - so it seems like building in windows is just problematic at the moment
Hey so I'm not sure why clang isn't compiling properly, but your msvc version looks old. I was running into this same issue with cl version 14, update it to 19 and it should start working for msvc compiler
For now, I'm compiling completely with MSVC and it's working properly, I haven't retried compiling with Clang.
Chiming in to report that this is still an issue on:
╰─❯ clang++ --version
