Compiling CodeBlocks with clang

(1/2) > >>

everSome:
Is it reasonable to even be trying to do this? I'm using the 15.0.4 version of the clang and clang++ compiler drivers against the r13000 version of CodeBlocks. Any known gotchas? So far I've had to fix wxWidgets 3.2.1 since clang generates the following predefines:
#define __GNUC__ 4
#define __GNUC_MINOR__ 2

everSome:
Just to clarify, I'm experimenting with the MSYS2 binary package obtained via:
pacman -S --needed mingw-w64-ucrt-x86_64-clang
that ties into the gcc toolchain as I understand it without going the full llvm route, Could be wrong on this though.

everSome:
Any ideas on how to rectify this error:

Since it install an llvm package I have no idea why you think it does not go the full llvm route.

Me, I would try GCC under UCRT64 first because that at least will verify CB builds under UCRT64.

FYI, I'm using a version of CodeBlocks, r13019 to be exact, build with:

$ g++ --version
g++.exe (Rev6, Built by MSYS2 project) 12.2.0
Copyright (C) 2022 Free Software Foundation, Inc.
This is free software; see the source for copying conditions.  There is NO

to be exact, to utilize clang in compiling CodeBlocks. Here's the the pertinent output. I don't even get any warnings compiling it.
