Title: LLVM Compiler Configuration
Post by: Frank_CB on March 13, 2022, 10:00:04 pm

Has anyone been able to successfully configure a compiler in Codeblocks to use LLVM rather than c/c++ executables. I'm currently using NB 12748 and LLVM Release 13.0.1 on a Windows 10 (64-bit) system.  LLVM (Compiler Infrastructure Project) supposedly has made drop-in replacements for cl.exe, rc.exe and link.exe.

Any suggestions would be greatly appreciated!

I used the Code::Blocks "LLVM Clang Compiler" toolchain settings with C::B version 20.03 SVN 11983.

Using MSys2 "mingw-w64-clang-x86_64-clang 13.0.1-3"

Code

clang version 13.0.1
Target: x86_64-w64-windows-gnu
Thread model: posix
InstalledDir: C:/msys64/clang64/bin

Code

-------------- Build: Debug in testclangc++ (compiler: LLVM Clang Compiler)---------------

clang++.exe -Weverything -fexceptions -g  -c H:\test_cbp\testclangc++\main.cpp -o obj\Debug\main.o
clang++.exe  -o bin\Debug\testclangc++.exe obj\Debug\main.o   
Output file is bin\Debug\testclangc++.exe with size 156.50 KB
Process terminated with status 0 (0 minute(s), 1 second(s))
0 error(s), 0 warning(s) (0 minute(s), 1 second(s))

It built and ran a simple hello world program okay; not done anything other than that.

Thanks @stahta01. This provides a place to start.  It's given me a couple of ideas.

Regards!
