Bug ID: 506763
Summary: Undefined symbols builing clazy on MacOS with llvm20
Classification: Developer tools
Product: clazy
Version First unspecified
Reported In:
Platform: Compiled Sources
OS: macOS
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: unassigned-b...@kde.org
Reporter: skutni...@ornl.gov
CC: smart...@kde.org
Target Milestone: ---
SUMMARY
I am getting an undefined symbol error during the linking phase when building
clazy from source on MacOS Sequoia 15.5 (Intel processor), using llvm v20.1.7 +
clang v20.1.7. I am compiling from source off of the master branch at
https://invent.kde.org/sdk/clazy.
STEPS TO REPRODUCE
1. Configure clazy using CMake & NInja:
$ export CXX=clang++
$ export LLVM_ROOT=/usr/local/opt/llvm
$ cmake -G Ninja
2. Attempt to build:
$ cmake --build .
3. Target builds but fails on linker stage.
OBSERVED RESULT
Undefined symbols for architecture x86_64:
