Setup:
Compiled with a recent version of Clang and LLVM. Ubuntu instructions for Clang/LLVM 18:
|
# Note: It is strongly recommended to uninstall all old Clang & LLVM packages (ref dpkg --list | grep -iE 'clang|llvm' and use apt purge and dpkg --purge to remove the packages), before installing Clang/LLVM 18
|
sudo apt install clang llvm-18 llvm-18-linker-tools llvm-18-runtime llvm-18-tools llvm-18-dev libstdc++-14-dev llvm-dev lld-18
|
Compiled with: "-DCMAKE_C_COMPILER=/usr/bin/clang -DCMAKE_CXX_COMPILER=/usr/bin/clang++ -DCMAKE_C{,XX}_FLAGS='-march=native -mtune=native'" and:
|
-DWITH_ASAN=ON -DWITH_ASAN_SCOPE=ON -DWITH_UBSAN=ON -DWSREP_LIB_WITH_ASAN=ON
