Clang-Tidy fails when I include PQXX library #139286

cla-db · 2025-05-09T16:29:52Z

My project uses clang-tidy with no issues. Recently I added to PQXX library (https://pqxx.org/libpqxx/) to connect to a Postgres database and since then clang-tidy fails.

I can confirm that simply including the library causes the failure, no matter what the code does with that library (even nothing).

Steps to reproduce:

Instal the PQXX library on the system
Add #include <pqxx/pqxx> to a .cpp file
Run clang-tidy on that file

This is fixed in clang-tidy-20 (but not in 19th)

Test file:

#include <pqxx/pqxx>

int main() {}

Command run:
clang-tidy-20 --checks=* --extra-arg='-frtti' libpg.cpp

Clang-tidy version:

Ubuntu LLVM version 20.1.5
  Optimized build.

vbvictor · 2025-05-10T13:47:41Z

Could you please confirm there is no issue with clang-tidy-20?

cla-db · 2025-05-12T07:47:30Z

Confirmed: the issue is resolved with clang-tidy-20.
Thank you for the speedy response!
