pkg-config can not resolve dependencies #24610
Description
What version of protobuf and what language are you using?
33.0
Language: C++
What operating system (Linux, Windows, ...) and version?
Linux (Ubunut)
What runtime / compiler are you using (e.g., python version or gcc version)
clang 21
What did you do?
- build from source using CMake and install to any DIR
- set PKG_CONFIG_PATH to the DIR/lib/pkgconfig
- execute
pkg-config protobuf --cflagsorpkgconf protobuf --cflags - Additional step is to execute
pkgconf protobuf --digraph
What did you expect to see
The output should be there within seconds
The dependencies graphs should have a sane size
What did you see instead?
pkg-config/pkgconf got stuck for minutes (I've been waiting for around 15)
The graph is insanely large (>2 millions nodes)
I'm honestly not an expert with any of pkg-config or pkgconf, but to me it looks like some kind of cyclic dependencies somewhere in CMake files
