I had noticed `pkg-config --list-all` is listing two udev packages, `udev` and `libudev`. `pkg-config --libs udev` prints nothing but `pkg- config --libs libudev` prints `-ludev`.
I had also noticed that the link command did not featured `-ludev`. I also had tried to set compile/link flags to `-ludev` using environment variables without success at the time, but now that I just retried I noticed that if I delete the build dir, the flags are used and the build pass. I assume `libudev.h` is found properly because the code compiles, the error is a link error. Now, why there are two udev packages listed by pkg-config and why the linker flag isn't passed to mesa is a mystery to me. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1990315 Title: cannot link against libudev Status in systemd package in Ubuntu: Incomplete Bug description: When building Mesa vulkan drivers I get a lot of those error messages and the build fails: ``` error: undefined symbol: udev_new error: undefined symbol: udev_monitor_get_fd error: undefined symbol: udev_monitor_new_from_netlink error: undefined symbol: udev_monitor_receive_device error: undefined symbol: udev_monitor_unref error: undefined symbol: udev_unref error: undefined symbol: udev_device_unref error: undefined symbol: udev_device_get_property_value error: undefined symbol: udev_monitor_filter_add_match_subsystem_devtype error: undefined symbol: udev_monitor_enable_receiving ``` It worked on Ubuntu 21.10.
