udev is a hard dependency

[wdlkmpx]

In slackware 14.0 (old distro), udev is not detected.

I get this error

checking for UDEV... no
configure: error: Package requirements (udev) were not met:

No package 'udev' found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables UDEV_CFLAGS
and UDEV_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

udev is version 182... i can't disable udev. In NEWS i read:

• Include udev rule file for automatic managing of packet writing devices

I don't need that udev rule, but this requirement is preventing ./configure from succeeding.. that's wrong.

This is how it should be:

the build system detects whether udev is installed, if it's not installed it should silently continue disabling udev-specific code .. --enable-udev/--disable-udev should be used to enforce or ignore udev.

[pali]

pkg-config is searching for udev package, not libudev. To check if you have really installed udev development files, search for file udev.pc (not libudev.pc).

But you are right that build system should work even when udev is not installed. Whole udftools works correctly without udev installed or running in system.

Could you try following patch if it allows you to build udftools without udev?

Yes that fixes the issue. udftools compiles and works fine. Thanks
