Package: libdevmapper-dev Version: 2:1.02.104-1 Severity: important Dear Maintainer,
Use of pkg-config with libdevmapper isn't working due to a Requires.private dependence on librt. There's no librt.pc file, so this breaks: [skynet](0) $ pkg-config --print-requires-private devmapper Package librt was not found in the pkg-config search path. Perhaps you should add the directory containing `librt.pc' to the PKG_CONFIG_PATH environment variable Package 'librt', required by 'devmapper', not found [skynet](1) $ I think what you want here is a Libs.private line with -lrt, and to remove librt from the Requires.private. librt is not a "package" in the pkg-config world, and can't be used this way. -- System Information: Debian Release: stretch/sid APT prefers unstable APT policy: (500, 'unstable'), (500, 'stable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.2.0-1-amd64 (SMP w/8 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages libdevmapper-dev depends on: ii libdevmapper-event1.02.1 2:1.02.104-1 ii libdevmapper1.02.1 2:1.02.104-1 ii libselinux1-dev 2.3-2+b1 libdevmapper-dev recommends no packages. libdevmapper-dev suggests no packages. -- no debconf information
