Package: libdevmapper-dev Version: 2.02.127-1 Severity: serious Dear Maintainer,
There are a couple of problems with the dependencies of libdevmapper-dev and/or the included devmapper.pc file. The /usr/lib/x86_64-linux-gnu/pkgconfig/devmapper.pc file states: Requires.private: libudev librt This means packages build against/using devmapper.pc will fail to configure. As an example it might look like this: configure:6523: checking for LVM_DEPS configure:6533: $PKG_CONFIG --exists --print-errors "polkit-gobject-1 >= 0.92 $POLKIT_REQUIREMENT lvm2app gudev-1.0 >= 164" 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 configure:6539: $? = 1 configure:6559: $PKG_CONFIG --exists --print-errors "polkit-gobject-1 >= 0.92 $POLKIT_REQUIREMENT lvm2app gudev-1.0 >= 164" 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 configure:6565: $? = 1 configure:6582: result: no The solution is to include a dependency on the package shipping the relevant .pc files, eg libudev.pc and librt.pc. The first one is easily fixed since libudev.pc file is included in libudev-dev. Just make libdevmapper-dev depend on libudev-dev. The librt.pc file does not seem to be shipped by any package in Debian. Likely the generation of devmapper.pc was not right, since the the Requires.prive line seems to be generated according to: http://sources.debian.net/src/lvm2/2.02.127-1/libdm/libdevmapper.pc.in/#L11 My suspicion is that @RT_PC@ should have ended up empty on Debian. The configure.in script seems to be flawed by assuming that if there's a librt.so, then there's also a librt.pc.... cf. AC_CHECK_LIB vs PKG_CHECK_MODULES. As an alternative you might want to convince the glibc maintainers to ship the/a librt.pc file.
