The problem here is not so unusual: you say "link > against libblkdev" but forget to add possible dependencies. You needn't to specify all possible dependencies on gcc command line... see my previous e-mail. It works. The -lblkid is enough if your linker is able to evaluate dependencies and found all .so libs. Don't forget that libblkid includes all necessary information: $ objdump -x /lib/libblkid.so.1 | grep NEEDED NEEDED libuuid.so.1 NEEDED libdevmapper.so.1.02 NEEDED libc.so.6 > We could use pkg-config to get the dependend libs for libblkid, but I'm > not sure if all possible e2fsprogs versions are pkgconfigized. Right.
