When, for example, + /usr is not mounted, these + programs still need to be available. They belong in directories + like /lib and /sbin. If this option is not passed + to E2fsprogs' configure, the programs are installed into the + /usr directory. + + + + + --enable-elf-shlibs + + This creates the shared libraries which some programs + in this package use. + + + + + --disable-* + + This prevents E2fsprogs from building and installing the + libuuid and + libblkid libraries, the + uuidd daemon, and the + fsck wrapper, as Util-Linux installs more + recent versions. + + + + + + Compile the package: + +make + + To run the tests, issue: + +make check + + One of the E2fsprogs tests will attempt to allocate 256 MB of memory. + If you do not have significantly more RAM than this, be sure to enable + sufficient swap space for the test.
