GNU dbm README See the end of file for copying conditions. * Introduction This file contains brief information about configuring, testing and using GNU dbm. It is *not* intended as a replacement for the documentation, instead it is provided as a brief reference only. The complete documentation is available in doc/ subdirectory. To read the manpage without installing the package use `man doc/gdbm.3'. To read texinfo documentation without installing the package, run `info -f doc/gdbm.info'. After the package is installed the documentation can be accessed by running `man gdbm' and `info gdbm'. * Overview GNU dbm is a set of database routines that use extendible hashing and works similar to the standard UNIX dbm routines. The library provides also an optional compatibility layer for UNIX-like dbm and ndbm calls. * Configuration a) configure [PARAMETERS] b) make For a list of generic PARAMETERS, see the file INCLUDE. The gdbm-specific parameters are: ** --enable-memory-mapped-io Enable the use of mmap(2) for I/O optimizations. This is the default, if mmap is available. To disable mmap, use --disable-memory-mapped-io. ** --enable-libgdbm-compat Build and install libgdbm_compat, a compatibility layer which provides UNIX-like dbm and ndbm interfaces. It includes two header files: dbm.h and ndbm.h, which are installed into $includedir. If you wish to install them elsewhere, define the variable COMPATINCLUDEDIR, e.g. ./configure --enable-libgdbm-compat COMPATINCLUDEDIR=/usr/include/gdbm ** --without-readline Don't compile GNU Readline support. By default, configure enables line-editing support if GNU Readline is available on the system. ** --enable-gdbmtool-debug This option instruments gdbmtool for additional debugging. Configured with this option, gdbmtool accepts two additional arguments: --lex-trace, which enables tracing the operation of the lexical analyzer, and --gram-trace, which enables parser tracing output. Note, that bison and flex must be installed for this option to take effect, * Installation make install This package also contains the 'magic' file for the file(1) utility - src/gdbm.magic. It is not installed by default, as its installation location differs considerably between various distributions. The most straightforward (but not the best one) approach is appending its content to /etc/magic: cat src/gdbm.magic >> /etc/magic See the documentation in your distribution for detailed instructions on how to install this file. * Bug reporting Please report bugs to <bug-gdbm@gnu.org> * Documentation, updates etc. For the latest updates, visit <http://www.gnu.org/software/gdbm>, In particular, a copy of GDBM documentation in various formats is available online at <http://www.gnu.org/software/gdbm/manual>. Latest versions of GDBM can be downloaded from anonymous ftp://ftp.gnu.org/gnu/gdbm.
