6.13. Berkeley DB-4.4.20

The Berkeley DB package contains programs and utilities used by many other applications for database related functions.

Approximate build time: 1.2 SBU
Required disk space: 78 MB
Installation depends on: Bash, Binutils, Coreutils, Diffutils, GCC, Glibc, Make and Sed.
[Tip]

Other Installation Possibilities

There are instructions to build this package in the BLFS book if you need to build the RPC server or additional language bindings. The additional language bindings will require additional packages to be installed. See http://www.linuxfromscratch.org/blfs/view/svn/server/databases.html#db for suggested installation instructions.

Also, if you would prefer to skip Berkeley DB entirely and use GDBM instead, see the BLFS instructions located at http://www.linuxfromscratch.org/blfs/view/svn/general/gdbm.html

6.13.1. Installation of Berkeley DB

Prepare Berkeley DB for compilation: 

cd build_unix &&
../dist/configure --prefix=/usr --enable-compat185 --enable-cxx

The meaning of the configure options:

--enable-compat185

This option enables building Berkeley DB 1.85 compatibility API.

--enable-cxx

This option enables building C++ API libraries.

Compile the package: 

make

It is not possible to test the package meaningfully, because that would involve building TCL bindings. TCL bindings cannot be built properly now because TCL is linked against Glibc in /tools, not against Glibc in /usr.

Install the package: 

make docdir=/usr/share/doc/db-4.4.20 install

The meaning of the make parameter:

docdir=...

This variable specifies the correct place for the documentation.

Fix the ownerships of the installed files: 

chown -v root:root /usr/bin/db_* \
    /usr/lib/libdb* /usr/include/db* &&
chown -Rv root:root /usr/share/doc/db-4.4.20
