Chapter 8. Installing Basic System Software

8.77. Man-DB-2.13.0

The Man-DB package contains programs for finding and viewing man pages.

Approximate build time: 0.3 SBU
Required disk space: 43 MB

8.77.1. Installation of Man-DB

Prepare Man-DB for compilation: 

./configure --prefix=/usr                         \
            --docdir=/usr/share/doc/man-db-2.13.0 \
            --sysconfdir=/etc                     \
            --disable-setuid                      \
            --enable-cache-owner=bin              \
            --with-browser=/usr/bin/lynx          \
            --with-vgrind=/usr/bin/vgrind         \
            --with-grap=/usr/bin/grap

The meaning of the configure options:

--disable-setuid

This disables making the man program setuid to user man.

--enable-cache-owner=bin

This changes ownership of the system-wide cache files to user bin.

--with-...

These three parameters are used to set some default programs. lynx is a text-based web browser (see BLFS for installation instructions), vgrind converts program sources to Groff input, and grap is useful for typesetting graphs in Groff documents. The vgrind and grap programs are not normally needed for viewing manual pages. They are not part of LFS or BLFS, but you should be able to install them yourself after finishing LFS if you wish to do so.

Compile the package: 

make

To test the results, issue: 

make check

Install the package: 

make install

8.77.2. Non-English Manual Pages in LFS

The following table shows the character set that Man-DB assumes manual pages installed under /usr/share/man/<ll> will be encoded with. In addition to this, Man-DB correctly determines if manual pages installed in that directory are UTF-8 encoded.
