6.42.2. Installation of Man

This patch adds support for Internationalization:

patch -Np1 -i ../man-1.6f-i18n-1.patch

The following patch will add support for new compressors like XZ Utils:

patch -Np1 -i ../man-1.6f-new_compressors-1.patch

A few adjustments need to be made to the sources of Man.

First, a sed substitution is needed to modify configure's default search path for executables. It cycles through the values in PREPATH until it finds the program it is looking for. The -R switch is also added to the PAGER variable so that escape sequences are properly handled by Less:

cp configure{,.orig}
sed -e "/PREPATH=/s@=.*@=\"$(eval echo ${CLFS}/{,usr/}{sbin,bin})\"@g" \
    -e 's@-is@&R@g' configure.orig > configure

Another couple of sed substitutions comment out the “MANPATH /usr/man” and “MANPATH /usr/local/man” lines in the man.conf file to prevent redundant results when using programs such as whatis:

cp src/man.conf.in{,.orig}
sed -e 's@MANPATH./usr/man@#&@g' \
    -e 's@MANPATH./usr/local/man@#&@g' \
    src/man.conf.in.orig > src/man.conf.in

Prepare Man for compilation:

./configure -confdir=/etc

Configure was modified to look in ${CLFS} for the paths of helper programs. Right now all of the programs have ${CLFS} as a prefix. Remove that prefix with the following command:

cp conf_script{,.orig}
sed "s@${CLFS}@@" conf_script.orig > conf_script

The makemsg program, in Man's source, is executed during the build. Compile it using the host's gcc:

gcc src/makemsg.c -o src/makemsg

Compile the package:

make

Install the package:

make DESTDIR=${CLFS} install

If the character set of the locale uses 8-bit characters, search for the line beginning with “NROFF” in /etc/man.conf, and verify that it matches the following:

NROFF /usr/bin/nroff -Tlatin1 -mandoc

Note that “latin1” should be used even if it is not the character set of the locale. The reason is that, according to the specification, groff has no means of typesetting characters outside International Organization for Standards (ISO) 8859-1 without some strange escape codes. When formatting man pages, groff thinks that they are in the ISO 8859-1 encoding and this -Tlatin1 switch tells groff to use the same encoding for output. Since groff does no recoding of input characters, the f ormatted result is really in the same encoding as input, and therefore it is usable as the input for a pager.

This does not solve the problem of a non-working man2dvi program for localized man pages in non-ISO 8859-1 locales. Also, it does not work with multibyte character sets. The first problem does not currently have a solution. The second issue is not of concern because the CLFS installation does not support multibyte character sets.
