6.46.1. Installation of Man
Two adjustments need to be made to the sources of Man.
The first is a sed substitution to add the -R switch to the PAGER variable so that escape sequences are properly
handled by Less:
sed -i 's@-is@&R@g' configure
The second is also a sed substitution to comment out the
“MANPATH /usr/man” line in
the man.conf file to prevent
redundant results when using programs such as whatis:
sed -i 's@MANPATH./usr/man@#&@g' src/man.conf.in
Prepare Man for compilation:
./configure -confdir=/etc
The meaning of the configure options:
-
-confdir=/etc
-
This tells the man program to look for the
man.conf configuration file in
the /etc directory.
Compile the package:
make
Install the package:
make install
![[Note]](../images/note.png)
Note
To disable Select Graphic Rendition (SGR) escape sequences, edit
the man.conf file and add the
-c switch to the
NROFF variable.
If the character set uses 8-bit characters, search for the line
beginning with “NROFF” in
/etc/man.conf, and verify that it
looks as follows:
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 manual
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 formatted 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
manual 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 LFS
installation does not support multibyte character sets.

info pages can be found in the BLFS book at
