Énoncé§
Solve this question on: app-srv1
Install the text based terminal browser links2 from source on server app-srv1. The source is provided at /tools/links-2.14.tar.bz2 on that server.
Configure the installation process so that:
- The target location of the installed binary will be
/usr/bin/links - Support for ipv6 will be disabled
Solution§
Let’s first check out the provided archive and extract it’s content:
ssh app-srv1
root@app-srv1:~$ cd /tools
root@app-srv1:/tools$ ls
links-2.14.tar.bz2We’ll go ahead and extract the archive:
root@app-srv1:/tools$ tar xjf links-2.14.tar.bz2
root@app-srv1:/tools$ cd links-2.14
root@app-srv1:/tools/links-2.14$ ls -lh

...The usual process of installing from source is:
./configure (args...)makemake installHere the question requires specific configuration parameters. We can list all possible options:
root@app-srv1:/tools/links-2.14$ ./configure -help
Usage: configure [options] [host]
Options: [defaults in brackets after descriptions]
Configuration:
--cache-file=FILE cache test results in FILE
--help print this message
--no-create do not create output files
--quiet, --silent do not print checking... messages
--version print the version of autoconf that created configureDirectory and file names:
—prefix=PREFIX install architecture-independent files in PREFIX # !! USEFUL
[/usr/local]
—exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
[same as prefix]
—bindir=DIR user executables in DIR [EPREFIX/bin]
—sbindir=DIR system admin executables in DIR [EPREFIX/sbin]
—libexecdir=DIR program executables in DIR [EPREFIX/libexec]
—datadir=DIR read-only architecture-independent data in DIR
[PREFIX/share]
—sysconfdir=DIR read-only single-machine data in DIR [PREFIX/etc]
—sharedstatedir=DIR modifiable architecture-independent data in DIR
[PREFIX/com]
…
—enable-graphics use graphics
—disable-utf8 disable UTF-8 terminal (saves memory)
—without-getaddrinfo compile without getaddrinfo function
—without-ipv6 compile without ipv6 # !! USEFUL
—without-libevent compile without libevent
—without-gpm compile without gpm mouse
—with-ssl(=directory) enable SSL support
—with-ssl=nss enable SSL support through NSS OpenSSL emulation
—disable-ssl-pkgconfig don’t use pkgconfig when searching for openssl
…
It’s also possible to open the ./configure file in a text editor to investigate possible options if the help output won’t suffice.
We now use the following configuration:
root@app-srv1:/tools/links-2.14$ ./configure --prefix /usr --without-ipv6
creating cache ./config.cache
checking for a BSD compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
checking whether make sets ${MAKE}... yes
checking for working aclocal-1.4... missing
checking for working autoconf... missing
...
creating ./config.status
creating Makefile
creating config.h
---------------------------------------------------------
Configuration results:
Event handler: NO
IPv6: NO
Supported compression: NO
SSL support: NO
UTF-8 terminal: YES
GPM support: NO
Graphics enabled: NO
---------------------------------------------------------After the configuration we continue with make:
