Build dependencies:
- A Linux, BSD, or POSIX-like shell and environment. Mac OSX should
work, and so should Cygwin or MSYS on Windows.
- A C compiler. The default is your system's "cc"; override the Makefile's
CC variable if you need to (see "Variables" section below).
- Perl 5.x. Pretty much any version will do.
- rst2man. Only needed for regenerating the man pages.
- make. This can be GNU, BSD, makepp, or probably any other standard-ish
make (anyone still using Solaris?).
The build deps aren't required at runtime. The executables only use
the standard C library (e.g. libc.so.6 on Linux), and can be statically
linked if you want (try 'LDFLAGS="-static"').
Building:
If you're experienced at building software from source, src/Makefile
should be self-explanatory.
If you're not experienced, you can start by extracting the source:
tar xvf unalf-<ver>.tar.gz # replace <ver> with the actual version!
Next, compile the software:
make
If you're on Slackware:
sudo make install # or, as root, just 'make install'
This will install the binaries, man pages, and docs in locations
appropriate for Slackware Linux (since that's what the author uses).
If you're on a Debian or Ubuntu derivative, use:
sudo make install MANDIR=/usr/share/man DOCDIR=/usr/share/doc/unalf
If you're on some other OS (Red Hat, *BSD, OSX, etc), ask someone
who actually uses that OS if you're not sure where things should be
installed to.
If you prefer /usr/local:
sudo make install PREFIX=/usr/local MANDIR=/usr/local/share/man DOCDIR=/usr/local/share/doc/unalf
Variables:
You can set variables on the make command line. Example:
make CC=clang COPT=-Os # use a different compiler, optimize for size
See the top of src/Makefile for details on what variables exist and what
they're used for (not going to duplicate the list here).
