Requirements
------------
You will need a C99 compiler. (gcc 3.3.6 or newer is recommended).
I use gcc 6.1.0 and 3.3.6, but the code should compile with any standards
compliant compiler.
Gcc is available at http://gcc.gnu.org.
The operating system must allow signal handlers read access to objects with
static storage duration so that the cleanup handler for Control-C can delete
the partial output file. (This requirement is for minilzip only).
Procedure
---------
1. Unpack the archive if you have not done so already:
tar -xf lzlib[version].tar.lz
or
lzip -cd lzlib[version].tar.lz | tar -xf -
This creates the directory ./lzlib[version] containing the source code
extracted from the archive.
2. Change to lzlib directory and run configure.
(Try 'configure --help' for usage instructions).
cd lzlib[version]
./configure
If you choose a C standard, enable the POSIX features explicitly:
./configure CFLAGS+='--std=c99 -D_XOPEN_SOURCE=500'
If you are compiling on MinGW, use:
./configure CFLAGS+='-D __USE_MINGW_ANSI_STDIO'
3. Run make
make
to build the library, or
make bin
to build also minilzip.
4. Optionally, type 'make check' to run the tests that come with lzlib.
5. Type 'make install' to install the library and any data files and
documentation. You need root privileges to install into a prefix owned
by root. (You may need to run ldconfig also).
Or type 'make install-compress', which additionally compresses the
info manual after installation.
(Installing compressed docs may become the default in the future).
You can install only the library or the info manual by typing
'make install-lib' or 'make install-info' respectively.
'make install-bin' installs the program minilzip and its man page. It
installs a shared minilzip if the shared library has been configured.
Else it installs a static minilzip.
'make install-bin-compress' additionally compresses the man page after
installation.
'make install-as-lzip' runs 'make install-bin' and then links minilzip to
the name 'lzip'.
Another way
-----------
You can also compile lzlib into a separate directory.
To do this, you must use a version of 'make' that supports the variable
'VPATH', such as GNU 'make'. 'cd' to the directory where you want the
object files and executables to go and run the 'configure' script.
'configure' automatically checks for the source code in '.', in '..', and
in the directory that 'configure' is in.
'configure' recognizes the option '--srcdir=DIR' to control where to look
for the source code. Usually 'configure' can determine that directory
automatically.
After running 'configure', you can run 'make' and 'make install' as
explained above.
