Basic Installation
==================
These are generic installation instructions.
The `configure' shell script is used to create the whole CMake
infrastructure in the 'build' subdirectory created where the soure files
were unpacked.
The default build type is `Release' but you can build a debug one by
running `configure' with the shel variable `WITH_DEBUG' set to "yes"; the
default value of this variable is "no"
Use WITH_DEBUG="yes" ./configure to configure a `Debug' build in which
case the created binary will not be striped and no optimization occurs
during compilation process
The simplest way to compile this package is:
1. `cd' to the directory containing the package's source code and type
`./configure' to configure the package for your system. If you're
using `csh' on an old version of System V, you might need to type
`sh ./configure' instead to prevent `csh' from trying to execute
`configure' itself.
Running `configure' takes a while. While running, it prints some
messages telling which features it is checking for.
2. Type `make' to compile the package.
3. Type `make [DESTDIR=PATH] install' to install the programs and any
data files and documentation.
4. You can remove the program binaries and object files from the
source code directory by typing `make clean'.
Compilers and Options
=====================
Some systems require unusual options for compilation or linking that
the `configure' script does not know about. You can give `configure'
initial values for variables by setting them in the environment. Using
a Bourne-compatible shell, you can do that on the command line like
this:
CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
Or on systems that have the `env' program, you can do it like this:
env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
Compiling For Multiple Architectures
====================================
You can compile the package for more than one kind of computer at the
same time, by placing the object files for each architecture in their
own directory. To do this, you must use a version of `make' that
supports the `VPATH' variable, 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 the directory that `configure' is in and in `..'.
If you have to use a `make' that does not supports the `VPATH'
variable, you have to compile the package for one architecture at a time
in the source code directory. After you have installed the package for
one architecture, use `make distclean' before reconfiguring for another
architecture.
Installation Names
==================
By default, `make install' will install the package's files under
`/usr' which is the default value of `prefix'. You can specify an
installation prefix other than `/usr' by running `configure' with the
variable `prefix' set to the desired path.
Run: "prefix=PREFIX ./configure"
Running `make DESTDIR=PATH install' will install the files under
PATH/PREFIX (default value is: `/usr' )
