= Building on Unix with Autotools = 

The following instructions are dedicated to users of Unix-like systems (Linux, Mac OS X, Solaris, *BSD, etc.)

== Requirements ==

 * Decent C++ compiler and C++ Standard Library, [http://gcc.gnu.org/ GNU GCC] 4.x or later recommended.[[BR]]For specific distributions, use the commands:
   * ''CentOS'' (as root): {{{yum install gcc gcc-c++}}}
   * ''Ubuntu'': {{{sudo apt-get install build-essential}}}
 * Download the latest source code release or checkout from SVN trunk.

== Configure ==

(If you didn't download from SVN, skip this step.) If you are building GEOS downloaded from SVN, you need to have [http://en.wikipedia.org/wiki/GNU_build_system Autotools] available in your system. You will generate the ''./configure'' script with:

{{{
$ ./autogen.sh
}}}

Now, run configuration script:

{{{
$ ./configure
}}}

For more details about configuration options run:
{{{
$ ./configure --help
}}}

== Build ==

{{{
$ make
}}}

== Test ==

{{{
$ make check
}}}

== Install ==

You may need to use '''sudo''' to get this to run.

{{{
$ make install
}}}

== Build Hints ==

Feel free to update this article with build hints related to Autotools-based configuration that may be useful for users of Unix-like systems.

=== Solaris ===

 * From #331 - Build fails on linking on Solaris

{{{
$ LIBS="-lm" ./configure ...
}}}
