<title>Building and Installing Fossil</title>




<h2>0.0 Using A Pre-compiled Binary</h2>

<p>You can skip all of the following by downloading
a <a href="http://www.fossil-scm.org/download.html">pre-compiled binary</a>
appropriate for your platform and putting that self-contained binary
someplace on your $PATH.
To uninstall, simply delete the binary.
To upgrade from an older release, just overwrite the older binary with
the newer one.</p>

<h2>0.1 Executive Summary</h2>

<p>Building and installing is very simple.  Three steps:</p>

<ol>
<li> Download and unpack a source tarball or ZIP.
<li> <b>./configure; make</b>
<li> Move or copy the resulting "fossil" executable to someplace
     on your $PATH.
</ol>

<p><hr>

<h2>1.0 Obtaining The Source Code</h2>

<p>Fossil is self-hosting, so you can obtain a ZIP archive containing
a snapshot of the latest version directly from fossil's own fossil
repository.  Follow these steps:</p>

<ol>
<li value="6">
<p>Create a directory to hold the source code.  Then unarchive the
ZIP or tarball you downloaded into that directory.  You should be
in the top-level folder of that directory</p></li>

<li><i>(Optional, unix only)</i>
Run <b>./configure</b> to construct a makefile.

<ol type="a">
<li><p>
If you do not have the OpenSSL library installed on your system, then
add <b>--with-openssl=none</b> to omit the https functionality.

<li><p>
To build a statically linked binary (suitable for use inside a chroot
jail) add the <b>--static</b> option.

<li><p>
Other configuration options can be seen by running
<b>./configure --help</b>
</ol>

<li><p>Run make to build the "fossil" or "fossil.exe" executable.  The
details depend on your platform and compiler.

<ol type="a">
<li><p><i>Unix</i> &rarr; the configure-generated Makefile should work on
all unix and unix-like systems.  Simply type "<b>make</b>".

<li><p><i>Unix without running "configure"</i> &rarr; if you prefer to avoid running configure, you
can also use: <b>make -f Makefile.classic</b>.  You may want to make minor
edits to Makefile.classic to configure the build for your system.

<li><p><i>Msys/MinGW</i> &rarr; Use the
mingw makefile: "<b>make -f win/Makefile.mingw</b>"

<li><p><i>VC++</i> &rarr; Use the msc makefile.  First
change to the "win/" subdirectory ("<b>cd win</b>") then run
"<b>nmake /f Makefile.msc</b>".

There are three preprocessors for the Fossil sources.  The mkindex
and translate preprocessors can be run in any order.  The makeheaders
preprocessor must be run after translate.

<h2>4.1 The mkindex preprocessor</h2>

The mkindex program scans the "src.c" source files looking for special
comments that identify routines that implement various Fossil commands,
web interface methods, and help text comments.  The mkindex program
generates some C code that Fossil uses in order to dispatch commands and
HTTP requests and to show on-line help.  Compile the mkindex program
from the mkindex.c source file.  Then run:

<blockquote><pre>
./mkindex src.c >page_index.h
