If you are going to compile Wine, either to use the most recent
|
|
code possible or to improve it, then the first thing to do is to
|
|
obtain a copy of the source code. We'll cover how to retrieve and
|
|
compile the official source releases from the <link
|
|
linkend="getting-source-ftp">FTP archives</link>, and also how
|
|
to get the cutting edge up-to-the-minute fresh Wine source
|
|
code from <link linkend="getting-source-cvs">CVS (Concurrent
|
|
Versions System)</link>. Both processes of source code
|
|
installation are similar, and once you master one, you should
|
|
have no trouble dealing with the other one.
|
|
</para>
|
|
<para>
|
|
You may also need to know how to apply a source code patch to
|
|
your version of Wine. Perhaps you've uncovered
|
|
a bug in Wine, reported it to the <ulink
|
|
url="mailto:wine-devel@winehq.com">Wine mailing list</ulink>,
|
|
and received a patch from a developer to hopefully fix the
|
|
bug. We will show you how to
|
|
<link linkend="getting-upgrading">safely apply the
|
|
patch</link> and revert it if the patch doesn't work.

<para>

The safest way to grab the source is from one of the official
|
|
FTP archives. An up to date listing is in the <ulink
|
|
url="http://www.winehq.com/source/ANNOUNCE">ANNOUNCE</ulink>
|
|
file in the Wine distribution (which you would have if you
|
|
already downloaded it). Here is a list

The official releases are tagged by date with the format

Once you have downloaded this, you must first compile wine, and then
|
|
install it. This is not very hard to do. First switch to the
|
|
directory containing the file you just downloaded. Then extract the
|
|
source with (e.g.):
|
|
<screen>
|
|
<prompt># </><userinput>tar xzvf wine-<replaceable>20021031</>.tar.gz</>
|
|
</screen>
|
|
</para>
|
|
<para>
|
|
Then, switch to the directory that was created and compile it by typing (e.g.):
|
|
<screen>
|
|
<prompt># </><userinput>./tools/wineinstall</>
|
|
</screen>
|
|
</para>
|
|
<para>
|
|
NOTE: You must make sure that you are not the superuser (root) when doing this,
|
|
and that you have write permission to the directory that was created by the tar
|
|
command as well as all of its subdirectories and files..

<title>Getting Wine Source Code from CVS</title>
|
|
|
|
<para>
|
|
The official web page for Wine CVS is
|
|
<ulink url="http://www.winehq.com/development/">
|
|
http://www.winehq.com/development/</>.
|
|
</para>
|
|
<para>
|
|
First, you need to get a copy of the latest Wine sources
|
|
using CVS. You can tell it where to find the source tree by
|
|
setting the <envar>CVSROOT</envar> environment variable. You
|
|
also have to log in anonymously to the wine CVS server. In
|
|
<command>bash</>, it might look something like this:
|
|
<screen>
|
|
<prompt>$ </><userinput>export CVSROOT=:pserver:cvs@cvs.winehq.com:/home/wine</>
|
|
<prompt>$ </><userinput>cvs login</>
|
|
Password:
|
|
<prompt>$ </><userinput>cvs checkout wine</>
|
|
</screen>
|
|
</para>
|
|
<para>
|
|
That'll pull down the entire Wine source tree from
|
|
winehq.com and place it in the current directory (actually
|
|
in the 'wine' subdirectory). CVS has a million command line
|
|
parameters, so there are many ways to pull down files, from
|
|
anywhere in the revision history. Later, you can grab just
|
|
the updates:
|
|
<screen>
|
|
<prompt>$ </><userinput>cvs -PAd update</>
|
|
</screen>
|
|
</para>
|
|
<para>
|
|
<command>cvs update</> works from inside the source tree.
|
|
You don't need the <envar>CVSROOT</> environment variable
|
|
to run it either. You just have to be inside the source tree.
|
|
The <parameter>-P</>, <parameter>-A</> and <parameter>-d</>
|
|
options make sure your local Wine tree directory structure stays
|
|
in sync with the remote repository.
|
|
</para>
|
|
<para>
|
|
After you've made changes, you can create a patch with
|
|
<command>cvs diff -u</>, which sends output to stdout
|
|
(the <parameter>-u</> controls the format of the
|
|
patch). So, to create an <filename>my_patch.diff</>
|
|
file, you would do this:
|
|
<screen>
|
|
<prompt>$ </><userinput>cvs diff -u ><replaceable>my_patch.diff</></>
|
|
</screen>
|
|
</para>
|
|
<para>
|
|
You can call <command>cvs diff</command> from anywhere in the
|
|
tree (just like <command>cvs update</command>), and it will
|
|
always grab recursively from that point. You can also specify
|
|
single files or subdirectories:
|
|
<screen>
|
|
<prompt>$ </><userinput>cvs diff -u dlls/winaspi ><replaceable>my_aspi_patch.diff</></>
|
|
</screen>
|
|
</para>
|
|
<para>
|
|
Experiment around a little. It's fairly intuitive.

|
<title>Upgrading Wine with a Patch</title>
|
|
<para>
|
|
If you have the Wine source code, as opposed to a binary
|
|
distribution, you have the option of applying patches to the
|
|
source tree to fix bugs and add experimental features.
|
|
Perhaps you've found a bug, reported it to the <ulink
|
|
url="mailto:wine-devel@winehq.com">Wine mailing list</>,
|
|
and received a patch file to fix the bug. You can apply the
|
|
patch with the <command>patch</> command, which takes a
|
|
streamed patch from <filename>stdin</>:
|
|
<screen>
|
|
<prompt>$ </><userinput>cd wine</>
|
|
<prompt>$ </><userinput>patch -p0 <<replaceable>../patch_to_apply.diff</></>
|
|
</screen>
|
|
</para>
|
|
<para>
|
|
To remove the patch, use the <parameter>-R</> option:
|
|
<screen>
|
|
<prompt>$ </><userinput>patch -p0 -R <<replaceable>../patch_to_apply.diff</></>
|
|
</screen>
|
|
</para>
|
|
<para>
|
|
If you want to do a test run to see if the patch will apply
|
|
successfully (e.g., if the patch was created from an older or
|
|
newer version of the tree), you can use the
|
|
<parameter>--dry-run</> parameter to run the patch
|
|
without writing to any files:
|
|
<screen>
|
|
<prompt>$ </><userinput>patch -p0 --dry-run <<replaceable>../patch_to_apply.diff</></>
|
|
</screen>
|
|
</para>
|
|
<para>
|
|
<command>patch</> is pretty smart about extracting
|
|
patches from the middle of a file, so if you save an email with
|
|
an inlined patch to a file on your hard drive, you can invoke
|
|
patch on it without stripping out the email headers and other
|
|
text. <command>patch</> ignores everything that doesn't
|
|
look like a patch.
|
|
</para>
|
|
<para>
|
|
The <parameter>-p0</> option to <command>patch</>
|
|
tells it to keep the full file name from the patch file. For example,
|
|
if the file name in the patch file was
|
|
<filename>wine/programs/clock/main.c</>.
|
|
Setting the <parameter>-p0</> option would apply the patch
|
|
to the file of the same name i.e.
|
|
<filename>wine/programs/clock/main.c </>.
|
|
Setting the <parameter>-p1</> option would strip off the
|
|
first part of the file name and apply
|
|
the patch instead to <filename>programs/clock/main.c </>.
|
|
The <parameter>-p1</> option would be useful if you named
|
|
your top level wine directory differently to the person who sent you
|
|
the patch. For the <parameter>-p1</> option
|
|
<command>patch</> should be run from the top level wine directory.

You also need about 230 MB of available disk space for compilation.

The compiled libwine.so binary takes around 5 MB of disk space,

Stripping is not recommended, however, as you can't submit

proper crash reports with a stripped binary any more.
