2.6. Getting Wine Source Code from CVS

The official web page for Wine CVS is http://www.winehq.com/dev.html.

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 CVSROOT environment
variable. You also have to log in anonymously to the wine CVS server. In bash,
it might look something like this:

$ export CVSROOT=:pserver:cvs@cvs.winehq.com:/home/wine
$ cvs login
Password: cvs
$ cvs checkout wine
    

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:

$ cvs -dP update
      

cvs update works from inside the source tree. You don't need the CVSROOT
environment variable to run it either. You just have to be inside the source
tree. The -d and -P options make sure your local Wine tree directory structure
stays in sync with the remote repository.

After you've made changes, you can create a patch with cvs diff -u, which sends
output to stdout (the -u controls the format of the patch). So, to create an
my_patch.diff file, you would do this:

$ cvs diff -u > my_patch.diff
      

You can call cvs diff from anywhere in the tree (just like cvs update), and it
will always grab recursively from that point. You can also specify single files
or subdirectories:

$ cvs diff -u dlls/winaspi > my_aspi_patch.diff
      

Experiment around a little. It's fairly intuitive.
