How do I check out GStreamer from CVS ?

<answer>

<para>
|
|
GStreamer is hosted on Freedesktop.org. GStreamer consists of various parts.
|
|
In the beginning, you will be interested in the "gstreamer" module, containing
|
|
the core, and "gst-plugins", containing the basic set of plugins.
|
|
</para>
|
|
<para>
|
|
To check out the HEAD version of the core, use
|
|
<programlisting>
|
|
cvs -d:pserver:anoncvs@cvs.freedesktop.org:/cvs/gstreamer co gstreamer
|
|
</programlisting>
|
|
This will create a directory "gstreamer" in your current directory.
|
|
If you want to get another module, replace the last "gstreamer" with the
|
|
name of the module.

How do I get developer access to GStreamer CVS ?
|
|
</para>

</question>

<answer>

<para>
|
|
If you want to gain developer access to GStreamer CVS, you should ask for
|
|
it on the development lists, or ask one of the maintainers directly.
|
|
If you are not already a registered developer with a user account on
|
|
Freedesktop.org, You will then have to provide them with:
|
|
<orderedlist>
|
|
<listitem><para>your desired unix username</para></listitem>
|
|
<listitem><para>your full name</para></listitem>
|
|
<listitem><para>your e-mail address</para></listitem>
|
|
<listitem><para>a copy of your public sshv2 identity.
|
|
If you do not have this yet, you can generate it by running
|
|
"ssh-keygen -t dsa". The resulting public key
|
|
will be in <filename>.ssh/id_dsa.pub</filename></para></listitem>
|
|
<listitem><para>(optionally) your GPG fingerprint. This would allow you to
|
|
add and remove ssh keys to your account.
|
|
</para></listitem>
|
|
</orderedlist>
|
|
|
|
MAKE SURE you ATTACH these files to your mail, not paste them, because
|
|
then the output is useless.

<question id="autogen-libtool">
|
|
<para>
|
|
I ran autogen.sh, but it fails with something like this:
|
|
<programlisting>
|
|
+ running aclocal -I m4 -I common/m4 ...
|
|
aclocal: configure.ac: 8: macro `AM_DISABLE_STATIC' not found in library
|
|
aclocal: configure.ac: 17: macro `AM_PROG_LIBTOOL' not found in library
|
|
aclocal failed
|
|
</programlisting>
|
|
What's wrong ?
|
|
</para>
|
|
</question>
|
|
|
|
<answer>
|
|
<para>
|
|
aclocal is unable to find two macros installed by libtool in a file called
|
|
libtool.m4. Normally this would indicate that you don't have libtool, but
|
|
that would mean autogen.sh would have failed on not finding libtool.
|
|
</para>
|
|
<para>
|
|
It is more likely that you installed automake (which provides aclocal) in
|
|
a different prefix than libtool. You can check this by examining in what
|
|
prefix both aclocal and libtool are installed.
|
|
</para>
|
|
<para>
|
|
You can do three things to fix this :
|
|
<orderedlist>
|
|
<listitem><para>install automake in the same prefix as libtool</para></listitem>
|
|
<listitem><para>force use of the automake installed in the same prefix as libtool
|
|
by using the --with-automake option</para></listitem>
|
|
<listitem><para>figure out what prefix libtool has been installed to and point
|
|
aclocal to the right location by running
|
|
<programlisting>
|
|
export ACLOCAL_FLAGS="-I $(prefix)/share/aclocal"
|
|
</programlisting>
|
|
where you replace prefix with the prefix where libtool was installed.
|
|
</para></listitem>
|
|
</orderedlist>

<question id="werror">

Why is "-Wall -Werror" being used ?
|
|
</para>
|
|
</question>
|
|
|
|
<answer>
|
|
<para>
|
|
"-Wall" is being used because it finds a lot of possible problems with code.
|
|
Not all of them are necessarily a problem, but it's better to have the compiler
|
|
report some false positives and find a work-around than to spend time
|
|
chasing a bug for days that the compiler was giving you hints about.
|
|
</para>
|
|
<para>
|
|
"-Werror" is turned off for actual releases. It's turned on by default for
|
|
CVS and prereleases so that people actually notice and fix problems found by
|
|
"-Wall". We want people to actively hit and report or fix them.
|
|
</para>
|
|
<para>
|
|
If for any reason you want to bypass these flags and you are certain it's the
|
|
right thing to do, you can run
|
|
<programlisting>make ERROR_CFLAGS="</programlisting>
|
|
to clear the CFLAGS for error checking.
