A: 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.
To check out the HEAD version of the core, use
cvs -d:pserver:anoncvs@anoncvs.freedesktop.org:/cvs/gstreamer co gstreamerThis 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.
The modules page has a list of active ones together with a short description.
A: 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:
your desired unix username
your full name
your e-mail address
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 .ssh/id_dsa.pub
your GPG fingerprint. This would allow you to add and remove ssh keys to your account.
Q: I ran autogen.sh, but it fails with aclocal errors. What's wrong ?
+ 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 failedWhat's wrong ?
A: 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.
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.
You can do three things to fix this :
install automake in the same prefix as libtool
force use of the automake installed in the same prefix as libtool by using the --with-automake option
figure out what prefix libtool has been installed to and point aclocal to the right location by running
export ACLOCAL_FLAGS="-I $(prefix)/share/aclocal"where you replace prefix with the prefix where libtool was installed.
A: "-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.
"-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.
If for any reason you want to bypass these flags and you are certain it's the right thing to do, you can run
make ERROR_CFLAGS=""to clear the CFLAGS for error checking.
