[Bug 1048446] Re: Flash requires hal for video DRM

[Tommy Trussell]

Was reading an OpenSUSE discussion of this issue that contained two
potentially helpful links....here are the links:

The following RedHat bug includes an analysis of what Flash is using hal
for:

https://bugzilla.redhat.com/show_bug.cgi?id=786656

The following Q&A includes info about building a version of hal in
gentoo with minimal dependencies just for the purpose of working with
Adobe Flash. http://superuser.com/questions/415238/protected-flash-
video-requires-hal-on-gentoo

(Hmmm... makes me think someone could build a special flash-hal package
that can be a dependency of Adobe Flash but conflict with "real" hal
JUST for the purpose of allowing drm content.)

In case the superuser.com item disappears here is what the two answers say:

HAL works on top of udev; it has never been "replaced by" it completely; those features that were can be disabled in hal (such as ACL management). There shouldn't be any conflicts as long as Flash Player is the only user of HAL.

For anyone in my shoes who needs to get this installed, grawity's comments to his answer hold the key on how to do it. For an explicit step-by-step:

Step 1: Grab the code

# git clone http://cgit.freedesktop.org/hal-info/
# git clone http://cgit.freedesktop.org/hal/

Step 2: Install hal-info

# cd hal-info
# ./autogen
# make && make install
# cd ..

Step 3: Fix the hal code

To do this, replace all instances of #include <glib/gmain.h> with
#include <glib.h>. You can do that with a command like:

# find hal -name "*.c" -print|xargs sed -i 's/#include <glib\/gmain\.h>/#include <glib\.h>/g'
For some reason, that missed one reference (I'm not really a regexp / sed guru) so I just did a grep -r "#include <glib/gmain.h>" * and fixed it manually.

Step 4: Install hal

# cd hal
# ./autogen.sh --disable-policy-kit
# make && make install

Step 5: Don't forget the dbus config!

# cp hal.conf /etc/dbus-1/system.d/

That's it! Now just run it with hald
