Bugzilla Bug 124361

Xen can use SDL, VNC, etc. for guests.  It should probably have USE flags for
both and consequently depend on those libs.

WARNING: cannot compile statically with SDL - qemu-fast won't have a graphical

Please attach a patch for the ebuild to enable that functionality with the
appropriate USE flags. I have never used the sdl/vnc functionality and would
prefer a patch from someone who actually has it working...

xen-3.0.1-r1.patch

Crap, wrong bug.  Ignore!

(From update of attachment 80956 [edit])
not this bug

It seems like once the libraries are installed, it will automagically detect
the libraries and compile in support for it. I've made a patch, and I will
attach it as soon as I grab a clean copy of the xen-tools-3.0.2-r1 ebuild...

VNC/SDL/FMOD Patch

This adds sdl/vnc/fmod support to xen-tools. Adding mingw32 would be kind of
pointless.

SDL/VNC/FMOD patch for xen-tools

This patch actually works without replacing everything with spaces! (That's why
you never copy and paste anything that has tabs in it..)

Created an attachment (id=91023) [edit]
USE-based VNC and SDL support in xen-tools

USE-based dependencies are only half the solution, as ./configure 's
autodetection needs to be overridden as well.

Both app-emulation/xen-tools-3.0.2-r1.ebuild and the patch in attachment 90861 [edit]
allow xen-tools to autodetect the presence of SDL and build against it, which
results in incorrect behaviour when SDL is installed but the user doesn't wish
xen-tools to be built with SDL support. The same is true for VNC.

fmod support looks broken in the copy of qmeu bundled with xen-tools
(fmodaudio.c is missing, at the very least), and no-one appears to be using it
anyway (based on searches of the xen-users and xen-devel mailing lists, along
with Google searches).

Please test this patch, as I do not currently have access to a suitable setup
for complete testing.

Hello,

I tried the patch Xen-tools will compile but must we also rebuild xend?

Do you have a Intel VT to get a working Windows in your vm?

R. R.

Hello again,

SdL seems not to work.

with both (with patch and without)

I can't start Guest Image which needs SDL Support

I have a VT enabled CPU and a working image. But with gentoo it always has the
B State in xentop

Regards Roland

I've added the patch to portage.
