[Buildroot] [PATCH 01/12] xdriver_xf86-video-vmware: only avaiblable on x86

[Jérôme Pouiller]

... since BR2_PACKAGE_MESA3D_GALLIUM_DRIVER_SVGA is only available on x86.

Fix warnings like:
  warning: (BR2_PACKAGE_XDRIVER_XF86_VIDEO_VMWARE) selects
  BR2_PACKAGE_MESA3D_GALLIUM_DRIVER_SVGA which has unmet direct dependencies
  (BR2_PACKAGE_MESA3D && (BR2_i386 || BR2_x86_64))

[Buildroot] [PATCH 11/12] directfb: allow SVG support

[Jérôme Pouiller]

DirectFB SVG support rely on Cairo and Cairo depends on DirectFB.

Since Cairo DirectFB backend is marked as experimental, this patch choose to
disable this backend when DirectFB SVG support is enable.

In add, this patch may solve some tricky situations between DirectFB and Cairo
(see http://sysmic.org/~jezz/results/c2f11fc0) and improve build reproducibility.

[Buildroot] [PATCH 12/12] libffi and python: need threads support

libffi depends on pthreads.

Python depends on libffi (it can provide a builtin libffi, but also depends on
pthreads). Thus this patch also disable Python support if toolchain is compiled
w/o treads support.

The user typically cannot do anything about the MMU dependency, so we
don't add it to the comment line (but do make the comment depend on MMU
so it's only shown for people who can use it).

Committed with that fixed, thanks.

cairo depends on BR2_ARCH_HAS_ATOMICS, so this should also do so.

I suspect this also needs the SVG backend of cairo. From config.log:

configure:19926: checking for libsvg-cairo >= 0.1.6
configure:19936: result: not found
configure:19939: WARNING:
*** SVG-Cairo at least 0.1.6 not found -- SVG image provider will not be built.

So it actually needs libsvg-cairo (which pulls in cairo and the svg
backend of cairo).

It also needs some help to find the cairo includes:

python is not the only user of libffi. From a quick look, they all
depends on threads except for python3, so I've made the same change to
python3.

That's wrong. Seperate 'depends on' gets ANDed together, E.G. they all
have to be true, whereas we want to display the line whenever
mmu and either !wchar OR !threads, so it should be

depends on !BR2_USE_WCHAR || !BR2_TOOLCHAIN_HAS_THREADS.

Committed with that fixed, thanks.

This seems weird. We have a no threads toolchain in our autobuilders
and it was never detected, even though I'm pretty sure libffi was built
a number of times. Do you have the configuration that exhibits the
problem?

Thanks,

I can reproduce problem using:

BR2_powerpc=y
BR2_powerpc_440=y
BR2_TOOLCHAIN_BUILDROOT_LARGEFILE=y
BR2_TOOLCHAIN_BUILDROOT_INET_IPV6=y
BR2_TOOLCHAIN_BUILDROOT_INET_RPC=y

BR2_BINUTILS_VERSION_2_24=y
BR2_GCC_VERSION_4_9_X=y
BR2_TOOLCHAIN_BUILDROOT_CXX=y
BR2_PACKAGE_LIBFFI=y

In add, I found this patch :
  http://lists.busybox.net/pipermail/buildroot/2012-November/061976.html

It is seems is had never been applied and it should solve this issue.
