[Buildroot] Qt5 and gpu-viv-bin-mx6q problem

[Buildroot] Qt5 and gpu-viv-bin-mx6q problem

[Massimiliano Marretta]

Dear,

I have some problem to obtain a buildroot with Qt5 and gpu-viv-bin-mx6q.
Where is the correct combination of toolchain and floating point strategy ?

I try some combination of toolchains with the last stable version of
buildroot (2013.11).

- If I use the last codebanch toolchain the gpu-viv-bin-mx6q examples and
the Qt5 qmlscene crash with segmentation fault.
- If I use the last buildroot linaro toolchain 4.8-2013.09, the system not
start because the kernel is to old ( 3.0.35 ).
- If I use the toolchain linaro-4.7-2013.01 the Qt5 qmlscene exit without
message and gpu-viv-bin-mx6q examples not start with the message program
not found.

Best Regards,
Massimiliano Marretta

 That's the combination I used successfully in the past:

BR2_TOOLCHAIN_EXTERNAL_CODESOURCERY_ARM201109=y
BR2_PACKAGE_GPU_VIV_BIN_MX6Q=y
BR2_PACKAGE_QT5BASE_LINUXFB=y
BR2_PACKAGE_QT5BASE_DIRECTFB=y

 This was with an old buildroot however (2012.08 with a lot of additional
patches).

 I think that gpu-viv-bin-mx6q are softfp libraries, so they won't work
with Linaro (hardfp) toolchains. I'm surprised that qt5 builds at all in
that case...

The latest patches (on -next) allow for either hardfp or softfp:

 Yes, but the OP mentioned that he uses 2013.11 in the text you snipped.

 Arnout

Oops.

[Buildroot] Qt5 and gpu-viv-bin-mx6q problem

[Massimiliano Marretta]

Dear Eric,

many thanks for the suggestions.

I use the wandboard kernel version 3.0.35_4.1.0.
I have apply your patch in my buildroot version and now with the linaro hf
toolchain the gpu-viv-bin-mx6q examples work correctly.
Unfortunately qmlscene exit without any message (both console and fb). Qt5
work only with sf ?

Why the patch is not present in the last buildroot version 14.02 ?

Regards,
Massimiliano.

[Buildroot] Qt5 and gpu-viv-bin-mx6q problem

Hi Massimiliano,

Unfortunately, saying "3.0.35" isn't specific enough. The first
few releases (what Freescale referred to as 1.0.0, 1.1.0, and 4.0.0)
won't support the badly-named 3.5.7-1.0.0 GPU binaries.

For that, you need the updates that came with the 3.0.35_4.1.0
release.

Clear, huh?

If you have a commit id in your source tree for the last Freescale
update we (or you) can likely pin-point it with "git branch --contains".

If you started with one of the older branches, it's likely that
your patches will forward-port pretty easily. None of the 3.0.35
releases from Freescale had any major re-structuring.

Regards,


Eric

Can I use the gpu-viv-bin-mx6q-3.5.7-1.0.0-hfp.bin with the kernel version
3.0.35  ?
