[Buildroot] Freescale specific kernel header to compile imx-lib

[Buildroot] Freescale specific kernel header to compile imx-lib

[Alexandre Schnegg]

Hello,

I use an APF27 board from Armadeus, running an i.MX27. The latest BSP
provides by Armadeus uses Buildroot 2013.05-00008-gc3f1103. In the package
selection I choose imx-lib, which requires some specific header, as said in
the help of the package:


 BR2_PACKAGE_IMX_LIB:


? 


  ?


? 


  ? Library of userspace helpers specific for the Freescale i.MX


? 


  ? platform. It wraps the kernel interfaces for some i.MX platform


? 


  ? specific drivers. It requires a kernel that includes the i.MX


? 


  ? specific headers to be built.


? 


  ?


? 


  ? This library is provided by Freescale as-is and doesn't have


? 


  ? an upstream.


? 


  ?


? 


  ? Symbol: BR2_PACKAGE_IMX_LIB [=y]


? 


  ? Type  : boolean


? 


  ? Prompt: imx-lib


? 


  ?   Defined at package/imx-lib/Config.in:4


? 


  ?   Depends on: BR2_LINUX_KERNEL [=y] && BR2_arm [=y]


? 


  ?   Location:


? 


  ?

-> Package Selection for the target


? 


  ?  

-> Libraries


? 


  ?    

-> Hardware handling


? 


  ?   Selected by: BR2_PACKAGE_GST_FSL_PLUGINS [=n] && BR2_LINUX_KERNEL [=y]
&& BR2_arm [=y] && \               

? 

	

  ? BR2_PACKAGE_GSTREAMER [=n] || BR2_PACKAGE_IMX_TEST [=n] ||
BR2_PACKAGE_LIBFSLVPUWRAP [=y] && \              

? 

	

  ? BR2_LINUX_KERNEL [=y] && BR2_arm [=y]

 My question is : can I get this header on my cross-compile machine running
Ubuntu 13.04 or am I forced to use a Freescale BSP and do a native
compilation ?

 Thanks in advance

 Regards

Alexandre Schnegg

You simply need to tell Buildroot to build a Linux kernel that is
Freescale specific, and therefore contains these headers. The imx-lib
package will look directly into the kernel sources for those i.MX
specific headers.

[Buildroot] Freescale specific kernel header to compile imx-lib

[Alexandre Schnegg]

Thank you for your response.

I can give you some more details.

When I only select the package "imx-lib", compilation is ok. But when I also
select the package "gst-fsl-plugins", I have this issue:

checking whether -lc should be explicitly linked in... no
checking dynamic linker characteristics... GNU/Linux ld.so
checking how to hardcode library paths into programs... immediate
checking whether stripping libraries is possible... no
checking if libtool supports shared libraries... yes
checking whether to build shared libraries... yes
checking whether to build static libraries... yes
checking vpu_lib.h usability... no
checking vpu_lib.h presence... no
checking for vpu_lib.h... no
configure: error: lib_vpu is required, consider installing imx-lib
make[1]: ***

make: *** [all] Error 2
schnegg at ubuntu:~/Documents/armadeus$ make menuconfig

It's seems the "imx-lib" isn't built. 

Do you have an idea what's wrong ?

Armadeus is making some fairly major changes to the Buildroot packages,
so I'm not sure whether the help we can provide will be 100% accurate.

<rant>

I've asked gazillions of times the Armadeus people to push their
changes upstream, I'm on their IRC channel to help them to do so if
they need help. But over the past 4+ years, they only contributed 25
patches to Buildroot, and have kept most of their Buildroot changes out
of tree. Seems like they prefer to update their stack of patches over
and over and over again.

The libfslvpuwrap package has a dependency on imx-lib, so it should get
built before:

LIBFSLVPUWRAP_DEPENDENCIES += imx-lib

Can you restart your build from scratch (make clean; make), and log the
entire build output a file:

	make 2>&1 | tee build.log

And then see if imx-lib is properly built before libfslvpuwrap. If
that's the case, then you should look if a vpu_lib.h file was installed
somewhere. Depending on that, we'll see what's going on: either it has
been installed but libfslvpuwrap isn't looking for it at the right
place, or it hasn't been installed.

Best regards,

Thomas

[Buildroot] Freescale specific kernel header to compile imx-lib

[Alexandre Schnegg]

Dear Thomas,

I'm not familiar with the mailing list usage so if I make another mistake please tell me.

By the way, I have got an answer from Armadeus :

" current (recent) gstreamer-fsl-plugins only works with recent imx-lib packages which doesn't seems to work on i.MX27 anymore... (tested on APF51 only)"

They have a home made way to use the hardware acceleration, I will test it.

Thank you for your help.

Dear Alexandre Schnegg,

Can you please reply to the Buildroot mailing list (possibly with me in
Cc) and not just to me directly? Whenever I provide free support, I'd like it to be public and archived in the mailing list.

Thanks!

Thomas
