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

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

Do you have an idea what's wrong ?

Dear 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.

Best regards,

Thomas
