Build failed with --imx-linux-headers-path
Hi, I'm working with an iMX8m from SolidRun;
https://www.solid-run.com/product/SRMX8QDW00D03GE008V20C0/
When following the specified configuration instructions;
./waf configure --prefix=PREFIX
Errors relating to not having a specified kernel headers path appear. So I added the following kernel headers path in the configuration;
./waf configure --prefix=PREFIX --imx-linux-headers-path=/usr/src/linux-headers-4.14.104-imx8-sr/include/
This seemed to get us a little closer, now being able to include <linux/mxcfb.h>. Soon after a load of include errors were cropping up relating to "asm" includes. In the kernel header source files, there is only an "asm-generic", so I thought I created a symlink for asm to see if this would progress things a little further. The following errors appeared in the build config log; (snippet below)
Would you be able to shed a little light on this issue?

Enabling G2D for allocation and compositor
Howdy,
I'm trying to get the G2D working for allocation, I see to enable ION in the kernel is uses
CONFIG_ION=y
CONFIG_ION_CMA_HEAP=y
in the kernel config, but I'm having a hard time finding how to get the G2D API enabled on the IMX6?
Is there a kernel config for this, or is there more to getting it enabled when building Linux from source?
Can't build ion allocator with 4.14.98_2.0.0 kernel
Hi Carlos,
This member of the struct does not exist in the mentioned kernel version, and its not filtered by IF_LINUX_VERSION_CODE ....
So it can't be built with the above mentioned kernel headers.
Just a quick question, why do you prefer ION rather than HANTRO DWL ? Just wondering.
Getting "error: ‘imx_dwl_buffer’ undeclared" when building v1.1.2
I have some toolchain named fsl-imx-wayland-glibc-x86_64-core-image-base-cortexa53-crypto-imx8mmevk-toolchain-5.10-hardknott. Sysroot has old GStreamer 1.18 , so I'm building gstreamer-imx for GStreamer 1.22.3.
I've set imx headers path to /opt/fsl-imx-wayland/5.10-hardknott/sysroots/cortexa53-crypto-poky-linux/usr/include/imx, build starts but fails with:

Could this mean that imx linux headers are too old in that toolchain?

[Support] Issue with Linux headers
if I run ./waf configure --prefix=/usr/local/ I get:
--imx-linux-headers-path is not set
Since machine (NXP i.MX 8M Mini 4xCortex-A53) runs on non-upstream kernel image ( 4.14.98-2.3.0+ #1 SMP PREEMPT Mon Nov 8 02:36:19 UTC 2021 aarch64 GNU/Linux), i.e. not Debian's one, I need to get NXP kernel headers for that version to build this library?
Are these headers freely available from "somewhere"?
Thanks!
DMABuff only works with root permissions?

I had to add user to video group to access fb0 at first, but it seems I need more permissions to utilize DMABuff on this imx8mm device..?
Or is it impossible to use this feature at all not running root?
Failing to build caused by missing header
Hello, I'm having trouble getting the libimxdmabuffer to compile for the IMX6Q as my toolchain sysroot doesn't seem to contain the linux/mxcfb.h header file. I'm wondering how to obtain this or resolve this error to get the package building? It looks like this issue had cropped up before but I couldn't find a resolution publicly.
Command being ran to build:
./waf configure --prefix=$PREFIX --imx-linux-headers-path=/usr/arm-buildroot-linux-gnueabihf/sysroot/usr/include
Error encountered:
Checking for header linux/mxcfb.h : not found
Could not find linux/mxcfb.h in path "/usr/arm-buildroot-linux-gnueabihf/sysroot/usr/include" specified by --imx-linux-headers-path
