Getting "error: ‘imx_dwl_buffer’ undeclared" when building v1.1.2

[Talkless]

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?

Right, it seems I can build 1.0.1 on that sysroot, not the latest...

[dv1]

This was a typo in 1.1.2, fixed in commit 41825b1 . I will release a version 1.1.3 soon that includes this. Until then, that commit can be put on top of 1.1.2.

[Talkless]

Thanks @dv1, it builds with fix.
