Not able to build Soft ISP demo

[Tong]

Hi,

I am trying NXP Soft ISP demo by following https://github.com/NXPmicro/gtec-demo-framework/blob/master/Doc/Setup_guide_yocto.md , but build fails.

First of all, I build SDK from source tree with following command, my source tree's target machine is i.MX8mn

bitbake image -c populate_sdk

then I install the SDK, and build Soft ISP demo:

. environment-setup-aarch64-poky-linux
cd ~/gtec-demo-framework
source prepare.sh
cd DemoApps/OpenCL/SoftISP
FslBuild.py --Variants [WindowsSystem=Wayland]

The error is:

../../../../DemoFramework/FslDemoApp/Util/Graphics/source/FslDemoApp/Util/Graphics/Service/ImageLibrary/STBImageWriteLib.cpp:34:10: fatal error: stb_image_write.h: No such file or directory
34 | #include <stb_image_write.h>
| ^~~~~~~~~~~~~~~~~~~

What is wrong with my step and how to fix it?

Thanks.

as I known, current bsp includes ISP demo already, I suggest that you can build yocto bsp directly, the demo under /opt/imx-gpu-sdk/OpenCL/SoftISP
