I tried building the yocto. All QT source files are added in recipe folder in custome layer.
while bitbake it will throw the error regarding glib-2.0 development package not found. but the package is installed.

Hi @sanket_1989,

Thanks for writing to Toradex community.

From question, I am not sure which image you are trying to build using yocto.
I assume you wanted to use qt for your application/product development. I will suggest you to check below article, we provide tdx-reference-multimedia-image which do provide qt support. Please build tdx-reference-multimedia-image first and then customise as per your requirement.

If you get error while building reference image please share complete steps and error in text format to further check.

Best Regards

Hi @Srivathsan,

Unfortunately with this information it is difficult to provide any valuable comment. Looking at error seems like recipe is trying to install library but path for same is not defined.

Kindly share details asked previously.
Additionally this seems to be custom recipe, so to provide any help here with error please share all changes you have made along with other details.

Best Regards

Hi @Srivathsan,

Thanks for sharing details.

It is custom recipe to compile qt application and error shows, this try to install binaries to non existence directory.
I will suggest to look at demo application recipe which we have used in reference-multimedia-image. Adapt your recipe and check.

Alternatively do check below article for more detail
