Yocto - Files/directories were installed but not shipped in any package

Question

I'm using Yocto to install clBLAS library (https://github.com/clMathLibraries/clBLAS) using the recipe https://github.com/CogentEmbedded/meta-opencl/blob/master/meta-ocl-common/recipes-graphics/clblas/clblas_git.bb

But I'm getting the below warning everytime & .so file is not present in the built image.

WARNING: QA Issue: clblas: Files/directories were installed but not shipped in any package:
  /usr/lib
  /usr/lib/libclBLAS.so.2.12.0
  /usr/lib/libclBLAS.so.2

  /usr/lib/cmake/clBLAS/clBLASTargets.cmake
  /usr/lib/cmake/clBLAS/clBLASConfig.cmake
Please set FILES such that these items are packaged. Alternatively if they are unneeded, avoid installing them or delete them within do_install.
clblas: 14 installed and not shipped files. [installed-vs-shipped]

How to overcome this warning & make the .so file present in the target's /usr/lib folder?

Answer 1

Add below lines to your clblas_git.bb

 FILES_${PN} += "${libdir}/*"
 FILES_${PN}-dev = "${libdir}/* ${includedir}"

For good explanation you will get it here

Thanks@ Siva.v , could you please tell me why we need to add include dir – Lakh

The answer isn't a really good one and certainly not perfect. It is treating only the symptoms, particularly INSANE_SKIP means the test will be skipped, but the underlying problem will stay. And correct file packaging should happen automatically. If you can run 'bitbake -e clblas' and post the output (e.g. to pastebin), we might be able to better diagnoze why it isn't working by default. – Babbage

It will be helpful if someone could explain how this solution works – Biscuit

Answer 2

If you are using new version of yocto this will help:

FILES:${PN} ="name of the dirs is not shipping";

In old versions it is FILES_${PN}.

That was my case, good point! thanks – Boylan

Answer 3

The problem is that multilib is not considered correctly during build, looking at cmake files in clBLAS, its using CMake variable for constructing multilib path SUFFIX_LIB and yocto recipe is setting it to be empty here however its not encoding the yocto logic for multilib paths. A potential fix would be in recipe as below
