(In reply to Heiko Thiery from comment #1)
Do you need to pass both DYNAMIC=something *and* SHARED=something ? This seems
a bit redundant. According to what you did in
8d38eb052e7006b6e74e9453351d7f245144481e, it seems that DYNAMIC has gone away,
and SHARED is the new variable to use ?

Your're right. That is not needed anymore. It was just a quick shot to get a
feetback. I added an updated version of the patch that removes the DYNAMIC
arguments.

I am still seeing the same error, with either version of the patch after doing
the following:

1) Deleting my build directory.
2) Checking out the source from tag 2020.11-rc1
3) In the where the source is checked out applying the patch with:
     patch -p1  -i <path to
patch>/0001-package-libcap-fix-building-on-host-package.patch
4) Copying my config file to the build directoty
5) Building buildroot

Same failure here (openSUSE Tumbleweed), both attached patches did not work...,
reverting 8d38eb052e7006b6e74e9453351d7f245144481e worked...

third iteration of the patch

I added a patch for libcap that should prevent adding the --static flag. Please
give it a try.

I also started a request to the libcap maintainer get feedback if this is the
correct way.

Thank you

That builds okay now.  Also I deployed the build to the target system, and it
runs with no problems.

Thanks,

Ian

Thanks for the feedback. I will wait for a response from libcap maintainer. And
if my patch is sufficient we can apply it to buildroot.
