Dear Michael,


Thank you for your reply.

That did the trick.

As I am not crosscompiling I am wondering, why this needs to be done.

Is LibreOffice using it’s own build script? I built upstream NSS with 
NSPR – I think all the components – with `make nss_build_all` without 
any problems.


Kind regards,

Paul
