shadow 4.14.x adds a number of libraries it dynamically links with (md, bsd, attr). This causes troubles in setscene tasks where shadow executables are used (such as useradd), as pulling in the needed dynamic libraries needs unpleasant special-casing. Signed-off-by: Alexander Kanavin <alex@linutronix.de> --- v2: patch only Makefiles that produce executables and libshadow.a (that executables all statically link with), do not patch libsubid/Makefile, as patching in .a linking can clash with producing dynamic libraries. libsubid is used only in getsubids executable, which is not used in setscene user management (or anywhere else from what I can see). --- meta/conf/distro/include/no-static-libs.inc | 5 +++++ meta/recipes-extended/shadow/shadow.inc | 9 +++++++++ 2 files changed, 14 insertions(+)
