@jschlatow: We experienced the "--whole-archive" problem with libgcc.a again with shared libraries and Qt5, same as with cmake. So 8f3af6e is a necessary follow up.

@ssumpf shared libraries in the genode mk link with libgcc outside of --whole-archive --start-group ... --end-group --no-whole-archive in repos/base/mk/lib.mk. Can you tell why it is not needed there but here? Note, I also checked a build of app/texedit, which builds libQt5Gui.lib.so etc.

@chelmuth: Because there is only one archive (libgcc.a) there.

From the ld man page of --start-group

The specified archives are searched repeatedly until no new undefined references  are  created.
Normally,  an  archive  is  searched only once in the order that it is specified on the command
line.
