Problem now is, the %{__make} fails when trying to link the final binary

That's probably due to SUSE_ASNEEDED, see
<https://build.opensuse.org/package/view_file/openSUSE:Factory/binutils/binutils-build-as-needed.diff>
and
<https://github.com/openSUSE/post-build-checks/blob/master/suse-buildsystem.sh>.
The right way to fix that is to reorder the linker command line so that
libraries appear after the objects that reference their symbols.

Thanks for the incredibly quick answer.


Your guess was correct. :-)


After manually moving -l<lib1> -l<lib2> to the end of linker command line,
linking works.


The problem that remains now is that the application in question is using
autotools/automake.

AFAIK there's now way to change the *order* of command line options/parameters.
The
Makefile.am has something like

xxx_SOURCES = a.c b.c
xxx_LDFLAGS = -m64 -lpthread ...

So I can of course change the options but not their position in the command
line.


Or is there a way to do that?

Alternatively, how do I get rid of SUSE_ASNEEDED during the build process? Is
simply
calling 'unset SUSE_ASNEEDED' in %build enough?


Thanks and regards -- Till
