""" libmpathpersist.so seems to miss a few of it's own symbols, like free_pathvec. And a few of devmapper symbols. To make underlinking errors more visible try to build sys-fs/multipath-tools with LDFLAGS=-Wl,--no-undefined I think the problem here is the ordering of object files and library files: """ x86_64-pc-linux-gnu-gcc -Wl,-O1 -Wl,--as-needed -Wl,-O1 -Wl,--as-needed -Wl,-z,relro -Wl,-z,now -shared -lpthread -ldevmapper -ldl -L../libmultipath -lmultipath -L../libmpathcmd -lmpathcmd -Wl,-soname=libmpathpersist.so.0 -o libmpathpersist.so.0 mpath_persist.o mpath_updatepr.o mpath_pr_ioctl.o """ For some linkers order matters: linked files should be passed in order of dependencies. Usually it is: $(LDFLAGS) $(OBJECTS) $(LIBS). Here we see $(LDFLAGS) $(LIBS) $(OBJECTS). Assigning to base-system@ to fix underlinking. Please file a separate bug to make qemu less automagic against sys-fs/multipath-tools.
