[ros-dev] Linking problems

[Marc Piulachs]

Does the order of .o files matter when linking against a static library? 

 

I ask this because I'm having problems linking ntoskrnl with rtl
dependending on the order of object files when compiling rtl. For example on
the rbuild generated makefile.auto the order of .o files is :

 

rtl_OBJS := \

            $(INTERMEDIATE)\lib\rtl\austin\avl.o \

            $(INTERMEDIATE)\lib\rtl\austin\tree.o \

            $(INTERMEDIATE)\lib\rtl\access.o \

            $(INTERMEDIATE)\lib\rtl\acl.o \

            $(INTERMEDIATE)\lib\rtl\atom.o \

            $(INTERMEDIATE)\lib\rtl\bitmap.o \

            $(INTERMEDIATE)\lib\rtl\bootdata.o \

            $(INTERMEDIATE)\lib\rtl\compress.o \

            $(INTERMEDIATE)\lib\rtl\condvar.o \

            $(INTERMEDIATE)\lib\rtl\crc32.o \

            $(INTERMEDIATE)\lib\rtl\critical.o \

            $(INTERMEDIATE)\lib\rtl\dbgbuffer.o \

            $(INTERMEDIATE)\lib\rtl\debug.o \

            $(INTERMEDIATE)\lib\rtl\dos8dot3.o \

            $(INTERMEDIATE)\lib\rtl\encode.o \

            $(INTERMEDIATE)\lib\rtl\env.o \

            $(INTERMEDIATE)\lib\rtl\error.o \

            $(INTERMEDIATE)\lib\rtl\exception.o \

            $(INTERMEDIATE)\lib\rtl\generictable.o \

            $(INTERMEDIATE)\lib\rtl\handle.o \

            $(INTERMEDIATE)\lib\rtl\heap.o \

            $(INTERMEDIATE)\lib\rtl\image.o \

            $(INTERMEDIATE)\lib\rtl\message.o \

            $(INTERMEDIATE)\lib\rtl\largeint.o \

            $(INTERMEDIATE)\lib\rtl\luid.o \

            $(INTERMEDIATE)\lib\rtl\network.o \

            $(INTERMEDIATE)\lib\rtl\nls.o \

            $(INTERMEDIATE)\lib\rtl\path.o \

            $(INTERMEDIATE)\lib\rtl\ppb.o \

            $(INTERMEDIATE)\lib\rtl\process.o \

            $(INTERMEDIATE)\lib\rtl\propvar.o \

            $(INTERMEDIATE)\lib\rtl\qsort.o \

            $(INTERMEDIATE)\lib\rtl\random.o \

            $(INTERMEDIATE)\lib\rtl\rangelist.o \

            $(INTERMEDIATE)\lib\rtl\registry.o \

            $(INTERMEDIATE)\lib\rtl\res.o \

            $(INTERMEDIATE)\lib\rtl\resource.o \

            $(INTERMEDIATE)\lib\rtl\sd.o \

            $(INTERMEDIATE)\lib\rtl\security.o \

            $(INTERMEDIATE)\lib\rtl\sid.o \

            $(INTERMEDIATE)\lib\rtl\sprintf.o \

            $(INTERMEDIATE)\lib\rtl\srw.o \

            $(INTERMEDIATE)\lib\rtl\swprintf.o \

            $(INTERMEDIATE)\lib\rtl\splaytree.o \

            $(INTERMEDIATE)\lib\rtl\thread.o \

            $(INTERMEDIATE)\lib\rtl\time.o \

            $(INTERMEDIATE)\lib\rtl\timezone.o \

            $(INTERMEDIATE)\lib\rtl\timerqueue.o \

            $(INTERMEDIATE)\lib\rtl\unicode.o \

            $(INTERMEDIATE)\lib\rtl\unicodeprefix.o \

            $(INTERMEDIATE)\lib\rtl\vectoreh.o \

            $(INTERMEDIATE)\lib\rtl\version.o \

            $(INTERMEDIATE)\lib\rtl\workitem.o \

            $(INTERMEDIATE)\lib\rtl\i386\debug_asm.o \

            $(INTERMEDIATE)\lib\rtl\i386\except_asm.o \

            $(INTERMEDIATE)\lib\rtl\i386\except.o \

            $(INTERMEDIATE)\lib\rtl\i386\random_asm.o \

            $(INTERMEDIATE)\lib\rtl\i386\rtlswap.o \

            $(INTERMEDIATE)\lib\rtl\i386\rtlmem.o \

            $(INTERMEDIATE)\lib\rtl\i386\res_asm.o \

            $(INTERMEDIATE)\lib\rtl\i386\thread.o \

 

Using this order rtl will compile and ntoskrnl can be linked without
problems but If the order is changed to ASMs on top (the order present in
rtl.rbuild):

 

rtl_OBJS := \

            $(INTERMEDIATE)\lib\rtl\i386\debug_asm.o \

            $(INTERMEDIATE)\lib\rtl\i386\except_asm.o \

            $(INTERMEDIATE)\lib\rtl\i386\except.o \

            $(INTERMEDIATE)\lib\rtl\i386\random_asm.o \

            $(INTERMEDIATE)\lib\rtl\i386\rtlswap.o \

            $(INTERMEDIATE)\lib\rtl\i386\rtlmem.o \

            $(INTERMEDIATE)\lib\rtl\i386\res_asm.o \

            $(INTERMEDIATE)\lib\rtl\i386\thread.o \

            $(INTERMEDIATE)\lib\rtl\austin\avl.o \

            $(INTERMEDIATE)\lib\rtl\austin\tree.o \

You will get linking errors , this error looks wired to me . In the rbuild
generated file the .asm files generating this problem will be added to the
end of the list because they are inside an If condition (ARCH=i386) so this
¿bug? does not appear even when exists

 

Am I missing something here? How can It be solved, any clues?
