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 \
$(INTERMEDIATE)\lib\rtl\access.o \
$(INTERMEDIATE)\lib\rtl\acl.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 żbug? does not appear even when exists
Am I missing something here? How can It be solved, any clues?
