Re: ldscripts

[Jens-Christian Lache <lache at tu-harburg dot de>]

Thank you for the hint! At the moment I use 
ld	: hello.world.c
	$(LD) -T../linker/linker.script.sc -o hello.world
$(CRTBEGIN_FILE) $(CRT0_FILE) $(LIBDIRS) hello.world.o -lgcc -lg -lc -lgcc
$(CRTEND_FILE) 

It works and a few hours ago I had my first successfull download to the
board.
It is still a bit clumsy to make first object files and than link them by
hand. I tried to use 

test	:hello.world.c
	$(CC) -g -v $(LIBDIRS) $(INCLUDEDIRS) -o hello.world.test \
	-Wl, -T$(LINKER_SCRIPT) hello.world.c

to pass the script name to the linker. It does not work. The result:

/home/hiwi/lache/tools/H-i686-pc-linux-gnu/lib/gcc-lib/arm-elf/2.95.2/collect2
-X -o hello.world.test
/home/hiwi/lache/tools/H-i686-pc-linux-gnu/lib/gcc-lib/arm-elf/2.95.2/crtbegin.o
/home/hiwi/lache/tools/H-i686-pc-linux-gnu/lib/gcc-lib/arm-elf/2.95.2/crt0.o
-L/home/hiwi/lache/tools/H-i686-pc-linux-gnu/lib/gcc-lib/arm-elf/2.95.2

-L/home/hiwi/lache/tools/H-i686-pc-linux-gnu/lib/gcc-lib/arm-elf/2.95.2
-L/home/hiwi/lache/tools/H-i686-pc-linux-gnu/arm-elf/lib  /tmp/ccVI0xa0.o
-lgcc -lg -lc -lgcc
/home/hiwi/lache/tools/H-i686-pc-linux-gnu/lib/gcc-lib/arm-elf/2.95.2/crtend.o
-T/home/hiwi/lache/c/linker/linker.script.sc
/home/hiwi/lache/tools/H-i686-pc-linux-gnu/arm-elf/bin/ld: cannot open
: No such file or directory
collect2: ld returned 1 exit status

This is the last stage of the compiling process. If I would build the
object-files and than link them by hand with the above comment 
(replacing /tmp/ccVI0xa0.o with hello.world.o) it would link it!!
How can I tell the linker several options? 
(-Wl, -T$(LINKER_SCRIPT),--verbose didn't work)
