Hi all, I downloaded the prebuilt tool chain. I can use or32-uclinux-gcc to build object file. When I use or32-uclinux-ld to link the obj file I got the problem like that Stephen@stephen ~/or32-test $ or32-uclinux-ld -o mul /opt/or32-uclinux/lib/crt0.o mul.o -lc mul.o: In function `_main': mul.o(.text+0x434): undefined reference to `_report' /opt/or32-uclinux/or32-uclinux/lib/libc.a(ultostr.o): In function `___ultostr': ultostr.o(.text+0x54): undefined reference to `___umodsi3' ultostr.o(.text+0x64): undefined reference to `___udivsi3' /opt/or32-uclinux/or32-uclinux/lib/libc.a(dtostr.o): In function `___dtostr': dtostr.o(.text+0x80): undefined reference to `___nedf2' dtostr.o(.text+0x234): undefined reference to `___eqdf2' dtostr.o(.text+0x268): undefined reference to `_(float, int, long long, double, float, short, int)' dtostr.o(.text+0x274): undefined reference to `___floatsidf' dtostr.o(.text+0x294): undefined reference to `___subdf3' dtostr.o(.text+0x2b8): undefined reference to `___muldf3' dtostr.o(.text+0x6fc): undefined reference to `___ltdf2' dtostr.o(.text+0x72c): undefined reference to `___muldf3' dtostr.o(.text+0x748): undefined reference to `___eqdf2' dtostr.o(.text+0x7b4): undefined reference to `___muldf3' dtostr.o(.text+0x7f0): undefined reference to `___ltdf2' dtostr.o(.text+0x858): undefined reference to `___muldf3' dtostr.o(.text+0x87c): undefined reference to `___ltdf2' dtostr.o(.text+0x8cc): undefined reference to `___gedf2' dtostr.o(.text+0x90c): undefined reference to `___divdf3' dtostr.o(.text+0x938): undefined reference to `___muldf3' dtostr.o(.text+0x95c): undefined reference to `___divdf3' dtostr.o(.text+0x980): undefined reference to `___gedf2' dtostr.o(.text+0x9b0): undefined reference to `___divdf3' dtostr.o(.text+0x9d0): undefined reference to `___negdf2' It seems that there are some problem on the file of libc.a. Anyone encountered problem like that? Can anyone give me idea how to fix it? Thank you very much. Best Regards, Stephen

i'm pretty sure that at least ___umodsi3 and ___udivsi3 are implemented in
libgcc.a library. if you are using gcc 3.2.3 it should be in:

/opt/lib/gcc-lib/or32-elf/3.2.3

(substitute 'elf' with apropriate target and 3.2.3 with your
compiler version)

hope that it helps!

have fun,

Hi Matjaz Breskvar, Yes, I can find the libgcc.a in the directory. But Can you tell me how to use it when I use the linker. Thank you very much.

you had:

or32-uclinux-ld -o mul /opt/or32-uclinux/lib/crt0.o mul.o -lc

(here you were linking also with libc)

you could just do:

or32-uclinux-ld -o mul /opt/or32-uclinux/lib/crt0.o mul.o \
-L/opt/lib/gcc-lib/or32-elf/3.2.3 -lgcc -lc


you welcome.

well in your case or32-elf is probably or32-uclinux:

or32-uclinux-ld -o mul /opt/or32-uclinux/lib/crt0.o mul.o \
-L/opt/lib/gcc-lib/or32-uclinux/3.2.3 -lgcc -lc
