Error: Flag --keep-global-symbol doesnt work ??

[Heiko_Elger]

Hello,

I want to use the -G (--keep-global-symbol, --keep-global-symbols) and I think
it doens work.

I tried with version 2.12.90 (cygwin version).

---- snip: test.c  --------------

int global_i;
int f_global(void)
{
   return 1;
}

--------end nip -------------
gcc -g -O0 -c test.c -o test.o

nm test.o

00000000 b .bss
00000000 d .data
00000000 N .stab
00000000 N .stabstr
00000000 t .text
00000000 t ___gnu_compiled_c
00000000 T _f_global
00000010 C _global_i
00000000 t gcc2_compiled.

the commands: objcopy -G _f_global -G _global_i test.o test.new.o
                       nm test.new.o

have the same output as with test.o.

00000000 b .bss
00000000 d .data
00000000 N .stab
00000000 N .stabstr
00000000 t .text
00000000 t ___gnu_compiled_c
00000000 T _f_global
00000010 C _global_i
00000000 t gcc2_compiled.


Perhaps its a problem of nm.
I tried to link test.o with another object which have references to f_global and
global_i with no errors.

So I think that it will not work!


Can you please give me a hint?



Mit freundlichen Gruessen
