Hi,

I've got some strange behavior when I want to link some libraries
in order to create an executable file.

I've created all my libraries with the command ar (with this following options
rcvs). When I want to link all my libraries to create the program file,
I've got a lot of unjustificated unresolved external in one of my libraries
(called libtoolbox.a). After I tried to make libtoolbox.a with ld (with
options -r -o libtoolbox.a), and all my previous unresolved external messages
disappeared, but a new one appeared in another object file.
I figure out the problem and it was another library (called libstuff.a), so
like libtoolbox.a I made again libstuff.a with ld. Finally, I didn't get any
unresolved external, but the linker told me I've got two definitions of the
same feature: _bss_start__ and _bss_end__, but there are not mines.

Below, this is the output of the linker:
<<
libtoolbox.a(.bss+0x400000):draw.c: multiple definition of `_bss_start__'
libstuff.a(.data+0x400000):reference.c: first defined here
libtoolbox.a(.bss+0x401364):draw.c: multiple definition of `_bss_end__'
libstuff.a(.data+0x400000):reference.c: first defined here
make: *** [my_program.exe] Error 1
>>

Is there someone who knows how to solve my problem?

Thanks in advance

Manu
