(please also respond to me since I can't seem to get on this list).
I want to link a ppc-aix file to an absolute address (against a running
program)

Here's the program:

int foobar(void)
{
        extern int a;
        return a;
}

a is an symbol in the program...

Here's the command line:
ld  -o lcm.so -e foobar -Ttext 0x20000a88 -Tdata 0x20000ad0 -Tbss 0x20000af0 -N b.o symbols

Here's the symbols file:
(gdb) shell cat symbols
a = 0x20000a70;
printf_indirect = 0x20000908;

For information, here's the output of objdump -x:
1 :leisner@gnu; objdump -x b.o

b.o:     file format aixcoff-rs6000
b.o
architecture: rs6000:6000, flags 0x00000031:
HAS_RELOC, HAS_SYMS, HAS_LOCALS
start address 0x00000000

In this part of xcofflink.c, its preducing an error:

At line 5518, sec == sec->output_section and sec->name = "*ABS*", hence
the link fails...

Ideas?  I'm not a bfd/xcoff expert yet...
