Using an external linker [how ?]

[David Berthelot <davidb at Magma-DA dot COM>]

First of all thanks to Sherry for the help she offered me.
But I think I need to go a bit deeper because it doesn't solve
my problem (so far).

I want to use ild "sun incremental linker" to link the output
of g++ (on sun). But, it doesn't work ! So I describe how I proceed.

I did something like this:
> setenv PATH .:<path_to_g++_binaries>
> ln -s /<path_to_ild>/ild ld
> g++ -no-gnu-linker -c *.C
> g++ -v -no-gnu-linker -o toto.exe *.o
[... lot of debug information...]

First surprise ild is not invoked, Solaris' ld is invoked instead !
But this executable (main.exe) works fine.

then I tried just to type the line "collect2 ..." that appears in the verbose
information
produced by last line:
> collect2 ......

Then (why ?) ild is invoked this time. But the new executable doesn't work.
> main.exe
Segmentation Fault.

And a look at the crash trace (gdb):
(gdb) bt
#0  0x0 in ?? ()
#1  0x112dc in __do_global_ctors_aux ()
#2  0x1100c in _init ()

So it still seems to be related to the global constructors

So if anyone has any idea, I would be grateful since I tried everything I thought of !

Thanks,

David.
