I think that did the trick.  I downloaded and built
the gnu libtools for Solaris 8 and used its linker
instead of the native linker, with the --whole-archive
option, and it doesn't seem to need libstdc++.so
anymore.  Thanks for the help, I owe you a sixpack :)

No, the Solaris /bin/ld doesn't support that option,
or anything like it as far as I can tell.  But that's
exactly what I need.  Is there a corresponding
parameter for the Solaris linker?

Hi Dave,

Are you using the -Wl,--whole-archive flag?

building C++ shared libs for systems w/o gcc installed

[Dave O'Hair]

I am trying to build a C++ shared lib using gcc/g++
3.2 on Solaris 8.
Everything works fine until I try to load it on a
machine that does not
have gcc installed at all, or has an older version
installed (2.95).
It complains that the library "libstdc++.so" isn't
found (indeed it is
not there).
 
So I want to link the shared lib with static linking
of the g++ runtime
libs.  I did this with the following link command:
 
g++ -shared -nodefaultlib $(OBJS)
/usr/local/lib/libstdc++.a /usr/local/lib/libsupc++.a
 
The link worked fine but when the program tries to
load (dlopen) the
shared lib, it fails with:
 
relocation error:  symbol __gxx_personality_v0:
referenced symbol not found
 
This symbol is in libstdc++.a but it doesn't get
copied into the shared lib.
Is there a way to force the linker to load everything
in libstdc++.a into the shared lib?
 
Are there any resources out there explaining how to
build C++ shared libs using
gcc/g++ for delivery to systems which don't have gcc
installed?
