The application compiles without complaint (see output below), but the resulting executable is much smaller than the SunOS 2.6 version.  The SunOS 2.8 executable ssod.so7 is 117556 bytes, while the SunOS 2.6 executable was 781396 bytes.  This suggests something is missing.

Ah. This is what is missing. The gcc you had under 2.6 was probably
configured to link staticly (this including everything used from
libstdc++) while the gcc you installed under 2.8 was probably
configured to link dynamicly. Add -v to your CFLAGS and gcc will dump
some extra info that should help you verify this assumption.

It's been a while since I used solaris, but ISTR that /usr/local/lib
is not searched for dynamic libs by default. That is, your solaris
install probably isn't configured to look there for libstdc++.

One fix is to set LD_LBRIARY_PATH to include /usr/local/lib :

$export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/usr/local/lib

or in csh:

>set LD_LIBRARY_PATH = ${LD_LIBRARY_PATH}:/usr/local/lib

before running the program.

An alternative is recompile the program with -static.

Finally, read 'man ld.so.1' . It likely contains something I've forgotten.
