stdc++ and shared objects

stdc++ and shared objects

[pmills]

I've recently moved from 2.8x gcc to 2.95.1 on Solaris 2.6.  There are
some real improvements, but I'm confused about using the C++ standard
libraries.

My application uses a number of shared objects/dynamic libraries (.so
files).  Within that code I use C++ standard classes such as <fstream>,
<map>, and a bunch of others.

With the 2.8 release and libstdc++.so, this worked fine, but with the
static version of stdc++ I'm not sure what I'm supposed to do.  If I
don't link with the .a library, I get unresolved symbols at run time
for anything in my .so that's not also in my primary executable (which
*is* linked against libstdc++.a).  If I try to link my .so explicitly
with libstdc++.a, it fails with a bunch of "Text relocation remains"
errors.  I assume this is because the .a file contents were not
compiled PIC.

Are there instructions somewhere for doing this?  Thanks in advance for
and hints or pointers.
