Hey, one of my most favorite problems... :-)
But, I think that I have a solution. In texk/web2c/Makefile, there are
three binaries that are linked by the C++ compiler: pdftosrc, pdftex
and pdfetex. At least for linux / gcc systems, I think that adding
-nodefaultlibs -Wl,-Bstatic -lstdc++ -Wl,-Bdynamic -lgcc
fixes the problems that we have with different libstdc++ versions by
linking just this library statically.
In the Makefile, I have changed e.g.
$(kpathsea_cxx_link) pdftexdir/pdftosrc.o $(LDLIBXPDF) -lm
$(kpathsea_cxx_link) pdftexdir/pdftosrc.o $(LDLIBXPDF) -lm -nodefaultlibs -Wl,-Bstatic -lstdc++ -Wl,-Bdynamic -lgcc
and then called
rm pdftosrc; make pdftosrc; ldd pdftosrc
The same has to be done for pdftex / pdfetex.
If we find that this is a reliable way to create better binaries, I can try
to add these flags automatically (on systems that support them).
