egcs not automatically linking against libstdc++

egcs not automatically linking against libstdc++

[Glenn Gebhart]

Heylo all...

A few days ago something (I have no idea what) broke on our system,
resulting in egcs ceasing to automatically link against libstc++. Attempts
to compile now die with complaints about unresolved references to symbols
like "cerr" and "cout". I have reinstalled egcs 1.1.1, and done a fresh
install of the June 8th egcs snapshot, but even after reinstalling in /usr
things are still broken. For reference we are running Solaris 2.6. If
anyone could lend a hand it would be most appreciated.

Did a sysadmin decide to rewrite your LD_LIBRARY_PATH for you without
telling anyone? I've had this happen to me before. Is libstdc++ the
only library that doesn't link or is that just the first one it gets
to thus failing before other missing symbols are discovered? The only
other think I'd consider is whether you did a "configure
--enable-shared" when you rebuilt so that your shared library support
got created.

	later & good luck,

No, I already considered that. I neglected to mention that if you
explicitly link against libstdc++ via "-lstdc++" the problem goes away.

Are you really running the `g++' compiler driver, or just `gcc'?  The
latter won't automatically link with libstdc++, even though it will
compile C++ code.

It would help a lot if you prepare a complete bug report. How did you
install the compiler? What program are you trying to compile? How do
you invoke the compile? Please do that with -v. What exact error
message does it produce?

Thanks,
Martin

I was running gcc. Running g++ seems to have done the trick. Thank you
muchly.
