C: ctype_base.h errors with gcc 4

[neurocomp2003]

Hi all,
I was wondering if anyone has ever run into ctype_base.h errors
like:
'<anonymous enum>' is/uses anonymous type.'
error: trying to instantiate 'template<class T> void operator|(PUP::er&, T&)'

some sites that i have visited
say its an error with gcc4

GUI-mandriva
sfwr-charm++ for NchiladaNC

I haven't run into any problems with that header, though I've never explicitly included it. Can you post an example that reproduces the problem?

Try enabling concept checks to get a better diagnostic if there's an error in your code.

I'm trying to build a released software called
ChaNGa(astrophysics N-body sim) that uses charm++ as its parallel framework. Thus i haven't actuallly coded anything on my own.

The error builds pointing to the parallel language Charm++...
and technically you don't include this header it is included by other system headers. Hurkyl:"Try enabling concept checks to get a better diagnostic if there's an error in your code." How do you do this, I'm not a native linux programmer.

It's one of gcc's comand line options. I forget the exact command, but you should be able to find it in the man page, or in the online documentation.

Given that you were building in changa when the error occurred, I would first look in changa, specifically Reductions.cpp. It looks like they're trying to instantiate a function with inadequate type information. See if you can take their mpicxx command and pump up the verbosity. gcc points me to the site at which the instantiation was attempted in these situations, makes it easier to locate the problem. Try -Wall.
