Re: libstdc++ can not working correct yet...

[Keen Wayne A Contr AFRL/MNGG]

The code in question compiles and runs successfully using:

g++ -o striner striner.cpp.cpp

where striner.cpp is the sourcefile I copied your code into.

I am testing on a pc running Cygwin and gcc-3.1.1.  If you use:

gcc -o striner striner.cpp

It generates a lot of errors, in my case something like:

This is expected, as the g++ command grabs more C++ specific items to link.
Hope that helps.

Hi,
This is not a libstdc++ issue, its a generic GCC question.
I CC'd this to the gcc-help mailing list. Let's continue
the discussion there, instead of bothering this mailing
list, ok?

You didn't send the actual error messages, so I can't
really help you ;-). Are you sure you are compiling with g++
and not with gcc?

And as for gcc installations instructions, you can find them
on them website gcc.gnu.org
