What am I missing?
19:37:40 fred@appel:~$ locate libstdc++.a | grep x-
/home/cygwin/cygwin-1.3.3/linux-x-cygwin/usr/lib/gcc-lib/i686-pc-cygwin/2.95.3-5/libstdc++.a
/home/cygwin/cygwin-1.3.3/linux-x-cygwin/usr/lib/libstdc++.a.2.10.0

/home/cygwin/cygwin-1.3.6/linux-x-cygwin/usr/lib/libstdc++.a.2.10.0
This x-compiles fine here
#include iostream
#include string
int
main ()
{
string s = Hello world;
cout s endl;
return 0;
}
Greetings,
Jan.

I have no idea how to do that. I don't know either -- this is why I'm asking for help. I think that was clear. What I'm trying to say is that it may not be possible to use functions from libstdc++.a. In gcc 3.x, this will include things like new() and delete(). cgf

(libsupc++.a contains the eh and new/delete stuff that is currently in libgcc.a for mingw). Locale class support is missing (as it is with cygwin/newlib), but C-locale works for me. Wide char support is missing, because of deficiencies in C-runtime. If you want wide char with -mno-cygwin, you'll need an auxiliary library -- like mingw's [incomplete] libisocext.a -- to supply C wide char support. Iostreams work for char. In 3.1 -mno-cygwin needs the mingw32/bits headers. Also, there may be differences in the way the C_runtime functions are promoted into namespace std. Hmm. I haven't been able to build libstdc++ v3 for cygwin for a while. Maybe it's just a cross build error. cgf
