I see that the cygwin toolset now expects wchar support, and I've heard that cygwin does indeed support wchar now, but I don't know what I need to do to get it. Simply running the cygwin installer and letting it update everything doesn't seem to do the trick. Help?
Hmmm - that's all I did and it worked fine. I did notice one thing though - it seemed to leave some older version of gcc and libraries on there. Double check that the older ones aren't being invoked with gcc -v
Ah, I had to install the gcc4 package. It installs side-by-side with the earlier gcc package, which is gcc3.
I wonder if it's a good idea for the cygwin toolset to just assume that wchar support is present, when really it's only present if the user has selected gcc4.
What is 'cygwin' toolset? In any way, the ideal solution, of course, is to use compile or run checks to detect if enough of wchar_t support is available. See regex library for examples of how is it done. - Volodya
