Re: _ctype_ undefined?


This was answered from Mumit somtimes ago: If you use "-mno-cygwin" you
need the mingw32-librarys "libstdc++" and (if you use it) "libg++"
+"libiberty". Get the whole Mingw32-package from Mumits ftp-site, make a
directory "(your CYGWIN-dir)/lib/mingw32" and put (only) the
Mingw32-libs in it.
You must call gcc now with "-mno-cygwin" and 
"-L (your CYGWIN-dir)/lib/mingw32" so that this libs would be found.
Or (what i've done) change your spec-file, so that the linker found this
libs if you use "-mno-cygwin":

(...)
*link:
(...) %{mno-cygwin:-L /(your CYGWIN-dir)/lib/mingw32-lib}

I hope that this will help you.

But there is still the question: Why is there a switch "-mno-cygwin"
and the Mingw32-includes also, but not the libs? Is there the plan to
add them in the future to the CYGWIN-package?
