Basically, you need the mingw32 version of libstdc++ before you can use Cygwin b20 GCC to be able to build C++ code. Cygwin b20 comes with cygwin target libraries, and you can't simply link against those even if you specify -mno-cygwin. The libraries of interest are: - libstdc++.a << affects almost non-trivial C++ code - libiberty.a << if you want getopt etc. An easy way is to get these out of my binary distribution for mingw32 and use -L/path/to/mingw32/libraries option in addition to -mno-cygwin. Regards, Mumit - For help on using this list (especially unsubscribing), send a message to "gnu-win32-request@cygnus.com" with one line of text: "help".
