Cygwin 1.7 contains many fundamental changes compared to older Cygwins, so maybe the failures aren't that surprising. Are any workarounds known?

I am having the same issue, does anyone know how to solve this?

thanks a lot

You can --disable-sockets , if your application does not use sockets. Otherwise, this is bug 11626 : http://trac.wxwidgets.org/ticket/11626

this is reported fixed in SVN

[kramik]

The issue is still present with 2.9.1 and 2.9.0. Haven't tried any 2.8 with cygwin. It says it was fixed in SVN but I thought that would have been released in 2.9.1.

Simply you need to configure gcc prepocessor to use winsock API with -D__USE_W32_SOCKETS define

export CPPFLAGS=-D__USE_W32_SOCKETS;
./configure --prefix=/usr/local --with-msw

I think that problem is on port of cygwin that uses /usr/include/w32api/winsock.h and ovelaps default select function on cygwin include/sys/select.h.

__USE_W32_SOCKETS define says to cygwin compiler to use winsock.h instead of default select.h and uses Windows Sockets like mingw.
