Cygwin 1.7.1 fails to compile wxWidgets 2.8.10 and 2.9.0

Do you have a typical platform dependent issue you're battling with ? Ask it here. Make sure you mention your platform, compiler, and wxWidgets version.

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

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

still can't compile in cygwin

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.

Conpiled with:

- wxWidgets-2.8.10
- CYGWIN_NT-5.1 TR374 1.7.8(0.236/5/3) 2011-03-01 09:36 i686 Cygwin
