The webpage http://trac.sagemath.org/wiki/Cygwin64Port indicates that
sage can now be built under cygwin64 almost out of the box. So, I tried,
but I failed...
Here are the problems I encountered, maybe someone with better computer
skills can see what is going on. My sage version is sage 6.4beta5 with
#17365 pulled. Very recent cygwin64
- First, pyzmq did not compile, because of undefined references in
libzmq.a. It seems that the flag -no-undefined was not passed to ld
while building libzmq.a (despite #17333). I hacked the makefile to make
sure that the flag was passed when compiling zeromq, this solved the issue.
- Then, while compiling sage proper, I get the following error
gcc -I/usr/include/ncurses -fno-strict-aliasing -g -O2 -DNDEBUG -g
-fwrapv -O3 -Wall -I/home/Sebastien/sage/local/include

Looks like a problem with mpir, or a linking problem... I can give more
details or log files if needed.
