Build fail because sys/eventfd.h not available on Cygwin32

[nowox]

Although this question as been asked many times with different words, I still did not find a solution yet.

I was able to successfully install zeromq with this Makefile snippet:

zeromq: zeromq-4.1.3.tar.gz
    tar xvzf $<
    cd $(patsubst %.tar.gz,%, $<) && ./configure
    patch $(patsubst %.tar.gz,%, $<)/src/curve_client.cpp curve_client.patch
    patch $(patsubst %.tar.gz,%, $<)/src/curve_server.cpp curve_server.patch
    cd $(patsubst %.tar.gz,%, $<) && make
    cd $(patsubst %.tar.gz,%, $<) && make install
    rm -rf $(patsubst %.tar.gz,%, $<)

Where the patch I made was because of a warning treated as an error:

$ cat curve_client.patch
61c61
<     sodium_init();

---
>     zmq_assert (sodium_init() == 0);

The build of pyzmq-14.7.0.tar.gz fail with this:

$ python setup.py install

According to #467 I patched bundled/zeromq/src/platform.hpp

$ diff pyzmq-14.7.0/bundled/zeromq/src/platform.hpp platform.hpp.new

And this time I get this error:

When also disabling TCP_KEEP* and LIBSODIUM I eventually have linking issues:

What can I do next?

To me #113 is a different issue and #467 was not solved yet...

Update

I realized that the setup is falling back on the bundled libzmq while I was able to successfully install libzmq. When I execute:

python setup.py install --zmq=/usr/local

I have a lot of undefined references that I don't understand:

/usr/lib/gcc/x86_64-pc-cygwin/4.9.3/../../../../lib/libcygwin.a(_cygwin_crt0_common.o):_cygwin_crt0_common.cc:(.data+0x0): undefined reference to `operator new(unsigned long)'

error: command 'gcc' failed with exit status 1

Fatal: Falling back on bundled libzmq, but setup.cfg has explicitly prohibited building the libzmq extension.

Can you run ./configure in zeromq-4.1.3 and post your platform.hpp?

[nowox]

Eventually I did it...

Same here. This breaks "pip install jupyter" from cygwin.

[myloginid]

This fails on Cygwin 64 also :-(

[ptizoom]

any update on this!?
is there a replacement for envenfd under cygwin ?

Hi
Came here because 'pip3 install jupyter' failed on pyzmq installation.

I already had a working python3.6.1 with ipython3 in cygwin64 on win7
It was solved by first updating everything pending on latest cygwin64 2.8.0
download, compile and install zeromq-4.2.1.tar.gz and then just running pip3 install jupyter in the same directory:

cd /tmp
wget https://github.com/zeromq/libzmq/releases/download/v4.2.1/zeromq-4.2.1.tar.gz
cd zeromq-4.2.1
./configure
make
make install
pip3 install jupyter

The new build system for v26 prerelease runs the standard libzmq build instead of the setup, so I believe this should be resolved. Please feel free to test and open new issues against v26.
