Compile Fails On Missing libev But Is Installed

[xevix]

I have tried with libev 4.0.4 installed in /usr and in /usr/local but neither seem to work, i keep getting this:

$ python3 ./waf build

I compiled/installed myself, since my version of Kubuntu only has libev3 and zerogw seems to require libev4.

I guess the real question is which version of libev should I be using? I just compiled libev-examples (https://github.com/coolaj86/libev-examples) using libev4 and had no problems, I checked ldd and we're good.

$ ldd unix-echo-client 
        linux-gate.so.1 =>  (0x00a2e000)
        libev.so.4 => /usr/lib/libev.so.4 (0x00f61000)
        libc.so.6 => /lib/i386-linux-gnu/libc.so.6 (0x00851000)
        libm.so.6 => /lib/i386-linux-gnu/libm.so.6 (0x00c14000)
        /lib/ld-linux.so.2 (0x00e3e000)

You need to recompile libwebsite, it has been compiled against old version of libev.

Frankly I need to add a check in libwebsite, because it is very frequent mistake (on ubuntu :) )

Yep, that did the trick, thanks!
