Can't build on Windows (checking for htons in arpa/inet.h... no)

[cstrahan]

Here's the output when I try to install this gem:

Does anyone know how I can resolve this? Shouldn't it be looking in winsock.h, as opposed to arpa/inet.h?

Thanks,

You'll probably need to fix extconf.rb to look for the correct headers then. I don't have windows so I can't help :(

Hello, this can be cross-compiled and tested using rake-compiler: https://github.com/luislavena/rake-compiler

It needs the proper header exclusion/inclusion for Windows, which can be sorted out without the need of a Windows machine, just time :(

Hello

I encounter the same problem. On Windows, htons and ntohs are in the winsock2.h include file. The following patch should solve the problem :

--- extconf_.rb 2011-04-09 23:58:11.489221900 +0200

+++ extconf.rb 2011-04-09 22:38:54.000000000 +0200

These functions live in netioapi.h on Windows, not net/if.h. The MSDN

I will be pleased to test the new gem and help make it work on Windows...

Asked related question on stack overflow. There seems to be a fork which might address this issue here: https://github.com/Donavan/dnssd But, I'm not sure how to use it. http://stackoverflow.com/questions/20039202/cant-find-gem-specification-to-use-forked-gem
