Error when installing rbczmq in Windows - uninitialized constant GNU_CHAIN

robrenard commented 9 years ago

I couldn't install rbczmq gem on my PC.

Here follows the gem_make.out message:

Thank you.

yep me too

I don't have a Windows machine so I cant fix and test this myself, but here's a possible fix:

The problem seems to be that the GNU_CHAIN constant is undefined. It is being used here in the extconf.rb file.

I searched around and found that theGNU_CHAIN constant is some sort of a convention used for denoting shared libraries (?).

If you'll see this code here, they've initialized GNU_CHAIN in a particular way and used it below in the EXACT same manner as rbczmq uses it.

Copying the GNU_CHAIN initialization to rbczmq's extconf might solve the issue. Of course someone with a Windows machine needs to do it.

If I just change extconf.rb locally from a downloaded rbczmq gem sources, how could I properly install it from this sources? And will iruby use it and not try to download? P.S. My ruby knowledge is rather low to be sure about such things. I've only need iruby installed. Thanks

v0dro commented 9 years ago

Yes you can. Just don't change the versions. It'll automatically use the local gem.

After you make the changes run rake compile and then rake install. That should install the required changes. Btw if the fix works I'd recommend you send them a PR.

The problem im having is that the windows.h and winsock.h files aren't being found, any idea where they should be? This is when I run rake compile

@v0dro , ok, here is what I have now. I've modified extconf.rb. I've copied code declaring GNU_CHAIN:

if RUBY_PLATFORM =~ /(mswin|mingw|bccwin)/
  GNU_CHAIN = $1 == 'mingw'
  OS_WIN32 = true
  add_define "OS_WIN32"
else
  GNU_CHAIN = true
  OS_UNIX = true
  add_define 'OS_UNIX'

  add_define "HAVE_KQUEUE" if have_header("sys/event.h") and have_header("sys/queue.h")
end

After that I tried to rake compile, but it failed because there was no add_define method. I've copied it also:

def add_define(name)
  $defs.push("-D#{name}")
end

The new try of rake compile gives me stacktrace:

You're not checking for windows.h.

See this code: https://www.omniref.com/ruby/gems/MattHulse-eventmachine/0.12.10/symbols/Object::GNU_CHAIN#line=40

Also, read that whole file on omniref, I think it should have solutions to most of your problems.
