Help testing Gem em-udns under Mac OSX 32/64 bits

luislavena · August 19, 2011, 8:59pm

Hi, I’ve made a commit in Gem em-udns to allow compiling udns C
library under MacOSX 32 and 64 bits, but I need testing as I’m not a
Mac user.

Could somebody with Mac 32/64 bits install the Ruby Gem em-udns (last
version is 0.2.5) and tell me the success of the installation?

Thanks a lot.

Integrate udns sources into em-udns

C udns Gem

For now em-udns relies on [udns](http://www.corpit.ru/mjt/udns.html) C library i…nstalled in the system (see `have_library("udns")` in ext/extconf.rb and `#include <udns.h>` in ext/em-udns.c). However udns is not mantained in Linux distributions. Last version in Debian/Ubuntu is 0.0.9 while current udns version is 0.1.0 (fixing some bugs). Also, udns tarball doesn't include "make install", but just "make", and it generates a static linudns.a and not a dynamic libdudsn.so. The author of udns said me this in udns maillist: > You can try running `make sharedlib' in the udns source directory --this will produce a series of .lo files, just like it produces a bunch of .o files for static library. You grab these .lo files and produce a static library from them -- libudns.a, like this:<pre> > rm -f libudns.a > ar r libudns.a *.lo > </pre> > This is not perfect, but will work for your case. Regular static library will not - because you're producing shared object from it, and regular static library is meant to be used to produce a simple executable. > Another alternative is to re-implement the makefile using the same build system as uses - this is trivial, you just need to take a list of files from udns Makefile. So we need udns sources to be included within the em-udns gem, so `gem install em-udns` would compile udns, and em-udns would compiled against it. The first solution given above (using `make sharedlib` and `ar r libudns.a *.lo`) does work, but I don't know how to integrate it within a gem. Or maybe it's better just to modify the Makefile of udns and integrate it in some way.

Build looks okay. This is on 64 bit snow leopard. Sample from github
works too:

SOLAR:RandomRubyCode chriswhite$ ruby em-udns-test.rb
result => [“74.125.224.84”, “74.125.224.81”, “74.125.224.82”,
“74.125.224.80”, “74.125.224.83”]

Best Regards,
