win32utils devel - Aug 2009 - if_indextoname on Windows?

Hi all,

Windows Vista Home Premium
VC++ 9

According to MSDN, the if_indextoname() function should be included on
Vista:

http://msdn.microsoft.com/en-us/library/bb408408%28VS.85%29.aspx

However, I can''t get mkmf to see it. I tried all of these:

require ''mkmf''

if have_header(''netioapi.h'') # yes
  have_func(''if_indextoname'', ''netioapi.h'')
# no
  have_func(''if_nametoindex'', ''netioapi.h'')
# no
end

if have_header(''iphlpapi.h'') # yes
  have_func(''if_indextoname'', ''iphlpapi.h'')
# no
  have_func(''if_nametoindex'', ''iphlpapi.h'')
# no
end

have_library(''iphlpapi'') # yes
have_library(''iphlpapi'', ''if_indextoname'') #
no

What gives?

BTW, this is in an effort to get dnssd to build on Windows.

Regards,

Dan

Here is my result:

First, you must build ruby with --with-winsock2 option.

Second, WIN32_LEAN_AND_MEAN macro must not used.

C:\>irb
irb(main):001:0> require ''mkmf''
=> true
irb(main):002:0> COMMON_HEADERS.replace("#include
<winsock2.h>")
=> "#include <winsock2.h>"
irb(main):003:0> have_header(''netioapi.h'')
checking for netioapi.h... yes
=> true
irb(main):004:0> have_func(''if_indextoname'',
''netioapi.h'')
checking for if_indextoname() in netioapi.h... no
=> false
irb(main):005:0> have_func(''if_indextoname'',
''iphlpapi.h'')
checking for if_indextoname() in iphlpapi.h... no
=> false
irb(main):006:0> have_library(''iphlpapi'',
''if_indextoname'', ''netioapi.h'')
checking for if_indextoname() in iphlpapi.lib... yes
=> true
irb(main):007:0> have_func(''if_indextoname'',
''netioapi.h'')
checking for if_indextoname() in netioapi.h... yes
=> true
irb(main):008:0>
have_func(''if_nametoindex'',''netioapi.h'')
checking for if_nametoindex() in netioapi.h... yes
=> true
irb(main):009:0> have_library(''iphlpapi'',
''if_nametoindex'', ''netioapi.h'')
checking for if_nametoindex() in iphlpapi.lib... yes
=> true

Oh, Ruby itself has to be rebuilt? Oof. I''m actually curious why
winsock2.h isn''t the default. I vaguely recall this coming up at some
point before but I''ve forgotten why now.

That means modifying the source, right? Or is there a way to undef it
from extconf.rb?

Excellent, thank you.
