Unable to compile on Windows 7

[bandlor]

Dear all,

I struggled whole day with this issue and failed to compile this on my Windows 7 box.
My setup is Ruby 1.9.3p0 (from Ruby Installer) or Ruby 1.9.3p194 (Bitnami Rubystack)
on Windows 7 Enterprise SP1, Ruby DevKit 4.5.2 (2011-12-29) and MS Visual Studio 9.0
(the only one with lib.exe working for me from different MS SKD Devel sets).

I followed https://github.com/alexey-chebotar/ruby-ldap/wiki/How-to-compile-ruby-ldap-on-Windows for compile instruction and modified the header files and replaced few remaining STR2CSTR with StringValueCStr. With other issues (MS Libs, searching for lib.exe and other) I spent all day on this and ended with:

C:\Data\Temp\ruby-ldap-0.9.8>make
generating ldap-i386-mingw32.def
compiling conn.c

conn.c: In function 'rb_ldap_parse_result':

make: *** [conn.o] Error 1

I gave up here (I am allergic to C), desperate and exhausted, searching for other options and found the pre-compiled version from Nazy (https://github.com/downloads/nazy/ruby-ldap/ruby-ldap-0.9.11-x86-mingw32.gem) - many thanks for that.

I thank you guys for the effort you made the and I hope I will still be able to use this lib in the future. I was using pre-compiled 0.9.8 with my Rails2 project, I hope this one will work well with Rails3.

Let me know if I can help with any testing etc.

This problem is caused by 2 matters.

First, gcc could not find wldap32.lib when linking time.

• This is not true solution, but if you copy wldap32.lib to ruby-ldap directory, gcc can find and use it.
• wldap32.lib 's full path is C:\Program Files\Microsoft SDKs\Windows\v7.1\Lib\wldap32.lib in default.
• To solve it essentially, need to improve extconf,rb

Second, ruby-ldap using function which not implemented in wldap32.

• So that, gcc can't resolve following function.
  • ldap_initialize
  • ldap_explode_rdn
• To solve it, implement stub function of them or just raise the "not implemented" exception.

Any idea what to do to fix this?
