How to compile ruby-ldap on Windows.

Requirements.

  • Ruby
    • In this article, uses RubyInstaller 1.9.2-p0 or 1.8.7-p302
  • mingw
    • In this article, uses RubyInstaller’s Development Kit 3.4.5r3 (20091110)
    • This provides gcc, make, and libraries.
  • Windows SDK or Microsoft Platform SDK
    • In this article, uses Windows SDK for Windows 7 and .NET Framework 4
    • This provides lib.exe

Patch your ruby environment

Notice! It’s a stop-gap solution.
I hope it’ll be solved by newer ruby and RubyInstaller.

Why need these patch?

  • I think, struct timezone problem cause by Ruby 1.9 - Bug #2587: Forced definition of struct timezone under MinGW - Ruby Issue Tracking System
  • The force definition of gettimeofday is another ruby’s problem.
  • rbconfig.rb’s compiler option problem caused by difference of compiler version of RubyInstaller and RubyInstaller’s Development Kit.
    • RubyInstaller’s Development Kit’s gcc is 3.4.5, and this version could not understand -Wno-missing-field-initializers.
    • The ruby.exe in RubyInstaller is compiled by newer gcc.

Why need these patch?

Execute commands on Command Prompt

"C:\Program Files\Microsoft SDKs\Windows\v7.1\Bin\SetEnv.cmd"
git clone http://github.com/alexey-chebotar/ruby-ldap.git
cd ruby-ldap
ruby extconf.rb --with-wldap32
make
make install

Trouble Shooting

File truncated because make could not find ruby.exe

  • Problem

ldap-i386-mingw32.def: file not recognized: File truncated
collect2: ld returned 1 exit status
make: *** [ldap.so] Error 1
  • Solution
    For reasons not clearly understood, sometimes your ruby/bin path includes “zero sized and no exts” ruby file. (i.e. C:\Ruby192\bin\ruby)
    Therefore, make could not find true ruby file (i.e. C:\Ruby192\bin\ruby.exe)
    Please remove the fake ruby file then make will be able to find ruby.exe.
    After that, you also need to remove ldap-i386-mingw32.def or do make clean
