I have no idea why this happened and no idea how to install it properly.
I'm just following instructions from a book. If you have the time,
please elaborate on your answers.

Thanks guys!!!

This might provide some information.

Are you using Ruby 1.9.2 provided from RubyInstaller?

If so, then you should have installed DevKit, available in the same page
and with installation instructions here:

If you followed all the instructions, there is a high chance the problem
you're having is covered in RubyInstaller's troubleshooting page:

Please check all the other elements from above wiki page for other
issues.

Or maybe I should just download the latest Ruby version and the latest
Devkit version? I haven't tried that yet.

Hello!

Dunno why you keep attempting to use 3.4.5 version.

In Development Kit · oneclick/rubyinstaller Wiki · GitHub , it
says:

"For RubyInstaller’s previous to 1.9.2-p0 you may feel more comfortable
using the DevKit-3.4.5-CCYYMMDD-sfx.exe as the earlier RubyInstallers
were built using MSys/MinGW v3.4.5. "

My Ruby is 1.9.2-p0 and that is why I chose DevKit 3.4.5

While the gist is particular to my system and installing rdiscount, I
suspect that your operating_system.rb doesn't look like what's shown.

I found operating_system.rb at
C:\Ruby192\lib\ruby\1.9.1\rubygems\defaults , opened it with SciTE:

# override 'gem install' to enable RubyInstaller DevKit usage
Gem.pre_install do |i|
  unless ENV['PATH'].include?('C:\\DevKit\\mingw\\bin') then
    puts 'Temporarily enhancing PATH to include DevKit...'
    ENV['PATH'] = 'C:\\DevKit\\bin;C:\\DevKit\\mingw\\bin;' +
ENV['PATH']
  end
end

I guess you're right, Jon? It doesn't look like yours.
Would you mind explaining its significance?

Show the results for Luis' question by changing to your C:\DevKit
directory and running "ruby dk.rb install"

The result is:
C:\DevKit>ruby dk.rb install
[INFO] RubyGems override already in place for C:/Ruby192, skipping.
[WARN] DevKit helper library already exists for C:/Ruby192, skipping.

I guess that's because I've already installed dk.rb?
Or should I uninstall Ruby and DevKit and starch from scratch?

Thank you!

Luis, maybe I misunderstood

"For RubyInstaller’s previous to 1.9.2-p0 you may feel more comfortable
using the DevKit-3.4.5-CCYYMMDD-sfx.exe as the earlier RubyInstallers
were built using MSys/MinGW v3.4.5. "

'previous to 1.9.2-p0 ...' means versions BEFORE 1.9.2-p0 ??

Sorry =)

Which means that you should use a DevKit *later than* 3.4.5 for Ruby
versions >= 1.9.0!

The 3.4.5 DevKit is for Ruby at version 1.8.x. :slight_smile:

That means Ruby version < 1.9.2-p0

Ruby 1.9.2-p0 or greater should use DevKit 4.5.x

That means:

version >= 1.9.2-p0

how do I

There's no 'uninstall'.

Just remove DevKit folder, unpack the new version, proceed with the
DevKit instructions and when doing "ruby dk.rb install" use --force:

ruby dk.rb install --force

Which will "force" the installation of this newer DevKit to replace the
existing configuration.

Just in case this is helpful to anyone else, I came across this post and
had the exact same problem only I was already using version 4.5.2 of the
devkit so this post didn't really help me much.

I felt like I had tried everything, and I was mainly executing out of
PowerShell, so as a hail mary I switched over to command and low and
behold right before execution ended in the error reported in this post I
got a Windows error popup saying:
as.exe - Entry Point Not Found

The procedure entry point libiconv_set_relocation_prefix could not be
located in the dynamic link library libiconv-2.dll

I started searching around for that error and found an obscure post on
the Harbor Google Group talking about problems with libiconv-2.dll
(https://groups.google.com/d/msg/harbour-devel/sM7uXpWaftk/Y7mc3OKoEmsJ).
In the very last post one of the forum helpers told the person to check
for other copies of the libiconv-2.dll file, so I decided to follow
that.

After searching my entire disk, I found that I had 4 libiconv-2.dll
files:
1 in C:\DevKit\mingw\bin
1 in C:\DevKit\mingw\libexec\gcc\mingw32\4.5.2
1 in C:\Windows\SysWOW64
1 in C:\Program Files (x86)\Git\bin

At that point I started with the Git DLL and worked my way back to the
Windows one and renamed them to .bak. Sure enough after renaming the
libiconv-2.dll in C:\Windows\SysWOW64 I was able to compile rdiscount
without a hitch.

I don't really see this as much of a permanent solution as I am pretty
sure that, that dll is needed by Windows to run 32-bit programs on
64-bit platforms, but I was able to use renaming it as a workaround so
that I could install the few gems that I really cared about before
renaming it back the way it was so I didn't end up with Windows problems
down the line.

Anyway, hopefully this helps someone else out there! It took a long time
to track down.

Ah, it's the same as what was output to your console. I was hoping it would have more information.

Where is Ruby installed on your system? Does the config.yml file generated by the DevKit setup match your installed Ruby?

Do you have the operating_system.rb file as mentioned in step 4? Does it look right? If you're not sure, you could try posting that and your devkit.rb file here so we can review them. I don't know what it's supposed to look like, but I can at least see the source and make an educated guess. :slight_smile:

Hi Phillip. I already installed Devkit. The problem right now is in
Step 5 (Test Installation) from the following web page:

I'm supposed to install rdiscount to 'Confirm your Ruby environment is
correctly using the DevKit'. Apparently it's not correctly using the
DevKit.

I downloaded DevKit-3.4.5-20100819-1535-sfx.exe and followed the
instructions on

I don't have any idea what's wrong. I'm a beginner.

Thanks a lot!

Where is Ruby installed on your system?

Ruby is installed in the default folder: C:\Ruby192

Devkit is installed in 'C:\DevKit' (I merely followed the example from
the website with Devkit instructions.)

Does the config.yml file
generated by the DevKit setup match your installed Ruby?

I'm not sure what you mean by that but I tried opening the config.yml
file found in 'C:\DevKit' with SciTE and this is what it says:

# This configuration file contains the absolute path locations of all
# installed Rubies to be enhanced to work with the DevKit. This config
# file is generated by the 'ruby dk.rb init' step and may be modified
# before running the 'ruby dk.rb install' step. To include any installed
# Rubies that were not automagically discovered, simply add a line below
# the triple hyphens with the absolute path to the Ruby root directory.

···

#
# Example:
#
# ---
# - C:/ruby19trunk
# - C:/ruby192dev
#
---
- C:/Ruby192

Do you have the operating_system.rb file as mentioned in step 4? Does it
look right?

I can't find the operating_system.rb file.

From Step 4: "finally, ruby dk.rb install to DevKit enhance your
installed Rubies. This step installs (or updates) an operating_system.rb
file into the relevant directory needed to implement a RubyGems
pre_install hook..."

I don't even know what the 'relevant directory' is.
If it's the C:\DevKit directory, operating_system.rb is NOT there.

If you're not sure, you could try posting that and your
devkit.rb file here so we can review them.

In C:\Ruby192\lib\ruby\site_ruby , there is a devkit.rb , opened it with
SciTE, contents are:

# enable RubyInstaller DevKit usage as a vendorable helper library
unless ENV['PATH'].include?('C:\\DevKit\\mingw\\bin') then
  puts 'Temporarily enhancing PATH to include DevKit...'
  ENV['PATH'] = 'C:\\DevKit\\bin;C:\\DevKit\\mingw\\bin;' + ENV['PATH']
end

Thanks so much for your patience guys =)

Where is Ruby installed on your system?

Ruby is installed in the default folder: C:\Ruby192

Devkit is installed in 'C:\DevKit' (I merely followed the example from
the website with Devkit instructions.)

You didn't read my comment.

You have the *wrong* version of DevKit.

You *need* DevKit 4.5.2 which is listed in the downloads page:

Dunno why you keep attempting to use 3.4.5 version.

Does the config.yml file
generated by the DevKit setup match your installed Ruby?

I'm not sure what you mean by that but I tried opening the config.yml
file found in 'C:\DevKit' with SciTE and this is what it says:

# This configuration file contains the absolute path locations of all
# installed Rubies to be enhanced to work with the DevKit. This config
# file is generated by the 'ruby dk.rb init' step and may be modified
# before running the 'ruby dk.rb install' step. To include any installed
# Rubies that were not automagically discovered, simply add a line below
# the triple hyphens with the absolute path to the Ruby root directory.
#
# Example:
#
# ---
# - C:/ruby19trunk
# - C:/ruby192dev
#
---
- C:/Ruby192

That is correct, that is what it should say.

What is the output of "ruby dk.rb install" ?

From what it seems the DevKit is not getting installed inside your Ruby
installation.

installation.

Take a look at RubyInstaller 1.9 rdiscount installation · GitHub and the two helper files
paying attention to the comment (file location on my system) line at the
top of both.

While the gist is particular to my system and installing rdiscount, I
suspect that your operating_system.rb doesn't look like what's shown.

The two places to look for operating_system.rb on your system are

C:\Ruby192\lib\ruby\site_ruby\1.9.1\rubygems\defaults
C:\Ruby192\lib\ruby\1.9.1\rubygems\defaults

Show the results for Luis' question by changing to your C:\DevKit
directory and running "ruby dk.rb install" Also show us your
operating_system.rb once you've found it.

The fix may be as simple as "ruby dk.rb install --force" but reply with
answers before running that command.
