Eventmachine talk - Dec 2007 - Problems trying to install .10 on windows.

Hello all.

I am trying to install the latest version on windows and I get the
following error.

D:\inbox\eventmachine-0.10.0>gem install eventmachine-0.10.0.gem
Building native extensions.  This could take a while...

Running the setup.rb manually also gives the same error.

Have you successfully built  EM on Windows before? If not, try the
precompiled Win32 gem (if it''s not available for 0.10 yet, just use a
back
version. Unless you need the latest features, that should work fine.

If you have built successfully on Windows before, then perhaps there''s
a
regression in 0.10 that no one caught. Please let me know.

No I haven''t.  I thought that the pure ruby version would not need the
compiled binary.  I will use an older version.

There should probably be a separate gem for installing just the pure
ruby version.  That would eliminate that problem.

The pure Ruby version does NOT need the compiled binary. If you installed
the gem and got a compile failure, you probably DID successfully install the
code, and you probably DO have  the pure Ruby version ready for use.

Try it.

I''ve been trying to avoid having separate install gems for pure Ruby
and
C++, but we''ll do that if we have to. I''m already resigned to
needing a
separate gem for the JRuby version, which will need to install a jar file.

Is there any way to make intelligent decisions on what gets
built/installed when a gem is installed?

Or to catch compilation errors and return a message about "Extension
compilation failed, continuing on with installation of the pure ruby
EventMachine."

Because when there are compilation failures while installing a gem,
that is what people focus on.  It gives the impression that the whole
thing failed.

I''d really love to do that but I''m not knowledgeable enough
about rubygem
config to do it.

I don''t think I''m missing something trivial, but I could be.
Help, anyone?

I guess you''re right. I gave up trying to make a gem that would be
smart
enough to install the JRuby EM jar file rather than run the compiler.

I''ve seen something similar in the postgres libraries, where there are
different gems with different naming conventions for pure-ruby and
libpg-based libraries.

It''s a drag because we will need to teach EM users about the platform
differences just to get the install done, before they''ve had a chance
to
just try the product out.

You might could just output a note ''compilation failure
doesn''t mean anything''
That much is possible, I believe.

In my case it might actually mean something. The gem is in the proper
place but I don''t think it''s still properly installed.

This snippet gives an error.

$eventmachine_library = :pure_ruby
require ''eventmachine''

module EchoServer
   def receive_data data
    send_data ">>>you sent: #{data}"
    close_connection if data =~ /quit/i
   end
end

EventMachine::run {
  EventMachine::open_datagram_socket "127.0.0.100", 1111, EchoServer
}


Gives the following error

./eventmachine.rb:13: uninitialized constant EventMachine (NameError)
	from d:/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in
`gem_original_require''
	from d:/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in
`require''
	from D:/Source/ruby/engine/test/eventmachine.rb:3
Process ruby exited with code 1


As you can see somehow the file was not included properly.

Try saying require ''rubygems'' first.

A separate gem for the pure Ruby version would be really handy.

I tried that. It still doesn''t seem to work. As I said I think the
install went wrong somehow. Gem search evenmachine shows no results so
obviously some index internally hasn''t been updated.

Maybe something is wrong with my gems. When I attempt to run gem
generate_index I get the following error

gem generate_index
Generating index for 0 gems in .

Loaded all gems
Generating master indexes (this may take a while)
ERROR:  While executing gem ... (Errno::EACCES)
    Permission denied -
C:/DOCUME~1/tim/LOCALS~1/Temp/gem_generate_index_4236/quick or ./quick

What an odd error message. How could I not have permissions to temp in
my own profile?

Tim, are you able to use an earlier EM version that is precompiled for Win32
(I think 0.8.0 is available)? At least that way you can get started with
your application.

I think that as a general rule, the deployment model for Windows has to be
with precompiled gems, because the build-chain problem is such a bear on
Windows (requiring VC6; requiring a compiler in the first place; etc, etc).

Try re-running it?  I can send you a copy of the latest if you''d like.
