Unable to install and run on Windows Server

[patrickboe]

I'm running Windows Server 2008 R2 on my development machine. WMQ Server 7.5 is installed in its default location, C:\Program Files (x86)\IBM\WebSphere MQ. When I run gem install rubywmq --platform=ruby, there is an error looking for headers in C:\Program Files[...]\include.

Following the advice on the README, I ran ruby extconf.rb --with-mqm-include="C:\Program Files (x86)\IBM\WebSphere MQ\Tools\c\include", but extconf.rb still looked for the headers in Program Files and errored out. Next, I manually edited extconf.rb to use Program Files (x86) and then ran ruby extconf.rb --with-mqm-include="C:\Program Files\IBM\WebSphere MQ\Tools\c\include" without an error.

The README then says to run nmake. When I do this, I get makefile(82) : fatal error U1000: syntax error : ')' missing in macro invocation. As an alternative, I tried just running make, which worked with no errors but a bunch of warnings. However, when I try the sample code in the README under "Verifying the build", calling require 'wmq' elicits a "cannot load such file" error.

Please let me know if I can be of any assistance in researching this issue further.

Is the MQ SDK installed and the headers files present? If so, can you attach the complete output from the gem install?

[patrickboe]

Sure - the following is from running gem install on the unedited gem. As mentioned above, I went on to edit extconf.rb to use "Program Files (x86)" but then got a syntax error on nmake.

[patrickboe]

Sorry, forgot to answer the first part of your question. I believe the SDK is installed. The directory C:\Program Files (x86)\IBM\WebSphere MQ\tools\c\include exists and contains these items:

amqsvmha.h
cmqbc.h
cmqc.h
cmqcfc.h
cmqec.h
cmqpsc.h
cmqxc.h
cmqzc.h

On Windows it looks like you have to edit extconf.rb to make it change the path of where MQ is installed.

Open a command prompt, run these commands after changing the paths to your setup:

C:\>cd C:\Ruby193\lib\ruby\gems\1.9.1\gems\rubywmq-2.0.2\ext

C:\Ruby193\lib\ruby\gems\1.9.1\gems\rubywmq-2.0.2\ext>C:\Devkit\devkitvars.bat
Adding the DevKit to PATH...

After editing the following line in extconf.rb to set the new path:

  include_path = 'C:\Program Files (x86)\IBM\WebSphere MQ\tools\c\include'

Run extconf to build a make file

C:\Ruby193\lib\ruby\gems\1.9.1\gems\rubywmq-2.0.2\ext>ruby extconf.rb
checking for cmqc.h... yes
checking for main() in -lmqm... no
Generated wmq_reason.c
Generated wmq_const_admin.rb
Generated wmq_const.rb
Generated wmq_structs.c
creating Makefile

Wipe any previous partial build

make clean

Build the shared library

make

You need the extconf step to work before running make.

Also check mkmf.log for any errors.

nmake must be from one of your other tools:

C:\Ruby193\lib\ruby\gems\1.9.1\gems\rubywmq-2.0.2\ext>nmake
'nmake' is not recognized as an internal or external command,
operable program or batch file.

If you are running bundler can you try adding the github repo directly and see if the change I just made works for you?

In Gemfile:

gem 'rubywmq', git: 'git@github.com:reidmorrison/rubywmq.git'

Then run

bundle install

The change just committed to that branch should detect the x86 path first and use it for the include files.

[patrickboe]

I had to change that to https@... from git@... to avoid a Permission denied (publickey). Then...

~> bundle install

There was a LoadError while loading rubywmq.gemspec:
cannot load such file -- rubywmq/version from
c:/Ruby193/lib/ruby/gems/1.9.1/bundler/gems/rubywmq-71e7f7ed0c0f/rubywmq.gemspec:4:in
`<main>'

Does it try to require a relative path? That's been removed in Ruby 1.9.

Not sure if it's because of the require 'rubywmq/version' - looking into alternatives now.

I've got a patch to fix the bug, but I have to run the pull request past my employer before submitting it.
