How to install a Ruby Gem for use in SketchUp

[Whaat]

Hey,

I downloaded Ruby-prof for profiling my code since it seems way better than the built in Ruby Profiler. However, I'm a bit stuck on how to install and use it. It comes as a GEM file and when I tried to install it from the Windows command line using the code.

gem install rub-prof

but I got some error about not being able to locate library or something.

However, even if I did manage to install it correctly what would the next step be? How do I know which files were installed? I assume that I would have to copy everything that got installed into the SketchUp plugins folder so I need to know all the files that are included in the GEM file.

Can anyone provide any guidance here?

Thanks

did you checked "If you are running Windows, make sure to install the Win32 RubyGem which includes a pre-built binary. Due to a bug in ruby-gems, you cannot install the gem to a path that contains spaces" ?

and "If you are running Windows, then install the Windows specific RubyGem which includes an already built extension."

or you can download the gem (which is a renamed .zip file), unpack, check the data.tar.gz and see the files that are inside and put them in SU dir.

you can also add to the $: the paths from Ruby install and see if it works.

use ProcMon to trace the files that it tries to open and see where to put your files.

Argghhh! I think i installed all the files correctly in the SketchUp plugins folder and I get this message when SketchUp loads:

@unknownuser said:

Error Loading File xxxxxxx.rb
127: The specified procedure could not be found. - C:/Program Files/Google/Google SketchUp 7/Plugins/ruby_prof.so

Seems to be problem with ruby-prof.so which I have placed in the Plugins folder.
If someone is able to succesfully install ruby-prof on a windows system, please let me know what you did to get it to work!

Download Ruby-prof here:

Thanks!

weird. it loads properly under Ruby command line, but it gives a DLL init error when loading under SU.
tried to rebuild with PellesC and I get the same error. I think maybe it is due BugSplat library SEH control that screw things up.

my suggestion - get another ruby profiler library

I've build it on a Mac and works just fine. I had to remove some Rails stuff from the startup but it works pretty nicely too.

Whaat, you should have in you plugins folder:

ruby_prof.so
ruby-prof.rb
ruby-prof (folder)

ruby-prof.rb just loads all the ancillary files as normal.

Can you give the actual error you get.

Hi Adam,

I posted the error above. I'm not sure what you mean.

And...I put the correct files in the plugins folder as you say.
Seems like a Windows issue. I'll have to try it on my Mac yet to see if I can get it to work.

Thanks.

When I installed yaml, I noticed there may be a case issue - I had to use:

require 'Yaml' (or require 'YAML') because require 'yaml' did not work; although the library file names were all lower case. (Windows XP SP 3)

I unfortunately no longer have it installed so I'm going from memory here...

when in Sketchup, require 'ruby_prof.so' breaks in LoadLibrary function with 'Exception C0000139 Entry Point Not Found' which is weird as it works in normal Ruby

[todd burch]

Could it be a PATH issue?

there is only loading the .so file which has dependency only for kernel32.dll, msvcrt and msvcrt-ruby18 - all loaded by SU anyway.

[AdamB]

Yep, I see the same thing here. On windows it simply wont load. I've rebuilt it locally too.

What version is the msvcrt-ruby18.dll...

...that works in normal ruby?

...that does NOT work in the SU folder?

(I got a similar error when I tried to get SU to load the 1.9.1 version ruby dll)

[tbd]

Dan: thanks, that was the problem. in Sketchup there were msvcrt-ruby18.dll version 1.8.0 and in Ruby was version 1.8.6

replacing the dll in Sketchup dir with the one from Ruby dir I was able to load

RubyProf.measure_mode = RubyProf;;CPU_TIME 
RubyProf.start
  Sketchup.active_model.entities.each {|x| x.class}
result = RubyProf.stop

File.open "d;/profile.txt", 'w' do |file|
   RubyProf;;FlatPrinter.new(result).print(file)
end

Awesome! Thanks everyone! I hope I can get it working too...

I thought so!

I always tell people, IF your using full ruby libraries with Sketchup... to make the msvcrt-ruby18.dll file in the Sketchup program folder/directory, the SAME version as your full ruby version. Otherwise your asking for Errors (such as newer library scripts calling methods that the older interpreter doesn't understand.)

I've given this advice several times over at Google Groups SU Developer's forum. Not sure if I have here. I also always say make a Sketchup/_BACKUP folder and drag the older DLL into that folder, before copying the newer 'full' DLL from the ruby/bin folder. (You never know, you may have a future need to test a script, running under the old DLL version.)

Glad I could help.

@Jim: Maybe this issue needs to be added to the Ruby Tips for Sketchup Sticky Links page?

Re: Ruby Interpreter DLL: SketchUp vs Standard

I downloaded the normal standard v 1.8.0 patch level 10 DLL (msvcrt-ruby18.dll) from:
http://www.oldapps.com/Ruby.php?old_ruby=12
and compared it against the backup that was installed with Sketchup v7.0 application.

Both standard DOS command comp and the Support Tool WinDiff report both DLL files are identical.

Given there are many fixes between 1.8.0 and 1.8.6 - and using 1.8.6 doesn't seem to cause problems - I don't know why Google are shipping quite so old a dll. In particular, I noticed a few fixes in the changelogs to Ruby related to memory leaks.

FYI Mac Sketchup uses 1.8.5

It may just be a staffing issue, they know it works with 1.8.0, but are probably reluctant to ship with 1.8.6 without massive testing. I can see management feeling such an task as being low priority.

There was also at least one person at Google, who thought wrongly (the removed quote above,) that Ruby for Sketchup had to remain at v1.8.0 because the DLL (they thought,) had been extensively modified and compiled specially for Sketchup; and that to update to 1.8.6 or any other later release would be a huge project, not likely to occur any time soon.
__Well, I think I've proved that assumption incorrect. The Ruby Interpreter DLLs are just copies of those distro'd with standard Ruby.

A good reason to use 1.8.6 with Sketchup, and I have been since a few days after I installed 7.0 (and have had no problems, so far.)

I would feel that 1.8.7 is still not ready (it just had a recent release to fix major security bugs.) But it's almost there.

I tried to get Sketchup to load 1.9.1, but it did not like the DLL. I got the 'Entry Point Not Found' error. (Not sure if it was the Ruby guys who changed things, or if it was me renaming the msvcrt-ruby191.dll to msvcrt-ruby18.dll that was the problem.)

There are those of us, who wish to run newer Ruby releases (especially the non-english users who need multibyte character support in the 1.9.x branch.) We should be able to run any Ruby release we wish.. and it would be nice if Sketchup was setup to facilitate our choice.

@adamb said:

I suspect because of the major differences in OSX and Win32 programming, that there are different people working on the two implementations.

Does OSX Leopard come with ver 1.8.5 pre-installed?
