If followed all steps for my own project with the latest newgem.
Everything works fine and it also installs the gem, but when i want
to test it i always get the error ‘no such file to load — myproject’ in
the lib/myproject.rb, where i tried

require ‘myproject.so’ and require ‘myproject’

I included the file in the Manifest with
ext/myproject/myproject.o

Did anything change in newgem since this article or why doesn’t it find the library anymore ?
I run os x leopard with ruby 1.8.6

Thanks for your help.
Regards
valley

For Windows the newgem commands through the following error
can’t convert nil into String
c:/ruby/lib/ruby/gems/1.8/gems/newgem-1.2.3/app_generators/newgem/newgem_generator.rb:169:in `join’

You need to have ENV['HOME'] setup

one way you can do is

set HOME= %USERPROFILE%

or you can go to

My Computer -> Properties -> Advanced -> Environmental Variables

and create a new User Variable

with name HOME and with value %USERPROFILE%

or best will be hoe library should fallback to

ENV['USERPROFILE'] if ENV['HOME'] is nil [Which is the case for Windows]

@Urma [via] - yeah that looks to be true; so the LOAD_PATH bit needs to be in the test file still, but can be removed from the root lib file. I've removed the line about adding the $LOAD_PATH now; thx.

@Luis Lavena [via] – yeah, I kinda like explicitly stating that you’re loading the extension as it communicates to the read where they should find the source, I think. But that’s just imo.

I’ll email you about how to pre-build mswin32 etc gems, and if extra rake tasks would be helpful.

That LOAD_PATH thing is kinda odd. Are you sure it works when installed as an actual gem? In my experience the extension target always gets moved into lib/ after Rubygems builds it.
