i have this

 jib:~/eg/ruby/rubyforge/rubyforge-0.1.1 > file bin//rubyforge
 bin//rubyforge: a ruby script text executable


 jib:~/eg/ruby/rubyforge/rubyforge-0.1.1 > cat ./gemspec.rb
 lib, version =

File::basename(File::dirname(File::expand_path(FILE))).split %r/-/,

 require 'rubygems'

 spec = Gem::Specification.new do |s|
   s.name = lib
   s.version = version
   s.platform = Gem::Platform::RUBY
   s.summary = lib

   s.files = Dir["lib/*"] + Dir["bin/*"]

   s.require_path = "lib"
   s.autorequire = lib

   s.has_rdoc = File::exist? "doc"
   s.test_suite_file = "test/#{ lib }.rb" if File::directory? "test"

   s.author = "Ara T. Howard"
   s.email = "[email protected]"
   s.homepage = "http://codeforpeople.com/lib/ruby/#{ lib }/"
 end

and this gem, apparently, does not install a ‘rubyforge’ script into the
system
bin dir. why not?

regards.

Try adding some additional spec items to your gemspec.

The following works for me:

s.bindir = “.” # yours looks to be bin
s.executables = [ “weft-qda.rb” ] # or whatever your main script is
called
s.default_executable = “weft-qda.rb”

Try adding …’

     s.bindir = "bin"
     s.executables = ["rubyforge"]

Also, I recommend dropping the autorequire as well.

thanks.

any reason why

s.executables

would not a default value of

Dir::glob(File::join("#{ bindir }", “*”)) if File::exist?(bindir)

??

i actually did try that btw. the reason it didn’t work is because the
bindir
installed to is not in my path. i have something like this setup

/usr/local/bin/ruby -> /usr/local/ruby-1.8.4/bin/ruby

/usr/local/ruby-1.8.4/*
/usr/local/ruby-1.8.3/*
/usr/local/ruby-1.8.2/*
/usr/local/ruby-1.8.1/*

etc.

so here a

gem install rubyforge-0.0.0.gem

installs into

/usr/local/bin/ruby-1.8.4/bin/rubyforge

which is not in my path.

a while back i posted this tiny patch the the top-level gem script

#
# munge rbconfig from any command line or environment kv pair
#
 kvs = []
 re = %r/^ \s* ([^=\s]+) \s* = \s* ([^\s]+) \s* $/x
 args.delete_if{|arg| (m = re.match(arg)) and (kvs <<

m.to_a.last(2))}
ENV::each{|k,v| (k =~ %r/^GEM_/) and (kvs << [k.delete(‘GEM_’),
v])}
unless kvs.empty?
require ‘rbconfig’
kvs.each{|k,v| Config::CONFIG[k] = v}
end

which allows setting of any rbconfig value on the command line.
this
allows one to do this:

gem install rubyforge-0.0.0.gem bindir=/usr/local/bin/

and other fine grained controls of any gem install. any objection to
adding
such a patch to gems? as it stands now i cannot use the gem command to
manage
anything but libs on my systems - commands simply disappear into non
PATH
directories.

i should have included to complete patched ‘gem’ script:

 Gem.manage_gems

 required_version = Gem::Version::Requirement.new(">= 1.8.0")

We need to preserve the original ARGV to use for passing gem

options

to source gems. If there is a – in the line, strip all options

after

it…its for the source building process.

 args = !ARGV.include?("--") ? ARGV.clone :

ARGV[0…ARGV.index("–")]

munge rbconfig from any command line or environment kv pair

 kvs = []
 re = %r/^ \s* ([^=\s]+) \s* = \s* ([^\s]+) \s* $/x
 args.delete_if{|arg| (m = re.match(arg)) and (kvs <<

m.to_a.last(2))}
ENV::each{|k,v| (k =~ %r/^GEM_/) and (kvs << [k.delete(‘GEM_’),
v])}
unless kvs.empty?
require ‘rbconfig’
kvs.each{|k,v| Config::CONFIG[k] = v}
end

 Gem::GemRunner.new.run(args)

not that env settings affect the install as well. so one can do

GEM_BINDIR=/usr/local/bin gem install somelib.gem
