Problems with Zlib::Inflate.inflate

[Chris Malek]

I am running on windows xp and trying to inflate a string and decode
it. I am getting a

When I try to execute this script I get the following error:

deflateBase64.rb:11: uninitialized constant Zlib (NameError)


Ruby Version: 1.8.2


##########################################
require 'base64'
f = File.open("c:/temp/string.txt","r")
fout = File.open("c:/temp/decodedString","w")
fout.puts(Zlib::VERSION )
while (ln = f.gets)
inflatedString = Zlib::Inflate.inflate ln
decodeString = Base64.decode64(inflatedString)
fout.puts(decodeString)
f.close
fout.puts("closing")
fout.close


end

Anyone have any idea?

Thanks in advance.

require 'zlib' , maybe.

I tried to require zlib and I get the following error. I know it has
to be simple.



c:/ruby/lib/ruby/site_ruby/1.8/i386-msvcrt/Zlib.so: 127: The specified
procedure could not be found. - Init_Zlib (LoadError)
c:/ruby/lib/ruby/site_ruby/1.8/i386-msvcrt/Zlib.so from
c:/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:21:in
`require'

That errror was generated from this script

require 'base64'

fout = File.open("c:/temp/decodedString","w")

fout.puts(Zlib::VERSION )

while (ln = f.gets)

inflatedString = Zlib::Inflate.inflate ln
begin
decodeString = Base64.decode64(inflatedString)
fout.puts(decodeString)
rescue StandardError => err
fout.puts("an exception occured #{err}\n")
print "an exception occured #{err}\n"
rescue SyntaxError
fout.puts("o shit syntax")
ensure
f.close
fout.puts("closing")
fout.close

end

Forget my last reply. I had a case issue in the require. It turns out
zlib has to be lower case. That was my blond moment of the day.


My revised script is now throwing a different error and a google search
turns up nothing useful.

the error when running this script is:

"invalid distance too far back"
