Hi,

Am trying to get rubyscript2exe to work and get the error shown below.

I’ve read the posts about this before (changing a line rubyscript2exe  
etc) but none of the answers work for me. Can someone suggest what I’m  
doing wrong? New to Ruby, by the way…

D:\rubyplay\>ruby -v  
ruby 1.8.6 (2008-08-11 patchlevel 287) [i386-mswin32]

D:\rubyplay\>helloworld.rb  
Hello World!

D:\rubyplay\>ruby rubyscript2exe-0.5.3.rb helloworld.rb  
rubyscript2exe-0.5.3.rb:621:in `replace': can't modify frozen string (TypeError) from rubyscript2exe-0.5.3.rb:621 from rubyscript2exe-0.5.3.rb:577:in`newlocation’  
from rubyscript2exe-0.5.3.rb:505:in `newlocation' from rubyscript2exe-0.5.3.rb:472:in`newlocation’  
from rubyscript2exe-0.5.3.rb:505:in `newlocation' from rubyscript2exe-0.5.3.rb:577:in`newlocation’  
from rubyscript2exe-0.5.3.rb:619

Many thanks,  
Rowantree

Look at rubyscript2exe-0.5.3.rb line 612 perhaps?

At a guess, maybe it’s doing something with $0. At some stage after  
1.8.6p114, $0 was changed from a regular string to a frozen string. If  
that’s your problem, try changing

$0.replace(“foo”)

to

$0 = “foo”

Hi,

No… 'twasn’t that unfortunately… thanks though.
