Ocra build error

ruby-talk
1

I'm confused by this, I can't see any reason for Ocra to fail in
building a one-line script.
I've tried disabling all antiviral and active-scan related programs and
reinstalling Ocra to no avail.
The error message really doesn't give me anything to go on as far as I
can see.

Script content:
puts 'Hi'

Ocra build result:

I've just completely rebuilt the laptop (fresh install of windows) and
reinstalled Ruby with Ocra, it still gives the same error! Wtf??

This is the line causing the exception:

system("\"#{Ocra.lzmapath}\" e tmpin tmpout 2>NUL") or fail

I have no idea what it's doing.

--no-lzma works! That gets me back up and running short-term and gives
me a direction to start looking in. Thank you so much!

Aha, I've cracked it. I previously redirected the command prompt to my
most commonly used path via a registry entry called Autorun. Since
that's worked on every other computer I've used without a hitch I didn't
even think of it until I noticed Ocra's pathing code. That must have
been affecting the build process because now that I've disabled that key
value, everything works fine.
I guess the moral is: Playing with the registry may have unforeseen
consequences!

This looks as if it invokes the external compression program for LZMA,
which it probably can't find. Try to build your executable with
--disable-lzma. Note however this disables OCRA's compression
facilities and you most likely will end up with a quite large
executable.

You could also file an issue at Issues · larsch/ocra · GitHub
or join the Google group at http://groups.google.com/group/ruby-ocra .
You're more likely to get more specific help over there.

Vale,
Marvin
