PDF::Writer Boggles

[Brian McCallister]

Neither Austin nor myself has been able to diagnose this one.
PDF::Writer is bombing on me in a new and confusing way. Austin
suggested I post here...

When I try to generate the manual:

Howeverm it gets even better -- that stack trace is from yesterday
when I originally posted the problem to Austin. Attempting again
today I get a different stack trace!

Your ruby is hosed, or you aren't actually running under the version
you compiled. I had a problem before where even though 'which ruby'
showed /usr/local/bin/ruby, when I executed ruby it was still using
the version in /usr/bin.

What options did you give ./configure when you built ruby? Did you
build readline first?

Here is the output from my machine:

legolas:~/Download/src/jruby jason$ uname -mpsrv
Darwin 8.1.0 Darwin Kernel Version 8.1.0: Tue May 10 18:16:08 PDT 2005; roo=
t:xnu

legolas:~/Download/src/jruby jason$ ruby -v
ruby 1.8.2 (2004-12-25) [powerpc-darwin8.1.0]

legolas:~/Download/src/jruby jason$ which ruby
/usr/local/bin/ruby

legolas:~/Download/src/jruby jason$ /usr/bin/ruby -v
ruby 1.8.2 (2004-12-25) [powerpc-darwin8.0]


Notice my 'ruby -v' shows [powerpc-darwin8.1.0] whereas on your
machine shows [powerpc-darwin8.0.0].

Better try building ruby again. Also make sure after you build ruby
that you rebuild rubygems. I first had to close the active terminal
window and open a new one for this to build correctly.


Hope that helps,

Jason

Rebuilt, letting darwinports handle the readline nastiness this time,
and its working fine.

Good catch, thanks!

Good catch, thanks!

Yes. Thanks! I had a feeling it was a build issue, but it didn't make
sense to me to be able to call it one way or another.
