More problems with QuantLib-Ruby

[Liguo Song]

After upgrading to ruby-1.8.0, I begin to experience a new problem.

In ruby-1.6.*, the host-os is linux, which is what the setup.rb expects. But in
ruby-1.8.0, the host-os is called linux-gnu, which really ruins the day for the
setup.rb.

I can modify the source with the RPM package. But, this might cause problem for
the future release. Any patch from the ruby gurus on this list?

Thanks.

Hmm. Maybe a Red Hat thing---it's still 'linux' in ruby 1.8.0 on  
Debian.

It's a small fix anyway---wherever it says

when 'linux'

change it to

when 'linux','linux-gnu'

I already committed it to cvs.

Thanks,

I encountered another problem with QuantLib-Ruby with ruby-1.8.

In the setup.rb, there is
    Config::CONFIG["rubylibdir"].gsub("^#{oldPrefix}","")
This line of code will give the following warning during the
installation process:
    warning: string pattern instead of regexp; metacharacters no
    longer effective

The effect of this problem is that the oldPrefix is not cleared as
intended. It works OK with ruby-1.6 but not ruby-1.8. Some changes in
ruby must caused this problem. Can any experts in ruby offer any
solution for this?

Thanks.

It just became a fashion for me to reply myself. A bad habit. :(

This turn out to be another bug report.

In ruby-1.8 and later (if there is), string and regex pattern cannot
mix together any more in the gsub(). So, please replace the following
two lines in setup.rb:
        archDir    = Prefix + \
                     Config::CONFIG["archdir"].gsub("^#{oldPrefix}","")
        libDir     = Prefix + \
                     Config::CONFIG["rubylibdir"].gsub("^#{oldPrefix}","")
with the following:
        archDir    = Prefix + \
                     Config::CONFIG["archdir"].gsub(/^#{oldPrefix}/,"")
        libDir     = Prefix + \
                     Config::CONFIG["rubylibdir"].gsub(/^#{oldPrefix}/,"")

The latter format is support by both ruby 1.6 and 1.8. I hope this would
solve the last problem with QuantLib-Ruby.

Thanks for your guys' patience. :)

Ok, I fixed this for 0.3.4

Tee-hee. I fixed this as well.

Hmm. The file didn't get included in the tarball. It it fixed for  
0.3.4. As for 0.3.3, you can work around it by taking scheduler.i from  
any of the other modules (Python, Ruby, MzScheme) and copying it  
together with the other .i files in QuantLib-Guile.

Not a quick one---I'll have to code it into setup.scm.
I'll see what I can do.
