Hello -- I'm trying to get access to rb_ary_replace, which I see defined and used in array.c but can't use in my own C code. I get: ruby: error in loading shared libraries: /usr/local/lib/ruby/1.6/i586-linux/Test.so: undefined symbol: rb_ary_replace when I try to use it. Is there (a) a reason for this method not being available, or (b) a way to use it from C that I'm not thinking of? (That would include any way that works :-) Thanks -- David -- David Alan Black home: dblack / candle.superlink.net work: blackdav / shu.edu Web: http://pirate.shu.edu/~blackdav
