Compiling qtruby

DP1 · 21 January 2005 16:20

Hi -
I'm trying to compile qtruby and I'm having some issues.
I have tried both compiling from the kdebindings package AND from
the qtruby standalone package and the same error occurs:

The compile process always seems to die on an undefined reference to
some ruby functions. I'm using Fedora Core 2.

This is the last output from make:

/bin/sh ../../libtool --silent --mode=link --tag=CXX g++

quick solution:
  make -k
  make -k install
more useful solution:
could you give me the result of:
  ruby -r rbconfig -e 'c=Config::CONFIG;mc=c.keys.map{|str|str.length}.max;puts c.keys.sort.map {|dom| "#{dom.rjust mc+1} => #{c[dom]}"}.join "\n"'

The shared library 'libruby.so' is missing, so you need to build ruby with
the '--enable-shared' option. But you shouldn't usually need to use the
'qtrubyinit' command line tool anyway.

Alexander -
Thank you for the info. Make -k continued compiling but I still could
not get qtruby to work.

Thank you!
David

see the following in the other reply:
LIBRUBY => libruby.so.1.8.2
detection seems to be wrong
i *think* there are two possible
options that can have the so name
and we should probably || the
second one just in case the first
isn't set. did this in the past
but reverted as noone else had
the problem. could you revert
the revert richard? (hope i
commited really can't recall)

thanks
Alex

Hi -
Even by recompiling Ruby 1.8.2 with --enable-shared, I still have the
same problem.

Thanks -
David
