Error during installation

[henry74]

Ubuntu 7.04 ruby 1.8.5 (2006-08-25) [i486-linux]

After running the last command in these instructions:

  $ tar -xvzf link-grammar-4.2.4.tar.gz
  $ cd link-grammar-4.2.4
  $ patch -p1 < ../link-grammar-4.2.4.patch
  $ ./configure; make; sudo make install
  $ cd ..
  $ sudo ./install.rb  <===this one

I receive the following error:

/usr/bin/ruby: symbol lookup error: ext/linkparser_ext.so: 
    undefined symbol: linkage_constituent_tree

I've received this error with both the pre-packaged download(Ruby-LinkParser?-20070611.tar.gz) as well as the latest source code checked out from  svn://deveiate.org/Ruby-LinkParser2/trunk

I'll try it out on my own Ubuntu box. Thanks for the report.

It worked fine for me on a (pretty much) brand new Ubuntu 7.04 box:

That error happens when you build against an unpatched version of the link-grammar library. Did you perhaps you built against a version of liblink-grammar that was already installed? The version I'm using comes from the Abiword project -- do you perhaps have that installed? If you do ldconfig -p | grep link-grammar does it list one in /usr/lib first?

This should now be a non-issue, as the canonical library no longer needs a patch for this function.
