Problem installing linkparser on Ubuntu 10

Question

using rvm
using ruby 1.9.2
identical gems (and support libs) installed in OS X
link-grammar installed (via apt-get)
pkg-config working as expected.

When I run gem install linkparser I get the following error:

Building native extensions.  This could take a while...
ERROR:  Error installing linkparser:
    ERROR: Failed to build gem native extension.

/home/locallyclient/.rvm/rubies/ruby-1.9.2-p0/bin/ruby extconf.rb
checking for pkg-config... yes
checking for dictionary_create() in -llink-grammar... *** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

(plus more including cmd line options and stack trace).

mkmf.log looks like:

"gcc -o conftest -I/~/.rvm/rubies/ruby-1.9.2-p0/include/ruby-1.9.1/i686-linux -I/~/.rvm/rubies/ruby-1.9.2-p0/include/ruby-1.9.1/ruby/backward -I

cc1: error: unrecognized command line option "-fPIC-I/usr/local/include"
checked program was:
/* begin /
1: #include "ruby.h"
2: 
3: int main() {return 0;}
/ end */

( I replace the home path with '~' for easier reading)

Specifically: cc1: error: unrecognized command line option "-fPIC-I/usr/local/include"

Any ideas as to why this paramater would be mangled and where I can fix it?

and also there is space needed between "-fPIC -I/usr/local/include" — YOU
yeah, the space. I saw that. I want to know where that specific line is being generated so I could fix that :) — cbrulak
I did what S.Mark suggested on centos and it worked. I did the same thing on my ubuntu image, no joy. But the gcc versions were different, perhaps the gcc versions are part of the problem. — cbrulak

Here is few steps I tried.

Get ruby source (1.9.2 p180 for now)

$ wget ftp://ftp.ruby-lang.org//pub/ruby/1.9/ruby-1.9.2-p180.tar.gz
$ tar zxvf ruby-1.9.2-p180.tar.gz

export include path of ruby, you may write it in ~/.bashrc, to enable for other native extensions too.

$ export CPATH="`pwd`/ruby-1.9.2-p180/include":$CPATH

and looks like apt-get version of link-grammer is version 4.0 and linkparser complaining too old (>=4.7.0), so get and trunk version as they mentioned the site. v4.7.4 for now

http://www.abisource.com/projects/link-grammar/#download

note: if your ruby is in /usr/local/bin, change --prefix=/usr to --prefix=/usr/local

$ svn co http://svn.abisource.com/link-grammar/trunk link-grammar
$ cd link-grammar
$ ./autogen.sh
$ ./configure --prefix=/usr
$ make
$ sudo make install
$
$ sudo gem install linkparser
