Problem installing linkparser on Ubuntu 10

• 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:

checked program was:

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?

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

I was having the same issue where linkparser could not find ruby/intern.h or some as such. I followed the above instructions and it still did not work. I made a soft-link (ln -s) from /usr/lib/ruby/1.8/x86_64-linux/ruby/* to /usr/lib/ruby/1.8/x86_64-linux/* and when I went to compile linkparser it worked like a champ. I then tried it with 1.9.2 and it also worked on a different box.

I also was having issue with wordnet and this fix worked on that as well.

There is a bug in the gem source code which is causing the CFLAGS to be concatenated as -fPIC-I/usr/local/include instead of -fPIC -I/usr/local/include

Fix (referring to Gem version 1.1.0):

in ./ext/exconf.rb, find the following lines (should be lines 20 and 21):

$LDFLAGS << read_cmd_output( pkgconfig, '--libs-only-L', 'link-grammar' )
$CFLAGS << read_cmd_output( pkgconfig, '--cflags', 'link-grammar' ) 

and change them to:

$LDFLAGS << ' ' + `#{pkgconfig} --libs-only-L link-grammar`.chomp
$CFLAGS <<  ' ' + `#{pkgconfig} --cflags link-grammar`.chomp

this should allow you to install the gem in an rvm gemset

I've released version 1.1.2 of the gem, which includes the fix from @alexander.
