Hi,

I've read everything how to install ARC2 on RDF. Unfortunately I still have
"RDF library Not installed
ARC2 is not available. It is recommended that you install this library in order to enable support for more RDF formats and for SPARQL queries. To install, download the latest version of the library and unzip it to sites/all/modules/rdf/vendor/arc/ under the Drupal directory. For more information please refer to the handbook. "
Please help enabling ARC2 on RDF.
Thanks.

If you look in sites/all/modules/rdf/vendor/arc, do you have another arc folder?

If so, try unzipping it to sites/all/modules/rdf/vendor

I have this problem too. I placed arc2 (July 6, 2010 release) into the ~/sites/all/modules/rdf/vendor directory and renamed it "arc". This package doesn't seem to be recognized by the Drupal system. There is no second arc directory inside ~/sites/all/modules/rdf/vendor/arc.

I am still experiencing this issue. Any ideas?

Not sure what could be causing this, but try this at the top of rdf.module, outside of rdf_init():

@include_once dirname(__FILE__) . '/vendor/arc/ARC2.php';

If that doesn't work, I'm thinking there's something wrong with your ARC files.

I just figured it out. Currently, I'm using the -dev version (though I tried the alpha7 version too). After scouring the README and INSTALL files, then the pertinent issues in the issues queues, and even unrelated issues in the issues cue, a message about v7.x inspired me to take a peek at the CVS messages. There I found a CVS message reporting "add support for the libraries modules for the loading of ARC2".

I moved the 'arc' directory into the 'libraries' directory and it started working. A lot of headache could have been avoided if the INSTALL file had been updated. The current INSTALL directions included in the -dev version are faulty.

I think you were onto the problem with your suggestion, as the -dev version apparently no longer supports the 'arc' directory within 'site/all/modules/rdf/vendor'. Thank you for your assistance.

Glad you got it working. This issue is marked for 6.x-1.0-alpha6, so in the future you might want to double check that. Might have gotten the solution last month if you mentioned you were using dev ;)

Probably wasn't using the -dev version last month, but I hear ya. I should have noted the version of the thread and mentioned any deviation earlier.

@fm Thanks! After an hour of searching, your post solved my problem with the alpha8 version.

Docs added to the INSTALL.txt file.

Install arc to the libraries directory using the libraries module as per the dev readme and it works. I could not get arc2 working at vendor/arc.

INSTALL.txt needs to be updated.

I also had the same problem - arc2 not available - and fixed it by moving directory arc to the libraries directory. However, the INSTALL.txt for rdf module said to put arc in rdf/vendor/ which is still wrong.

This was version of rdf 6.x-1.0-alpha8, but I did not change the version of this issue.

I just tried to install ARC2 for OpenCalais functionality... the website where is supposed to be available is now a domain for sale...

What next?
