II get this error (below) on a clean D& install, whenever I try to enable Sparql Views (both the dev and the 7.2.alpha3 versions). I saw something like this in connection with Filefile and Mollom, where somebody suggested this ----

Just hope this note helps someone (I killed the whole day on issue).

If you use something like this in PHP < 5.3:

 call_user_func_array(array($this, 'parent::func'), $args);

Such a script will cause segmentation fault in your webserver.
In 5.3 you should write it:

 call_user_func_array('parent::func', $args);

I just don't know how to apply this to Sprql Views. Pls help.

I haven't seen this before. There are no direct calls to call_user_func_array in SPARQL Views, so there is no where for the fix you mention to go in SV. It looks like all of the call_user_func_array calls that are in Views module use the prefered call order, so that shouldn't be where the problem is.

I'm going to leave this open to see if anyone else can confirm that it happens to them as well. Unfortunately, though, I can't reproduce this and don't readily see what is going wrong, so won't be able to offer support in the near term.

I appreciate your help. With only a passing acquaintance with coding, I have subsequently removed SPARQL Views, flushed the cache, and the error message disappeared. I am not sure where to go from here. Having this module work for me is of critical importance... Once again thanx.

Partial good news (for me , at least). I managed to enable the module without getting errors. However, I am not quite sure what did the trick - because I had tried to do all these steps without success more than a few times before. So here's what I did:

- before enabling SPARQL Views, I made sure I had RDFx installed/enabled (including the required ARC library).
- set my php.ini max executable time at 600, max input time at 600 (that had not worked for me before - so I did the next step)
-increased max execution time in my settings file \sites\default\settings.php to 900 ----- ini_set('max_execution_time', 900);
- I then installed and enabled the SPARQL Views module

Thats it. Hope this helps

Nice! great detective work, thanks for writing this up, I'll have to test it to figure out how to solve it for other people.

I am also getting the "Fatal error: Maximum function nesting level of '100' reached", even after running

Could you follow these instructions from the Views project page and see if it changes anything?

When installing Views on Drupal 7, you absolutely must have CTools of at least alpha4 and you may need to flush cache as much as twice. There are currently issues with core's cache flushing that means one cache flush isn't necessarily enough. Also, if your CTools' version is older than CTools 7.x-1.0-alpha4 things will crash a lot..

Sure, and I even flushed thrice just to be safe. But I still get the error of "100 reached" when I try to install SPARQL Views... I also tried with the latest dev version of Ctools, but with the same result. Have you got other things I can test? 8o)

did you try the sequence of things iRex posted in #3?

Also, once you have RDF UI enabled, can you check admin/reports/status and ensure that the ARC library is placed?

This may have something to do with a recent change in Entity API. Could you try one of the earlier betas of Entity, available at http://drupal.org/node/626176/release

Ok, it seems as though this problem is due to a commit in Entity API from June 14

I think you're right, nice catch! I did a fresh install with the Entity API module version 7.x-1.0-beta8 (in stead of 7.x-1.0-beta9) and the installation went through, no "Fatal error".

I am hoping to import data from other web sites, such as DBpedia, like you did in your videos "Importing and Syncing Content using RDF"(Nov.3, 2010). I think you used the Feeds View Parser module, which only exist for Drupal 6. Is the Feeds XPath Parser module the equivalent in Drupal 7, or is there a better module for importing Feeds?

Unfortunately, I don't think that there is anything that connects Views to Feeds in Drupal 7 at this point. The Feeds XPath Parser most likely enables you to use XPath on an XML file, but you wouldn't be able to use SPARQL Views in that scenario to do the import.

If no one else takes it on, I might be able to get sponsorship to connect Views and Feeds in Drupal 7 (either updating Feeds View Parser or a new approach), but that won't be for a while.

That sounds great, I will keep my fingers crossed that you get the sponsorship. It would be so cool to be able to import data from dbpedia.

If you want to bring in data from dbpedia at the moment just follow the tutorial here
http://www.ibm.com/developerworks/library/wa-datasets/

It works fine for bringing data from other datasets also, but you need to know what your looking for. You can then use views to organise that data on your site.
If you want to know more about views and what it can do check out this excellent resource
http://nodeone.se/blogg/learn-views-screencast-series-summed-up

Play around with it and see what you come up with. If you come up with something new be sure to post it on drupal.org as the more participation on here the better.

This has been fixed with #1208898: recursion error with Entity API 7.x-1.x-beta9 and another compatibility issue with entity beta9 was fixed in #1208944: Field UI no longer works with Entity API 7.x-1.x-beta9.

These changes are in the dev release. I have created an alpha4, which should show up soon.
