Category: genxref Group: current cvs Status: Open Resolution: None Priority: 5 Private: No Submitted By: Yannick Roberts (yor1001) Assigned to: Andre-Littoz (ajlittoz) Summary: No identifiers Visible or selected Initial Comment: LXR version 0.10.2 Database Mysql OS Ubuntu 10.04 Server Edition Plain Files I have spent hours trying to figure out why identifiers were not hyperlinked in the web interface, or the identifier search wasn't returning any results... The reason was ctags, or gnu ctags for that matter, which options seems to be different from exuberant's ctag. A patch to ensure exuberant ctag is used would save many alot of trouble. ---------------------------------------------------------------------- >Comment By: Yannick Roberts (yor1001) Date: 2012-02-22 14:56 Message: Found a reason... Line 137 in genxref seems to change $1 before it is checked $version =~ /(\d+)/; I moved line 137 to line 142 and it aborted just fine. ---------------------------------------------------------------------- Comment By: Yannick Roberts (yor1001) Date: 2012-02-22 14:40 Message: Here is the genxref output for gnu ctag Checking Perl version ... 5.10.1 OK 'ectagsbin' not equal to `which ctags` If this is a non-system copy, ignore this warning Checking ctags version ... OK Checking glimpse version ... 4.18.5 Checking glimpseindex version ... 4.18.5 Parameter 'swishbin' not defined - trying to find swish-e 'swishbin' temporarily adjusted to /usr/bin/swish-e Manually update lxr.conf for permanent setting Checking swishe version ... 2.4.7 Here is exuberants ctags Checking Perl version ... 5.10.1 OK Checking ctags version ... 5.8 OK Checking glimpse version ... 4.18.5 Checking glimpseindex version ... 4.18.5 Parameter 'swishbin' not defined - trying to find swish-e 'swishbin' temporarily adjusted to /usr/bin/swish-e Manually update lxr.conf for permanent setting Checking swishe version ... 2.4.7 I really am clueless at perl but it seems printing "$1" on line 138 of genxref before the $1<5 checks outputs 23, which is the emacs version. ---------------------------------------------------------------------- Comment By: Andre-Littoz (ajlittoz) Date: 2012-02-22 13:08 Message: Hi Yannick, I don't understand how you had no error indication. I checked LXR history: since release 0.10 there is a strong test in genxref to check Exuberant Ctags presence. The test is even buggy since it causes immediate termination instead of proceeding with other tests. With the output you sent, genxref should have die'ed on ctags check. Can run command: genxref --url=//url_for_your_tree --checkonly both for plain ctags and exuberant ctags and send output. You can force a particular ctags instance with proper setting of lxr.conf parameter 'ectagsbin'.

This program is distributed under the terms in ETAGS.README and Exuberant Ctags version output Exuberant Ctags 5.8, Copyright (C) 1996-2009 Darren Hiebert Compiled: Mar 6 2010, 15:35:10 Addresses: <dhi...@us...>, http://ctags.sourceforge.net Optional compiled features: +wildcards, +regex Apparently egemengozoglu does mention to install Exuberant ctags. (go figures I haven't seen this tutorial). Great Program btw. ---------------------------------------------------------------------- Comment By: Andre-Littoz (ajlittoz) Date: 2012-02-22 03:16 Message: I'll modify the preliminary tests in genxref. Could you send the output of command ctags -v or ctags --version on your system? This will help design an adequate test. Anyway, I'm a bit surprised that Ubuntu installs plain GNU ctags. This has not been mentioned by egemengozoglu on his site dedicated to Ubuntu installation (see http://egemengozoglu.com/blog/2011/07/lxr-installation-on-ubuntu-10-10/) ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=390117&aid=3490464&group_id=27350 |
