Re: Re: GD extension warning when installing a package

Hi all, After a good night, i've finally clear ideas, and have a GOOD NEW: I FOUND ORIGIN OF MY PROBLEM, and i'll try to explain to avoid all PEAR developpers to get again the same problem . I've run lot of tests and discovered : if your package (to install) has a PHP extension dependency, such as GD YOU CANNOT USE the version# compare feature; Why ? Have a look on file Dependency.php,v 1.36.4.1 2004/12/27 07:04:19 cellog (lines 260-277) It's the same for PEAR 1.3.4 and 1.3.5 (i've not investigated for 1.4.0a1) And read lines of checkExtension() method. This method is called when install a package that has a dependency like : for Image_Color 1.0.1

      <dep type="ext" rel="has">gd</dep>

for HTML_Progress 1.2.0

      <dep type="ext" rel="ge" version="2.0.1" optional="yes">GD</dep>

for Image_Graph 0.2.1, and Image_Tools 0.1

      <dep type="ext" rel="has" version="2">gd</dep>

for Image_Graph 0.3.0dev4

      <dep type="ext" rel="has" optional="no">gd</dep>

I've a warning message because GD extension does not exists; it's gd (TAKE CARE it's case sensitive) warning message is created by line 251: 'GD' PHP extension is recommended to utilize some features When i try with gd in lowercase

      <dep type="ext" rel="ge" version="2.0.1" optional="yes">gd</dep>

i get warning message created by lines 272-273 'gd' PHP extension version >= 2.0.1 is recommended to utilize some features Why ? see Version compare in details made (line 267)

        if (!version_compare("$ext_ver", "$req", $operator)) {

between $ext_ver (line 264) current version of ext. gd ($name: arg #2)

        $ext_ver = phpversion($name);

and $req (method arg #3) ( Greg, there are few typo error on this method phpdoc tags: * missiong out arg#1 $errmsg * mispelling arg#3 $req_ext_ver/$req * forgot (optional) for args #3,4,5) ) It's returns for my config (with windows PHP 4.3.10)

        $name = 'gd';
        $ext_ver = phpversion($name);
        $php_ver = phpversion();

        var_dump($php_ver);  ==> string(6) "4.3.10"
        var_dump($ext_ver);  ==> boolean(false)

probably a PHP bug ?! So with dep

      <dep type="ext" rel="ge" version="2.0.1" optional="yes">gd</dep>

PEAR will compare extension with versions 2.0.1 and boolean false ==> result is false TO RESUME: 1. do not use version compare feature (rel="ge") with PHP extension 2. respect case (lowercase) the right line to code is

      <dep type="ext" rel="has">gd</dep>

and not :

      <dep type="ext" rel="ge" version="2.0.1" optional="yes">GD</dep>

or

      <dep type="ext" rel="has" version="2">gd</dep>

BTW in the last case the problem is not seen because, checkExtension() method stop to compare (line 258) with a rel="has" I hope it will clear the situation, and help all of you to avoid such problem in future ! regards Laurent Laville Firman Wandayandi a écrit :

Uh, i got some stuff accidentically, if we run php on console, PHP looking for php.ini at the working directory first and the SYSTEMROOT. Seem this problem still not found a solution, what happened with Laurent's PEAR. Why must be GD, i think Laurent should be test another package that depend on another extension (No GD), we clearing this situation, that is a PEAR bug or what? BTW, take care yourself Laurent, happy travelling! Do some test again when you come back.
