ID: 19319 User updated by: vlb@gene.com Reported By: vlb@gene.com -Status: Bogus +Status: Open Bug Type: *Configuration Issues Operating System: Tru64 Unix (n/a) PHP Version: 4.2.2 New Comment: They _aren't_ lumped into /usr/local... if they WERE PHP wouldn't break. A user has a reasonable expectation that if --with-foo=DIR is specified,, then DIR _will_ be used to find parts of foo. Not used sometimes at PHP's whim and skipped over othertimes. AND phpinfo is lying. Ether fix it or remove the incorrect information from the info screen. People are _going_ to want to use test versions of libraries, etc that are in specified places other than the "standard" locations (or /usr/local/*). This is not a problem that is going to be specific to me. Previous Comments: ------------------------------------------------------------------------ [2002-09-10 11:07:43] rasmus@php.net "Standard ld path" from my original statement also includes directories that you point configure at for other stuff. If you want full control you need to put these libraries into their own directories and not lump them all into /usr/local/lib and expect PHP to sort out your mess. ------------------------------------------------------------------------ [2002-09-10 10:59:48] vlb@cfcl.com >If you do have a version on your standard path, you can be pretty sure that it is the one that gets used no matter what. That's actually NOT true unless the one on the standard path is a .so and the "new" one (the one you want) is a .a. Trust me; I've done a LOT of research into this lately :( ------------------------------------------------------------------------ [2002-09-10 10:59:13] rasmus@php.net The configure script does check one at a time, but on the final link we have to put all the -L entries in there. You more than likely have other libraries that live in /usr/local/lib so they end up adding a -L/usr/local/lib to the link line. This happens with every package I know of and is just the way stuff works. ------------------------------------------------------------------------ [2002-09-10 10:58:04] vlb@gene.com >As with any other library, if you are going to have >multiple versions, make sure none of them are on the >standard LD path so you have full control over what gets >used. But that's exactly the point! The librarys is _not_ in the standard path and I _exect_ full control. I specified the location in my --with-imap=DIR configure option. I AM NOT GETTING THAT CONTROL I'm not getting it because PHP is being linked with ALL libraries at once at that means there could be conflicts. In my case, the --with-kerberos=DIR location is overriding my --with-imap=DIR location. As you point out ... "if you're going to have multiple versions...you...have full control". Well, I expect full control and I'm not getting what I expect. That's rather the definition of a bug, isn't it? :-) ------------------------------------------------------------------------ [2002-09-10 10:52:57] vlb@gene.com Given that PH claims to support configure options of the form --with-foo=DIR where DIR is the location into which foo and its components (e.g. .a or .h files) have been installed THEN the user has a reasonable expectation that the components of foo (as fiund under DIR) will actually be used in compiling and linking the components of PHP. If this is not possible, then PHP should not claim to have used the files from DIR. > Don't have many versions in there. Simple as that. The reason that ld has a specific search order, modifiable by the ordering of -Ldir flags is designed to handle just this situation. Systems with multiple copies (e.g. one in production, one in test) of libraries, headers, and binaries, are not unusual. Either link in the libraries specified by --with-foo=DIR one at a time to ensure that you get the correct one or figure out a way to have phpinfo tell the truth or document the bejeebers out of this. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
