Hi,

I have followed the instructions at:

http://github.com/eduardok/libsmbclient-php/blob/master/README

and have been able to succesfully "phpize", "configure" and "make".
However, I get errors attempting to "make install". A module
"libsmbclient.so" is created (so I presume that I could complete the
installation by hand). However, it would be good if the issue
affecting "make install" could be resolved. I am on CentOS 5.3. (It
looks like a dynamic shared object is not being built, but attempts
are being made to install it ?)

Below is the output of my build attempt:

First clue of something wrong with time.

Definite message about time problems.

Can you fix the time in your machine or at least run a: touch *

I guess you could be also using an NFS server. If that's the case
please make sure the NFS server's time matches this machine's time.
You could use NTP on each one: ntpdate nz.pool.ntp.org

Let me know what happens.

Thanks for the reports,

Ah - I did notice those but thought they were benign :-)

Resolved with a

# find . | xargs touch

Not on an NFS share - but I completed the git check out and created a
tar of the directory on an off-site box (then uploaded to my
production environment where I attempted the build). There will be a
clock skew somewhere as a result of this process.

Looks much better. Although when I attempt a "make test", I get:

PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/
20060613-debug/dbase.so' - /usr/lib/20060613-debug/dbase.so: cannot
open shared object file:

I did try to find where this library is supposed to be on CentOS with
a:

# yum provides '/usr/lib/20060613-debug/dbase.so'

(which gave no hits) and then a yum provides 'dbase.so'

which gave:

php-common-5.1.6-27.el5.i386 : Common files for PHP
php-dbase-5.1.6-15.el5.centos.1.i386 : Standard dBase module for PHP
applications
php-common-5.1.6-27.el5.i386 : Common files for PHP

Trouble is all these rpm's are installed.

Is this important, or will libsmbclient-php run without the dbase.so
shared object ?

>

No problems - Thank you for your quick answers!

I haven't tried loading limsmbclient-php as an extension yet (still
wanting to get the build correct).

Do you have a code snippet for copying a remote file from a CIFS
box ? i.e. I'm after the SMB/CIFS "equivalent" to

scp remoteBox:/foo /tmp

(i.e. copy a file "foo" from "remoteBox" to the local filesystem - but
using CIFS as opposed to SFTP).

(Even better, I want to serve up a file for HTTP download on demand
using a *nix box as a frontend to a backend CIFS box. If you know of
a way that I can do this without having to locally cache it on the
*nix frontend this would be appreciated.)

Thanks for your help.

Yeah, it's kinda weird that stuff doesn't work because of that. I'm
pretty sure there's a good explanation. Maybe one of these days I'll
actually do some research and find out :P

Yeah, so that box is in the future.

Oh, I forgot about that. You can safely ignore and simply make install now :)

Yeah, that's why I had to use libsmbclient-php. I was doing not only
download but upload to a samba server's share.

Note that you could also do: smbclient //sambaserver/share -N -p -c
"prom ; cd dir1/dir2 ; get myfile.zip"

That's the type of thing I was using before I implemented libsmbclient-php.

Basically you're gonna have something like:

$fh = smbclient_open($url);
if(!$fh) return;
while($str = smbclient_read($fh, 4096))
$file_contents .= $str;
smbclient_close($fh);

$url should be in the format: smb://user:pass@server/share/file.txt

Hi Eduardo,

I have been able to get your test script "libsmbclient.php" up and
running! Works great. An excellent link between PHP and Samba :-)

A couple of comments / observations:

1. Executing "libsmbclient.php" under httpd for me initially resulted
in:

Fatal error: Call to undefined function smbclient_opendir() in /var/
www/html/libsmbclient-php/libsmbclient.php on line 31

Taking the commented line "//dl("./.libs/libsmbclient.so");" as a
hint, I tried:

dl("libsmbclient.so");

which resulted in libsmbclient-php working correctly. Perhaps either
ship this example script as above (i.e. with an uncommented line
dl("libsmbclient.so");) or add a comment to the README ?

2. On stderr, the following is being written for each script (executed
interactively):

PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/
20060613-debug/dbase.so' - /usr/lib/20060613-debug/dbase.so: cannot
open shared object file: No such file or directory in Unknown on line
0

This will be related to the dbase.so warnings observed with "make
test" as discussed above.

Otherwise - looks good.

Regards,

Patrick

The dl() line is only needed if you want to manually load the
library/extension instead of using php.ini as described in README.

I don't get those on my Mandriva (and I don't have a dbase.so), but I
remember seeing that before, perhaps it was on my Slackware.
Anyway... once I'm able to reproduce I'll take a look.

Keep in mind that there are many functions from samba's client library
that weren't implemented in libsmbclient-php yet, so if you seem to
need anything that's not supported let me know and perhaps I can add
(e.g: chmod, print functions, etc).

Thanks again,
