[Open Babel] - problem with PHP script

[Muriel Keribin]

Hello,

I have a problem with the PHP script of Openbabel (I must use it for a
project).

I downloaded it from the git repository and I compile with php binding
($ cmake -DBUILD_GUI=FALSE -DCMAKE_INSTALL_PREFIX=/usr/local/openbabel
-DRUN_SWIG=ON -DPHP_BINDINGS=ON .. )
The installation seems to work (two test of the 155 failed, without php all
tests works but I do not think it is a big issue). But I cannot launch the
php script.
I am obtaining the following error :

PHP Warning:  dl(): Dynamically loaded extensions aren't enabled in
/usr/local/openbabel/lib/openbabel.php on line 22
PHP Fatal error:  Call to undefined function new_OBMol() in
/usr/local/openbabel/lib/openbabel.php on line 7466

I tried to preload the libray, (LD_PRELOAD=...) but then it tells me it
cannot read the library file.
I changed the new_OBMol() in new OBMol() in the openbabel.php, and then I
obtain a error of memory allocation.

So I am wondering what I am doing wrong, and if I should change some
options in the "swig"

I am using a virtual machine linux (x86_64-linux-gnu), gcc version 4.8.4,
php 5.5.9 and swig 2.0.11

Thank you and kinds regards,
Muriel

Hi,

I changed this enable_dl boolen in both /php5/apache2/php.ini and
/php5/cli/php.ini . I obtained a more explicit message and I realised that
the library called in the openbabel.php did not had the good name.

I changed openbabel.so by openbabel-php.so (in the
/usr/local/openbabel/lib/openbabel.php file ) and now it is working when
launched in shell (not yet in my browser).

Thank you very much;
Muriel

Re: [Open Babel] - problem with PHP script

[David Hall]

Have you tried setting enable_dl to on? 
http://php.net/manual/en/info.configuration.php#ini.enable-dl

Or adding it as an extension that is loaded when PHP starts?

http://php.net/manual/en/ini.core.php#ini.extension

Note, with either options, you probably need to restart the web server after 
each change.
