[Open Babel] - problem with PHP script

[Muriel K. <mur...@gm...>]

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
