After installation fasttext and install php module I see error: Warning: PHP Startup: Unable to load dynamic library 'path_to_fasttext/fasttext.so' - libfasttext.so: cannot open shared object file: No such file or directory in Unknown on line 0

I'm not understand what I should to do then solve this problem. Please help me.

I've tried to install fastText-php in the official php docker image (php:7.4-rc). But didn't succeed. Perhaps there is an environment variable missing, where the extensions looks for the shared object?!?

What I've done

1. Installed curl, build-essential, cmake via apt-get
2. Downloaded fastText-0.2.0.zip and the source tarball of the master branch of fastText-php and installed it according to the readme.md.

Error message

PHP Warning:  PHP Startup: Unable to load dynamic library 'fasttext.so' (tried: /usr/local/lib/php/extensions/no-debug-non-zts-20190529/fasttext.so (libfasttext.so: cannot open shared object file: No such file or directory), /usr/local/lib/php/extensions/no-debug-non-zts-20190529/fasttext.so.so (/usr/local/lib/php/extensions/no-debug-non-zts-20190529/fasttext.so.so: cannot open shared object file: No such file or directory)) in Unknown on line 0

Dear Takahashi-san,

It seems I've run into a similar issue as Issue #2:
I've installed fasttext 0.1.0 using cmake and it's running fine on the command line, alas after following your instructions for installing the php-bindings I still get this error:

PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib/php/20151012/fasttext.so' - libfasttext.so: cannot open shared object file: No such file or directory in Unknown on line 0
PHP Fatal error:  Uncaught Error: Class 'fastText' not found in /home/aqbanking/fasttext.php:3
Stack trace:
#0 {main}
  thrown in /home/aqbanking/fasttext.php on line 3

any ideas?

On line :
$ftext = new fastText();

thrown error :
PHP Fatal error: Uncaught Error: Class 'fastText' not found in ...

Note : no error on extension loading.

Configuration info

I have followed the installation instructions ... but replaced 0.9.1 by 0.9.2. No issue during installation. (ubuntu 18.04 / PHP 7.2)

Added in php.ini :
extension=/home/parallels/fastText-php/modules/fasttext.so

Added in '/etc/environment':
PATH=" (...) :/home/parallels/fastText-php/modules"

Takahashi-san,

fastText was installed without a problem but during make session of fastText-php, I encountered the following error message;

/my-dir/fastText-php/json.hpp:67:10: error: #error "unsupported GCC version - see (URL is omitted)

My GCC version is 4.8.5-36.
What's going on and let me know how to resolve this situation.

Thanks in advance,
Kiyoshi Hirose.
