[Ruslan Osmanov]

Please attach the output of the whole build process including configure, make and make test commands. Just how exactly the extension is built?

Also please attach the output of php -i command.

[Van Huynh]

I had attached error file. Please check. I try build pecl-ev, but sample error. Thanks you.

[Van Huynh]

And I had attached php -i file. Thanks you.

[Ruslan Osmanov]

For the sake of a test, try to comment out everything from /etc/php-7.1.d/z-20-sockets.ini, then replace contents of /etc/php-7.1.d/z-30-event.ini with the following:

extension=sockets.so
extension=event.so

Try to run some PHP, e.g.: php script.php.

[Van Huynh]

Thanks you. I try edit z-20-sockets.ini and z-30-event.ini, and restart httpd. But when run ratchetphp, had php error.

Error - Call to undefined method Event::register() in COREPATH/classes/fuel.php on line 192

[Ruslan Osmanov]

If you are trying to configure Ratchet/React PHP, then you need to configure the CLI SAPI -- there is no need in an "httpd" daemon (which is likely running Apache2 SAPI).

Also, the Event extension is designed to work in CLI SAPI only.

Have you tried to run php -m after the suggested modifications? Can you see the "event" item there?

[Van Huynh]

Thanks you. I can see "event". I think problem, php_sockets_le_socket no found. but sockets.so installed and sockets.so load before event.so. (i try build pecl-ev, but same error.)

I wonder why PHP tries to load event.so from '/home/ec2-user/libevent/osmanov-pecl-event-d379aaef9469/modules/event.so'. Have you installed the library there?

Did you try to test a CLI script apart from running make test?

How exactly did you install the event extension? (Note, pecl-ev you are referring to is a different extension.)

[Van Huynh]

I ./configure and make, I running make test, but had error. After i make install, Installing shared extensions: /usr/lib64/php/7.1/modules/. I tries run php (ratchetphp use event lib).

/bin/sh /home/ec2-user/libevent/event-2.4.0/libtool --mode=install cp ./event.la /home/ec2-user/libevent/event-2.4.0/modules
libtool: install: cp ./.libs/event.so /home/ec2-user/libevent/event-2.4.0/modules/event.so
libtool: install: cp ./.libs/event.lai /home/ec2-user/libevent/event-2.4.0/modules/event.la
libtool: finish: PATH="/sbin:/bin:/usr/sbin:/usr/bin:/sbin" ldconfig -n /home/ec2-user/libevent/event-2.4.0/modules
----------------------------------------------------------------------
Libraries have been installed in:
   /home/ec2-user/libevent/event-2.4.0/modules

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the `LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the `LD_RUN_PATH' environment variable
     during linking
   - use the `-Wl,-rpath -Wl,LIBDIR' linker flag
   - have your system administrator add LIBDIR to `/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

[Ruslan Osmanov]

It would be better to have an SSH access to that machine, or a Docket container. Otherwise, I can only guess.

Please locate the sockets.so file, go to the directory containing the file, and run:

nm -D sockets.so

I'd like to look at the output.

[Van Huynh]

sockets.so no found. I want send you SSH access. can you send your mail to me? Thank you.

nm -D sockets.so

nm: 'sockets.so': No such file

But

sudo find / -name sockets.so
