PHP 5.x compatibility - undefined symbol: zend_error_noreturn

[remicollet]

Since 1.2.0, package.xml states 5.5 is supported

PHP Warning:  PHP Startup: Unable to load dynamic library '/builddir/build/BUILDROOT/php-pecl-awscrt-1.2.0-1.el7.remi.5.5.x86_64//usr/lib64/php/modules/awscrt.so' - /builddir/build/BUILDROOT/php-pecl-awscrt-1.2.0-1.el7.remi.5.5.x86_64//usr/lib64/php/modules/awscrt.so: undefined symbol: zend_error_noreturn in Unknown on line 0

zend_error_noreturn was introduced, as public API in PHP 7.0

We do run tests for php 5.6, here

But, yeah, seems like we have issue for php5.5

PHP 5.6 is also affected See explanation on pr #96

I mean we have test for php5.6, that builds and runs the code. But, I see your fix should be needed for php 5.x, just kind wander why it's not caught by our CI for php5.6.

• perhaps php build doesn't-have the default "visibility = hidden" option
• perhaps the call is not covered by the tests

Real builds (packages) for real distributions use lot of security build options.

I printed php --version from our CI that used shivammathur/setup-php to setup the exact version of php. I still cannot reproduce the issue with CI.

I did reproduced it from my local linux machine that used php55 from here, with that I also printed the version of php, which is:

php55 --version

could that be related to with Zend OPcache v7.0.6-dev?

[remicollet]

No this is related to PHP build options used in Linux distribution for security and performance.

See: https://github.com/php/php-src/blob/PHP-7.0/Zend/zend.h#L86 this is in public API (ZEND_API) See: https://github.com/php/php-src/blob/PHP-5.5/Zend/zend.h#L294 this is not public

[TingDaoK]

Okay, I see. I tried to install php using ondrej/php, which is used by setup-php action here.

Now, I cannot reproduce that error.

Yeah, I think it's very likely that php build doesn't-have the default "visibility = hidden" option. :)

I'll create an issue to shivammathur/setup-php and see if they can fix it in order to catch this kind of issue from our CI.

the new 1.2.1 version should solve the issue. https://pecl.php.net/package/awscrt/1.2.1
