In commit;a=commitdiff;h=85a511d2c1b7d7489630d7e2d1112bddd4e20203

the calls to zend_signal_startup() where moved from Zend/zend.c into the individual sapi files. IMHO this means, that zend_signal_startup() needs to be declared and defined using ZEND_API in Zend/zend_signal.h and Zend/zend_signal.c.

I noticed this, because I changed the PHP build to use a common shared library for the different SAPIs. It likely is not noticed when linking all zend stuff statically into the binary sapi modules.

I should add I'm using the configure flag --enable-zend-signals to enable zend signals.

The only place that this function should be called is in the SAPI layer, since all usable SAPI's are distributed with PHP, there doesn't seem to be a legitimate need to export the symbol.

We are building PHP as a static embed library and linking it afterwards into our project. This worked in PHP 5.6. Unfortunately in PHP 7.x we get the same error, because zend_signal_startup is not exported. Any chance to revise your decision? Do i have any major drawbacks when compiling without signals? (This works around the issue)

Thanks in advance!

If we are not going to fix this bug, will we accept a patch to properly wrap zend_signal_activate with #if ZEND_SIGNAL? The call to zend_signal_deactivate is wrapped in it. We should be consistent.

Also, currently --disable_zend_signals is useless. See the report in for as to why.
