PHP agent compilation error

Hello,

I am trying install PHP agent for APM and doing steps following documentation. https://github.com/elastic/apm-agent-php/blob/master/docs/setup.asciidoc

But it gives error when executing 'make' command.

[root@webapp ext]# make

Hi @tumenzul - welcome to the forum!

What PHP version do you use? Is it possible that the root cause is the same as at https://github.com/elastic/apm-agent-php/issues/124?

tumenzul · August 20, 2020, 9:12am

I am using 7.1.33. This issue same as me.

Thank you @Sergey_Kleyman
