We have an issue with pcntl support for PHP 8.4

[SanderJ]

We have an issue with pcntl support for PHP 8.4:

I have added

--enable-pcntl

to

/usr/local/directadmin/custombuild/custom/php/configure.php84

, and did a new build for php.
Custombuild logs shows:

checking whether to enable pcntl support... yes

Also, the custom php84 config file is used by DirectAdmin:

[root@server1 ~]# da build used_configs
PHP 8.4 php.ini file: /usr/local/php84/lib/php.ini
PHP 8.4 configuration file: /usr/local/directadmin/custombuild/custom/php/configure.php84

But after the rebuild, there is no pcntl support for php8.4. This sollution works fine for php8.2 / php8.3.

DirectAdmin: v1.675 bcd6e3bf4a4dbfaeb423aae49ad2a0fd77206d7f
OS: AlmaLinux release 8.10 (Cerulean Leopard)

It should work. I've got it working on AlmaLinux release 8.10. How do you check its working on your end?

I have the same custom config for php8.3, and that is working just fine.

Looking at the build date of php8.4, it seems that the binary was not rebuild. It should be dated to April 17th. Custombuild logs show "Build complete." and no errors on the last build.

it seems that the binary was not rebuild.

And what if you run

da build php 8.4

?

What final 10-20 lines will be?
