We have an issue with pcntl support for PHP 8.4:

I have added
Code: 
--enable-pcntl
to
Code: 
/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
Click to expand...
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
Click to expand...

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.

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'

   - 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'

more information, such as the ld(1) and ld.so(8) manual pages.

But when I look at the binary:

Those final lines from redis-pecl installation, not PHP. You will need to copy and show lines from PHP installation. In order to captcha the lines you might redirect output to a file, or disable PHP extensions temporary.

@SanderJ
First, we need to recovery build system, remove '--enable-pcntl' and re-build again, then check script building success or not.
Code: 
stat /usr/local/php84/bin/php

if remove '--enable-pcntl' from configuration and still not success, then we need to dig more than this.
 
Found probably the same issue on Debian 12.10 when tried to upgrade PHP 8.4.5 to 8.4.6.

Though the installation/compilation process did not report any error

See: the Zend OPcache v8.4.6 - UPGRADED, but PHP version never upgraded.
Fixed by renaming
Bash: 
mv /usr/local/php84 /usr/local/php84.OLD
and re-installing PHP 8.4

Once PHP 8.4.6 gets installed, it can be recompiled and updated by usual means. I mean that, the commands:

Bash: 
mv /usr/local/php84 /usr/local/php84.OLD
da build php 8.4

# ... some time later ...
da build php 8.4

the second attempt will update PHP without an issue.


Probably @fln could advise
 
@zEitEr, would be great to have access to this server to investigate this further.

We rely on PHP make install command to replace the binaries. If there are circumstances when the binaries would not be replaced it would be good to track it down and fix it. Our long term goal is to make PHP to completely replace whole /usr/local/php{nn} directory, but we have not reached it yet. Right now new PHP files are being merged over the old ones.

The PHP version was already upgraded, so I can not say whether or not it can be replicated. I will update the thread or a ticket if it can be reproduced.
