[CWB] how to fix Base class package "CWB::CEQL" is empty

Wed Sep 18 19:10:18 CEST 2024

Solved!!
the proc_open() generating the error is located in
/home/git/TEITOK/common/Sources/cwcqp.php

The parameters for proc_open() should be:
1. The command to run ($cqpapp.' -r '.$registryfolder.' -c').
2. The descriptorspec defining how the process's standard input, output,
and error streams will be handled.
3. An array to store the pipes ($this->pipes here).
4. The working directory (optional; here it is '-c').
5. The environment variables (optional, passed as $env).

Currently, in proc_open() function is '-c' as the working directory, which
doesn't seem correct. The -c flag should probably be part of the command
(if that's what it's meant for), not the working directory.

To fix the working directory argument I tried:
$this->prcs = proc_open($cqpapp.' -r '.$registryfolder.' -c',
$descriptorspec, $this->pipes, null, $env);

And this did it...
