How do I configure $this->cwd for symfony2 framework - php

Question

I am new to Symfony and I was assigned a Symfony 2 project.Now I am facing some problem with app/console server:run.
The project is a working system, therefore the problem should be because of my limited knowledge in Symfony framework.
this is what I keep getting
proc_open() : CreateProcess failed, error code - 267 in C:\xampp\htdocs\xxx\vendor\symfony\symfony\src\Symfony\Component\Process\Process.php on line 246.
line 246 is this part
$this->process = proc_open($commandline, $descriptors, $this->processPipes->pipes, $this->cwd, $this->env, $this->options);
I have tried changing the $this->cwd to "C:/xampp/htdocs/xxx", it can run but it will have another problem which is after I visit localhost:8000, it shows this
Warning: require(app_dev.php): failed to open stream: No such file or directory in C:\xampp\xxx\vendor\symfony\symfony\src\Symfony\Bundle\FrameworkBundle\Resources\config\router_dev.php on line 30
Fatal error: require(): Failed opening required 'app_dev.php' (include_path='.;C:\xampp\php\PEAR') in C:\xampp\htdocs\xxx\vendor\symfony\symfony\src\Symfony\Bundle\FrameworkBundle\Resources\config\router_dev.php on line 30
Any ideas what is wrong?
EDIT:
I have updated all my files as suggested my Matteo, a few issues came up with the vendors and I have solved it for new (hopefully). However now I am stuck at another problem which is this
The given document root directory "C:/xampp/htdocs/xxx/app/../web" does not exist.
As mentioned in the comments, I do not have a folder called "web". It was renamed to public. I have already changed the composer.json but it does not seem to do anything.

If I type app/console --version in cmd, it shows Symfony version 2.6.1 - app/dev/debug
Please help me out.

It's a bug as described here. It is resolved in the current framework version (2.6.1).
So the solution is to upgrade to the current version. You can verify in the UPGRADE files on the github repo is something is changed but there anren't BC (Break Compatibility).
In addition, your current framework version (2.4.2) is out of support so is a good moment to do this task.
In general is a good practice to upgrade to the last stable version of the framework. Take a look at the sf2 release roadmap for the release process and for the end of support of the various framework release.
Hope this help
