In my application I have this piece of code
void showOpenGLInfo()
{
printf("Graphic card vendor: %s\n", glGetString(GL_VENDOR));
printf("Renderer: %s\n", glGetString(GL_RENDERER));
printf("GL version: %s\n", glGetString(GL_VERSION));
printf("GLSL version: %s\n", glGetString(GL_SHADING_LANGUAGE_VERSION));
}
that shows this output on the application log:
Graphic card vendor: Intel
Renderer: Mesa Intel(R) UHD Graphics 600 (GLK 2)
GL version: 4.6 (Compatibility Profile) Mesa 20.3.5
GLSL version: 4.60
I have build Mesa driver 22.0.1 version from source code and glxinfo reports the correct value:
OpenGL version string: 4.6 (Compatibility Profile) Mesa 22.0.1
I don't understand this difference, any tip? Debian 11 Bullseye.
Add some OpenGL information:
OpenGL vendor string: Intel
OpenGL renderer string: Mesa Intel(R) UHD Graphics 600 (GLK 2)
OpenGL core profile version string: 4.6 (Core Profile) Mesa 22.0.1
OpenGL core profile shading language version string: 4.60
OpenGL core profile context flags: (none)
OpenGL core profile profile mask: core profile
OpenGL core profile extensions:
OpenGL version string: 4.6 (Compatibility Profile) Mesa 22.0.1
OpenGL shading language version string: 4.60
OpenGL context flags: (none)
OpenGL profile mask: compatibility profile
OpenGL extensions:
OpenGL ES profile version string: OpenGL ES 3.2 Mesa 22.0.1
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.20
OpenGL ES profile extensions:
Add other information based on comments:

As you can see it links against libstdc++, so I guess another lib need it. How can I check what call is requesting this lib or get more information about the issue?
Thanks.
Run your application as LD_DEBUG=all <cmd-line>, e.g.:

Outputs:

I have vm (centos 7, apache, php 5.4). Small test php script works with no problem. When i try to debug it Netbeans (8.0.2 on windows 8.1) shows 'waiting for connection' and nothing more happens. I am using ssh tunnel from vm port 9005 to host port 9005.

in the settings you have
xdebug.remote_host => localhost
you should have the IP address of the remote machine (the one that runs netbeans), and i assume you should have the debuging port opened on windows firewall, so centos can connect back to that port in your netbeans. i haven't done remote debugging on other machines, always local, but this should work.
XDebug sample static ip/single developer:
The IP of the server is 10.0.1.2 with HTTP on port 80
The IDE is on IP 10.0.1.42, so xdebug.remote_host is set to 10.0.1.42
The IDE listens on port 9000, so xdebug.remote_port is set to 9000
The HTTP request is started on the machine running the IDE
Xdebug connects to 10.0.1.42:9000
Debugging runs, HTTP Response provided

I am setting up memcache setup with cakephp3. I added below in config/app.php
'Cache' => [
'default' => [
'className' => 'Cake\Cache\Engine\MemcachedEngine',
],
]
On the top of the controller I added
use Cake\Cache\Cache;
use Cake\Cache\CacheEngine;
use Cake\Cache\CacheRegistry;
But when I used any function of memcache like Cache::write('variable','value'); etc
It is giving me error
" Error: Cache engine Cake\Cache\Engine\MemcachedEngine is not properly configured. "
The memcached is installed on server.. here is the output
/etc/php.d/memcache.ini,
memcache
memcache support => enabled
memcache.allow_failover => 1 => 1
memcache.chunk_size => 32768 => 32768
memcache.compress_threshold => 20000 => 20000
memcache.default_port => 11211 => 11211
memcache.hash_function => crc32 => crc32
memcache.hash_strategy => consistent => consistent
memcache.lock_timeout => 15 => 15
memcache.max_failover_attempts => 20 => 20
memcache.protocol => ascii => ascii
memcache.redundancy => 1 => 1
memcache.session_redundancy => 2 => 2
Please let me know what is the remaining in configuration. Thanks in advance.
Wrong extension
There are two php extensions related to memcache:
Memcache (older)
Memcached (newer, more features)
The CakePHP Memcached driver relies on memcacheD:
if (!extension_loaded('memcached')) {
return false;
}
Which will result in that error message if it's missing:
if (!$instance->init($config)) {
throw new RuntimeException(
sprintf('Cache engine %s is not properly configured.', get_class($instance))
);
}

when im trying to do trace getenv function i got:
-bash-4.0#/usr/sbin/dtrace -n 'pid$target:libc:getenv:entry' -p 2017
dtrace: invalid probe specifier pid$target:libc:getenv:entry: probe description
pid2017:libc:getenv:entry does not match any probes
-bash-4.0# /usr/sbin/dtrace -n 'pid$target:libc::entry' -p 2017

Why is that happening ? Is there any solution which can make libc functions able to trace via dtrace ?
