XDebug profiling in PHP - can't get output

There is also problem with /tmp folders on some distributions, i couldnt get output on centos 7 and then i found this

So, i have set

xdebug.profiler_output_dir=/home/jirka/profile

chmod 777 /home/jirka/profile and its ok now.

Comment out xdebug.profiler_output_dir and xdebug.profiler_output_name and see whether you can find the output under /tmp/.

Another possible cause of this issue is the permissions on the folder of profiler_output_dir.

Adding write permissions to the group and owner resolved the issue for me:

sudo chmod go+w /home/dimitris/cachegrind/
