Hi (again)

running cross-link I got that:

>> with my user
>>
>> ./cross-link
>> mem=0x7f0d630488e0, alloc_size=8192
>> Init memory pool returns 1808 bytes

....


the permissions are:
$ ls -la /var/run/xenomai/
total 0
drwxr-xr-x  3 root root  60 nov 23 16:03 .
drwxr-xr-x 24 root root 860 nov 24 11:12 ..
drwxr-xr-x  2 root root  40 nov 24 11:12 root

so, IMHO this folder should belongs to xenomai group and permisions g+rw. Right?

Changing the permissions manually solved it. It's something about the packaging
or the library?

Yes, I don't have rtser0 entry in /dev/rtdm/. Who does create it?

Also, /dev/cpu_dma_latency should not belongs to xenomai group?

Best regards,

Leopold
