What Is A Signal 11 Error And How Do I Fix This?

Hi,

I am not completely new to linux.

My problem is the following:

The signal queue of my process gets filled with time.

With /proc/PID/status --> SigQ 6032/6032 i can see that the queue is full!

And my software is waiting on signals to process data. So I want to know wich signal filled my queue and I am interested to see the attached data of the signal --> sival_int or sival_ptr, I use sigwaitinfo() to read the data.

I want to write a Python script. In order to write it I need to figure out how to access the values associated with my signal level and bit rate.

If I use the following command

Code:

iwconfig | grep 'Signal level'

I get:

eth0 no wireless extensions.

lo no wireless extensions.

Link Quality=70/70 Signal level= -38 dBm


Obviously, I don't want Signal level. I want whatever it happens to be. In this case, it happens to be -38. Ditto Bit Rate...How do I grab -38 from the command line?

Hello guys. When ever i tried to run CRCN protocol i am getting following error:

I was copying the contents of a flash drive to a folder. In the middle of it I got an error message:

'Error splicing file: input/output error'

and then it said 'do you want to skip or retry?' And the "all" button was there too. Anyway, I skipped. When I checked the folder, all my data seemed to be there.

Do you think it was?

I mean, what are the implications of the error message and of my "skipping" it?

Next up, when I looked at the contents of my flash drive all the folders and files have a lock icon on them. I can open the files but I can't edit them. And no, the lock switch on my flash drive is not pressed.

Any ideas?

Thanks.

Dear all;
I run an execute file named "A" gets it's input from a text file "B.inp"
but I face this error:
A < B.inp
: error while loading shared libraries: libquadmath.so.0: cannot open shared object file: No such file or directory

I've downloaded libquadmath and when I want to install it ,the other error said I don't have libgc package!!! but I have libgc!! is it because of existing two different repository that it can't share their information?
my operating system is Centos6;
what shall I do?
Thanks for your attention

After i've execute $ isql -v database dsn name command i get an error in form:"Floating point exception (core dumped)". My comp is Lenovo with 64b AMD processor and my OS is Ubuntu 15.04. As a noobie i suppose the error is in my libmyodbc.so driver. Any advice will be a ppreciated.
