c++ - Setup GDB with QtCreator -

-

I have a simple project to use OpenCV and cmake, and two source files only segmentation. H and segmentation CPP Are there.

Here is cmakefile: 

  project (segment) Cmake_minimum_required (version 2.8) set (CMAKE_BUILD_TYPE debug) set (CMAKE_VERBOSE_MAKEFILE true) if (CMAKE_COMPILER_IS_GNUCXX) Message (position "GCC revealed, compiled flag ") set (CMAKE_CXX_FLAGS" $ {CMAKE_CXX_FLAGS} -O0 -g -std = c ++ 98 -Wall ") Andaif (CMAKE_COMPILER_IS_GNUCXX) find_package (OpenCV required) add_executable (Lulu segmentation.cpp segmentation.h ) target_link_libraries (Lulu $ {OpenCV_LIBS})   
 I created a debug build with the case sent to the limiter: -DCMAKE_BUILD_TYPE = debug However QtCreator still leave the break points, and gdb sh Can not interact with OK:  
  & amp; "Warning: GDB: failed to set controlled terminal: device \ N inappropriate ioctl"   
 How to fix this problem?   
 
 
  project ,  play  and in run settings Check the box that  Play in a terminal . This QT Creator is a program inside XTerm (default) that plays well with gdb and will launch  & amp;  "Warning: GDB: Device for \ N Inappropriate Iioctl: Failed to set controlled terminal" Go away.  
 By default, when launching a debugger, this will bring the Qt Creator to the foreground and thus the terminal will be hidden which will be hidden. To stop this behavior: Go to  Tools ,  Options ,  Debugger  in the  General  tab, uncheck the check box Make sure to bring  the Qt Creator forward in the foreground .  
 If you want to change the terminal, you can do this in  Options ,  Environment  in the  System  section  Terminal  for the original Ubuntu / gnome terminal, set it to  / usr / bin / gnome-terminal -x . The parameters of this setting should be given to the terminal to execute external commands or programs.

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

.net - Creating a new Queue Manager and Queue in Websphere MQ (using C#) -

-
"itemprop =" text "> I am writing applications that use WebSphere MQ to send messages. My unittests (for flow), I want to verify that I have put the correct message on the response queue. I am trying to figure out how to do this. My main obstacle is that I think it might be scary to clear the queue before running in my queue because the same queue can be used by other applications, I thought a decent solution would be a new line The manager will remove the queue for my solidarity and after using it. So my question is: Is it possible to use C # by using queue manager and queue? After the For future reference and future people, who want to make queues. I thought how to make and remove IBM MQ QE (not quenhers) with PCM messaging. It is not very simple, but it can be done. We have implemented it in a library and it is being used to create and delete commands before and after integration tests. The most important part of the code in this library is shown in the...
