When I ran my program in pycharm that time my .py file output came in python console mode and also did not see the "Run" option in below(before debug).Please help me to set "Run" option.So I can execute my program using "Run" option.Attaching screen shot.
current is :
Expected:
According to Microsoft, "If [the system] cannot locate the DLL, the system terminates the process and displays a dialog box that reports the error. " This is the result I get when I run my application outside of the command line, but I do not get the same system error when I run the application from a shell environment such as command prompt or powershell.
Is there a way to show the same error message when the application is run from a command line interface?
https://msdn.microsoft.com/en-us/library/aa271571(v=vs.60).aspx
SetErrorMode(GetErrorMode() & ~SEM_FAILCRITICALERRORS);
but I don't think you want to do this, as you do not know in which environment the user will run your application.
It is usually now a good idea to popup a dialogbox in e.g. a service environment.
What is the problem with examining the error code of whatever is failing e.g. LoadLibrary() and reacting to this error?
p = subprocess.Popen([executable_file])
This is only code that I am using to run the python subprocess. However, it has unknown issue that cause my program cannot open the executable file as expected.
executable_file is one file link (PATH) that locate executable program.
Ex. C:\Users\SharkIng\Dev\WhatEverSystem\Builds\Windows\program-123456789-123456789.exe
The python subprocess.Popen should run the program. However, sometime it works and sometime it is not (I did not change any code between this two situation)
OS: Windows 10
Python: 2.7.*
Error: [Error 2] The system cannot find the file specified
BUT: It is working if you manually run subprocess.Popen([executable_file_path_string]) (with same file and path) it work.
WHY this happen?? Is that because some problem with Windows Python? or it is because my setting mess me up?
UPDATE: It is not some reason such as NOT FULL PATH. I can have it working with exact same code. If I ran same code in a python shell, by typing each line of code. It works. But if I put exact same code in a .py file and run it with python file.py, it showing the error
UPDATE 2: Another team member have same error with Windows 7 and Python 2.7.* This code used to work this morning. AGAIN I didn't change anything. That is way I am asking if it is unstable.
There is no problem with subprocess. If you want to run a specified executable, you need to give the full path to that file. The most likely reason you're seeing variable behavior is that sometimes you're in the directory with the .exe, and other times you're not.
I managed to run examples in command prompt after running mavproxy.py and loading droneapi. But when I double click on on my script, it throws me "'local_connect' is not defined", it runs in terminal as was told above, but I cannot run it only with double click. So my question is: Is there any way to run script using droneapi only with double click?
using Windows 8.1
Thanks in advance
You'll want to look at the Running an App/Example section of the guide. For now, you can only run a DroneKit script by launching it from inside the MAVProxy terminal. For example, after launching:
$ mavproxy.py --master=127.0.0.1:14550
MANUAL> module load droneapi.module.api
DroneAPI loaded
You can use the api start command to run a local script:
MANUAL> api start vehicle_state.py
STABILIZE>
Get all vehicle attribute values:
Location: Attitude: Attitude:pitch=-0.00405988190323,yaw=-0.0973932668567,roll=-0.00393210304901
Velocity: [0.06, -0.07, 0.0]
GPS: GPSInfo:fix=3,num_sat=10
groundspeed: 0.0
airspeed: 0.0
mount_status: [None, None, None]
Mode: STABILIZE
Armed: False
I think Sony Nguyen is asking for running the vehicle_state.py outside the Mavproxy command prompt, just like runnning the .py file normally.
I'm also looking for a solution as well.
You can only run dronekit from mavproxy at the moment (its structured as a mavproxy module, there are plans to restructure it), however if you simply want to avoid having to load up MavProxy and then running code manually, you can use the cmd flag:
mavproxy.py --cmd="api start app.py"
I’ve produced a C++ program in Eclipse running on Redhat, which compiles and runs fine through Eclipse.
I thought that to run it separately to Eclipse you use the build artifact which is in the directory set via the project’s properties.
However this executable doesn’t run (I know it’s an executable as I’ve set it to be an executable via the project’s properties and it shows up as such via the ls command and the file explorer).
When attempting to run it using the executable’s name, I get the error:
bash: <filename>: command not found
When attempting to run it as a bash file:
<filename>: <filename>: cannot execute binary file
And when running it with "./" before the file name, nothing happens. Nothing new appears in the running processes and the terminal just goes to the next line as though I’d just pressed enter with no command.
Any help?
You've more or less figure out the first error yourself. when you just run <filename> , it is not in your PATH environment variable, so you get "command not found". You have to give a full or relative path when to the program in order to run it, even if you're in the same directory as the program - you run it with ./<filename>
When you do run your program, it appears to just exit as soon as you start it - we can't help much with that without knowing what the program does or see some code.
You can do some debugging, e.g. after the program just exits run echo $? to see if it exited with a particular exit value, or run your program using the strace tool to see what it does (or do it the usual way, insert printf debugging, or debug it with gdb)
