I want to run the Ghostscript command for drawing lines from a C program. I am using execlp() system call to run the command. When I am trying to run the command for line drawing from terminal/C, I am getting the same error like this:

The command I am running for drawing is this postscript command(drawing a line)

You need to add the flag "-c".
The gs command will then be
gs -c 100 100 moveto 300 300 lineto closepath stroke

Moin,
I used the Oracle-Profiler from the DBMS_HPROF package a lot to find out where the right queries to optimize.
This time I ran into a problem, even though it seems to be setup correctly.
Profiling even complex parts of the application I try to optimize produce trace files that are processed without any issues by the plshprof tool that produces the HTML reports from the trace files.
When I profile this one particular procedure it produces a trace file that seems ok (it is properly ended and so).
But when I use plshprof on it, out comes always an HTML file that ends after 12542 Bytes (no, the drive is not full).
I tried executing an additional query before the problematic procedure and the result was that the HTML ended again after exactly 12542 Bytes.
In one case the HTML ended in the middle of an attribute of a tag in the other before the > of the ending tag.
From the beginning to the EOF the HTML report looks ok!
Windows Server 2019 Build 1809
Oracle Database Version: 19c (19.3) Standard Edition 2
This is how I called the profiler and the procedure:
BEGIN
DBMS_HPROF.START_PROFILING(LOCATION=>'PLSHPROF_DIR', FILENAME=> 'test1.trc');
SOME_PACKAGE.SOME_PROCEDURE();
COMMIT;
DBMS_HPROF.STOP_PROFILING;
END;
/
This how I called it:

Did anybody ever ran into this problem and/or found out what is/was the problem?
I can imagine it has to do with the complexity of the function tree called but I am not able to figure out where to start.
The procedure uses several packages and reads and writes from and to tables and views with triggers which also call functions that do the same.
Thanks in advance!

I made the changes required in the euroc_eval_examples.sh and change it by the dataset path!
Can someone help me with this issue?
Had the Same prob here.
I just had the path and its syntax all messed UP.
Try to run the whole thing with this command:
./Examples/Monocular/mono_euroc ./Vocabulary/ORBvoc.txt ./Examples/Monocular/EuRoC.yaml "$pathDatasetEuroc"/MH01 ./Examples/Monocular/EuRoC_TimeStamps/MH01.txt dataset-MH01_mono
And where it says "$pathDatasetEuroc" make sure you put the right path before MH01, in which there should only be the mav0 folder.
In your case should be /home/yz2qmq/ORB_SLAM3/V1_01_easy
----> ./Examples/Monocular/mono_euroc ./Vocabulary/ORBvoc.txt ./Examples/Monocular/EuRoC.yaml /home/yz2qmq/ORB_SLAM3/V1_01_easy/MH01 ./Examples/Monocular/EuRoC_TimeStamps/MH01.txt dataset-MH01_mono
That at least worked for me.
It is exactly the same thing as running ./euroc_examples.sh, and you will realize it easily if you open and read briefly euroc_examples.sh.
(This btw is a guide which actually worked for me only after following it blindly :( https://www.ybliu.com/2020/07/ORB-SLAM3-demo.html)
I have a Mac and just installed LaTeX and the editor Texmaker. To use the Arial font I installed it via MiKTeX Console. I also found out that by doing so, the files for the installed packages lay here:
"/Users/Mirko/Library/Application Support/MiKTeX/texmfs/install/tex/latex"
My problem is that the Editor (TeXMaker) still doesn't find the Arial-Font.
Here is my Code:
\documentclass[pdftex,openany,11pt,twoside,a4dutch]{report}

\end{document}
and here is the Error:

But the folder arial and the file arial.sty are in the above mentioned folder.
In the MikTeX-Console I already entered the folder to Directories > Settings
I thankful for every help!
Thanks and greetings!

texmaker is not using the miktex distribution for which you installed the uarial package, but a texlive distribution which seems to be also installed on your computer. In the long run it would be best to only have a single tex distribution on your computer to avoid such problems. For mac I would suggest to keep the texlive distribution and get rid of miktex, because texlive is used by most mac users and therefore well tested compared to miktex for mac.
Now you could force texmaker to use your miktex installation by modifying the texmaker preferences, but the easier way to use Arial in your document is to switch from pdflatex to xelatex or lualatex and directly use the arial font installed on your computer

No results, this could be for a number of reasons. The most common reasons are:
1) missing PDBs for the assemblies that match the filter please review the
output file and refer to the Usage guide (Usage.rtf) about filters.
2) the profiler may not be registered correctly, please refer to the Usage
guide and the -register switch.
I have tried setting the Jenkins to run under my ID and allowed it to interact with the desktop.
Can someone point me in the right direction to get it running please?
Ahh so I found the answer from this question, I just needed to move a quote to give:
"C:\Program Files (x86)\OpenCover\OpenCover.Console.exe" -register:user -target:"C:\Program Files (x86)\NUnit.org\nunit-console\nunit3-console.exe" -"targetargs:C:\workspace\Extensions\Extensions\ExtensionTests\bin\Debug\ExtensionsTests.dll -result=TestResult.xml;format=nunit2" -filter:+
Which works!
I am working on Pintos OS project. I get this message:
Page fault at 0xbfffefe0: not present error writing page in user context.
The problem with Pintos OS project is that it won't simply tell the line and method that caused the exception.
I know how to use breakpoints/watchpoints etc. but is there any way to step right to it without going through the WHOLE flow and ALL OS files line by line so that I could jump into line that caused exception and put breakpoint there? I looked at GDB commands but didn't find anything.
When I debug this project I have to step through the whole program until I find that error/exception which is very time consuming. There is probably a faster way to do this.
Thanks.

to have the GDB debugger run and stop at the desired location:
gdb filename <--start debug session
br main <--set a breakpoint at the first line of the main() function
r <--run until that breakpoint is reached
br filename.c:linenumber <--set another breakpoint at the desired line of code
c <--continue until second breakpoint is encuntered
The debugger will stop at the desired location in the file, IF it ever actually gets there,
When I debug this project I have to step through the whole program
until I find what caused error/exception which is very time consuming.
There is probably a faster way to do this.
Normally what you would do is set a breakpoint just before the error. Then your program will run at full speed, without your intervention, until it reaches that point.
There are several wrinkles here.
First, sometimes it is difficult to know where to put the breakpoint. In this case I suppose I would look for the code that is printing the message, then work backward from there. Sometimes you have to stop at the failure point, examine the stack, set a new breakpoint further up, and re-run the program.
Then there is the mechanics of setting the breakpoint. One simple way is to break by function name, like break my_function. Another is to use the file name and line number, like break my_file.c:73.
Finally, sometimes a breakpoint can be hit many times before the failure is seen. You can use ignore counts (see help ignore) or conditional breakpoints (like break my_function if variable = 27) to limit the number of stops.
