I am working on OMNET++ project called Exfogsim and there is no problem when I run the simulation with (Run), but when I am trying to Debug it the following error appears:
with the following error
Error with command: gdb --version
Cannot run program "gdb": Launching failed
Your simulation was terminated with exit code: -2147483645. The hex representation of this number is: 0x80000003. So try search how to deal with the Windows exception 0x80000003, for example take a look at that one.

I'm using vscode on Windows, and use mingw-w64 as compiler. my test code are as follows:
vector<string> words = {"SEND", "MORE"};
string result = "MONEY";
when I debug it, I can print 'words' and 'result' object correctly, but when I try to use subscript, something wrong occured:
print words[0] // gdb: Could not find operator[].
and more seriously, when I try print string's subscript, gdb just crashed:
print result[0]
// ERROR: GDB exited unexpectedly with exit code -1073741819 (0xC0000005). Debugging will now abort.
Those errors occurred samely whether debug with vscode or use gdb in cmd shell manually.
However, when I debug on linux platform using gdb, it works perfectly. That makes me confusing. I can't find if there's any bug in mingw, or maybe gdb doesn't support windows platform well. My g++ and gdb version are 8.1.0. I have tried some older version but all those have same problems. Is there any good solution, or shall I just give it up?
Clean your path environment and PY_HOME.
I downloaded the latest version of the C++ ide from eclipse called oxygen. I am trying to do a basic debug test with an application on windows 10 but get this error message:
Error in final launch sequence
Failed to execute MI command:
-file-exec-and-symbols C:/Users/Owner/eclipse-workspace/Hello/Debug/Hello.exe
Error message from debugger back end:
"C:/Users/Owner/eclipse-workspace/Hello/Debug/Hello.exe": not in executable format: File format not recognized
"C:/Users/Owner/eclipse-workspace/Hello/Debug/Hello.exe": not in executable format: File format not recognized
I added the path to the gdb executable in the mingw folder but I am still getting that error message.
I am using Codeblocks for the first time to run a cpp program. While compling the program an error occurs, I want to know the line number from the program where the error is evoking or in other words I want to see the stack trace of the program.
How can achieve this?
You can also use gdb. To debug, compile with g++ and -g at the end of the command and then run your program with gdb (in linux, gdb ./NameOfYourProgram). Then, you type r to run it, and when an error occurs, just type where and you get the stack. You can also set breakpoints and perform steps with gdb to examine the bug further.
How can I redirect execution errors of a c++ executable in bash? I've found that 2> helps while trying identify compilation errors:
g++ example.cpp 2> compErr.txt
But running the executable with that command still sends the errors to stdout:
$ ./a.out 2> e.txt
Floating point exception (core dumped)
Actually, the error "Floating point exception (core dumped)" does not come from the executable but from the shell! The messages from bash won't be suppressed by output redirection but there is a flag to enable/disable these messages.
You can install signal handlers for some of the errors which would cause the program to exit and write something to a suitable destination there. Some signals can't be intercepted and some other are hard to handle. That's the approach you can do from inside your code.
If you want to go further you could fork() your program first thing and have the actual work done in the child process. The parent process would essentially just waitpid() for the child process and use the information in the result structure received to report errors to a file.
I found something that worked in my terminal, here: http://bytes.com/topic/c/answers/822874-runtime-error-stderr-gcc-ubuntu-bash
In summary, a participant explained:
In this particular case, the reason that the string "Floating point exception" is not >redirected is that it is not produced by the process that runs ./{file} or anything that it invokes. Instead,it is being produced by the command-interpreter itself.
You can see this by telling the command interpreter to run another command interpreter, redirecting this sub-interpreter's error output. However, a bit of a >trick is required:
$ bash -c './{file}; true' >out 2>err
$ cat out
$ cat err
bash: line 1: 28106 Floating point exception./test_fail
I am trying to build LLVM on windows, and everytime I do so I get to a certain point and then recieve an error that says "not.exe has stopped working" It pops up on the desktop about 15 times.
I am not sure what is going on, but when I check the error in Visual Studio I receive this:
Error 4 error : Couldn't execute program 'C:/Users/Cyborg/Documents/Developer'The process cannot access the file because it is being used by another process. C:\Users\Joe\Documents\Dev\llvm\test\CUSTOMBUILD check-llvm
I receive this error 5-7 times depending on how fast I click the error that pops up on the desktop. So clearly this issue is happening because of that.
The fault module is: MSVCR100.dll
Does anyone know why this is happening?
I don't know why you're getting the error since I don't build or use LLVM on Windows. Since no one else has chimed in, I'll try to give a hint or two.
"not.exe" (or "not" under Linux) is a little LLVM helper program used when running the lit based regressions tests. It is used to execute a program and return a good exit status if the program fails and a bad exit status if the program doesn't fail.
I'm guessing that "CUSTOMBUILD check-llvm" (what ever that is) is attempting to run the regression tests and your getting your mysterious error as a result whenevr "not" is used.
I hope that helps.
