I have an executable file, which I want to convert back to bc/ ll format. Is there a way?

I am new to using C++. I am trying to convert an image to a string (I need to convert an image to a buffer).
So I use the "opencv" library. I try it but it doesn't work. When I execute my program this way:
g++ testpng.cpp -o testpng
This is the error in the terminal:
/usr/local/include/opencv4/opencv2/opencv.hpp:48:10: fatal error: opencv2/opencv_modules.hpp: No such file or directory
48 | #include "opencv2/opencv_modules.hpp"
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.
I need help to solve this error, or a working example to convert an image (.png) to a string, please!!
If all you want is to load an image and then retrieve data from it, use the stb header library. It's simple to use, no binary libraries, only header files required. Simply download it from github and then include the stb_image.h file in your project.
I'm new to dwarf format and trying to generate dwarf info.
I'm using windows.
I used this command gcc -c --debug=dwarf file_name and it is generating file in binary format.
So is this the right way?
is there any efficient way?
also how can I convert this binary file to readable format?
I need to access only function and variable details, So is there a way to only generate this info?
I'm using arm-none-linux-gnueabi-g++ in order to compile a c++ code that will run on an embedded Linux device.
I'm using the arm-none-linux-gnueabi-g++ under windows and get as output the binary file that will run on the Linux machine.
In order to set the embedded device with a new binary, I need to create an archive file (zip) with the binary file and with some more settings files.
till far it all OK.
I need to automate that so that the archive file will be created automatically at name of the version of the binary file.
Currently, we keep the version as just a simple constant std::string variable in the code. We use that string when printing diagnostic, logging, etc.
How can I read that from the version binary file?
Or may other methods to achieve that goal?
I thought may to store it in some constant place in the binary file and read it from there but really don't know how to do that without making the binary corrupted.
You are creating the file automatically, so I assume you are first compiling it and then making an archive with the resulting binary.
You could store the version in a text file, and #include that file in your code:
const std::string version =
#include "version.txt"
;
In the version.txt:
"version string"
And when making the archive, you can easily parse the version from the text file.
Ville is correct.
You're currently doing it backwards!
Your build system should provide the version to the executable, not the other way around. Once this is fixed, your build system can provide the same version to other elements, such as your ZIP filename.
Ideally the version would be generated from version control autonomously, but you could specify it in the build command if really necessary.
It's possible to pull some string from the binary (think nm, if there's a Windows equivalent), but that's really the reverse way to do it.
I start to work with C++ and VTK libraries and I'm trying to build this tutorial: http://www.vtk.org/Wiki/VTK/Examples/Cxx/Medical/GenerateModelsFromLabels
The input argumentn (for me is a NIFTI file) must be in META Format but I don't understand how convert my NIFTI file in this META Format with VTK libraries.
Any ideas? Thank you! :)
You can read the nifti file with vtkNIFTIImageReader instead of vtkMetaImageReader

There's a nice C++ example in the libflac source tarball.
It's also possible to browse it online (single cpp file).
