header files online database

[arek___]

I would like to run quite old C code which requires file headers as follows:

#include "nrutil.h
#include "nr.h"
#include "general.h"
#include "other.h"
#include "memory.h"
#include "experimental.h"
#include "corrinfo.h"

Is there any good online database where I could download such files from?
Thank you.

I quick internet search for the first one shows it is available from codeforge

headers such as general.h, other.h are likely to be specific to a particular program. I doubt these are available elsewhere.

memory.h is too generic a name to know to which it refers. There is memory.h as part of LLVM - but that's c++ code.

If you have the c code, aren't the headers available as well?

Thank you for your last post, I managed to get the complete code with its original header files from the authors.

Could I ask you to recover that attached C code, it was written about 20years ago in environment I do not know. It produces many errors in MSVC2019. I would prefer to have it running in modern environment, I hope it will not be a huge problem to remove these, I believe, simple errors. The main file is corrinfo.c. If possible, could you pls write a short comments how the errors were removed, I would like to learn how to remove such errors
Thank you very much for your help.

The software we worked at the summer (cmath/gsl) is successfully analysing the data all the time now.

The header files are just that - headers. They don't have the associated source code for the declared functions (ie for the functions declared in nrutil.h). To get this code to compile you either need the code for these functions (eg nrutil.c)- or correct import .lib file(s).

Lots of errors. Many undefined types: What is "vector" in pure C code for example?

[2kaud]

vector is a C++ container. If you have reference to a vector in C code, then you'll need to obtain the definition as it probably won't be the same/have the same interface as the C++ one.

You could probably reverse engineer one from its usage - but that's not a minor thing to do.

Yes, undefined in pure C code as I said/asked.

A question regarding visualisation of matrices in the MSVC2019 debugger.

Post your question directly.

Post your question directly.

Could you pls let me know what you meant by 'Post your question directly'. Thanks.

Very simple: you should ask your questions directly in the forum posts, not in some attachments that have to be downloaded just to read what you meant.
The same is valid for the (not too long) code snippets.

Hi,

I would have a technical question regarding MSVC2019.
I got a code written by someone else and would like, step by step, to follow i.e. to see how every variable is manipulated along the code to understand the mathematical transformations.
Of course, it is possible, in very limited way, to watch the single variables in ‘Locals’, but not matrices.
But, I would like to be able to display e.g. the whole data matrix after each single manipulation e.g. after execution of every ‘for’ loop iteration. Is it possible to have a proper access to processed variables or matrices?

Below is the beginning of the software, line 14 corresponds to function: main()
The software gets input variable ‘const mxArray *prhs[]’
In ‘Locals’ we can only see the pointer to ‘const mxArray *prhs[]’, but cannot see the whole content of it.

Or, later, variable ‘mxbinned’ in line 55 contains matrix [40x8], which I cannot see in ‘Locals’, I can only see pointer to this matrix. And so on for all other manipulated matrices in the code/debugger.

--- file_02.jpg ---

I found online that in the past 'Array Visualizer' from https://marketplace.visualstudio.com...rrayVisualizer
was able to present the variables/matrices, but it was stopped some time ago.
Could you pls advise how to sort this problem out, simply to be able to see matrices or whole variables (of course with reasonable sizes) in e.g. the debugger .

Thank you.
