Hi Melvin,
From the error message it appears you are using version 14.10.25017 headers with MSVC17. Why is this ? Were these part of the MSVC17 distribution ?
c:\program files (x86)\microsoft visual studio\2017\community\vc\tools\msvc\14.10.25017\include

Subject: Re: [Discuss-gnuradio] Global namespace Errors with Complex and xlocNumThe complex and locNum errors stopped once i moved stdafx.h to the very top, thanks for the tip. However, now im getting string errors? Specifically towards xstring and string, Ill provide a few lines of those:
1>c:\program files (x86)\microsoft visual studio\2017\community\vc\tools\msvc\14.10.25017\ include\xstring_insert.h(24): error C2143: syntax error: missing ';' before '{'

I've added <string> and <cstring> but the issue still hasn't been solved and i have no clue on how to proceed. Its a real pain
You mentioned you never build gr with msvc17, what do you use?
Respectfully,
Melvin

Hey :)
Ah, ok, didn't realize that. Looks like some compiler confusion, then. So, I've gotta admit, never tried to build GR with MSVC17, so here's a bit of guesswork:
* Not overly familiar with things under visual studio, but isn't it somehow customary to include stdafx.h as the very first thing?
* Since I don't immediately spot where you're using any of its functions: Why not remove #include <cmath> and see if it helps?
Best regards,
Marcus
PS: please make sure to keep the whole list in your replies – that way, more than one person has a chance to answer!

Hey Marcus,
thanks for the quick reply, the problem is more C++ oriented than GNU. But, im not using those math functions or any in fact explicitely anywhere in the code which leads me to believe the problem is related to the libraries and since you guys understand them more than i do im hoping for some insight on the issue.
Respectfully,
Melvin

______________________________Hi Melvin,
Not 100% sure, it's getting late, but if you use #include cmath, wouldn't it be std::pow instead of pow? I don't really see the connection of your problem to GNU Radio, to be totally honest.
Best regards,
Marcus

Hi there,
I'm coding a program in C++ whose purpose is data logging, in it i'm using GNU radio libraries. In addition, i'm declaring gr hierarchical blocks in the code as they have a connect function that simplifies the complexity of the program.
I'm using Visual studio IDE with visual C compiler to run the program and as i do i get various errors which i have been trying to figure out for days. I've googled similar errors and asked in stackoverflow but i've had no luck.
Ill include some of the lines of errors i'm getting as well as some lines of code(the program is small) to make this email as clear as possible. In the attachment i included a txt file that contains the full code and errors.

gr::uhd::usrp_source::sptr usrp = gr::uhd::usrp_source::make(device_args, stream_args);
......
As for attempted solutions i included the complex and xlocnum but had no luck.Another posible solution was that std:: is said to be undefined behaviour, so i added "using namespace std;"(which is suggested not to do but how else would i declare the strings and vector<float>) and deleted the "std::" in each line that contained it, but again no luck.
If anything is required of me do not hesitate to ask, any sort of help is greatly appreciated.
Ill include the headers im using here also:#include <iostream>
#include "stdafx.h"
#include <cmath>
#include <uhd/usrp_source.h>
#include <filter/firdes.h>
#include <gnuradio/filter/fir_filter_ccf.h>
#include <gnuradio/top_block.h>
#include <gnuradio/blocks/head.h>
