I am trying to install a specific version of gnuradio (3.7.10.1). To do so I am not using Pybombs, but I try to do it from source (I am following this).
First I've cloned the github repository, then checkout the appropriate version. It worked fine until I've tried to invoke CMake and build GNU Radio:
mkdir build
cd build
cmake ../
make
During the make, after 6% done, I have the following error:

I am not a Linux expert and I am not very familiar to this compiler/library support. I don't really understand where the error comes from and how to correct it.
I use Ubuntu 18.04.
Coud you give me a hand on this please?
Any help would be very appreciated.
Thanks a lot.
/usr/include/c++/7/bits/c++0x_warning.h:32:2: error: #error This file requires compiler and library support for the ISO C++ 2011 standard. This support must be enabled with the -std=c++11 or -std=gnu++11 compiler options.
To resolve the above error you need to compile with -std=c++11 flag. Open CMakeLists.txt, find all occurrences or -std=c++98 and change them to -std=c++11. Then go to the build directory, remove CMakeCache.txt and rebuild
sed -i 's/-std=c++98/-std=c++11/g' CMakeLists.txt
cd build
rm CMakeCache.txt
cmake ..
make
Also as the error is in the cppunit and it's used for testing you can try disabling all tests
cd build
rm CMakeCache.txt
cmake -DENABLE_TESTING=OFF ..
make
I've solved for 2 weeks how to build libcurl project. Finally today I managed it, I followed http://curl.haxx.se/libcurl/c/Using-libcurl-with-SSH-support-in-Visual-Studio-2010.pdf but after I wanted to add libcurl to my own project, it throws lot of LNK errors. So here is code my own project, where I want to add libcurl. It's only for downloading file from url:
#include "stdafx.h"
#include "DlData.h"
#include "curl.h"
//#define CURL_STATICLIB
//#pragma comment(lib, "libcurld")
//#pragma comment(lib, "ws2_32")
//#pragma comment(lib, "Wldap32.lib")
size_t write_data(void *ptr, size_t size, size_t nmemb, FILE *stream)
{
size_t written = fwrite(ptr, size, nmemb, stream);
return written;
};
int _tmain(int argc, _TCHAR* argv[])
{
DlData test;
test.PrintMsg("this is test!");
test.WaitForClick();
//Part for download file
CURL *curl;
ofstream fp;
CURLcode res;
char *url = "http://football-data.co.uk/mmz4281/1415/E0.csv";
char outfilename[FILENAME_MAX] = "C:\\Users\\zdenik\\Documents\\GitProjects\\Predictor\\Files\\";
curl = curl_easy_init();
if (curl)
{
fp.open(outfilename);
curl_easy_setopt(curl, CURLOPT_URL, url);
curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, write_data);
curl_easy_setopt(curl, CURLOPT_WRITEDATA, fp);
res = curl_easy_perform(curl);
/* always cleanup */
curl_easy_cleanup(curl);
fp.close();
}
cin.get();
return 0;
}
I set my project properties properly (C/C++ - General, Preprocessor, Linker - General, Input) and want to build it as application - exe file. So far I everything went well and I was able to create libcurld.lib which I added to linker in my project properties. After I built it, it throws a lot of LNK errors and it looks like there is no lib added. Here is output:

========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========
My question is simple. What could be wrong with my project properties settings or how to set libcurld.lib properly?
I finally done it. I downloaded precompiled version of libcurl for Windows 32bit, but before I compiled code, I noticed there is error in char outfilename[FILENAME_MAX] = "C:\Users\zdenik\Documents\GitProjects\Predictor\Files\" row. It is needed to add name of the file at the end of the path string - C:\Users\zdenik\Documents\GitProjects\Predictor\Files\file.csv e.g. It would not cause compile error but app would crash after it's triggering.
After that code compiled successfully.
I try to install pg module to Node.js using this command: npm install pg
At first I had to install Python. Then PostgreSQL 8.x, then Microsoft Visual C++. But still it I cannot do it. I have errors while compiling:
npm http GET https://registry.npmjs.org/pg

Any ideas? Without this module, I cannot connect to my PostgreSQL database through Node.js.
#include<iostream>
#include<vector>
std::vector<std::string> vector1;
int main() {
vector1.push_back("adadad");
std::vector<std::string> vector2;
vector2.push_back("adadd");
if (vector1==vector2) {
std::cout<<"success";
} else {
vector1.swap(vector2);
vector2.clear();
vector2.push_back("adadd");
if (vector1==vector2) {
std::cout<<"success_swap";
}
}
}
Now this works in g++ but not in visual studio. The operator == doesn't work here and throws compilation error in visual studio 2010(ultimate). The same works if the vector is of a integer type.Am I missing something here ? This is not a linux native thing that they have omitted. Why there is a implementation in gcc but not in vc++ ?
The error message that it shows is:

The error happens because in MSVC, std::string's equality operator (==) is not included by <iostream> or <vector>. You have to include <string> as well.
The key line in the message is; "error C2678: binary '==' : no operator found which takes a left-hand operand of type 'const std::basic_string<_Elem,_Traits,_Ax>' (or there is no acceptable conversion)"
You're probably using a really old compiler.
This works for me in MSVS 2005, which isn't that new itself.
If your compiler is C++03 compliant, it should work:
23.2.4
template <class T, class Allocator>
bool operator == ( const vector<T,Allocator>& x,
const vector<T,Allocator>& y);
This is my method defined in IDL:
[id(3), helpstring("method GetBatteryStatus")]
HRESULT GetBatteryStatus([out,retval] SYSTEM_POWER_STATUS_EX2* batteryStatus);
The SYSTEM_POWER_STATUS_EX2 is a struct defined in winbase.h, and this project is a ATLSmartPhone Project, the winbase.h is from Microsoft's SDK.
When I compile the project the error are :
error MIDL2025 : syntax error : expecting a type specification near "SYSTEM_POWER_STATUS_EX2"
If I add import "winbase.h" to the top of the IDL file, the error will be:
error MIDL2003 : redefinition : size_t; error MIDL2003 : redefinition : _LARGE_INTEGER;.....
Then if I add the typedef in in IDL:
typedef[public,uuid(37DE998A-6787-415a-A191-861C315D1248),helpstring("Power Status")]
struct _SYSTEM_POWER_STATUS_EX2 {
...
...
} SYSTEM_POWER_STATUS_EX2;
The error will be:
error C2011: '_SYSTEM_POWER_STATUS_EX2' : 'struct' type redefinition.
So how can I export the SYSTEM_POWER_STATUS_EX2 struct which was defined in winbase.h with IDL?
You can write the IDL version of the SYSTEM_POWER_STATUS_EX2 in the separate IDL file and import it for MIDL only:
cpp_quote("#if 0")
import "fake.idl";
cpp_quote("#else")
cpp_quote("#include <orginial_header>")
cpp_quote("#endif")
