I wrote this code:
#include <iostream>
#include <fstream>
#include <sstream>
#include <algorithm>
#include <iterator>
#include <vector>
#include <regex>
using namespace std;
int compile()
{
string linecode;
linecode = "_hello:";
if (std::regex_match (linecode, std::regex("(_)(.*)(:)") ))
{
cout<<"...";
}
else if (std::regex_match (linecode, std::regex("(#)(.*)(:)") ))
{
cout<<"###";
}
return 1;
}
int main(int argc, char** argv)
{
compile();
return 0;
}
And i get this error:
enter image description here
cstring error, probably in regex library.
How i can fix this ?
Thanks in advance.

I have a code that is executable without error messages but it seems like it denies to run the code
I call by the "spawnl" command. This is my code and I receive "error=-1". I tried may different ways to solve the situation but I always receive the "-1" for an answer. I use Dev C++ compiler with 32bit release. My problem is to call the other program, sending the name of the file.

below I've posted my code which is meant to store hits collections in HCE (hit collection of events).
The code compiles successfully but on running the program, the following error is printed to the terminal seven times:
< SiHCollection> is ambiguous.
I have a feeling it is because I am using namespace std although I don't know how to amend the code. Any thoughts?
#include "SiSD.h"
#include "SiHit.h"
#include "G4HCofThisEvent.hh"
#include "G4Step.hh"
#include "G4ThreeVector.hh"
#include "G4SDManager.hh"
#include "G4ios.hh"
#include "G4UnitsTable.hh"
#include <fstream>
#include <iostream>
#include <sstream>
using namespace std;
extern ofstream outfile;
SiSD::SiSD(G4String name)
:G4VSensitiveDetector(name)
{
collectionName.insert("SiHCollection");
}
SiSD::~SiSD(){ }
void SiSD::Initialize(G4HCofThisEvent* HCE)
{
SiHCollection = new SiHitsCollection(SensitiveDetectorName,
collectionName[0]);
static G4int HCID = -1;
if(HCID<0)
{
HCID = G4SDManager::GetSDMpointer()->GetCollectionID(collectionName[0]);
}
HCE->AddHitsCollection(HCID, SiHCollection);
}
G4bool SiSD::ProcessHits(G4Step* aStep, G4TouchableHistory*)
{
if(aStep->GetTrack()->GetTrackID() > 0) {
G4double edep = aStep->GetTotalEnergyDeposit();
if(edep==0) return false;
SiHit* aHit = new SiHit();
aHit->SetEdep(edep);
SiHCollection->insert(aHit);
return true;
} else return false;

I am using Visual Studio 2010, with OpenCV 3.0. I'm trying to load some images from a folder but I am having problems.
Firstly I did not have the file dirent.h, so I downloaded it in order to get the DIR* and "dirent*" structures to access to the files. All seems to be well, but now when I get to the line
string fileName = in_file->d_name;
I have found that I don't access to the name of the file.
Anyone have any thoughts on this?
This is the code:

}
while ((in_file = readdir(FD)))
{
/* On linux/Unix we don't want current and parent directories
* If you're on Windows machine remove this two lines
*/
// if (!strcmp (in_file->d_name, "."))
// continue;
// if (!strcmp (in_file->d_name, ".."))
// continue;
/* Open directory entry file for common operation */
/* TODO : change permissions to meet your need! */
string fileName = in_file->d_name;
string pathFile = imagesPath;
pathFile.append("/");
pathFile.append(fileName);
//pathFile.append(".jpg");
Mat img = imread(pathFile.c_str());
Thanks in advance.
for a much simpler solution, just use cv::glob :
String imagesPath = "Images/*.png"; // it has filters, too !
vector<String> fn;
glob(path, fn, true); // recursive, if you want
for (size_t i=0; i<fn.size(); i++)
{
Mat img = imread(fn[i]);

where i can find an sample code for hypertable or else can any one post an sample for hypertable with c++
If you meant the source code for hypertable
otherwise here is the manual
You can use this HQL tutorial or look at this example

将其和/opt/hypertable/current/include/ThriftBroker/gen-cpp文件夹下的
Client_constants.cpp、Client_types.cpp、ClientService.cpp、Hql_constants.cpp、Hql_types.cpp、HqlService.cpp一起编译
