I've been following Thrift C++ wiki tutorial. and everything works fine with TSimpleServer.
But, when I try to implement TNonblockingServer I'm getting this error :(
undefined reference to `apache::thrift::server::TNonblockingServer::serve()
undefined reference to `apache::thrift::server::TNonblockingServer::~TNonblockingServer()
I think its something related to the header files or the namespaces.
The following headers im using:
#include <thrift/protocol/TBinaryProtocol.h>
#include <thrift/server/TSimpleServer.h>
#include <thrift/transport/TServerSocket.h>
#include <thrift/transport/TBufferTransports.h>
#include <thrift/concurrency/ThreadManager.h>
#include <thrift/concurrency/PosixThreadFactory.h>
#include <thrift/server/TThreadedServer.h>
#include <thrift/server/TNonblockingServer.h>
using namespace ::apache::thrift;
using namespace ::apache::thrift::protocol;
using namespace ::apache::thrift::transport;
using namespace ::apache::thrift::server;
using namespace ::apache::thrift::concurrency;
any idea whats wrong?
I understand that this is really late reply.
It is due to missing libthriftnb library for TNonblockingServer.
while Tsimplesever and TThreadedServer are in libthrift library so it was works with you.

I have a native library for an Android app. When I load the entire C++ project in Android Studio, some errors are thrown by the IDE saying:
cannot resolve namespace std and cannot find any C++ headers.
#include <fstream>
#include <iostream>
#include <map>
using namespace std;
For all of the above code, fstream, iostream, etc is being marked red and shows cannot find. Any workaround to fix the above issue?
I am getting an error saying namespace "bsoncxx::v_noabi::builder::basic" has no member "make_document", I have already added required included as per mentioned in the tutorial.
I am using mongo-cxx-driver-r3.1.1 version.
i have followed example from here
here is what I have tried
#include "maxi.h"
#include <cstdlib>
#include <iostream>
#include <bsoncxx/builder/basic/array.hpp>
#include <bsoncxx/builder/basic/document.hpp>
#include <bsoncxx/builder/basic/kvp.hpp>
#include <mongocxx/client.hpp>
#include <mongocxx/instance.hpp>
using bsoncxx::builder::basic::kvp;
using bsoncxx::builder::basic::make_document;// here is error
using bsoncxx::type;
mongocxx::instance inst{};
mongocxx::client conn{ mongocxx::uri{ "mongodb://localhost:27017" } };
see image here
I have already tested MongoDB driver after compiling and its working perfectly. I need to use make_document option for some reason in order to achieve my goal.
Not sure possible bsoncxx::builder::basic::make_document; option may have been removed or replaced with something else which I don't know.
In the current master branch, document.hpp file contains make_document method.
if I'm not mistaken you are using stable release version.
Take a look here.
Using declaration “not found” in MongoDB c++ driver
I'm using the mongo-cxx-driver-r3.1.1 based on mongo-c-driver-1.6.2.
Using the latest examples provided on github, I managed to find how to connect the database and how to save documents.
I'm struggling to fetch results using a filter following the informations provided in the mongocxx/query.cpp example.
There's a lot of call to a make_document method but I have no class/method/template in the bsoncxx namespace with that name (same problem with make_array).
Heres's the includes, the using directives and using declarations :
#include <bsoncxx/builder/basic/document.hpp>
#include <bsoncxx/builder/basic/array.hpp>
#include <bsoncxx/builder/basic/kvp.hpp>
#include <bsoncxx/types.hpp>
#include <bsoncxx/json.hpp>
#include <bsoncxx/stdx/make_unique.hpp>
#include <bsoncxx/stdx/optional.hpp>
#include <bsoncxx/stdx/string_view.hpp>
#include <mongocxx/instance.hpp>
#include <mongocxx/pool.hpp>
#include <mongocxx/stdx.hpp>
#include <mongocxx/client.hpp>
#include <mongocxx/logger.hpp>
#include <mongocxx/uri.hpp>
#include <mongocxx/exception/exception.hpp>
#include <mongocxx/options/find.hpp>
using namespace mongocxx;
using namespace bsoncxx;
using bsoncxx::builder::basic::document;
using bsoncxx::builder::basic::kvp;
using bsoncxx::builder::basic::sub_document;
using bsoncxx::builder::basic::sub_array;
using bsoncxx::builder::basic::array;
using bsoncxx::types::value;
using mongocxx::result::insert_one;
The using declarations "not found" :
using bsoncxx::builder::basic::make_array;
using bsoncxx::builder::basic::make_document;
Am I missing something obvious ?
Are there more recent examples ?
Your code looks right, as you included all necessary header files needed for make_document and make_array.
You said in your comment, that the document.hpp doesn't contain the make_document and the array.hpp doesn't contain the make_array template.
This is right for the release mongo-cxx-driver-r3.1.1.
In the current master branch the header files exists as you can see if you follow the source links for them: document.hpp and array.hpp. The examples you use are probably for the new master branch as they are also from a current branch from git.
While developing Raspberry Pi library compiled by g++4.9.2 I have met compability issue between boost (1.6.2) and ImageMagick++ API (7.0). When compiling this code:
#include <Magick++.h>
#include <boost/filesystem.hpp>
#include <boost/foreach.hpp>
I got these boost errors:
__assert_fail was not declared in this scope (path_trails.hpp)
...
__assert_fail was not declared in this scope (path.hpp)
...
__assert_fail was not declared in this scope (shared_ptr.hpp)
When deleting #include <Magick++.h> line everything runs fine. Unfortunately I need boost and ImageMagick as well in this source file. How to solve this issue?
A simple workaround is to include Magick++.h after boost.
#include <boost/filesystem.hpp>
#include <boost/foreach.hpp>
#include <Magick++.h>
I don't have a proper explanation for this problem but it seems to come from a clash when using different headers including assert.h (I had the same problem using the assimp library and ImageMagick) but I don't get why the order matters.
Reproducing your case, assert.h is included in:
cassert for boost
MagickCore/pixel-accessor.h for Magick++.h
If someone has an explanation for this problem feel free to edit.
When I am compiling my program
I am getting this error
undefined reference to `std::__default_alloc_template<true, 0>::deallocate(void*, unsigned int)'
It feels that it is not albe to find reference in the standard libraries or something.
Is it some kind of lib conflict.
Basically I am trying to port piece of code which was on GCC 3.1.1 to 4.1.2
As there is compiler change I am facing this issue
Are you linking with other components still on 3.1.1 or even linking with the wrong GNU library?
Did you #include all the appropriate headers for the standard library components you're using?
For example,
#include <cstdlib>
#include <vector>
#include <algorithm>
#include <functional>
#include <map>
#include <set>
Sound to me like you are using some c++ code.
'std' namespace and the 'template'.
Try using g++ to compile your code and if that doesn´t work try to put "using namespace std;" after your include lines.
Can you please provide atleast some few lines from where the error is from?
Btw found this link with the same question asked: Here
Where they suggest installing libstdc++.
