I've tried to make the code as simple as possible and I'm still getting
undefined reference to `boost::log::v2_mt_posix:: . . . etc.
This is driving me crazy, so I'm posting my code:

It looks like you installed a static version of boost.
The boost::log::v2_mt_posix namespace is implemented in dynamically built versions of boost (see this link). Your application will attempt to link against symbols from this namespace if you define the BOOST_LOG_DYN_LINK macro during compilation.
If you have the statically built version of Boost.Log installed to /usr/local, try removing the -DBOOST_LOG_DYN_LINK from your ${CMAKE_CXX_FLAGS} line, regenerate your build directory and attempt the build again. (Side note: typically you will add compiler definitions with the add_definitions() command, see this link)
Or, reinstall a dynamic version of boost.

I am trying to compile a simple program to read a HDF5 file. The code compiles correctly with h5c++. However I need a cmakelists.txt for the same
readdata.cpp
#include <iostream>
#include "H5Cpp.h"
#ifndef H5_NO_NAMESPACE
using namespace H5;
#endif
const H5std_string FILE_NAME( "testfile.h5" );
int main (void)
{
H5File openFile( FILE_NAME, H5F_ACC_RDONLY );
}
I tried a cmakelists for it but it didnt work. It gave "not defined errors"
readdata.cpp:(.text+0x1d): undefined reference to `H5::FileAccPropList::DEFAULT'
readdata.cpp:(.text+0x24): undefined reference to `H5::FileCreatPropList::DEFAULT'

cmake_minimum_required(VERSION 3.1.0)

find_package(HDF5 REQUIRED)
include_directories(${HDF5_INCLUDE_DIRS})
add_executable( readdata readdata.cpp )
target_link_libraries( readdata ${HDF5_CXX_LIBRARIES} ${HDF5_LIBRARIES})
If i put the HDF5_CXX_LIBRARIES and HDF5_LIBRARIES manually the it works.
target_link_libraries( readdata libhdf5.so libhdf5_cpp.so)
So it is not able to read $HDF5_CXX_LIBRARIES and $HDF5_LIBRARIES.How can I fix this?
The code you attempt to compile depends on the HDF5 C++ bindings, which are not searched for by CMake's HDF5 module by default. Explicitly add the binding to the find_package command:
find_package(HDF5 REQUIRED COMPONENTS C CXX)
I've built Boost 1.59 for MinGW 4.9.2 32bit as follows:
bootstrap.bat mingw
b2 --prefix=%USERPROFILE%\Code\Libraries\boost toolset=gcc install (these are static libraries)
When trying to compile:
#include <iostream>
#include <boost/asio.hpp>
#include <boost/date_time/posix_time/posix_time.hpp>
using namespace std;
int main()
{
boost::asio::io_service io;
boost::asio::deadline_timer t(io, boost::posix_time::seconds(5));
t.wait();
cout << "Hello World!" << endl;
return 0;
}
With:
g++ -o test -L %USERPROFILE%\Code\Libraries\boost\lib -l boost_system-mgw49-mt-1_59 -I %USERPROFILE%\Code\Libraries\boost\include\boost-1_59 main.cpp
I get this error:

I'm getting this same error across 2 computers. Any help is appreciated!
It's a linker error. You need to link to the Boost System library.
Do this
g++ -o test -L %USERPROFILE%\Code\Libraries\boost\lib -lboost_system -I %USERPROFILE%\Code\Libraries\boost\include\boost-1_59 main.cpp
I'm trying to run this code using c++11 std::thread and the SFML library for networking, however I just cant get it to build. I'm pretty sure it has something to do with how I'm setting up the compiler, but I don't know... How can I get this to work? I've been messing about trying to get this to work, going through tutorials and such for hours now, so I have turned to Stack Overflow for answers. I'm using the code::blocks IDE and the x32-4.8.1-posix-dwarf-rev5 compiler on a windows7 64-bit machine.
#include <iostream>
#include <thread>
#include <string>
#include <SFML/System.hpp>
#include <SFML/Network.hpp>
using namespace std;
void doNetwork() {
cout << "Starting..." << endl;
sf::TcpListener listener;
listener.listen(88);
// Wait for a connection
sf::TcpSocket socket;
listener.accept(socket);
cout << "New client connected: " << socket.getRemoteAddress() << endl;
// Receive a message from the client
char buffer[1024];
size_t received = 0;
socket.receive(buffer, sizeof(buffer), received);
cout << "The client said: " << buffer << endl;
// Send an answer
string message = "Welcome, client";
socket.send(message.c_str(), message.size() + 1);
}
int main()
{
thread task(doNetwork);
task.join();
return 0;
}

I had a simular problem and how i solved this on a Linux system was: Project / build options
Go to linker settings tab.
there i added: sfml-network
Done.
Hope it helps

i was thinking trhat my cmakeLsits.txt was not complete, there is an especial setup that it has to be done??
thx in advance
I am pretty sure that target_link_libraries() macro accepts a target as its first parameter:
target_link_libraries(<target> [item1 [item2 [...]]]
[[debug|optimized|general] <item>] ...)
And you have forgot to specify it. So instead of target_link_libraries(${XercesLib}), try target_link_libraries(${PROJECT_NAME} ${XercesLib}).
Hopefully, that solves it.
I am just trying to make a vector, but it gives me a huge error and I am following a working example from my other project. The code:
#include <stdio.h>
#include <stdlib.h>
#include <vector>
using namespace std;
struct organism {
bool One;
bool Two;
};
std::vector<organism> organisms;
int main() {
printf("Content-type: text/html\n\n");
printf("TEST");
printf(getenv("QUERY_STRING"));
return 0;
}
The error:

I can compile it if I comment out std::vector<organism> organisms; but I have no clue what's wrong with that line. It's exactly the same in my other project, which compiles fine.
You need to compile with g++.exe instead of gcc.exe so that it will know it needs to link with the C++ library.
