I am trying to create a simple Fix client-server using QuickFix and I have tried to implement QuickFix.Application interface.
During the building I have faced this problem : "Undefined symbols for architecture x86_64" and despite I have already read all the relative answers to this question and trying everything suggested I have still the above issue.
I am using Netbeans and C++, and this is the error I got
g++ -o dist/Debug/GNU-MacOSX/fix_engine_server build/Debug/GNU-MacOSX/Application.o build/Debug/GNU-MacOSX/main.o -lstdc++
Undefined symbols for architecture x86_64:

Any suggestion ?

I am new to using CLion and am trying to build my first project. I have two source files (main.cpp and Hero.cpp) and a header for Hero.cpp. At the top of Hero.cpp there is a yellow banner that reads "This file does not belong to any project target; code insight features might not work properly." I am pretty sure there are no mistakes with regard to the syntax or logic of the program. However, when I try to run my code, I get:

Could somebody help me figure out this problem? Thanks in advance!
I'm trying to use GRANSAC(Generic RANSAC) from this github repository. https://github.com/drsrinathsridhar/GRANSAC
When I build with cmake, this error happens and I don't know how to solve it.

I am trying to compile and run the spline1d_d example from ALGLIB web page on MACOS using C++ Version 14 and cmake Version 3.14.
(code is here: http://www.alglib.net/translator/man/manual.cpp.html#example_spline1d_d_cubic)
The compiler throws the below error message.
Can please somebody help?
Includes from ALGLIB are being found as expected:

I think your using the wrong architecture. 64 bit or 32 bit.
Another error about linking in c++ is that you didn't add reference path to c++ header files in project settings
I'm having an issue assigning values to an Imf::Rgba struct containing half types as defined by OpenEXR. There appears to be a linker error that concerns the conversion from float to half.

I believe this is a common problem on windows and that OPENEXR_DLL needs to be defined. This does not work however as I am compiling on OS X. I have tried linking to libIlmImf.dylib and libIlmImf.a with the same result. The version of OpenEXR being used is 2.2.0 and installed using Homebrew.
These symbols are defined in half.h that is part of IlmBase.
You should link to libHalf.dylib.
I am getting an error when trying to compile my QT app on Mac.
I followed this tutorial all the code is at the bottom of the page.
When I build the project I get the following:

Anyone seen this before or any suggestions?
Thanks in advance. :)
The linker is telling you exactly what's happening. There are no implementations provided for the methods that are listed, namely for:
DiagramItem::addArrow(Arrow*)
DiagramScene::setItemType(DiagramItem::DiagramType)
DiagramScene::setTextColor(QColor const&)
DiagramScene::setMode(DiagramScene::Mode)
Simply write the implementations of those methods. The example might be incomplete if you were copy-pasting the code from the help page.
