linker-errors

This question is very much related to: A) How to separate CUDA code into multiple files B) Link error LNK2005 when trying to compile several CUDA files together Following advice from here: https://meta.stackexchange.com/questions/42343/same-question-but-not-quite and here https://meta.stackexchange.com/questions/8910/asking-a-similar-but-not-the-same-question I am asking a very similar question but I want to be absolutely clear about where is the difference between my question and the questions linked above. I was getting the linker errors from the title when including a header file, which

In Xcode 8, a Swift project of mine works in Debug mode but fails to link in Release mode: Undefined symbols for architecture x86_64: "Swift.UnsafeMutableBufferPointer.(subscript.materializeForSet : (Swift.Int) -> A).(closure #1)" I can fix the error by changing this line: let nextPeriod = currentSchedule.periods.filter({ $0.startDate > now }).sorted(by: { $0.startDate < $1.startDate }).first to: let nextPeriod = currentSchedule.periods.filter({ $0.startDate > now }).first but that obviously alters the behavior of my app. Luckily, I can also fix the error by adding the following line to almost

I am facing a linker error when running my source code, I have attached a screenshot also. I am new in iOS development and so I am not able to get the error. Any help would be much appreciated. Please check https://testflightapp.com/sdk/ios/doc/ A library was not found, that testflight needs. Include that framework (lib) and you are done. Xcode has a bug in which it will double-escape quotes in a path. Note how the error on the screen you captured has ' \" ' and such in it. These are in error. Correct it so it looks like a path, instead. I note also that it appears that your project path has

I have this code /////////////////////////////////////Gnome.cpp file #include "Living.h" class Gnome:public Living{ private: public: Gnome(); void drawObjects(); }; Gnome::Gnome() { spriteImg = new Sprite("graphics/gnome.bmp"); //<-------------this is where it says there is the error loaded = true; } ///////////////////////////////////Living.h file #include <iostream> #include "Sprite.h" using namespace std; class Sprite; class Living{ protected: int x,y; static Sprite *spriteImg; //= NULL; bool loaded; void reset(); public: Living(); ~Living(); int getX(); void setX(int _x); int getY(); void

I have been following the RestKit installation instructions but I now have an error when I try to build the app. This is for ios, iPad specific.

This question already has an answer here: What is an undefined reference/unresolved external symbol error and how do I fix it? 32 answers I am trying to build a C++ program and keep on getting LNK2019 link errors whenever I try defining a new function and building it. I resolved few of them till now, but spend a lot of time to understand the error in detail. Errors I am getting now are as per below: Error 22 error LNK2019: unresolved external symbol "public: __thiscall xmlElements::operator class std::basic_string,class std::allocator >(void)" (??BxmlElements@@QAE?AV?$basic_string@DU?$char

I've downloaded and compiled: http://leenissen.dk/fann/wp/ cmake version 2.8.11.2 gcc (Ubuntu/Linaro 4.8.1-10ubuntu8) 4.8.1 Command used to compile: cmake -D CMAKE_INSTALL_PREFIX:PATH=/usr .

I am using OCMock 3.0.2, which I've installed through cocoapods for my test target: platform :ios, '7.0' xcodeproj 'myProject.xcodeproj' target :myTestTarget do pod 'OCMock', '~> 3.0.2' end link_with "myTestTarget" In my test file (myTest.mm), I've included OCMock and want to try out the new verify-in-place strategy, like so: - (void) test_myTest { MyObject *obj = [MyObject new]; id robotMock = OCMPartialMock(obj); [obj testMethod]; // some asserts OCMVerify([obj _internalMethodToBeCalled]); } So far seems normal. However, when I tried to run this specific test case, I am getting linker error:
