linker-errors

After updating my POD install, Xcode sprouted a new issue: blackops Make sure you open the .xcworkspace file rather than the project file ( .xcodeproj ) when working with pods. That should solve the issue with linking. Some times you need just clean build. It helped me. To clean build go Product -> Clean There are several cases that cause this issue. At the moment, this question has no any accepted answer and also I found another solution for the same issue, I am posting my answer/experience here. In you application, go to Target -> Build Settings, then you will find following attributes.

Error LNK1104 cannot open file ';.obj' project1 D:\project1\source\project1\project1\LINK 1 I'm using visual studio 2015 and openframeworks, I'm fairly new to the c++ language. I couldn't find a line of code which refers to this file. Has anyone had a similar error or does know any tips to find the cause of this error? The build-process has two main step: compile link In the compiling stage the obj files are built from the source file. In the linking step these obj files are "concatenated" resolving unresolved references and builds the final output (static/dynamic library or an executable).

Once I installed Ubuntu 11.10, strange error appears. I want to use GD with my C program, so I installed package "libgd2-xpm-dev". Everything was installed - files gd.h and libgd.a are in "/usr/include" and in "/usr/lib". So, I've tried to compile simple program with GD. #include <stdio.h> #include <gd.h> int main() { gdImagePtr im, im_clear; int black, white; FILE *out1; im = gdImageCreate(100, 100); im_clear = gdImageCreate(100, 100); white = gdImageColorAllocate(im, 255, 255, 255); black = gdImageColorAllocate(im, 0, 0, 0); return 0; } $ gcc -lgd gd.c /tmp/cc6LReuX.o: In function `main':

Sorry to bother anyone with this question, but I've been researching this for hours, with no resolution yet: I am porting a rather massive application to the 10.0 CRT (compiler) in Visual Studio 2010. The app is managed C++/CLI that uses /clr. Most of the code is native (95%), with a few managed portions here and there in it. So my job is to make the switch in the .vcxproj to target the newer 10.0 CRT (i.e. compiler). We were previously using v90, or using the VC compiler that came with VS 2008 SP1. Ok, so breaking changes? Seems like a bunch actually. I fixed a few iterator issues dealing

why if we have pure virtual assignment operator in a base class, then we implement that operator on the derived class, it give linker error on the base class? currently I only have the following explanation on http://support.microsoft.com/kb/130486 , it said that the behavior is by design since normal inheritance rules does not apply . it is not clear for me, why is it generate linker error by design? can someone give me more clear explanation about this? edit: added my simplified code of which the error occured: class __declspec(dllexport) BaseClass { public: int memberA; virtual BaseClass&

When I attempt compiling the following code I get a linker error: Undefined symbols for architecture x86_64: "Foo()", referenced from: _main in main.o using LLVM 4.2. This behavior only occurs when the function is marked constexpr . The program compiles and links correctly when the function is marked const . Why does declaring the function constexpr cause a linker error? (I realize that writing the function this way doesn't give the benefit of compile-time computation; at this point I am curious why the function fails to link.) main.cpp #include <iostream> #include "test.hpp" int main() { int
