I need to make a stub for some standard library function, but the compiler gets confused about which function I want to call in my code. I thought that putting the stubbed function together with its caller into an anonymous namespace will give higher precedence to the stub, but it didn't.
Result: main.cpp: In function ‘void {anonymous}::test()’: main.cpp:23:47: error: call of overloaded ‘sigaction(int, sigaction*, NULL)’ is ambiguous main.cpp:23:47: note: candidates are: main.cpp:8:5: note: int {anonymous}::sigaction(int, const sigaction*, sigaction*) In file included from main.cpp:4:0: /usr/include/signal.h:266:12: note: int sigaction(int, const sigaction*, sigaction*)
It possible to force the compiler to use my stubbed version of sigaction() and if yes, how to do that? I am not allowed to modify test() function.
#include "tensor.h" int main() { Tensor<2,-2> m = {{1,2},{1,3}}; Tensor<2> v = {1,5}; std::cout<<m*v<<"
[Code] ....
Why do I get an ambiguity and why is not the wanted operator*-overload (the last one in the tensor.h file) not even mentioned as one of the candidates? Is it clear what I want to do? And if so, what can I do to make the call unambiguous?
I get the following error in XCode whenever I try to access the member I created 'randomGen' in a separate class in a different header file. I have made sure to include the header file and have tried to access it through an object.
This is the code I enter when trying to access the method from randomiser.h in main.cpp. It is also an overloaded function with doubles and integers:
RandomG randomiser; randomiser.randomGen(); // 'Call to member function 'randomGen' is ambiguous'
This is the code inside randomiser.h:
#include <string> #include <iostream> using std::string; using std::cout; using std::endl; class RandomG {

This is the error inside xcode: [URL] ....
I have tried seperating the code for the functions in another class (main.cpp) and then running and it seems to works, so I'm not sure why I can't put everything in the .h file and then access it?
I would like it in a seperate file so it doesn't clutter my main. I am writing a game with SDL so that might be confusing and I would like the window to have a random title and other random properties, so it would be easier to use a function.
My load function isnt working. I've tested it and returned it as an int and it worked but when i tried to compile when i changed it to a template i started getting the errors and I'm not sure how to fix it:
all_sort.cpp:41:15: error: no matching function for call to 'load' int *value = load("./integers.txt", size); ^~~~ ./bubble_sort.h:44:4: note: candidate template ignored: couldn't infer template argument 'T' T *load(const char* x, int &size) {
[Code] ....
I'm trying to use my load function to load integers from a file into and array and then return it back.
#include "bubble_sort.h" #include <iostream> #include <cstdlib> #include <string> using namespace std; int main(){ int n, pick = 1, size = 0;

I'm using GCC 4.8.1 and I want to implement a XML parser using TinyXML and port it to AngelScript
Now, it says: reference to 'Column' is ambiguous
I've declared a class called xml_parser and I've added everything of tinyxml as it's public member when I call Column(), and also Row(), it give's this error. what should I do?
Okay so inside my ArcherArmor.cpp, I'm trying to figure out why the map initializer list isn't working, but for some reason I keep getting "Error C2593: 'operator =' is ambiguous". Here is my code:
I also have a class which ArcherArmor is derived from, that has a struct called `Armor`, which I left out for simplicity. The main problem is that error! The only thing I can think of is that im initializing the map wrong.
The compiler keeps on telling me that invalid conversion from wxBitmap* to wxString on the line with the AddTool function, whiles I do not even try to do such an ambiguous typecast.

I am working on my project of gesture recognition using c++ and open cv and i am also designing GUI simultaneously. I am using system namespace for GUI part and cv namespace for gestures.
After compiling i am getting error as Ambiguous symbol String is used.

i am writing this bank accounts program using structures. i haven't implemented the function before that i want to check if the data is being read and printed. When i build and run the program in visual studio it gives me the following error. "No constructor could take the source type, or constructor overload resolution was ambiguous". Now whats wrong in this program?
/* Bank Accounts Program */ #include <iostream> #include <string> #include <fstream> #include <cstdlib>//needed to use system() function using namespace std; const int MAX_NUM = 50; struct Name{
have several linux header files included and when I compile my program I get the below errors..Am I NOT supposed to use some of these headers? Source is below as well.Looking through the headers mentioned in these errors, it's looking like stuff really is defined in multiple places...

I've included <cstddef> into a project of mine in favour of <stddef.h>. When I tried to compile my project, I get 50+ errors stating that types such as "::size_t", "::div_t" and "::abort( )" have not been declared even though <cstddef> includes <stddef.h>.
I've tried searching both the global namespace and the standard namespace, but neither way works. At this moment in time, I don't have any compiler options enabled that may affect the way identifiers are defined, C++11 isn't enabled (which doesn't affect the <cstddef> header anyway), the project is a C++ project, and I've tried using the plain old <stddef.h> header, but the problems still persist.
I'm using GNU's C++ compiler ("__GNUG__" is defined).
I am new to C++ language and I am still learning.I'm doing basic stuff to better understand dynamic memory. I was wondering why I keep getting memory issues.*/
At this stage I will obtain Dimensions A, B & C. But after this before I do the pythagoras equation using the data I want it checked over. I think I've done this here but I'm not sure. I want it to report the message "Invalid Data" if Dimension A is not the longest.

I have to create an Array of type Course and then fill its member dats using various member functions. Those errors are caused by some Constructor defect, which I dont really know what it is.
I am currently just trying to update a record in a SQL database.I can add a record and delete a record just fine but when I go to update I get no errors but it just doesn't update.
Here is what I have and done coding for hours trial and error

I'm currently messing around with geolocation and have this Windows App I'm working on. There is no errors or warnings when I run it, but it does not work. I click my Enable GPS button and nada, nothing, zilch. This isn't a important project or anything just a learning experience for myself.
This is my C# portion if you need me to post the XAML side also I can do that as well.

i use cygwin and i have a program that was returning an error saying "undefined reference" and i figured out that i misspelled a word. how can i search for the misspelling in the input mode, if ive just completed a very large program and dont want to scroll through possibly 300+ lines of input? im not totally out the loop, but i know i can "vim program.cpp" to open the program, but before clicking "i" to actually edit, there must be a way to search a word
