A default macOS installation will include something that pretends to be gcc but that’s just a legacy concern so that portable programs will properly detect a compiler when you do a source install with the usual ./configure && make &&…
It sounds like you’re saying you’re printing numbers to stdout and they’re going off the screen. Since you’re using C++ you can replace cout in your output instructions with an ofstream (output file stream) like so: #include <fstream> // ……
Here is one issue: void WaveTableManager::insert(WaveTable * WT,int position) { if (wtvector.size()<=position) wtvector.resize(position); wtvector[position]=WT; // < — Out of bounds access } When you call resize(), the upper bound is vector::size()-1. Since position is the new size of the vector,…
For starters, you should remove #include “Car.h” from Color.h. It creates an unnecessary circular include, and the compiler hits Car(Color a) before it knows that Color is a class. You also need to include the header <string> to output a…
Introduction This question is related to a common error in C++ programming, which is the “expected ‘)’ before object. class does not name a type” error. This error occurs when the programmer attempts to use a class name as a…
The safer way to implement this that doesn’t rely on knowing the internal layout of std::chrono::duration would be to copy to an integer then pass the integer to the duration: std::array<unsigned char, 6> myArray = {123, 123, 112, 0, 15};…
You’re the one running gcc (or g++). It’s a compiler, used by developers. End-user systems may not have any version of gcc. It’s glibc and libstdc++ you need to worry about. But in general, Linux does not aim for binary…
Well I solved the problem i was installing wrong SDL2 libraries: used these: sudo apt-get install libsdl2-dev sudo apt-get install libsdl2-image-dev sudo apt-get install libsdl2-ttf-dev 1 solved SDL2 Exporting to linux
You misspelled defined: #if definied(_WIN32) || definied(_WIN64) || definied(__WIN32__) #elif definied(__linux) || definied(__linux__) || definied(linux) should be: #if defined(_WIN32) || defined(_WIN64) || defined(__WIN32__) #elif defined(__linux) || defined(__linux__) || defined(linux) solved missing binary operator before token “(”
It’ll generate a file “a.out” which you can execute as: . Alternatively you can specify the name for your executable using -o: g++ yourfile.cpp -o myexe 3 solved running a C++ program in Fedora Linux
Do not mix declaration with definition/instantiation in a .h file. Your are instantiating g_font, g_window and g_renderer in isolation.h file. The correct is instantiating only once, usually, in a .cpp To solve your problem, change isolation.h to declare those variables…
The source is in hw.cpp, which obviously is using some kind of argument parsing to look for ‘debug’. For example: #include <stdio.h> #include <string.h> int main(int argc, char *argv[]) { if (argc > 1 && strcmp(argv[1], “debug”) == 0) printf(“Hello…
#include <api.h> is the way you include a system header. (That is, the header for a library installed on your system.) It does not search in the directory of the source file or in directories specified in -I command line…
There are versions of g++ (and versions of Visual C++ as well for that matter) for which on some platforms sizeof(bool) is not equal to 1. So no, you can’t assume that it will be the same on g++ and…
It seems that you don’t have a main function defined. 0 solved Compilation on Linux – In function ‘_start’: (.text+0x20): undefined reference to ‘main’ [closed]
