No I was using wrong version of MinGW probably.
I made it work on CMake using the template you linked, thank you !

General / Trying to compile an SFML test

« on: July 18, 2023, 08:36:03 pm »

Hey,

I trying out SFML, but I got a problem at compilation, probably at linking.

I tried the example that's here: https://www.sfml-dev.org/tutorials/2.6/start-linux.php

I'm on Windows 10 but i'm using make and mingw.

Here is my makefile:

cpp_flags := -Wall -W -std=c++20
sfml_path := C:\SFML-2.6.0
sfml_include := $(sfml_path)\include
sfml_lib := $(sfml_path)\lib
sfml_modules := -lsfml-graphics-s -lsfml-window-s -lsfml-system-s -lopengl32 -lwinmm -lgdi32

test.exe: bin/test.o
   g++ bin/test.o -o test.exe -L$(sfml_lib) $(sfml_modules) $(cpp_flags)

bin/test.o: src/test.cpp
   g++ -c src/test.cpp -o bin/test.o -DSFML_STATIC -I$(sfml_include)

These are some of the errors I get:

ld.lld: error: undefined symbol: sf::String::String(char const*, std::__1::locale const&)
>>> referenced by bin/test.o:(main)

ld.lld: error: undefined symbol: std::basic_ostream<char, std::char_traits<char>>& std::__ostream_insert<char, std::char_traits<char>>(std::basic_ostream<char, std::char_traits<char>>&, char const*, long long)

General / Relocation against in read only section ERROR when trying to load font

« on: September 26, 2020, 12:34:23 am »

Hej !

I'm just working on a new project in SFML on Archlinux and everything went well, until I tried to load a Font. I don't really understanf why i get that error.

HW_Ressource.h

#ifndef HW_RESSOURCES_H
#define HW_RESSOURCES_H

#include <SFML/Graphics.hpp>

class HW_Ressources
{
   private:
      HW_Ressources();
      static sf::Font font_cantarell;
   
   public:
      static void load();
      static const sf::Font get_font_cantarell();
};

#endif

HW_Ressources.cpp

#include "HW_Ressources.h"

void HW_Ressources::load()
{
   sf::Font font;
   
   if(!font.loadFromFile("Cantarell-Regular.otf"))
      exit(EXIT_FAILURE);
   else HW_Ressources::font_cantarell = sf::Font(font);
}

const sf::Font HW_Ressources::get_font_cantarell()
{
   return HW_Ressources::font_cantarell;
}
