Title: SFML static linking
Post by: Sander777 on July 11, 2019, 01:12:01 pm

I have such C++ code

#include <iostream>
#include "SFML/Window.hpp"

#define SFML_STATIC

int main() {
        sf::Window window(sf::VideoMode(800, 600), "test");
}
 

And such Makefile

CC                              := g++
DEBUG_FLAGS     := -mwindows
RELEASE_FLAGS   := -s -O3 -w -mwindows

BIN             := bin
SRC             := src
INCLUDE := -Iinclude
LIB             := -Llib

LIBRARIES := -lsfml-window-s -lsfml-system-s -lopengl32 -lwinmm -lgdi32

EXECUTABLE      := main.exe

all: $(SRC)/*
        $(CC) $(DEBUG_FLAGS) $(INCLUDE) $(LIB) $(LIBRARIES) $^ -o $(BIN)/$(EXECUTABLE)

release: $(SRC)/*
        $(CC) $(RELEASE_FLAGS) $(INCLUDE) $(LIB) $(LIBRARIES) $^ -o $(BIN)/$(EXECUTABLE)

clean:
        $(RM) $(BIN)/$(EXECUTABLE)

run:
        ./$(BIN)/$(EXECUTABLE)
 

But I can't compile and I am geting such error

If I'm not mistaken - which I very well may be - SFML_STATIC should be declared before including SFML modules.

It's normal, as far as I'm aware, to define SFML_STATIC outside of the code and in some building properties; this allows dynamic builds with no change to the code - only those properties.

Still error, but this time seems it looks different.

#define SFML_STATIC

#include <iostream>
#include "SFML/Window.hpp"

int main() {
    sf::Window window(sf::VideoMode(800, 600), "test");
}

If I'm adding -DSFML_STATIC to compiler flags it gives me the same error message.

The $^ needs to be before the libraries, otherwise the source file won't know about the libraries.
Always follow the rule of thumb: If X depends on Y, X has to come before Y.
