MingW 静态库链接 - SFML 2.1 [英] MingW static library linking - SFML 2.1

问题描述

我正在尝试让 SFML 2.1 与 MingW 一起工作，但它导致了问题.

i'm trying to get SFML 2.1 to work with MingW, but it's causing problems.

我在 MingW 编译器中的编译行是:

my compile line in the MingW compiler is:

g++ -ID:\SFML-2.1\include -LD:\SFML-2.1\lib main.cpp -lsfml-graphics -lsfml-window -lsfml-system

我正在尝试链接 .a 文件(这是否意味着我应该在编译行中添加一些东西?).

i'm trying to link .a files (does this mean that i should add soemthing tot eh compile line?).

代码如下:

#include <SFML/Graphics.hpp>

int main()
{
// create the window
sf::RenderWindow window(sf::VideoMode(800, 600), "My window");

// run the program as long as the window is open
while (window.isOpen())
{
    // check all the window's events that were triggered since the last iteration of      the loop
    sf::Event event;
    while (window.pollEvent(event))
    {
        // "close requested" event: we close the window
        if (event.type == sf::Event::Closed)
            window.close();
    }

    // clear the window with black color
    window.clear(sf::Color::White);

    // draw everything here...
    // window.draw(...);

    // end the current frame
    window.display();
}

return 0;
}

当我尝试编译时出现以下错误:

when i try to compile i get these errors:

我做错了什么?错误表示未定义的引用，这意味着找不到某些东西(库?).

what am i doing wrong? the errors say undefined reference, which means that there is something (a library?) that is can't find.

SFML 2.1 包附带调试和发布库 (libsfml--s-d)，这与它有关吗?

The SFML 2.1 package came with both debug and release libraries (libsfml--s-d) does this have something to do with it?

推荐答案

常见问题:

1. 添加-DSFML_STATIC预处理器标志，

使用以 -s 为后缀的库文件:-lsfml-graphics-s 而不是 -lsfml-graphics，

Use the library files suffixed with -s: -lsfml-graphics-s instead of -lsfml-graphics,

添加所有需要的静态库:-lopengl32 -lwinmm -lgdi32 是使用图形、窗口和系统模块时的最低要求.

Add every needed static library: -lopengl32 -lwinmm -lgdi32 is a minimum when using the Graphics, Window and System modules.

一个简单的 Makefile 看起来像这样:

A simple Makefile would looks like this:

EXE := static.exe
SRC := $(wildcard *.cpp)
OBJ := $(SRC:.cpp=.o)
DEP := $(OBJ:.o=.d)

CPPFLAGS := -Ipath/to/SFML/include -MMD -MP -DSFML_STATIC
CXXFLAGS := -std=c++11 -Wall -W -pedantic
LDFLAGS  := -Lpath/to/SFML/lib
LDLIBS   := -lsfml-graphics-s -lsfml-window-s -lsfml-system-s
LDLIBS   += -lopengl32 -lwinmm -lgdi32

.PHONY: all clean

all: $(EXE)

$(EXE): $(OBJ)
    $(CXX) $(LDFLAGS) $^ $(LDLIBS) -o $@

clean:
    $(RM) $(EXE) $(OBJ) $(DEP)

ifeq "$(MAKECMDGOALS)" ""
-include $(DEP)
endif

要移除控制台，请将 -mwindows 链接器标志添加到 LDFLAGS.

To remove the console, add the -mwindows linker flag to LDFLAGS.
