我正在使用 sfml 2.0 创建一个文本类，当我尝试构建时遇到链接器错误。这是错误：
Error 1 error LNK2019: unresolved external symbol "__declspec(dllimport) public: static class sf::Font const & __cdecl sf::Font::getDefaultFont(void)" (__imp_?getDefaultFont@Font@sf@@SAAEBV12@XZ) referenced in function "public: void __cdecl Text::create(class sf::RenderWindow &,char *,char *,float,float,unsigned int,enum style,int,int,int)" (?create@Text@@QEAAXAEAVRenderWindow@sf@@PEAD1MMIW4style@@HHH@Z) C:\Facepunch Pacman Project\Faceman\Text.obj Faceman
这是text.h：
#ifndef TE_TEXT
#define TE_TEXT
#include <SFML/Window.hpp>
#include <SFML/Graphics.hpp>
enum style { bold, italic, underlined };
class Text {
public:
void create(sf::RenderWindow &window,
char* string,
char* fontpath,
float positionx,
float positiony,
unsigned int size,
style textstyle,
int red,
int green,
int blue);
void setString();
void setFont();
void setPosition();
void setSize();
void setColor(int red, int green, int blue);
Text operator==(Text t);
Text operator!=(Text t);
sf::Rect<int> textrect;
void setRect();
private:
char* getString();
char* getFont();
float getPosition();
unsigned int getSize();
sf::Vector3i getColor();
sf::IntRect getRect();
};
#endif
文本.cpp（未完成）：
#include <Source/Text/Text.h>
void Text::create(sf::RenderWindow &window, char* string, char* fontpath, float positionx, float positiony, unsigned int size,
style textstyle, int red, int green, int blue) {
sf::Font font;
font.loadFromFile(fontpath);
sf::Text text(string);
text.setFont(font);
text.setCharacterSize(size);
text.setPosition(positionx, positiony);
sf::Color color(red, green, blue);
text.setColor(color);
switch (textstyle)
{
case bold:
{
text.setStyle(sf::Text::Bold);
break;
}
case italic:
{
text.setStyle(sf::Text::Italic);
break;
}
case underlined:
{
text.setStyle(sf::Text::Underlined);
break;
}
}
window.draw(text);
}
显示主菜单功能（这不是新的，我之前一直在使用它，没有任何问题）
Menu::MenuResult Menu::showMMenu(sf::RenderWindow &window) {
sf::Texture texture;
texture.loadFromFile("Source/Images/MenuBG.png");
sf::Sprite MMenuSprite;
MMenuSprite.setTexture(texture);
Text playText;
MenuItem playButton;
playButton.buttonrect.top = 283;
playButton.buttonrect.height = 130;
playButton.buttonrect.left = 0;
playButton.buttonrect.width = WINDOW_WIDTH;
playButton.action = Play;
MenuItem optionsButton;
optionsButton.buttonrect.top = 414;
optionsButton.buttonrect.height = 130;
optionsButton.buttonrect.left = 0;
optionsButton.buttonrect.width = WINDOW_WIDTH;
optionsButton.action = Options;
MenuItem exitButton;
exitButton.buttonrect.top = 549;
exitButton.buttonrect.height = 130;
exitButton.buttonrect.left = 0;
exitButton.buttonrect.width = WINDOW_WIDTH;
exitButton.action = Exit;
menuItems.push_back(playButton);
menuItems.push_back(optionsButton);
menuItems.push_back(exitButton);
window.draw(MMenuSprite);
playText.create(window, "start", "Source/Text/Fonts/BOOKOS.ttf", 514, 352, 65, bold, 0, 0, 0);
window.display();
return getMenuResponse(window);
}
我可能没有正确获取字体文件路径，因为 getDefaultFont 是在未指定字体时。
