【问题描述】：

我正在尝试在 openGL 中对立方体进行纹理处理。我正在使用 GLUT 和 Visual C++ 2010。我正在使用流行的图像加载器 SOIL.h，并且我正在使用来自其他用户的代码。该代码旨在将一个 3-D 立方体绘制到屏幕上，并应用纹理。我在 VC++ 的头文件文件夹中包含了 SOIL.h，但每次编译时都会出现此错误：

error LNK2019: unresolved external symbol _SOIL_load_OGL_texture referenced in function "int __cdecl LoadGLTextures(void)"

如果需要，我会提供任何额外信息。

这是我的代码：

#include <stdio.h>
#include <stdlib.h>
#include <glut.h>

#include "SOIL.h"

GLuint texture[6];//6 textures for 6 faces of the cube

GLfloat xRot,yRot,zRot;//control cube's rotation

int LoadGLTextures()

int Status = 0;
char *bmpFile[6]      "BmpFile/1.bmp","BmpFile/2.bmp","BmpFile/3t.bmp","BmpFile/4.bmp","BmpFile/5.bmp","BmpFile/6.bmp";

for (int i = 0;i < 6;++i)
    texture[i] = SOIL_load_OGL_texture(
        bmpFile[i],
        SOIL_LOAD_AUTO,
        SOIL_CREATE_NEW_ID,
        SOIL_FLAG_INVERT_Y);
    printf("texture[%d]: %d\n",i,texture[i]);
    if(texture[i] == 0)
        Status = 0;
    glBindTexture(GL_TEXTURE_2D,texture[i]);
    glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MAG_FILTER,GL_LINEAR);
    glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MIN_FILTER,GL_LINEAR);

【问题讨论】：

库链接不正确

【参考方案1】：

您好像忘记在链接器设置中添加所需的库。

将 libsoil.lib 文件夹路径添加到 Visual Studio 链接器设置。

如果尚未提供库，您可能必须从 windows 源代码构建库。
