使用MinGW未定义对DevIL函数的引用

我在C ++连接，静态和dynamic，.lib和.a等方面都不是很有经验。

注意下面我有-l所有的DevIL库（DevIL，ILU，ILUT）。 至于库文件，我把DLL的System32和SysWOW64和MinGW lib中的.libs。 Eclipse项目的“当前工具链”确实是MinGW GCC。 该项目只有1个源文件，facecube.cpp（具有main（））。 我错过了什么？

包括：

#include "Angel.h" #include <ILconfig.h> #include <ILilut_config.h> #include <ILil.h> #include <ILilu.h> #include <ILilut.h> #include <iostream> using namespace std;

编译器输出：

将BMP加载到OpenGL纹理切换红色和蓝色的颜色。 （C ++ /视窗）

从上面忽略的编译指示警告的代码（似乎与我无关）：

333 #pragma warning(push) 334 #pragma warning(disable : 4115) // disables 'named type deFinition in parentheses' warning ... 356 #pragma warning(pop)

看起来你正在混合32位和64位模块。 具体来说，当我编译一个32位程序，但链接到64位DevIL库时，我可以得到同样的问题。

确保你已经下载并链接到Devil-SDK-x86-1.7.8 SDK（ http://downloads.sourceforge.net/project/openil/DevIL%20Windows%20SDK/1.7.8/DevIL-SDK- x86-1.7.8.zip ）。 您还应该确保使用相应SDK的头文件，尽管这可能不那么重要。
