mingw和eclipse工作正常。我尝试设置OpenCV并构建我的项目，但收到以下错误。我没有任何线索来解决这个问题..我谷歌但没有运气。

答案 0 :(得分：0)
为什么你的-l ...引用包含DLL文件的完整路径名？如果路径不是编译器自动搜索的路径，则目录路径属于-L ...规范，只有DLL文件的基本名称（没有扩展名）属于-l ..规范。
另请注意，gcc通常会添加一个＆＃39; lib＆＃39;前缀，＆＃39; .a＆＃39;，＆＃39; .lib＆＃39;，或＆＃39; .dll＆＃39;后缀，甚至是.dll.a后缀，指定您使用-l ...指定的名称;有关MinGW编译器/链接器将搜索的名称的确切顺序的详细信息，请参阅{{3>}处的标题直接链接到dll 。
