mingw 和 eclipse 工作正常。我尝试设置 OpenCV 并构建我的项目，但出现以下错误。我没有任何线索来解决这个问题。我用谷歌搜索但没有运气。

【问题讨论】：

我终于修好了。添加所有没有文件扩展名的库。无需编写 libopencv_core2410.dll。只是文件名很好“libopencv_core2410”我还在thinkingweb.co/…记录了所有配置步骤@

【解决方案1】：

为什么您的 -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（不带扩展名）属于 -l... 规范.

另外请注意，gcc 通常会在您指定的名称中添加“lib”前缀和“.a”、“.lib”或“.dll”后缀，甚至是 .dll.a 后缀-l...;有关 MinGW 编译器/链接器将搜索的名称的确切序列的详细信息，请参阅 https://sourceware.org/binutils/docs/ld/WIN32.html#WIN32 的标题直接链接到 dll。
