我正在尝试用 MinGW (gcc/g++ 4.7.2)、Windows 7、Eclipse CDT (Kepler) 编译使用 asmlibrary (by Yao Wei) 的代码，但没有成功。我可以使用 MVSC 编译相同的库、Windows 端口（asmlibrary.dll），并且作者还发布了三个文件（cygasmlibrary-4.dll、libasmlibrary.a、libasmlibrary.dll.a），它们应该可以与 gcc 一起使用。当我尝试编译使用 asmlibrary 的代码时，出现此错误：

我问了作者这个问题，他回复我如下：
只是链接像 libasmlibrary.a 不是 -lasmlibrary
我不明白。即使我从命令行尝试，g++ 也不会接受：
C:\Users\Nenad\eclipseCDT\opencv2cookbook\AsmLibrarySDK_FIT\Debug>g++ "-LC:\\OpenCV246MinGW\\x86\\lib" "-LC:\\asmlibraryFaceXpress" -o AsmLibrarySDK_FIT.exe vjfacedetect.o video_camera.o demo_fit.o -l

ee246 -lopencv_objdetect246 -lopencv_photo246 -lopencv_stitching246 -lopencv_video246 -lopencv_videostab246 libasmlibrary.a
（错误与帖子顶部相同）如果我尝试放入 -libasmlibrary.a （当然）我得到：
c:/mingw/bin/../lib/gcc/mingw32/4.7.2/../../../../mingw32/bin/ld.exe: cannot find -llibasmlibrary.a
libasmlibrary gives me g++: error: libasmlibrary: No such file or directory
and so on...
据我所知，链接这个库的唯一正确方法是使用 -lasmlibrary 但它会产生顶部提到的错误。
顺便说一句，即使我根本不包含那个库，我还是得到了这个错误。
然后我又问了作者，他回复我：
像这样的代码 g++ ac -o test libasmlibrary.a -lopencv_library
即使我这样做（或者至少我认为我理解他），它也会产生相同的结果。当然，我什至将（cygasmlibrary-4.dll、libasmlibrary.a、libasmlibrary.dll.a）复制到调试目录中。

Eclipse本身的设置如下：
可能这是一个新手问题，但我完全坚持这一点。我应该怎么做才能让它编译？
