arm-linux-g++ contours.c cannot find -lml -lhigggui,请指教

gearyman

opencv2.2.0  路径是/opt/EmbedSky/opencv-2.2.0/
arm-none-linux-gnueabi-gcc 4.3.3,路径是/opt/EmbedSky/4.3.3/bin
cmake-gui 0.8.5交叉编译opencv的，路径是/opt/EmbedSky/lib-arm/lib,/opt/EmbedSky/lib-arm/include/opencv，opencv里面包含了几个头文件和opencv2目录，file 测试后都是arm版本的lib
库目录，如下
libopencv_core.so    sharedlibrary
libopencv_ml.so       shraredlibrary
libopencv_calib3d.so sahredlibrary
....
接着，我编译/opt/EmbedSky/opencv-2.2.0/samples/c/contours.c，命令如下
arm-none-linux-gnueabi-g++ controus.c -o contours -I/opt/EmbedSky/lib-arm/include/opencv -L/opt/EmbedSky/lib-arm/lib -lml  -lhigui -lcore -lcalib3d
出现，cannot find -lml ，请高手帮忙，小女子不甚感激
