请教，库文件缺失问题！

[Eagle_China89]

UBUNTU12.04 请教到底是那个目录下缺少来文件，谢谢！
交叉编译环境：

命令：arm-linux-gcc -lpthread -lrt cam2.cpp -o cam `pkg-config --libs --cflags opencv`

错误：

你这是opencv的库一个都没有？ 编译的时候又加？ pkg-config --libs --cflags opencv 这个的输出是啥？ 是编译需要的么？ 这里提示的就是这个命令需要的那些应该都没找到... 你手动看下都在哪儿呢 自己加个-L目录 试试

[Eagle_China89]

库文件是存在的，本来是自己建的文件夹，问题已经解决了 反正提示的意思是缺少了：/mydrive/arm-linux-gcc/usr/local/arm/4.3.2/bin/../lib/gcc/arm-none-linux-gnueabi/4.3.2/../../../../arm-none-linux-gnueabi/bin/ld: warning: ../../lib/libopencv_core.so 所以我就在讲所有的库文件拷贝到来/mydrive/arm-linux-gcc/usr/local/arm/4.3.2/bin/../lib/gcc/arm-none-linux-gnueabi/4.3.2/../../../../arm-none-linux-gnueabi/bin/../../lib/ 这个目录 然后在编译也就没有错误了，但是在ARM 板上打不开摄像头，运行程序没有语法错误，同样也加载不了图片，也就是说cvLoadImage()和cvCaptureFromeCam()返回值始终为NULL，我查资料说highgui移植不好，你要是用过的化，你是怎么进行图像处理的？谢谢回答
