linux下Opencv的简单程序:
编译方法:
1、 g++ test.cpp `pkg-config opencv --libs --cflags opencv` 编译没问题,正确。也能够执行
2、 g++ `pkg-config opencv --libs --cflags opencv` test.cpp 编译错误,不成功。
错误提示:
tmp/ccI1amzW.o: In function `main':
test.cpp:(.text+0x5e): undefined reference to `cv::imread(std::basic_string const&, int)'

请指点。
