I have built a static opencv library using cmake, and after that I want to invoke the static opencv library for my application. However, it seems that the application program cannot link the static opencv library, and it gives me the following warnings:
ld: warning: ignoring file /usr/local/lib/libopencv_core.a, file was built for archive which is not the architecture being linked (i386): /usr/local/lib/libopencv_core.a

It seems to me that the application program is trying to invoke the dynamic opencv library, and a simple application program that just invokes cv::Mat test will give me the following errors:
Undefined symbols for architecture i386:
"cv::Mat::deallocate()", referenced from:
cv::Mat::release() in main.o
"cv::fastFree(void*)", referenced from:
cv::Mat::~Mat() in main.o
