最近,我将 opencv 构建为静态库(通过使用 BUILD_SHARED_LIBS=OFF),而动态库已经存在,但位于不同的位置。当我构建可能的程序时,我遇到了很多错误。我正在使用命令行编译代码,如下所示。
g++ -static -I$(OpenCV_Static_Build)/include/opencv -L$(OpenCV_Static_Build)/lib/ -g -o binary main.cpp -lopencv_core -lopencv_imgproc -lopencv_highgui -lopencv_ml -lopencv_video -lopencv_features2d -lopencv_calib3d -lopencv_objdetect -lopencv_contrib -lopencv_legacy
错误看起来像,
grfmt_tiff.cpp:(.text._ZN2cv11TiffEncoder12writeLibTiffERKNS_3MatERKSt6vectorIiSaIiEE+0x167): undefined reference to `TIFFSetField'
window_gtk.cpp:(.text.cvNamedWindow+0x29d): undefined reference to `g_type_check_instance_cast'
