g++ finstrument-functions opencv

[shihyuyao]

cmake -D CMAKE_INSTALL_PREFIX=/usr/ local/opencv -D WITH_TBB=ON -D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_V4L=ON -DINSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -DBUILD_EXAMPLES=ON -D CMAKE_BUILD_TYPE=DEBUG -D CMAKE_C_FLAGS=-finstrument - functions -g -D CMAKE_CXX_FLAGS=-finstrument- functions -g ..


有人在opencv使用finstrument-functions ？ 上面是我编译的配置,有人成功过吗可以分享一下步骤吗?

不如先试试“默认”，即 ./configure make

坚决消灭令恢复。

直接 ./configure make 編譯出來好像沒有作用只會打印出local 函數地址 , opencv library 函數地址都沒顯示 g++ `pkg-config --cflags opencv` `pkg-config --libs opencv` -I/usr/local/opencv/include -finstrument-functions -g main.cpp -o main
