我正在我的 mac osx 上编译 conv-net ( http://conv-net.sourceforge.net/ ) 深度学习库 opencv 和 c++,我似乎无法解决这个错误。这似乎是一个链接问题。所有的 opencv 库都是为 64 位编译的,我尝试在 cmake 中设置 -m64 标志,不,仍然无法正常工作。
我不知道 _cvLoadImage() 链接到哪个库???我正确链接到正确的库,但无法修复这个错误??????
Undefined symbols for architecture x86_64:
"_cvLoadImage", referenced from:
_main in testimg.cpp.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make[2]: *** [testimg] Error 1
make[1]: *** [CMakeFiles/testimg.dir/all] Error 2
我做了一个链接器的-v输出,它显示了这个......
