您似乎没有正确链接 yaml-cpp
库.编译时添加参数-lyaml-cpp
.例如:
It seems that you are not properly linking the yaml-cpp
library. Add the argument -lyaml-cpp
when compiling. For example:
g++ -I/usr/local/include -L/usr/local/lib -lyaml-cpp -o test main.cpp
另一种选择是将此 cmake 包含到您的 CMakeLists.txt 中:
Another option is to include this cmake to your CMakeLists.txt:
# attempt to find static library first if this is set
if(YAMLCPP_STATIC_LIBRARY)
set(YAMLCPP_STATIC libyaml-cpp.a)
endif()
# find the yaml-cpp include directory
find_path(YAMLCPP_INCLUDE_DIR yaml-cpp/yaml.h
