- All DEFINE macros take the same three arguments: the name of the flag, its default value, and a 'help' string that describes its use. The 'help' string is displayed when the user runs the application with the
--help
flag.
#include <gflags/gflags.h>
DEFINE_string(config, "./config/default.yaml", "config file path");
int main(int argc, char **argv) {
google::ParseCommandLineFlags(&argc, &argv, true);
myslam::VisualOdometry::Ptr vo(new myslam::VisualOdometry(FLAGS_config));
...
}
// in visual_odometry.h
VisualOdometry(std::string &config_path);
