Join them; it only takes a minute: Sign up Bus error (Core Dumped) up vote bus error (core dumped) c 0 down vote favorite I am trying to run a ROS node which subscribes data from a node and then calculates the PID controller output and publishes it on another topic.But I get a Bus, core dumped error after every 10 cycles...I am not sure why...Here is the code for reference: namespace youbot { PidController::PidController(double P, double I, double D, double I1, double I2) : p_gain_(P), i_gain_(I), how to debug bus error d_gain_(D), i_max_(I1), i_min_(I2) { p_error_last_ = 0.0; p_error_ = 0.0; d_error_ = 0.0; i_error_ = 0.0; cmd_ = 0.0; last_i_error = 0.0; } double PidController::updatePid(double error, boost::posix_time::time_duration dt) { double p_term, d_term, i_term; p_error_ = error; //this is pError = pState-pTarget double deltatime = (double)dt.total_microseconds()/1000.0; //in milli seconds if (deltatime == 0.0 || isnan(error) || isinf(error)) return 0.0; p_term = p_gain_ * p_error_; i_error_ = last_i_error + deltatime * p_error_; last_i_error = deltatime * p_error_; i_term = i_gain_ * i_error_; if (i_term > i_max_) { i_term = i_max_; i_error_=i_term/i_gain_; } else if (i_term < i_min_) { i_term = i_min_; i_error_=i_term/i_gain_; } if (deltatime != 0) { d_error_ = (p_error_ - p_error_last_) / deltatime; p_error_last_ = p_error_; } d_term = d_gain_ * d_error_; cmd_ = -p_term - i_term - d_term; p_error_, i_error_, p_term, i_term, deltatime, cmd_); return cmd_; } } using namespace std; using namespace youbot; double currentPos[3]; void arrayCallback(const geometry_msgs::Point::ConstPtr& cord); double calculateControllerOutput(double pos, double targetPos); int main(int argc, char **argv) { ros::init(argc, argv, "coordinateSubscriber"); ros::NodeHandle n; ros::Subscriber sub3 = n.subscribe("position", 100, arrayCallback); ros::spin(); return 0; } I'm not able to guess which part is causing the error.Any help will be appreciated..Thanks ! c++ ubuntu ros share|improv

Bus Error Core Dumped In Unix
trying to access a memory location outside its address space. The computer detected this problem and sent a signal to your program, which caused it to abort. Things http://stackoverflow.com/questions/19882792/bus-error-core-dumped that cause bus errors and segmentation violations are typically out-of-bounds array references and/or references through uninitialized or mangled pointers. Look very closely in your program for bizarre things like that. A common example in C is: int c; scanf("%d", c); instead of the correct version: int c; scanf("%d", &c); An example from C++ is: int* p=new int[100]; cout<< http://www.glue.umd.edu/afs/glue.umd.edu/system/info/olh/Utilities/Unix_answers/unix_bus_or_seg.html p[100]; instead of the correct version: int* p=new int[100]; cout << p[99] (remember array referances in C and C++ start with 0 ) There are a number of methods for finding out where the program went out of bounds. One method is to use printf() statements to determine how far the program is getting before it crashes, and to print out the contents of interesting variables. A more sophisticated method is using 'dbx', a source level symbolic debugger. C and C++ programmers can also use 'gdb'. To learn about 'dbx', you can read the manual pages by using the 'man' command, as in: man dbx To learn about 'gdb', you can read the manual node in the 'xinfo' program, or using 'M-x info' in Emacs. If you need to debug your program, you may want to enable a core dump. Usually, those two messages above would also have "(core dumped)" by them, indicating that the program wrote an image of its current memory into a file called "core" in that directory. Y
