c++ - rosrun via ssh doesnt start a node properly -

-

we working ros , try run node via ssh in shell script. have controlling (master) computer on execute script following line:

ssh user@xxx.xxx.x.x -x "/bin/bash -c 'source /etc/profile; rosrun stargazer_alter stargazer_node'"

the node getting started (it occurs in "rosnode list" , node listed publisher in "rostopic info") main method seems not executed (neither print lines show nor messages published).

#include "stargazer_listener.h"  enum states {config, readdata};  int main(int argc, char** argv) {    ros_info("test!!!! stargazer starts!");    ros::init(argc, argv, "stargazer_node");    stargazer_listener starg;    int ifd = 0;    char *rec_msg = (char*)malloc(buffsize * sizeof(char));    ifd = starg.portsetup();    states state = config;    while(ros::ok()) {      switch(state) {        case config:          starg.cmd(ifd, rec_msg, "~#calcstop`");          printf("calcstop\n");          starg.cmd(ifd, rec_msg, "~#calcstart`");          printf("calcstart\n");          state = readdata;          break;        case readdata:          starg.publish_data(ifd, rec_msg);          break;      }    }    free(rec_msg);    return 0; }

the line "starg.portsetup()" opens ttyusb0 port not used other processes.

the stargazer_node getting compiled via catkin_make. according code, first thing happen should following print line: "ros_info("test!!!! stargazer starts!");". doesnt happen!

the same shell script command did work fine other nodes. if add node ros ".launch" file, same thing happens.

if connect via ssh in terminal (ssh user@xxx.xxx.x.x) , run same line (rosrun stargazer_alter stargazer_node) works fine!

i need hash algorithm produces 64-bit hash code ( long ) fewer collisions string.gethashcode() , fast (no expensive calls cryptographic functions). here's implementation of fnv still shows 3% of collisions after testing 2 million random strings. need number way lower. void main() { const string chars = "abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz!#@$%^&*()_+}{\":?><,./;'[]0123456789\\"; const int n = 2000000; var random = new random(); var hashes = new hashset<long>(); int collisions = 0; for(int = 0; < n; i++) { var len = random.next(chars.length); var str = new char[len]; (int j = 0; j < len; j++) { str[j] = chars[random.next(chars.length)]; } var s = new string(str); if(!hashes.add(get64bithash( s ))) collisions++; } console.writeline("collision percentage after " + n + " random strings: " + ((doubl
