[Error]: ## ERROR parseLaunchfileSetParameter(): Tag-Value setting not valid. #355

Good morning, I have a problem opening Sick LMS4000 laser: SickScanApiInitByCli return 0, but I think there's a problem parsing the xml file. (The xml file is ok because I tested it using the original example and it works well). I attach the solution. Could you help me? Thank you Maurizio

Thanks for your feedback! We could reproduce that error. The arguments provided by argv is allocated on the stack and immediately freed after SickScanApiInitByCli, but still used for parsing in the background. We will correct this behaviour by creating a deep copy of the argv arguments and provide an update.

In the meantime, please replace argv in your file laserSick.cpp line 141 by a static variable: static char* argv[2]; This way the memory in argv remains intact until the lidar is completely initialized.

ok, using "static char* argv[2]" it works! Thank you
