Hello,

I think there is a bug, on Linux with the latest RoboDK version, in the RoboDK / bin folder, unable to run RoboDK
Only RoboDK-Start.sh is working.

My problem, with my python application, I have to run RoboDK. programmatically (I use RoboLink.py with the "Connect" function). With Windows OK, Linux not OK

Do you have solution please?

I propose a modification in the code. This allows you to use RoboDK-Start.sh

        def start_robodk(command):
            print('Starting %s\n' % self.APPLICATION_DIR)
            import subprocess
            #import time
            #tstart = time.time()

            from sys import platform as _platform
            if (_platform == "linux" or _platform == "linux2") and os.path.splitext(command[0])[1] == ".sh":
                p = subprocess.Popen(command, shell=True, executable='/bin/bash', stdout=subprocess.PIPE)
            else:
                p = subprocess.Popen(command, stdout=subprocess.PIPE)
            while True:
                line = str(p.stdout.readline().decode("utf-8")).strip()
                print(line)
                if 'running' in line.lower():
                    #telapsed = time.time() - tstart
                    #print("RoboDK startup time: %.3f" % telapsed)
                    break
            
            #with subprocess.Popen(command, stdout=subprocess.PIPE, bufsize=1, universal_newlines=True) as p:
            #    self._ProcessID = p.pid
            #    for line in p.stdout:
            #        line_ok = line.strip()
            #        print(line_ok)
            #        if 'running' in line_ok.lower():
            #            print("RoboDK is running")
            #            return #does not return!!
                        
        import socket
        connected = 0
        for i in range(2):
            for port in range(self.PORT_START,self.PORT_END+1):
                self.COM = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
                self.COM.settimeout(1)
                try:
                    self.COM.connect((self.IP, port))                
                    connected = self._is_connected()
                    if connected > 0:
                        self.COM.settimeout(self.TIMEOUT)
                        break
                except:
                    connected = connected

            if connected > 0:# if status is closed, try to open application
                self.PORT = port
                break;
            elif i == 0:            
                if self.IP != 'localhost':
                    break;
                    
                try:
                    command = [self.APPLICATION_DIR] + self.ARGUMENTS
                    start_robodk(command)                    
                    #import time
                    #time.sleep(5) # wait for RoboDK to start and check network license.
                except:
                    raise Exception('Application path is not correct or could not start: ' + self.APPLICATION_DIR)

        if connected > 0 and not self._verify_connection():
            connected = 0
        return connected

Hi Tonio163, 


Thanks for your feed back, we really appreciate it. 
Happy to see that you manage to fix the problem yourself. 

Note that we will release a new version for Ubuntu next week with this among other corrections.
