Greetings Toradex Team!
I’m having some trouble to view an application logs (printf) when using this process as a service. I am basically trying to run this code:
#include <stdio.h>
#include <unistd.h>
int main(int argc, char *argv[]) {
while (1) {
printf("hello world!\r\n");
sleep(5);
}
return 0;
}
Also, I created a systemd service with this service file:
[Unit]
Description=Demo service
After=network.target
StartLimitIntervalSec=0
[Service]
Type=simple
Restart=always
RestartSec=1
User=root
StandardOutput=file:/home/root/log1.log
StandardError=file:/home/root/log2.log
SyslogIdentifier=demo_service
WorkingDirectory=/home/root
ExecStart=/home/root/theDemo
[Install]
WantedBy=multi-user.target
After starting the service, I can see that the it created the log1.log file on my home directory. However, no matter what I do the file is always empty. I have also tried to export the logs to syslog, but I have zero experience with that and got nowhere…
