FreeRTOS problems under Ubuntu OS

I am trying to run two tasks using FreeRTOS APIs. I followed the Handson Tutorial pdf of FreeRTOS, but my task runs just once and stops.I am using the FreeRTOS kernel on x86 Intel. I am able to compie and run the code. My OS is Ubuntu, I am using Eclipse Toolchain with GCC. If anyone has experience with this, they could give me some pointers as to how to do it right. Here is my code: ~~~ static unsigned long uxQueueSendPassedCount = 0; void vTask1(void *pvParameters) { const char *str_to_display=”This is task1nr”; while(1) { printf(“%s”,str_to_display); vTaskDelay(1000); } } void vTask2(void *pvParameters) { const char *str_to_display=”This is task2nr”;
while(1)
{
  printf("%s",str_to_display);
  vTaskDelay(1000);
}
} int main() {
xTaskCreate(vTask1, (signed char *)"Task1",1000,NULL,3,NULL);
xTaskCreate(vTask2,(signed char *)"Task2",100,NULL,1,NULL);

vTaskStartScheduler();
while(1)
{

}
return 0;
} ~~~ Other things i tried : 1. Created just one task, with infinite loop and it runs as expected, 2. Created just one task, added vtaskDelay, and i get an error “Segmentation fault (core dumped)”

When using the Windows simulating environment, you can not use Windows’ API’s, such as printf(). We did provide a safe way to print logging, see demo_logging.c: ~~~ void vLoggingPrintf( const char *pcFormat, … ); ~~~

Thank you for your response Sir, but i am on Linux. And i adapted my software using this as a basis described here.

I haven’t tried out the simulation under Linux, but I bet that calling printf() is not supported neither.
