Hi!
I am trying to create a very first Hello World project like that:
/**

#if !defined(__SOFT_FP__) && defined(__ARM_FP)
#warning "FPU is not initialized, but the project is compiling for an FPU. Please initialize the FPU before use."
#endif
#include<stdio.h>
int main(void)
{
printf("Hello World\n");
for(;;);
}
But I have encountered an error like that:
14:35:10 **** Incremental Build of configuration Debug for project 001HelloWorld ****

How can I solve it. Thanks for all the help!
