A simple Hello World application can demonstrate some of the debugger's basic features.
To prepare helloworld in C:
Create a new file named helloworld.c in a working directory. Add the following code to helloworld.c:
#include <stdio.h>
int main()
{
printf("Hello World!\n");
return 0;
}
Note
The Intel Debugger does not support position independent executable (pie).
On some systems the compiler option -fpie is set by default. Use -fno-pie to disable pie.
To compile helloworld.c:
Before compiling you must set the environment variables as described in the compiler User Guide.
- Open a shell and change to the working directory.
Compile the application:
On Linux* OS, compile the application using the following command:
icc -debug -O0 helloworld.c -o helloworld
Following successful compilation, the compiler creates an executable named helloworld in the working directory.
To prepare helloworld in Fortran:
Create a new file named helloworld.f90 in a working directory. Add the following code to helloworld.f90:
program main print *,"Hello World!" end program main
To compile helloworld.c:
Open a shell and change to the working directory.
Compile the application:
On Linux* OS, compile the application using the following command:
ifort -debug -O0 helloworld.f90 -o helloworld
Following successful compilation, the compiler creates an executable named helloworld in the working directory.
