Testing the installation

To test the product installation and the critical search paths, try building, compiling, and running a simple program.

For example:

1. Create the following C program:

   [hello.c]
   #include <stdio.h>
   int main(void)
   {
      printf("Hello World!\n");
      return 0;
   }

2. Compile the test program. For example:

   xlc hello.c -o hello

   Note: To use shortcuts to the compiler invocation commands, see Creating shortcuts to the XL C invocation commands. Otherwise, include the full path to the commands to compile the program.
3. Run the program:

   ./hello

   The expected result is that "Hello World!" is displayed on the screen.

4. Check the exit code of the program:

   echo $?

   The result is zero.
