Specify Compiler Files

Specify Include Files

The compiler searches the default system areas for include files and items specified by the I compiler option. The compiler searches directories for include files in the following order:

  1. Directories specified by the I option.
  2. Directories specified in the environment variables.
  3. Default include directories.

Use the -nostdinc (Linux) or X (Windows) option to remove the default directories from the include file search path.

For example, to direct the compiler to search the path /alt/include instead of the default path, use the following:

Linux

icpx -nostdinc -I/alt/include prog1.cpp

Windows

icx /X /I\alt\include prog1.cpp 

Specify Assembly Files

You can use the -S and -o options (Linux) or /Fa option (Windows) to specify an alternate name for an assembly file. The compiler generates an assembly file named myasm.s (Linux) or myasm.asm (Windows):

Linux

icpx -S -o myasm.s x.cpp 

Windows

icx /Famyasm x.cpp  

Specify Object Files

You can use the -c and -o options (Linux) or /Fo option (Windows) to specify an alternate name for an object file. In this example, the compiler generates an object file name myobj.o (Linux) or myobj.obj (Windows):

Linux

icpx -c -o myobj.o x.cpp

Windows

icx /Fomyobj x.cpp
