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
