Use Makefiles for Compilation

This topic describes the use of makefiles to compile your application. You can use makefiles to specify a number of files with various paths, and to save this information for multiple compilations.

Linux

To run make from the command line using the compiler, make sure that /usr/bin and /usr/local/bin are in your PATH environment variable.

If you use the C shell, you can edit your .cshrc file and add the following:

setenv PATH /usr/bin:/usr/local/bin:$PATH

To use the compiler, your makefile must include the setting CC=icx, CC=icpx, or CC=icpx -fsycl. Use the same setting on the command line to instruct the makefile to use the compiler. If your makefile is written for GCC, you need to change the command line options that are not recognized by the compiler. Run make, using the following syntax:

make -f yourmakefile

Where -f is the make command option to specify a particular makefile name.

Windows

To use a makefile to compile your source files, use the nmake command with the following syntax:

nmake /f [makefile_name.mak] CPP=[compiler_name] [LINK32=[linker_name]

Example:

nmake /f your_project.mak CPP=icx LINK32=link

NOTE:
If you have link/xilink specific options that are not accepted by icx-cl -fsycl, ensure any linker specific options are placed after the /link option.

Argument

Description

/f

The nmake option to specify a makefile.

your_project.mak

The makefile used to generate object and executable files.

CPP

The preprocessor/compiler that generates object and executable files. (The name of this macro may be different for your makefile.)

LINK32

The linker that is used.

The nmake command creates object files (.obj) and executable files () from the information specified in the your_project.mak makefile.
