This section provides information about makefile project types and exporting makefiles.

Project Types and Makefiles

When you create a new project in Eclipse*, there are
Executable
,
Shared Library
,
Static Library
, or
Makefile
 project types available for your selection.
  • Select
    Makefile Project
     if the project already includes a makefile.
  • Use
    Executable
    ,
    Shared Library
    , or
    Static Library Project
     to build a makefile using options assigned from property pages specific to the
    Intel® oneAPI
    DPC++/C++
     Compiler
    .

Export Makefiles

Eclipse can build a makefile that includes
Intel® oneAPI
DPC++/C++
 Compiler
 options for created
Executables
,
Shared Libraries
, or
Static Library
Projects. When the project is complete, export the makefile and project source files to another directory, and then build the project from the command line using
make
.
To export the makefile:
  1. Select the project in the Eclipse
    Project Explorer
     view.
  2. Select
    File
    Export
     to launch the
    Export Wizard
    . The
    Export
    dialog box opens, showing the
    Select
    screen.
  3. Select
    General
    File system
    , then click
    Next
    . The
    File System
     screen opens.
  4. Check both the
    hello_world
     and
    Release
     directories in the left-hand pane. Ensure all project sources are checked in the right-hand pane.
    Some files in the right-hand pane may be deselected, such as the
    hello_world.o
     object file and the
    hello_world
     executable.
    Create directory structure for files
     in the
    Options
     section must be selected to successfully create the export directory. This process applies to project files in the
    hello_world
     directory.
  5. Use the
    Browse
     button to target the export to an existing directory. Eclipse can create a directory for full paths entered in the
    To directory
     text box. For example, if the
    /code/makefile
     is specified as the export directory, Eclipse creates two new subdirectories:
    • /code/makefile/hello_world
    • /code/makefile/hello_world/Release
  6. Click
    Finish
     to complete the export.

Run Make

From the command line, change to your project directory and run
make
 with: 
make clean all
You should see the following output: 
rm -rf  ./new_source_file.o  ./new_source_file.d  hello_world
 
Building file: ../new_source_file.c
Invoking: Intel C++ Compiler
icx -O2 -MMD -MP -MF"new_source_file.d" -MT"new_source_file.d" -c -o "new_source_file.o" "../new_source_file.c"
Finished building: ../new_source_file.c
 
Building target: hello_world
Invoking: Intel C++ compiler
icx  -o "hello_world"  ./new_source_file.o   
Finished building target: hello_world
This process generates the
hello_world
 executable in the project directory.
