Exporting 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
.

Exporting makefiles

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.exe
    executable. The,
    Create directory structure for files
    in the
    Options
    section must be selected to successfully create the export directory. This 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 new 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 sub-directories:
    • /code/makefile/hello_world
    • /code/makefile/hello_world/Release
  6. Click
    Finish
    to complete the export.

Running make

In a terminal window, change to the
/cpp/hello_world/Release
directory, then run
make
by typing:
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 DPCPP/CPP 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 DPCPP/CPP Linker icx -o "hello_world" ./new_source_file.o Finished building target: hello_world
This generates the
hello_world.exe
executable in the same directory.
