Exporting Makefiles

If you created a Managed Make C Project, you can use Eclipse* to build a makefile that includes Intel compiler options. See Setting Properties. When your project is complete, you can export your makefile and project source files to another directory, then build your project from the command line using make.

Exporting makefiles

To export your makefile:

1. Select your project in the Eclipse C/C++ Projects view.
2. From the Eclipse File menu, select Export to launch the Export Wizard.
3. On the Select dialog of the Export Wizard, select File system, then click Next.
   
   

4. On the File system dialog, check both the helloworld and Release directories in the left-hand pane. Be sure all the project sources in the right-hand pane are also checked.
   
   Note
   You may deselect some files in the right-hand pane, such as the hello.o object file and helloworld executable. However, you must also select Create directory structure for files in the Options section to successfully create the export directory. This also applies to project files in the helloworld directory.
5. Use the Browse button to target the export to an existing directory. Eclipse can also create a new directory for full paths entered in the To directory text box. If, for example, you specified /code/makefile as the export directory, Eclipse creates two new sub-directories:
• /code/makefile/helloworld
• /code/makefile/helloworld/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  ./hello.o  ./hello.d hello_world

Building file: ../hello.c

Invoking: C Compiler

icc -c -o hello.o ../hello.c

Finished building: ../hello.c

Building target: hello_world

Invoking: Linker

icc -ohello_world ./hello.o

Finished building target: hello_world

This generates the hello_world executable in the same directory.
