We will recreate the project as described in Create a Project; however, this time without the automatic 'Hello World' example C source file. Instead, the example below illustrates how you can manually add a file to your project.
First repeat steps 1 and 2 of Create a TriCore project with the New C/C++ Project wizard in Create a Project.
In the Project type box you can select whether to create an application or a library.
Expand TASKING TriCore Application and select Empty Project. This creates a project without a C source file containing the function main().
Click Next to continue.
The TriCore Project Settings page appears.
Repeat steps 4 through 9 of Create a TriCore project with the New C/C++ Project wizard in Create a Project.
Click Finish to finish the wizard and to create the project.
To add a new, empty file:
In the C/C++ Projects view, right-click on the name of the project, myproject, and select New » Source File.
The New Source File dialog appears.
Specify a source folder and a name for the new file. By default, the new file will be stored in the project folder (in this case: myproject). If your projects contains multiple folders, you can browse for an alternative source folder to store the new file in.
In the Source folder field, make sure it refers to myproject.
In the Source file field, type the name of the new file, for example myfile.c. Note that for C files you must specify the extension .c! For C++ files use the extension .C, .cc, .cpp or .cxx.
In the Template field, select a code template for your source file, for example Default C source template or select <None> if you want to start with an empty file. Note that you can configure your own templates if you click on the Configure... button.
Click Finish to continue.
The new file myfile.c is created and ready for editing in the editor view.
There are three ways to add a file to your project:
Import a file (the original file is copied to the project folder)
Create a file in the project folder
Create a link in the project folder to an existing file
Import a file
Instead of creating a new file, it is also possible to import an existing file into your project or to create a file directly in the myproject folder. To demonstrate this, follow the steps below. Do not close Eclipse.
First create a C source file (for example existing.c) with a standard editor outside Eclipse. (As content you can, for example, use a single line containing comments only).
You can store the file anywhere on your hard disk, but not in your project folder (for example in C:\TEMP ).
In Eclipse, follow the next steps to import the existing file:
In the C/C++ Projects view, right-click on the project myproject and select Import...
The Import wizard appears.
Select General » File System. Click Next to continue.
In the From directory field, type the path to the directory where you saved existing.c (for example C:\TEMP ) and click in the empty white box below.
The left box shows the file structure of the directory, the right box shows the files located in that directory, similar to the Windows Explorer.
In the left box, select the folder TEMP.
In the right box, select the file existing.c.
Click Finish to finish the wizard and import the file into your project.
The file existing.c is copied from its location at C:\TEMP into your project folder and is added to your project. It is now visible as a C source file in the C/C++ Projects view. Changes you make to this file, will not affect the original file stored in C:\TEMP. Also, removing this file from your project will remove the file also from your project folder, but the original file remains untouched.
Create a file in the project folder
Instead of importing a file, you can create the file existing.c with a standard editor outside Eclipse, and store it directly in the myproject folder. To add the file to your project:
In the C/C++ Projects view, right-click on myproject and select Refresh.
The file existing.c should now be visible as part of your project.
Create a link in the project folder to an existing file
The third way to add a file to your project, is to create a link to an existing file which is stored on a different location:
In the C/C++ Projects view, right-click on the project myproject and select New » File from Template.
The New File wizard appears.
Select the project folder in which to create the link: type the name of your project (myproject) or select the project in the box below.
In the File name field, enter a name for the link, for example link2existing.c.
Click the Advanced >> button.
Additional options appear on the dialog to let you create a link to an existing file.
Enable the option Link to file in the file system.
Browse to the location where existing.c is located, select this file and click the Open button.
Click Finish to finish the wizard and create the link to the file in your project.
As we do not need this file for the remainder of this tutorial, we can safely remove it again from the project:
In the C/C++ Projects view, right-click on the file link2existing.c and select Delete.
The link link2existing.c is no longer part of your project and has been removed from your project folder. The original file, however, remains untouched at its original location.
In the C/C++ Projects view, right-click on the file existing.c and select Delete.
The file existing.c is no longer part of your project and has been removed from your project folder.
Be aware that when you remove a file from your project, it always will be removed from its location in the project folder on your hard disk too!
