Use eclipse to develop a Linux driver

Previously, the Linux driver was written in plain text. Recently, I found that I could use eclipse for development. So after a long time, I finally succeeded in compiling and felt pretty good. The following uses the hello World driver as an example to describe how to use eclipse to develop the arm-Linux driver.

I will not talk about the installation of eclipse and CDT. After eclipse and CDT are installed, run eclipse, file-> New-> project and select C Project in C/C ++, for example:

Click Next, enter the project name "hello", and set the project path as follows:

Click next and then click Next. Fill in the Cross-compiler prefix and cross-compiler path, as shown below:

Click Finish. The project structure is shown in. It automatically contains several header file paths related to the Cross Compiler:

Right-click Project-> propertise, select paths and symbols in C/C ++ General, select gnu c in the program des tab, and click Add on the right, add the header file directory (which must have been compiled by the cross compiler in advance), as shown below:

Select Add to all deployments, and click OK. On the symbols tab, add a symbols with the name of _ KERNEL __and value of 1, as shown below:

Select Add to all deployments and click OK. Click OK. A dialog box is displayed, as shown in the following figure. Select Yes.

Compile the hello. c file:

 1 # Include <Linux/module. h> /*  Needed by all modules  */  2 # Include <Linux/kernel. h> /*  Needed for kern_info  */  3 # Include <Linux/init. h> /*  Needed for the macros  */  4   5   6   Static   Int _ Init hello_init ( Void  )  7   {  8 Printk (kern_info "  Hello, world \ n "  );  9       Return   0  ;  10   }  11   12   Static   Void _ Exit hello_exit ( Void  )  13   {  14 Printk (kern_info"  Goodbye, world \ n  "  );  15   }  16   17   Module_init (hello_init );  18   Module_exit (hello_exit );  19 Module_license ( "  GPL  " );

Compile the MAKEFILE file:

1OBJ-M + =Hello. o2 3Pwd =$ (Shell PWD)4 5 ALL:6Make-C/gt2440/kernel/Linux-2.6.34.12M =$ (PWD) Modules7 8 Clean:9Rm-f *. O *. Ko
 

After completion, such:

Finally, right-click the project-> properties-> C/C ++ build, and deselect generate makefiles automatically in the builder settings tab, as shown below:

Click OK. Right-click Project> build project to compile the project. The successful compilation result is as follows:

The Hello. Ko file has been generated, and the console output is the same as the compiled output in the terminal.

 

Appendix:

The method to import the original C Project is file-> Import, and select existing projects into workspace under General as follows:

 

Click Next, Click Browse, select the root directory of the project to be imported, and click Finish.
