Eclipse building system investigation report

by Rockins Chen<>, 03/21/08

What's the target of this investigation?

A: Investigate whether there's a mechanism in Eclipse, which can ease the source tree building pain in Linux.

Can eclipse do building task?

A: Yes, of course. It does, indeed.

What is needed to build?

A: Usually GNU make or other equivalence. Besides, you have to install CDT plug-in for eclipse.

Can eclipse generate Makefile automatically?

A: Yes.

Can user write customized Makefile manually?

A: Yes.

Can eclipse build kernel module?

A: Yes. Since eclipse does not care about what you're doing, all its work is calling make to execute the Makefile/makefile.

Is there any button or short key for building?

A: Yes. You can customize the building feature as a button.

Is there anything should be taken care of?

A: Following rule is very important: When writing a makefile manually, you must make sure that the beginning of an action line is started by a TAB. In most situations, eclipse editor choose to replace TAB with 4/8 SPACE. So, if you end up with following error message when building a C/C++ project:

Makefile:2: *** missing separator. Stop.

You must first check whether the TAB is replaced by SPACE. If so, then you should go to Window->Preferences->General->Editors->Text Editors page, toggle the “Insert spaces for tabs” option off.
