Getting Eclipse CDT to use relative include paths in generated Makefiles

Question

I am using the Eclipse CDT. I have configured the "external Builder" and I am generating the Makefiles automatically. Unfortunately, the generated Makefiles contain the absolute include path. I would like to use the generated Makefiles on other systems (where Eclipse is not installed) - is there a way to make Eclipse use relative paths into the Makefile?

I have configured my projects include directory under Settings -> Tool Settings -> GCC C Compiler -> Include Paths using ${workspace_log}.

Solution 1

If you use relative path in the 'include paths' (instead of ${workspace_loc}), then the makefile (and .mk files it uses) will include relative paths as well.

Solution 2

The relative paths you add in "Project > Properties > C/C++ General > Paths and Symbols > Includes" tab are relative to your project folder.

The ones that appear in the generated makefiles are relative to the main Makefile location.

The accepted answer below works for include paths in the project, but what about linked resource files? My generated makefile still contains absolute paths sources files. Do you not use linked sources in your project? How can you compile on other systems?

Relative from where though?

[dtmland]

By chance do you how to achieve the same for linked source files? They are still being set to absolute in my generated makefiles?

No, sorry... I haven't worked with Eclipse in about 4 years.

.Same problem here. Linked resource, move project to another machine, it fails because of absolute path for linked resources (.h files).
