Take a closer look at your Makefile. Each line that is indented should begin not with spaces, but with a tab character. This is an important concept in Makefiles.
If that does not fix your problem, please consider this:
With makefiles, it's important to be able to see which lines are indented from the lefthand margin.
Could you please repost this makefile, not between QUOTE tags, but between CODE tags? That will help us to see what is indented and what is not.
To do this:
- Click the Go Advanced button at the bottom of your editing window.
- If you have not already done so, insert the content of your Makefile into this new editing window.
- Highlight that content with your mouse.
- Click the # icon at the top of the editing window.
