Hello *,

I'm trying to compile my first "Hello World" project using Eclipse and
the Codesourcery tool chain. I have configured and installed everything
but I get this error when try to compile:

***multiple target patterns. Stop.


Here is the code of the makefile and the line where the error comes:

Please, can some one help me with this topic? I don’t have any
experience with makefile, I looked already the documentation on the GNU
website and many forums but couldn’t find any solution.


Many thanks in advance

Suggestion 1: Try to ensure that there are no spaces(as in Program
Files) in the installation path.

Suggestion 2: Shouldn't that be %.o and %.c ??

Suggestion 3: %.elf ?? Did you make an error when copying the Makefile?

Neither do I(atleast, not that much). Just google "Makefile tutorials".
You will end up learning about Makefiles anyway, so why not start now :)

Thank you for your answer.
I solve the problem by writing the include statements like that:

INCDIR += -IC:/CodeSourcery/SourceryGLite/m68k-elf/include   \
  -IC:/CodeSourcery/SourceryGLite/lib/gcc/m68k-elf/4.3.2/include

I change the directory of the include files to avoid whitespaces,
although it also can work by writing the whitespaces as "\ ".

I foud out that tabs are also very important.

Thanks again.
