[En-Nut-Discussion] No rule to make ...

[Nikolas Becker]

Hello Uwe,

I'm really sorry, I just downloaded the newest version from the ethernut page and followed the tutorial which recommends yagarto. 

I visited the repository and downloaded the head revision. Sadly, I have no idea how to build the newest version from the source, so I just tried to copy the newer files over my already installed 5.2.4 build. 
I then installed the gnu arm toolchain as recommended by you. 
I accepted all licenses under the non-BSDL code section.
With GNU ARM Toolchain, I get the following log:

With Yagarto, I get the following log:

Isn't there perhaps an older, known stable release, where I just can compile the basic nut library for my ethernut5?
