[En-Nut-Discussion] Nut/OS configurator Floating point activation leads to compiler error (.elf file)

[Philipp Drey]

Hello,

I'm working with an EtherNut 2.1B board. As in my program code floating
point operations are needed, I activated  floating point in the Nut/OS
configurator, like discribed in the NutWiki. Afte compiling with the new
config file, I get an error (I think while building the .elf file, or
somewhere after line 33).
I am working on a WinXP PC and complie on the command line.
Here is  the output from the console:

Since I'm not an expert in programming, I don't understand the error
message. I hope someone can tell me where to search the error.
