Hello Harald,

sorry for my misunderstanding, and thank you for helping me.

Ok, here comes the output:

Hi Joerg,

Complete misunderstanding. The paths given by avr-cpp -Wp,-v are include paths, not paths to find executables. I only wanted to know what the output is.

Moving include files around may make things worse. Instead we need to figure out, that the right compiler version is called and that it uses the right include paths.

OK, do the following:

* open a command line window.
* cd to the nutbld directory that you created with the Configurator
* add the paths to your compiler, e.g.
 set PATH=C:\WinAVR\bin;C:\WinAVR\utils\bin;%PATH%
* run "avr-gcc --version" and "avr-cpp -Wp,-v"
* post the complete cmds and responses to this list (text via cut and copy, no screenshot)
* run "make clean all install"
* if that ends with an error, post the error message to this list (not the full dump, just the 2 or 3 lines containing the first error)

If that sequence fails in between, then post the output up to this point.

The old version used it's own integer types, while we later switched to stdint.h, because it is standard and nowadays support by most libraries.
In that sense, the newer Nut/OS versions depend a bit more on the library. But your case is so common, that it must work. It's just a problem of your two avr-gcc versions installed on your hard disk. This needs to be sorted out.

I usually have at least 10 different compiler versions installed. With little care this provides no problems.
