[SOLVED] "nano.specs: No such file or directory"

Hi guys,

I just tried to compile Espruino for Pico. Cross compilation seems OK but after a while I got:

...
CC src/jsnative.o
CC src/jsparse.o
CC src/jspin.o
CC src/jsinteractive.o
CC src/jsdevices.o

                                                ^
LD espruino_1v95.237_pico_1r3.elf
arm-none-eabi-gcc: error: nano.specs: No such file or directory
make: *** [espruino_1v95.237_pico_1r3.elf] Error 1

Any idea?

Did you use source scripts/provisio.sh PICO_R1_3 to set up the compiler, or did you use your own?

Looks like you may have used something else? https://stackoverflow.com/questions/26931979/gnu-arm-nano-specs-not-found

I used gcc-arm-none-eabi-5_4-2016q3 that was already on my machine under /usr/local
Then I updated my $PATH with

export PATH=/usr/local/gcc-arm-none-eabi-5_4-2016q3/bin:$PATH

and finally run

make clean &&  BOARD=PICO_R1_3 RELEASE=1 make

Now if I type source scripts/provision.sh PICO_R1_3 it just prints ARM. by calling make it then just tells me the same error with nano.specs

I don't really understand what I missed. Do you suggest to remove+reinstall the complete toolchain?

It's complaining about the option --specs=nano.specs on the Linker command-line, and for whatever reason I guess the compiler you have doesn't have them in.

The provision script checks for GCC before installing it, and in this case I guess it finds it so does nothing. Maybe ensure that it's not in your path, then run provision and it should pull a new compiler into a local folder under Espruino and temporarily set your path.

It'd be a good way to check if that is the problem or not as it doesn't install anything globally.

I had another (old) toolchain installed in /usr/bin previously installed with apt-get .... :-/
Just removed it, run source scripts/provision.sh PICO_R1_3, which actually installed the correct toolchain and after that I just could compile for my Pico. Thanks for the support Gordon!
