Hi, I took the 32bit linker script, added same stuff as Asif and saved it
into scripts-directory.
Then I changed the flags in emulator.mk like Pekka instructed:
# LDFLAGS := -m32 -demangle
LDFLAGS := -m32 -demangle -march=i386 -Xlinker -T -Xlinker
../scripts/elf_i386.xc
And got rid of previous errors, but it hang up in main:
g++ -m32 -march=i386 -m32 -demangle -march=i386 -Xlinker -T -Xlinker
../scripts/elf_i386.xc -o sketch main.o sketch.o ellduino.o "-L."
"-L../variants/ellduino" "-lstm32f0" -lstdc++
main.o: In function `emulated_main':
/home/eero/sw-engineering/sulautetut/ng-ell-i/Runtime/stm32/build/../cores/arduelli/main.cpp:36:
