Compile error

I get this, when I compile:

/home/poul/Programmer/gcc-arm-none-eabi-5_3-2016q1/bin/../lib/gcc/arm-none-eabi/5.3.1/../../../../arm-none-eabi/bin/ld: section .init loaded at [0005bcc0,0005bcc3] overlaps section .data loaded at [0005bcc0,0005c237]
collect2: error: ld returned 1 exit status
make: *** [espruino_1v85.63_pico_1r3.elf] Fejl 1

In makefile l have this:

PICO_1V3=1
RELEASE=1
SINGLETHREAD=1
  export CCPREFIX?=/home/poul/Programmer/gcc-arm-none-eabi-5_3-2016q1/bin/arm-none-eabi-

What have done wrong?

I am running on Linux Mint 17.3 64 bit.

I'm not really sure. It seems that happens if sections overlap, but it's slightly confusing that .init contains only 4 bytes.

Have you changed the code at all?

I'd maybe look at using an earlier compiler like 4.9 - I haven't used 5.3 (the release was only 3 days ago), and that could potentially be an issue.

No, I have not changed the code, I will first compile the code as is, before I make any changes.

It was the compiler.

gcc-arm-none-eabi-4_9-2015q3, works
gcc-arm-none-eabi-5_2-2015q4, does not work
gcc-arm-none-eabi-5_3-2016q1, does not work

Thank you very much

Thanks for the update!

It's a bit frustrating really - it seems like every single time the compiler is updated, the build needs tweaking to make it work again.

I've now tweaked the build so it works on GCC 5.3
