xtensa-lx106-elf-gcc: error: unrecognized command line option '-mforce-l32'
make[1]: *** [: lwip/core/def.o] Error 1
default: make[1]: Leaving directory '/home/vagrant/esp-open-sdk/esp-open-lwip'

The compilation is ran on ubuntu-20.04

This results later on the compilation of the micropython with the same error.

May be this patch could work
https://raw.githubusercontent.com/earlephilhower/esp-quick-toolchain/master/patches/gcc9.2/gcc-mforce-l32.patch
but I'm not an expert.

Hi

I am trying to get 64 bit and float working in libc (printf). It doesn't work at the moment, because apparently support is not compiled. This gives me the same functionality as ets_(vsn_)printf, so that doesn't help ;-)

I found these in the .config file, which suppose are the entries I'd need to change:

# CT_LIBC_NEWLIB_IO_C99FMT is not set
# CT_LIBC_NEWLIB_IO_LL is not set
# CT_LIBC_NEWLIB_IO_FLOAT is not set

Now this file is "git ignored" so very probably generated at some point. So if I change it here, my changes will get lost. Do you know where I can change this and have it working? Would you consider change this as well in (your) upstream version?

I'm trying to run make in someburner/esp-open-sdk but it fails with:

[INFO ]  Retrieving needed toolchain components' tarballs

This issue was fixed upstream in 1.25 release: crosstool-ng/crosstool-ng#1625 (comment)

So looks like update is required.

Bonus: for some reason issues are disabled in someburner/esp-open-sdk repo.

Hi someburner,

Now esp-open-sdk compiles successfully.

But sysroot is not returned when

vagrant@ubuntu-focal:~/esp-open-sdk$ xtensa-lx106-elf-gcc -print-sysroot
vagrant@ubuntu-focal:~/esp-open-sdk$

is called and this breaks the esp8266 micropython compilation.

This is the compilator info
