libnewlib-arm-none-eabi: Multilib directory structure incompatible with gcc

[Björn Haase]

stumbled over the very same issue "libnewlib-arm-none-eabi: Multilib directory structure incompatible with gcc"

which has been verified to be valid also by debian guys for ubutu 18.04

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=899264

Basically the version of the newlib library does not seem to match with the version of gcc. When linking, gcc-6.3.1 seems to expect other multilib directory structures than provided by newlib.

As a result, linking fails, e.g. for Cortex-M4 code using hard-float support.

The bug has been reproduced for ubuntu 18.04 by others from the debian distribution team

According to Agustin Henze <email address hidden> , Ubuntu just needs to choose the right and most recent package from the debian distribution.

Björn

manually installing the libnewlib-arm-none-eabi_3.0.0.20180802-2_all.deb package did fix the problem for me.

Status changed to 'Confirmed' because the bug affects multiple users.

[Thomas Preud'homme (thomas-preudhomme)]

The problem is actually in newlib, a newer newlib should be taken from Debian or newlib should be rebuilt against Ubuntu's gcc-arm-none-eabi. The following bug already reports the issue and an affect for newlib in Ubuntu has been added: https://bugs.launchpad.net/ubuntu/+source/newlib/+bug/1772332
