Newlib build fails

[Keith Clifford]

Hi,

I am building newlib for a MinGW cross compiler tool chain for ARM, M68K,
and PowerPC. The build fails in all cases and I've included a patch that
allows me to get the build to work.

 

The pertinent details are:

Newlib version:  4.3.0

Build system: CYGWIN_NT-10.0-19045 Keith-PC 3.4.6-1.x86_64 2023-02-14 13:23
UTC x86_64 Cygwin

Host: MinGW

Target: arm-eabi, m68k-elf, and powerpc-eabi   (see ${TARGET} below)

Configure parameters: --target=${TARGET} --prefix=${PREFIX}

 

The -print-multi-lib option for the respective built gcc generates output
for which the end of line is "\r\n" and config-ml.in leaves the '\r' in the
"flags" variable, in the following patch, confusing subsequent processing. 

 

PATCH FILE STARTS:

>From cac29dd969f33e9cfb1b24c0e3ba28ea499d96e6 Mon Sep 17 00:00:00 2001

From: kclifford <kclifford@tranaptic.ca>

Date: Fri, 16 Jun 2023 17:57:54 +0100

Subject: [PATCH] Patches to get gcc version 13.1.0 to build successfully.
