[Freemint-discuss] LIBCmini don't build with Gcc ELF 13.2.0

[Daroou <da...@fr...>]

Bonjour,


I'm currently testing Vincent Rivière's m68k-atari-mintelf cross-tools 
(under cygwin)

'Hello world' compiles perfectly with Mintlib.

However, I want to use LIBCmini for my programs.

https://github.com/freemint/libcmini

GCC ELF refuses to compile LIBCmini because of this error:

[Makefile]

BUILD_FAST=N
BUILD_SOFT_FLOAT=Y
BUILD_SHORT=Y
COMPILE_ELF=Y

Compiles perfectly with standard GCC
