Same issue here. Can't build the toolchain on Arch with gcc 7.2.0 due to this flex bug.

上面说 gcc 7.2 有 问题?

修改两个文件,编译过了。遇到有朋友可以借鉴一吓

LT_INIT
AM_INIT_AUTOMAKE([1.11.3 -Wno-portability foreign check-news std-options dist-lzip parallel-tests subdir-objects])
AC_CONFIG_HEADER([src/config.h])

2.修改Buildroot-2017.08/output/build/host-flex-2.6.4/src/scan.l
/* scan.l - scanner for flex input -*-C-*- */

%top{
