Hi all,

Here with another build error today, this time against Alpine linux.

Building under an Alpine container with the following world set:

  alpine-baselayout
  alpine-keys
  alpine-sdk
  apk-tools
  bash
  bc
  busybox
  curl
  file
  gettext
  libc-utils
  libintl
  libtool
  make
  musl-dev
  ncurses
  patch
  perl
  python
  rsync
  wget

I get the following error attempting to build:

  libtool: link: /usr/bin/gcc -W -Wall -Wstrict-prototypes -Wmissing-prototypes -Wshadow -Wstack-usage=26214

A reproduction in Docker is possible with the following Dockerfile:

FROM alpine:edge
RUN apk --update upgrade
RUN apk add make git bash ncurses gcc wget curl \
    musl-dev file g++ perl python rsync bc patch \
    libintl libtool alpine-sdk gettext
RUN adduser -D -u 1000 -g 1001 buildroot && \
    mkdir -p /home/buildroot && chown buildroot:buildroot /home/buildroot
USER buildroot
WORKDIR /home/buildroot

Then:

cd buildroot/
docker build -t "buildroot:latest" .
docker run -v $(pwd):/home/buildroot/ --rm -it buildroot:latest sh
$ make clean
$ make defconfig BR2_DEFCONFIG=configs/raspberrypi3_defconfig
$ make

I would assume this is some incompatibility when trying to link against
the latest versions of libintl or gettext or so.

In addition to my own config, I attempted the uclibc-based pi 3
defconfig:

$ make clean
$ make defconfig BR2_DEFCONFIG=configs/raspberrypi3_defconfig
$ make

Result:
