Build error on arm32v7/debian:stretch

[devster31]

I'm encountering the below error on a clean system after following instruction and documentation.

checking for XMLRPC-C... failed
configure: error: Could not compile XMLRPC-C test.

and here the entire history of commands ran:

    1  apt update && apt-get install sudo locales lsb-release build-essential pkg-config     subversion git time lsof binutils tmux curl wget     python-setuptools python-virtualenv python-dev     libssl-dev zlib1g-dev libncurses-dev libncursesw5-dev     libcppunit-dev autoconf automake libtool     libffi-dev libxml2-dev libxslt1-dev
    2  git clone https://github.com/pyroscope/rtorrent-ps.git
    3  cd rtorrent-ps/
    4  ./build.sh install
    5  history

The system is a Scaleway server (C1) with an armv7l_armhf CPU (Marvell Armada I believe).

The failure is, as far as I can see, during the building steps for rtorrent itself.

Read your configure.log. This is a problem of your environment.

Here the incriminated log rtorrent-0.9.6/config.log:

configure:18591: result: failed
configure:18593: error: Could not compile XMLRPC-C test.

This also happens, with the same error output, with the ./build.sh docker_deb arm32v7/debian:stretch (this is needed because of moby/moby#34875 which would otherwise pull an armel image instead of an armhf image as appropriate).

My best guess is that it's related to these lines:

rtorrent-ps/build.sh

Lines 136 to 157 in 66e43c4

	export USE_CXXFLAGS=true
	if command which dpkg-architecture >/dev/null && dpkg-architecture -earmhf; then
	GCC_TYPE="Raspbian"
	elif command which gcc >/dev/null; then
	GCC_TYPE=$(gcc --version | head -n1 | tr -s '()' ' ' | cut -f2 -d' ')
	# Fix libtorrent bug with gcc version >= 6 and non-empty CXXFLAGS env var
	GCC_MAIN_VER=$(gcc --version | head -n1 | cut -d' ' -f4 | cut -d'.' -f1)
	test "${GCC_MAIN_VER:-0}" -ge 6 && export USE_CXXFLAGS=false || :
	else
	GCC_TYPE=none
	fi
	case "$GCC_TYPE" in
	# Raspberry Pi 2 with one of
	# gcc (Debian 4.6.3-14+rpi1) 4.6.3
	# gcc (Raspbian 4.8.2-21~rpi3rpi1) 4.8.2
	Raspbian)
	if uname -a | grep 'armv7' >/dev/null; then
	export CFLAGS="$CFLAGS -march=armv7-a -mfpu=neon-vfpv4 -mfloat-abi=hard"
	export CFG_OPTS_LT="$CFG_OPTS_LT --disable-instrumentation"
	fi
	;;
	esac

which may not be necessary anymore since gcc is now -ge 6 in arm32v7/debian:stretch.

This line in particular seems to be the culprit

rtorrent-ps/build.sh

Line 153 in 66e43c4

export CFLAGS="$CFLAGS -march=armv7-a -mfpu=neon-vfpv4 -mfloat-abi=hard"

commenting it out seems to solve the issue.

@devster31 I need an uname -a instead of the GCC version, and quick (before Sunday) if you want it in the upcoming 1.1 release.
