[SCRIPT] dmake -- distcc make

[drizztbsd]

Oggi mi sono fatto uno script per gestire comodamente la compilazione con distcc
Le features sono le seguenti:

• Utilizza di ccache e/o distcc automaticamente se rilevati
• Supporto cross-distcc
• Supporto porte diverse da quelle standard e numero jobs

L'unico problema per ora è che devi usare la sintassi col numero jobs (host/num o host:port/num)

Code: Select all

einfo() {
	echo -e " \e[32;01m*\e[0m $*"
}

ewarn() {
	echo -e " \e[33;01m*\e[0m $*" >&2
}

CHOST=$(gcc -v 2>&1 | awk '/^Target: /{print $2}')
export AS="/usr/${CHOST}/bin/as"
export LD="/usr/${CHOST}/bin/ld"

if type ccache &>/dev/null; then
	einfo ccache detected

		for i in $(</etc/distcc/hosts); do
			ip=${i%/*}
			port=${ip#*:}
			[[ "${port}" = "${ip}" ]] && port=3632 || ip=${ip%:*}
			if ( > "/dev/tcp/${ip}/${port}" ) 2>/dev/null || [[ ${ip} = localhost ]]; then
				DISTCC_HOSTS="${DISTCC_HOSTS} ${i}"
			else
				ewarn "${ip}:${port} is not available."

	fi
    if [[ "${DISTCC_HOSTS}" ]]; then
        export DISTCC_HOSTS=${DISTCC_HOSTS}
        MAKEOPTS="-j$(($(for i in ${DISTCC_HOSTS}; do echo -n ${i#*/}+; done ; echo 0)))"

	fi
        einfo "I'm using distcc with \"${DISTCC_HOSTS}\""
    fi
fi

make -e ${MAKEOPTS} $*

Per gli host usare distcc-config
