From 6daa792eab1488d013fefc5eb7e4d01f40f38687 Mon Sep 17 00:00:00 2001 From: Waldemar Brodkorb Date: Sun, 7 Feb 2010 20:03:20 +0100 Subject: change defaults for CONFIG/BUILD/INSTALL styles All packages need an update, so here is a very huge commit. Most of the 460 source packages use automatic style for configuration, building and installing. Make these styles default to "auto". If you have a package, which does not conform to this, just use manual style and add a do-$task make target. I added a new style named AUTOTOOL style, which is needed for some broken packages, which needs to be updated via autoconf or automake. I renamed CONFIGURE_STYLE to CONFIG_STYLE. Updates for some packages, which have newer upstream versions. Renaming of all package/*/extra directories. Use the directory src/ to provide overwrites of source files or to add the code, when no upstream package is available or used. src directory will be automatically used. --- package/ether-wake/Makefile | 9 +- package/ether-wake/extra/ether-wake.c | 386 ---------------------------------- package/ether-wake/src/ether-wake.c | 386 ++++++++++++++++++++++++++++++++++ 3 files changed, 393 insertions(+), 388 deletions(-) delete mode 100644 package/ether-wake/extra/ether-wake.c create mode 100644 package/ether-wake/src/ether-wake.c (limited to 'package/ether-wake') diff --git a/package/ether-wake/Makefile b/package/ether-wake/Makefile index ec8f43ccd..39985ea08 100644 --- a/package/ether-wake/Makefile +++ b/package/ether-wake/Makefile @@ -15,11 +15,16 @@ include ${TOPDIR}/mk/package.mk $(eval $(call PKG_template,ETHER_WAKE,${PKG_NAME},${PKG_VERSION}-${PKG_RELEASE},${PKG_DEPENDS},${PKG_DESCR},${PKG_SECTION})) +CONFIG_STYLE:= manual +BUILD_STYLE:= manual +INSTALL_STYLE:= manual + do-build: - ${TARGET_CC} ${TARGET_CFLAGS} -o ${WRKBUILD}/${PKG_NAME} ${WRKBUILD}/${PKG_NAME}.c + ${TARGET_CC} -Wall ${TCPPFLAGS} ${TCFLAGS} -o \ + ${WRKBUILD}/ether-wake ${WRKBUILD}/ether-wake.c do-install: ${INSTALL_DIR} ${IDIR_ETHER_WAKE}/usr/sbin - ${INSTALL_BIN} ${WRKBUILD}/${PKG_NAME} ${IDIR_ETHER_WAKE}/usr/sbin/ + ${INSTALL_BIN} ${WRKBUILD}/ether-wake ${IDIR_ETHER_WAKE}/usr/sbin/ include ${TOPDIR}/mk/pkg-bottom.mk diff --git a/package/ether-wake/extra/ether-wake.c b/package/ether-wake/extra/ether-wake.c deleted file mode 100644 index 4bee57f90..000000000 --- a/package/ether-wake/extra/ether-wake.c +++ /dev/null @@ -1,386 +0,0 @@ -/* ether-wake.c: Send a magic packet to wake up sleeping machines. */ - -static char version_msg[] = -"ether-wake.c: v1.09 11/12/2003 Donald Becker, http://www.scyld.com/"; -static char brief_usage_msg[] = -"usage: ether-wake [-i ] [-p aa:bb:cc:dd[:ee:ff]] 00:11:22:33:44:55\n" -" Use '-u' to see the complete set of options.\n"; -static char usage_msg[] = -"usage: ether-wake [-i ] [-p aa:bb:cc:dd[:ee:ff]] 00:11:22:33:44:55\n" -"\n" -" This program generates and transmits a Wake-On-LAN (WOL)\n" -" \"Magic Packet\", used for restarting machines that have been\n" -" soft-powered-down (ACPI D3-warm state).\n" -" It currently generates the standard AMD Magic Packet format, with\n" -" an optional password appended.\n" -"\n" -" The single required parameter is the Ethernet MAC (station) address\n" -" of the machine to wake.\n" -" The MAC address may be found with the 'arp' program while the target\n" -" machine is awake.\n" -"\n" -" Options:\n" -" -b Send wake-up packet to the broadcast address.\n" -" -D Increase the debug level.\n" -" -i ifname Use interface IFNAME instead of the default 'eth0'.\n" -" -p Append the four or six byte password PW to the packet.\n" -" A password is only required for a few adapter types.\n" -" The password may be specified in ethernet hex format\n" -" or dotted decimal (Internet address)\n" -" -p 00:22:44:66:88:aa\n" -" -p 192.168.1.1\n"; - -/* - This program generates and transmits a Wake-On-LAN (WOL) "Magic Packet", - used for restarting machines that have been soft-powered-down - (ACPI D3-warm state).
