From: Kim Jones Date: Mon, 8 Aug 2016 12:30:56 +0000 (+0100) Subject: dpdkstat: rework X-Git-Tag: collectd-5.7.0~73^2~5 X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=dbc37ea39ffde66b9bf6f389a7a8f65ab6d7f8f5;p=collectd.git dpdkstat: rework 1) Declaring int i = 0 in for loop 2) Removed -fPIC flag 3) Fixed indentation 4) Changed true and false to yes and no 5) Fixed empty var issue when --with-libdpdk=yes 6) Changed DPDK_LIB to DPDK_EXTRA_LIB (typo) 7) Removed dead code & FOUND_DPDK after AC_MSG_ERROR 8) Changed AC_CHECK_FILE to AC_CHECK_HEADER 9) Restructured DPDK part of configure.ac 10) Add comment explaining no-as-needed flag. 11) Added new if_* types to types.db 12) Updated type & type inst. selection for xstats Change-Id: I7fb48852d8d0b94b4c67f204f1b1b430681e4509 Signed-off-by: Kim Jones --- diff --git a/configure.ac b/configure.ac index 82ea4bb2..42e55883 100644 --- a/configure.ac +++ b/configure.ac @@ -2416,56 +2416,70 @@ AC_ARG_WITH(libdpdk, [AS_HELP_STRING([--with-libdpdk@<:@=PREFIX@:>@], [Path to t [ if test "x$withval" != "xno" && test "x$withval" != "xyes" then - with_dpdk_path="$withval" + RTE_BUILD="$withval" with_libdpdk="yes" else - if test "x$withval" = "xno" - then - with_libdpdk="no (disabled)" - fi + RTE_BUILD="/usr" + with_libdpdk="$withval" fi + DPDK_INCLUDE="$RTE_BUILD/include" + DPDK_LIB_DIR="$RTE_BUILD/lib" + FOUND_DPDK=yes ], [with_libdpdk="no"]) if test "x$with_libdpdk" = "xyes" then - RTE_BUILD="$with_dpdk_path" - DPDK_INCLUDE="$RTE_BUILD/include" - AC_CHECK_FILE([$DPDK_INCLUDE/rte_config.h], [LOCAL_DPDK_INSTALL=true], - [AC_CHECK_FILE([$DPDK_INCLUDE/dpdk/rte_config.h], - [DPDK_INCLUDE=$DPDK_INCLUDE/dpdk], [])]) - DPDK_LIB_DIR="$RTE_BUILD/lib" - DPDK_EXTRA_LIB="" + LOCAL_DPDK_INSTALL="no" + AC_CHECK_HEADER([$DPDK_INCLUDE/rte_config.h], [LOCAL_DPDK_INSTALL=yes], + [AC_CHECK_HEADER([$DPDK_INCLUDE/dpdk/rte_config.h], + [], + [FOUND_DPDK=no], [])], []) - SAVE_CFLAGS="$CFLAGS" + if test "x$LOCAL_DPDK_INSTALL" = "xno" + then + DPDK_INCLUDE=$DPDK_INCLUDE/dpdk + fi + + if test "x$FOUND_DPDK" = "xno" + then + AC_MSG_ERROR([libdpdk error: rte_config.h not found]) + fi +fi + +if test "x$with_libdpdk" = "xyes" +then SAVE_LDFLAGS="$LDFLAGS" - CFLAGS="$CFLAGS -I$DPDK_INCLUDE" - if test "x$LOCAL_DPDK_INSTALL" != "xtrue" - then - LDFLAGS="$LDFLAGS -L$DPDK_LIB_DIR" + + if test "x$LOCAL_DPDK_INSTALL" != "xyes" + then + LDFLAGS="$LDFLAGS -L$DPDK_LIB_DIR" fi - FOUND_DPDK=false - SAVE_LIBS="$LIBS" - LIBS="$DPDK_LIB $LIBS" + AC_CHECK_LIB(dpdk, rte_eal_init, - [FOUND_DPDK=true], - [AC_MSG_ERROR([did not find dpdk libs ])]) + [BUILD_WITH_DPDK_LIBS="-Wl,-ldpdk"], + [FOUND_DPDK=no]) - CFLAGS="$SAVE_CFLAGS" LDFLAGS="$SAVE_LDFLAGS" - LIBS="$SAVE_LIBS" - if test "x$FOUND_DPDK" != "xtrue" - then - AC_MSG_ERROR([cannot link with dpdk in $DPDK_LIB_DIR]) + if test "x$FOUND_DPDK" = "xno" + then + AC_MSG_ERROR([libdpdk error: cannot link with dpdk in $DPDK_LIB_DIR]) fi +fi - BUILD_WITH_DPDK_CFLAGS+="-fPIC -I$DPDK_INCLUDE" - if test "x$LOCAL_DPDK_INSTALL" != "xtrue" - then +# +# Note: An issue on Ubuntu 14.04 necessitates the use of -Wl,--no-as-needed: +# If you try compile with the older linker, the dpdk symbols will be undefined. +# This workaround should be removed when no longer necessary. +# +if test "x$with_libdpdk" = "xyes" +then + BUILD_WITH_DPDK_CFLAGS+="-I$DPDK_INCLUDE" + if test "x$LOCAL_DPDK_INSTALL" != "xyes" + then BUILD_WITH_DPDK_LDFLAGS="-Wl,--no-as-needed" else BUILD_WITH_DPDK_LDFLAGS="-L$DPDK_LIB_DIR -Wl,--no-as-needed" fi - BUILD_WITH_DPDK_LIBS="-Wl,-ldpdk" AC_SUBST(BUILD_WITH_DPDK_CFLAGS) AC_SUBST(BUILD_WITH_DPDK_LDFLAGS) AC_SUBST(BUILD_WITH_DPDK_LIBS) diff --git a/src/dpdkstat.c b/src/dpdkstat.c index 733bb0bb..54946358 100644 --- a/src/dpdkstat.c +++ b/src/dpdkstat.c @@ -122,8 +122,6 @@ static int dpdk_shm_init(size_t size);
