From: Florian Forster Date: Sat, 2 Dec 2006 18:11:22 +0000 (+0100) Subject: dns plugin: Improved config checks for the pthread library. X-Git-Tag: collectd-3.11.0~39^2 X-Git-Url: https://git.verplant.org/?a=commitdiff_plain;h=c4377c1e3d97ae0641bf740dc90a59633b319fd1;p=collectd.git dns plugin: Improved config checks for the pthread library. The checks for the pthread-library have been extended to match the other libraries being used. The dns plugin (in particular `utils_dns.c') has been verified to build without `libpcap' being present. --- diff --git a/configure.in b/configure.in index 348552ec..69c6aa91 100644 --- a/configure.in +++ b/configure.in @@ -276,9 +276,13 @@ AC_CHECK_HEADERS(stdarg.h) AC_CHECK_HEADERS(regex.h) # For the dns plugin +AC_CHECK_HEADERS(arpa/nameser.h arpa/nameser_compat.h) AC_CHECK_HEADERS(arpa/nameser.h) -AC_CHECK_HEADERS(pthread.h) + +AC_CHECK_HEADERS(net/if_arp.h) AC_CHECK_HEADERS(net/if_ppp.h) +AC_CHECK_HEADERS(netinet/if_ether.h) +AC_CHECK_HEADERS(netinet/udp.h) dnl Checking for libraries AC_CHECK_LIB(m, ext) @@ -497,24 +501,28 @@ AC_DEFINE_UNQUOTED(COLLECT_RRDTOOL, [$collect_rrdtool], [Wether or not to use rrdtool library]) AM_CONDITIONAL(BUILD_WITH_RRDTOOL, test "x$with_rrdtool" = "xyes") -with_pthread="yes" -AC_ARG_WITH(pthread, [AS_HELP_STRING([--with-pthread=@<:@=PREFIX@:>@], [Path to pthread (experimental).])], -[ if test "x$withval" != "xno" && test "x$withval" != "xyes" +AC_ARG_WITH(libpthread, [AS_HELP_STRING([--with-libpthread=@<:@=PREFIX@:>@], [Path to libpthread.])], +[ if test "x$withval" != "xno" -a "x$withval" != "xyes" then LDFLAGS="$LDFLAGS -L$withval/lib" CPPFLAGS="$CPPFLAGS -I$withval/include" - with_pthread="yes" + with_libpthread="yes" + else + if test "x$withval" = "xno" + then + with_libpthread="no (disabled)" + fi fi -], [with_pthread="no"]) -if test "x$with_pthread" = "xyes" +], [with_libpthread="no"]) +if test "x$with_libpthread" = "xyes" then - AC_CHECK_LIB(pthread, pthread_create, [with_pthread="yes"], [with_pthread="no (libpthread not found)"], []) + AC_CHECK_LIB(pthread, pthread_create, [with_libpthread="yes"], [with_libpthread="no (libpthread not found)"], []) fi -if test "x$with_pthread" = "xyes" +if test "x$with_libpthread" = "xyes" then - AC_CHECK_HEADERS(pthread.h,, [with_pthread="no (pthread.h not found)"]) + AC_CHECK_HEADERS(pthread.h,, [with_libpthread="no (pthread.h not found)"]) fi -if test "x$with_pthread" = "xyes" +if test "x$with_libpthread" = "xyes" then collect_pthread=1 else @@ -522,7 +530,7 @@ else fi AC_DEFINE_UNQUOTED(HAVE_LIBPTHREAD, [$collect_pthread], [Wether or not to use pthread (POSIX threads) library]) -AM_CONDITIONAL(BUILD_WITH_LIBPTHREAD, test "x$with_pthread" = "xyes") +AM_CONDITIONAL(BUILD_WITH_LIBPTHREAD, test "x$with_libpthread" = "xyes") if test "$ac_system" = "Solaris" then @@ -1003,6 +1011,7 @@ Configuration: libkstat . . . . . $with_kstat libmysql . . . . . $with_libmysql libpcap . . . . . . $with_libpcap + libpthread . . . . $with_libpthread Features: debug . . . . . . . $enable_debug diff --git a/src/dns.c b/src/dns.c index 61b5a1bd..b2039a72 100644 --- a/src/dns.c +++ b/src/dns.c @@ -25,30 +25,23 @@ #include "plugin.h" #include "configfile.h" #include "utils_debug.h" - -#if HAVE_PTHREAD_H -# include -#endif - -#if HAVE_SYS_POLL_H -# include -#endif +#include "utils_dns.h" #define MODULE_NAME "dns" -#if HAVE_LIBPCAP -# define NAMED_HAVE_CONFIG 1 -#else -# define NAMED_HAVE_CONFIG 0 -#endif - -#if HAVE_LIBPCAP && HAVE_PTHREAD_H -# include "utils_dns.h" -# define NAMED_HAVE_READ 1 +#if HAVE_LIBPCAP && HAVE_LIBPTHREAD +# include +# include +# include +# define DNS_HAVE_READ 1 #else -# define NAMED_HAVE_READ 0 +# define DNS_HAVE_READ 0 #endif +/* + * Private data types + */ +#if DNS_HAVE_READ struct counter_list_s { unsigned int key;
