From: Stefan Hajnoczi <[email protected]> This patch makes builds --without-lttv-gui work by linking against libm.
Signed-off-by: Stefan Hajnoczi <[email protected]> --- This patch is my attempt to fix the following build issue: Building --without-lttv-gui produces linker errors due to missing libm. The build works fine when GUI is enabled. This issue happens with lttv-0.12.31-04072010 and lttv.git: $ ./configure --without-lttv-gui $ make /bin/bash ../../libtool --tag=CC --mode=link gcc -pthread -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -pthread -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -Wall -Wformat -g -O2 -export-dynamic -o lttv.real batchtest.o main.o module.o option.o hook.o attribute.o iattribute.o state.o stats.o tracecontext.o traceset.o filter.o print.o sync_chain.o sync_chain_lttv.o graph_functions.o data_structures.o event_processing_lttng_common.o event_processing_lttng_standard.o event_processing_lttng_null.o event_matching_broadcast.o event_matching_distributor.o event_matching_tcp.o event_analysis_chull.o event_analysis_eval.o event_analysis_linreg.o factor_reduction_accuracy.o -lpopt ../../ltt/liblttvtraceread.la -lpthread -pthread -lgobject-2.0 -lgthread-2.0 -lrt -lglib-2.0 -Wl,--export-dynamic -pthread -lgmodule-2.0 -lrt -lglib-2.0 libtool: link: gcc -pthread -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -pthread -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -Wall -Wformat -g -O2 -o .libs/lttv.real batchtest.o main.o module.o option.o hook.o attribute.o iattribute.o state.o stats.o tracecontext.o traceset.o filter.o print.o sync_chain.o sync_chain_lttv.o graph_functions.o data_structures.o event_processing_lttng_common.o event_processing_lttng_standard.o event_processing_lttng_null.o event_matching_broadcast.o event_matching_distributor.o event_matching_tcp.o event_analysis_chull.o event_analysis_eval.o event_analysis_linreg.o factor_reduction_accuracy.o -pthread -Wl,--export-dynamic -pthread -Wl,--export-dynamic /usr/lib/libpopt.so ../../ltt/.libs/liblttvtraceread.so -lpthread /usr/lib/libgobject-2.0.so /usr/lib/libgthread-2.0.so /usr/lib/libgmodule-2.0.so -lrt /usr/lib/libglib-2.0.so -pthread event_analysis_chull.o: In function `calculateFactorsMiddle': /tmp/lttv/lttv/lttv/sync/event_analysis_chull.c:987: undefined reference to `sqrt' event_analysis_eval.o: In function `printAnalysisStatsEval': /tmp/lttv/lttv/lttv/sync/event_analysis_eval.c:894: undefined reference to `sqrt' event_analysis_eval.o: In function `analyzeBroadcastEval': /tmp/lttv/lttv/lttv/sync/event_analysis_eval.c:751: undefined reference to `sqrt' event_analysis_eval.o: In function `binNum': /tmp/lttv/lttv/lttv/sync/event_analysis_eval.c:1311: undefined reference to `log' /tmp/lttv/lttv/lttv/sync/event_analysis_eval.c:1311: undefined reference to `log' /tmp/lttv/lttv/lttv/sync/event_analysis_eval.c:1311: undefined reference to `floor' event_analysis_eval.o: In function `binStart': /tmp/lttv/lttv/lttv/sync/event_analysis_eval.c:1343: undefined reference to `pow' event_analysis_eval.o: In function `binEnd': /tmp/lttv/lttv/lttv/sync/event_analysis_eval.c:1370: undefined reference to `pow' event_analysis_linreg.o: In function `finalizeLSA': /tmp/lttv/lttv/lttv/sync/event_analysis_linreg.c:317: undefined reference to `sqrt' collect2: ld returned 1 exit status make[4]: *** [lttv.real] Error 1 System info: Linux 2.6.32-3-amd64 autoconf (GNU Autoconf) 2.65 gcc (Debian 4.4.4-1) 4.4.4 GNU assembler (GNU Binutils for Debian) 2.20.1-system.20100303 configure.ac | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/configure.ac b/configure.ac index 69d3809..b3b86fb 100644 --- a/configure.ac +++ b/configure.ac @@ -156,7 +156,7 @@ fi pkg_modules="gobject-2.0 >= 2.0.0" PKG_CHECK_MODULES(GOBJECT, [$pkg_modules]) -LIBS="$LIBS $GTK_LIBS $GOBJECT_LIBS $GMODULE_LIBS" +LIBS="$LIBS $M_LIBS $GTK_LIBS $GOBJECT_LIBS $GMODULE_LIBS" PACKAGE_CFLAGS="$GTK_CFLAGS $GOBJECT_CFLAGS $GMODULE_CFLAGS -Wall -Wformat" MODULE_CFLAGS="$PACKAGE_CFLAGS -fvisibility=hidden" MODULE_LDFLAGS="-module -avoid-version" -- 1.7.1 _______________________________________________ ltt-dev mailing list [email protected] http://lists.casi.polymtl.ca/cgi-bin/mailman/listinfo/ltt-dev
