From bf6be9f5238a0db221089f87a601738a110bd4d6 Mon Sep 17 00:00:00 2001 From: Lada Trimasova Date: Tue, 26 Jan 2016 18:34:50 +0300 Subject: buildsys: fix static configuration and building In case of uClibc librt depends on libpthread. In particular timer_create() function uses pthread_XXX(). That means in case of static builds it's required to link not librt alone but together with libpthread. So if checking timer_create function in librt fails, it is necessary to check if timer_create function successfully links with "-lpthread". That issues was spotted in Buldroot autobuilder failures: http://autobuild.buildroot.net/results/759/75960db671807091fe9155aee9e46a6245e32590/ http://autobuild.buildroot.org/results/112/112e8b85783f5aaba42a937a6eb064317615a21b/ Signed-off-by: Lada Trimasova --- configure.ac | 9 ++++++++- 1 file changed, 8 insertions(+), 1 deletion(-) (limited to 'configure.ac') diff --git a/configure.ac b/configure.ac index 3002e77a2..75e869064 100644 --- a/configure.ac +++ b/configure.ac @@ -394,7 +394,14 @@ AC_CHECK_FUNCS([timer_create], [AC_CHECK_LIB([rt], [timer_create], [ have_timer="yes" REALTIME_LIBS="-lrt" - ])] + ],[ + AC_SEARCH_LIBS([timer_create], [rt], [ + AC_MSG_RESULT(yes) + have_timer="yes" + REALTIME_LIBS="-lrt -lpthread" + ],[], [-lpthread] + ) + ])] ) AC_SUBST([REALTIME_LIBS]) -- cgit v1.2.3-55-g7522
