Fix is also used in Debian: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=837393 [Peter: add comment explaining why] [Arnout: use host-cc-option to discover if -no-pie is available; cfr. 57b628a932b9b4a3c4bf80f4c82a81da5adcb173] Signed-off-by: Bernd Kuhls Signed-off-by: Peter Korsgaard Signed-off-by: Arnout Vandecappelle (Essensium/Mind) Signed-off-by: Thomas Petazzoni --- package/aespipe/aespipe.mk | 10 ++++++++++ 1 file changed, 10 insertions(+) diff --git a/package/aespipe/aespipe.mk b/package/aespipe/aespipe.mk index 6a38556ef1..5ef95d5206 100644 --- a/package/aespipe/aespipe.mk +++ b/package/aespipe/aespipe.mk @@ -9,5 +9,15 @@ AESPIPE_SOURCE = aespipe-v$(AESPIPE_VERSION).tar.bz2 AESPIPE_SITE = http://loop-aes.sourceforge.net/aespipe AESPIPE_LICENSE = GPL +# Recent Debian, Gentoo and Ubuntu enable -fPIE by default, breaking the build: +# https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=837393 +# https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=835148 +# Older gcc versions however don't support the -no-pie flag, so we have to +# check its availability. +HOST_AESPIPE_NO_PIE_FLAG = $(call host-cc-option,-no-pie) +HOST_AESPIPE_CONF_ENV = \ + CFLAGS="$(HOST_CFLAGS) $(HOST_AESPIPE_NO_PIE_FLAG)" \ + LDFLAGS="$(HOST_LDFLAGS) $(HOST_AESPIPE_NO_PIE_FLAG)" + $(eval $(autotools-package)) $(eval $(host-autotools-package))
