From 4b6f552a070b378fb12b07756f1df35db745598b Mon Sep 17 00:00:00 2001 From: Luca Ceresoli Date: Mon, 18 Feb 2013 09:39:32 +0000 Subject: [PATCH] qt: disable precompiled headers to workaround compilation failure Precompiled header implementation is buggy in current Qt as described at http://comments.gmane.org/gmane.comp.lib.qt.devel/5933. The only known workaround is currently to add -no-pch to configure. Fixes build failure terminating with error compiling ../3rdparty/pixman/pixman-arm-neon-asm.S cc1: fatal error: .pch/release-shared-emb-arm/QtGui: No such file or directory compilation terminated. such as: http://autobuild.buildroot.net/results/648265012591280fa592a239f86ee39aec2d5fa6/build-end.log Signed-off-by: Luca Ceresoli Signed-off-by: Peter Korsgaard --- package/qt/qt.mk | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/package/qt/qt.mk b/package/qt/qt.mk index ee1a88b7ac..9f50f9135d 100644 --- a/package/qt/qt.mk +++ b/package/qt/qt.mk @@ -416,10 +416,10 @@ else QT_CONFIGURE_OPTS += -no-declarative endif -# ccache and precompiled headers don't play well together -ifeq ($(BR2_CCACHE),y) +# -no-pch is needed to workaround the issue described at +# http://comments.gmane.org/gmane.comp.lib.qt.devel/5933. +# In addition, ccache and precompiled headers don't play well together QT_CONFIGURE_OPTS += -no-pch -endif # x86x86fix # Workaround Qt Embedded bug when crosscompiling for x86 under x86 with linux -- 2.30.2
