From c2ea056a1b34fd1354100d08e603b9374e225968 Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Sat, 20 Oct 2018 15:25:35 +0200 Subject: [PATCH] package/qt5/qt5base: use ccache for building host code qt5 currently doesn't use HOSTCC/HOSTCXX, so it doesn't use ccache when building all its host code (especially qmake). This means that even with ccache enabled and a hot cache, it still takes a long time to build qt5base. Before this patch, building qt5base takes: - 446 seconds with a cold ccache - 185 seconds with a hot ccache This is because the ccache is not used for host code. After this patch, building qt5base takes: - 450 seconds with a cold ccache - 15 seconds with a hot ccache Signed-off-by: Thomas Petazzoni Reviewed-by: Peter Seiderer Signed-off-by: Thomas Petazzoni --- package/qt5/qt5base/qt5base.mk | 8 ++++++++ 1 file changed, 8 insertions(+) diff --git a/package/qt5/qt5base/qt5base.mk b/package/qt5/qt5base/qt5base.mk index 2b6fd39267..ec3d7042f1 100644 --- a/package/qt5/qt5base/qt5base.mk +++ b/package/qt5/qt5base/qt5base.mk @@ -271,6 +271,13 @@ define QT5BASE_CONFIGURE_ARCH_CONFIG endef endif +# This allows to use ccache when available +define QT5BASE_CONFIGURE_HOSTCC + $(SED) 's,^QMAKE_COMPILER\s*=.*,QMAKE_COMPILER=$(HOSTCC),' $(@D)/mkspecs/common/g++-base.conf + $(SED) 's,^QMAKE_CC\s*=.*,QMAKE_CC=$(HOSTCC),' $(@D)/mkspecs/common/g++-base.conf + $(SED) 's,^QMAKE_CXX\s*=.*,QMAKE_CXX=$(HOSTCXX),' $(@D)/mkspecs/common/g++-base.conf +endef + define QT5BASE_CONFIGURE_CMDS mkdir -p $(@D)/mkspecs/devices/linux-buildroot-g++/ sed 's/@EGLFS_DEVICE@/$(QT5BASE_EGLFS_DEVICE)/g' \ @@ -281,6 +288,7 @@ define QT5BASE_CONFIGURE_CMDS $(QT5BASE_CONFIGURE_CONFIG_FILE) touch $(QT5BASE_ARCH_CONFIG_FILE) $(QT5BASE_CONFIGURE_ARCH_CONFIG) + $(QT5BASE_CONFIGURE_HOSTCC) (cd $(@D); \ $(TARGET_MAKE_ENV) \ PKG_CONFIG="$(PKG_CONFIG_HOST_BINARY)" \ -- 2.30.2
