From 2ca084ccaae619ac8031e902c66817d021ac6fd5 Mon Sep 17 00:00:00 2001 From: Roman Yeryomin Date: Fri, 12 Jun 2020 21:43:46 +0300 Subject: build: improve ccache support Set CCACHE_DIR to $(TOPDIR)/.ccache and CCACHE_BASEDIR to $(TOPDIR). This allows to do clean and dirclean. Cache hit rate for test build after dirclean is ~65%. If CCACHE is enabled stats are printed out at the end of building process. CCACHE_DIR config variable allows to override default, which could be useful when sharing cache with many builds. cacheclean make target allows to clean the cache. Changes from v1: - remove ccache directory using CCACHE_DIR variable - remove ccache leftovers from sdk and toolchain make files - introduce CONFIG_CCACHE_DIR variable - introduce cacheclean make target Signed-off-by: Roman Yeryomin --- target/sdk/Makefile | 8 ++------ 1 file changed, 2 insertions(+), 6 deletions(-) (limited to 'target/sdk') diff --git a/target/sdk/Makefile b/target/sdk/Makefile index 6d81834720..d3552b47eb 100644 --- a/target/sdk/Makefile +++ b/target/sdk/Makefile @@ -20,7 +20,7 @@ STAGING_SUBDIR_HOST := staging_dir/host STAGING_SUBDIR_TARGET := staging_dir/$(TARGET_DIR_NAME) STAGING_SUBDIR_TOOLCHAIN := staging_dir/toolchain-$(ARCH)$(ARCH_SUFFIX)_gcc-$(GCCV)_$(LIBC)$(if $(CONFIG_arm),_eabi) -EXCLUDE_DIRS:=*/ccache/* \ +EXCLUDE_DIRS:= \ */stamp \ */stampfiles \ */man \ @@ -135,11 +135,7 @@ $(BIN_DIR)/$(SDK_NAME).tar.xz: clean $(TOPDIR)/package/kernel/linux \ $(SDK_BUILD_DIR)/package/ - -rm -rf \ - $(SDK_BUILD_DIR)/$(STAGING_SUBDIR_HOST)/ccache \ - $(SDK_BUILD_DIR)/$(STAGING_SUBDIR_TARGET)/ccache \ - $(SDK_BUILD_DIR)/$(STAGING_SUBDIR_TOOLCHAIN)/ccache \ - $(SDK_BUILD_DIR)/$(STAGING_SUBDIR_HOST)/.prereq-build + -rm -rf $(SDK_BUILD_DIR)/$(STAGING_SUBDIR_HOST)/.prereq-build -rm -f $(SDK_BUILD_DIR)/feeds.conf.default $(if $(BASE_FEED),echo "$(BASE_FEED)" > $(SDK_BUILD_DIR)/feeds.conf.default) -- cgit v1.2.3
