From 412ca2a4d4072b5d4d2fa819d62f6a8848ff7fda Mon Sep 17 00:00:00 2001 From: Ulf Samuelsson Date: Thu, 12 Jul 2007 13:11:03 +0000 Subject: BSP Patch: ========================================================= The purpose of the BSP patch is to allow building several boards inside the same buildroot tree. For this to work, each board has to have its own "$(TARGET_DIR)" and all *configurable* packages must be rebuilt for each board. They are now built in the "$(PROJECT_BUILD_DIR)" All non configurable packages can and should still be built in the "$(BUILD_DIR)". If a package is built for one board, then when you build for a second board of the same architecture the build becomes a simple copy of the resulting binaries. ----- Define BR2_PROJECT which will be used as the selector between different boards. Note that BR2_PROJECT allow you to build multiple root file systems for a single board, and should not be confused with BR2_BOARD_NAME which relates to the H/W. ----- Define PROJECT_BUILD_DIR as "PROJECT_BUILD_DIR/$(PROJECT)" Define BINARIES_DIR as "binaries/$(PROJECT)" Define TARGET_DIR as "$(PROJECT_BUILD_DIR)/root" (some prefix/postfix may apply) Resulting images are stored in "$(BINARIES_DIR)" ----- Define a few new environment variables in Makefile PROJECT: Stripped BR2_PROJECT DATE: Date of build in YYYY-MM-DD format HOSTNAME: Stripped BR2_HOSTNAME => /etc/hostname BANNER: Stripped BR2_BANNER => /etc/issue Linux and Busybox will be built in $(PROJECT_BUILD_DIR) More patches will be needed later to ensure all configurable packages are built in this directory. --- target/linux/Makefile.in | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'target/linux/Makefile.in') diff --git a/target/linux/Makefile.in b/target/linux/Makefile.in index 18c98b4c2..619b5706b 100644 --- a/target/linux/Makefile.in +++ b/target/linux/Makefile.in @@ -58,7 +58,7 @@ endif LINUX26_KERNEL=linux-kernel-$(LINUX26_VERSION)-$(KERNEL_ARCH) # Version of Linux AFTER patches -LINUX26_DIR=$(BUILD_DIR)/linux-$(LINUX26_VERSION) +LINUX26_DIR=$(PROJECT_BUILD_DIR)/linux-$(LINUX26_VERSION) # for packages that need it LINUX_VERSION:=$(LINUX_VERSION) @@ -89,10 +89,10 @@ $(DL_DIR)/$(LINUX26_SOURCE): $(LINUX26_DIR)/.unpacked: $(DL_DIR)/$(LINUX26_SOURCE) rm -rf $(LINUX26_DIR) - $(LINUX26_BZCAT) $(DL_DIR)/$(LINUX26_SOURCE) | tar -C $(BUILD_DIR) $(TAR_OPTIONS) - + $(LINUX26_BZCAT) $(DL_DIR)/$(LINUX26_SOURCE) | tar -C $(PROJECT_BUILD_DIR) $(TAR_OPTIONS) - ifneq ($(DOWNLOAD_LINUX26_VERSION),$(LINUX26_VERSION)) # Rename the dir from the downloaded version to the AFTER patch version - mv -f $(BUILD_DIR)/linux-$(DOWNLOAD_LINUX26_VERSION) $(LINUX26_DIR) + mv -f $(PROJECT_BUILD_DIR)/linux-$(DOWNLOAD_LINUX26_VERSION) $(LINUX26_DIR) endif touch $@ -- cgit v1.2.3
