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 $(PROJECT_BUILD_DIR) More patches will be needed later to ensure all configurable packages are built in this directory. --- package/Makefile.in | 10 +++++++--- 1 file changed, 7 insertions(+), 3 deletions(-) (limited to 'package/Makefile.in') diff --git a/package/Makefile.in b/package/Makefile.in index 3cbf6321d..fc0f020b4 100644 --- a/package/Makefile.in +++ b/package/Makefile.in @@ -69,7 +69,11 @@ DL_DIR:=$(BASE_DIR)/dl endif #PATCH_DIR=$(BASE_DIR)/sources/patches BUILD_DIR:=$(BASE_DIR)/$(TOPDIR_PREFIX)build_$(ARCH)$(ARCH_FPU_SUFFIX)$(TOPDIR_SUFFIX) -TARGET_DIR:=$(BUILD_DIR)/root + +PROJECT_BUILD_DIR:=$(BASE_DIR)/$(TOPDIR_PREFIX)project_build_$(ARCH)$(ARCH_FPU_SUFFIX)$(TOPDIR_SUFFIX)/$(PROJECT) +BINARIES_DIR:=$(BASE_DIR)/binaries/$(PROJECT) +TARGET_DIR:=$(PROJECT_BUILD_DIR)/root + GNU_TARGET_SUFFIX:=-$(strip $(subst ",, $(BR2_GNU_TARGET_SUFFIX))) #")) @@ -81,7 +85,7 @@ TOOL_BUILD_DIR=$(BASE_DIR)/$(TOPDIR_PREFIX)toolchain_build_$(ARCH)$(ARCH_FPU_SUF # Quotes are needed for spaces et al in path components.
