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. --- project/Config.in | 26 ++++++++++++++++++++++++++ 1 file changed, 26 insertions(+) create mode 100644 project/Config.in (limited to 'project') diff --git a/project/Config.in b/project/Config.in new file mode 100644 index 000000000..67dd080e7 --- /dev/null +++ b/project/Config.in @@ -0,0 +1,26 @@ +menu "Project Options" + +config BR2_PROJECT + string "Project name" + default "uclibc" + help + The project name is used to define subdirectories + * where the Board Support Packages are built + (Linux,Root fs Bootmonitor,Utilities etc.) + * where the resulting binaries are stored. + Older targets may still build in the build_ + and store binaries in the top directory. + +config BR2_HOSTNAME + string "hostname" + default "uclibc" + help + The hostname string is stored in "/etc/hostname" + +config BR2_BANNER + string "banner" + default "Welcome to the Erik's uClibc development environment." + help + The banner string is stored in "/etc/issue" + +endmenu -- cgit v1.2.3
