Remove the "project" feature The "project" feature was designed to allow to several projects to be built inside the same Buildroot source tree and allowing the toolchain and non-configurable packages to be shared between the different projects on the same architecture. While being interesting in theory, this feature adds a level of complexity to Buildroot, both from an user perspective and from a developer perspective, while one of the main Buildroot strengh is to be simple. Moreover, this feature is only seldomly used by our users. From a user-level perspective, this for example allows to remove the project_build_ARCH directory, which was very confusing. The autotools-stamps directory is also removed, since these stamps are back at their normal location. Description of the changes involved : * project/, directory removed * Makefile - Don't include project/Makefile.in and project/project.mk anymore - Grab a copy of the contents of project/Makefile.in at the location it was imported, but remove the definition related to PROJECT_BUILD_DIR. The TARGET_DIR is now in $(BUILD_DIR)/target_dir - Remove the creation/removal of the $(PROJECT_BUILD_DIR) and $(PROJECT_BUILD_DIR)/autotools-stamps directories - Don't make world depends on target-host-info. This target was defined by project/project.mk to customize /etc/issue, /etc/hostname and create /etc/br-version depending on the project definitions. We can of course imagine re-adding such a feature later. - Replace PROJECT_BUILD_DIR by BUILD_DIR everywhere - Remove the update, log and lognr.$(PROJECT) target, they were specific to the project feature. * package/Makefile.autotools.in - Replace PROJECT_BUILD_DIR by BUILD_DIR for the location of the configure cache - Move the INSTALL_TARGET and HOOK_POST_INSTALL stamps to the same directory as the other stamps (i.e, in the package directory). * package/Makefile.in - Replace PROJECT_BUILD_DIR by BUILD_DIR for the location of the configure cache * package/at/at.mk, package/busybox/busybox.mk, package/busybox/initramfs.mk, package/customize/customize.mk, package/linux-fusion/linux-fusion.mk, package/ltp-testsuite/ltp-testsuite.mk, package/nfs-utils/nfs-utils.mk, target/cpio/cpioroot.mk, target/cramfs/cramfs.mk, target/device/Atmel/DataFlashBoot/DataflashBoot.mk, target/device/Atmel/Makefile.in, target/device/Atmel/at91bootstrap/at91bootstrap.mk, target/device/KwikByte/Makefile.in, target/ext2/ext2root.mk, target/initramfs/initramfs.mk, target/iso9660/iso9660.mk, target/jffs2/jffs2root.mk, target/linux/Makefile.in, target/romfs/romfs.mk, target/squashfs/squashfsroot.mk, target/tar/tarroot.mk, target/ubifs/ubifsroot.mk - Replace PROJECT_BUILD_DIR by BUILD_DIR * target/device/Config.in - Do not include project/Config.in anymore * target/linux/Makefile.in.advanced - Replace PROJECT_BUILD_DIR by BUILD_DIR - Store the stamps file in $(STAMP_DIR) instead of $(PROJECT_BUILD_DIR)/autotools-stamps * target/u-boot/Makefile.in - Replace PROJECT_BUILD_DIR by BUILD_DIR - Remove $(PROJECT) from the U-Boot target binary name - Remove the insertion in the configuration of the project name as the hostname - The u-boot-autoscript target now generates $(U_BOOT_AUTOSCRIPT).img instead of $(U_BOOT_AUTOSCRIPT).$(PROJECT) * toolchain/gcc/gcc-uclibc-3.x.mk toolchain/gcc/gcc-uclibc-4.x.mk - Move the stamps files to $(STAMP_DIR) Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

GCC_BUILD_DIR3:=$(BUILD_DIR)/gcc-$(GCC_VERSION)-target
Remove the "project" feature The "project" feature was designed to allow to several projects to be built inside the same Buildroot source tree and allowing the toolchain and non-configurable packages to be shared between the different projects on the same architecture. While being interesting in theory, this feature adds a level of complexity to Buildroot, both from an user perspective and from a developer perspective, while one of the main Buildroot strengh is to be simple. Moreover, this feature is only seldomly used by our users. From a user-level perspective, this for example allows to remove the project_build_ARCH directory, which was very confusing. The autotools-stamps directory is also removed, since these stamps are back at their normal location. Description of the changes involved : * project/, directory removed * Makefile - Don't include project/Makefile.in and project/project.mk anymore - Grab a copy of the contents of project/Makefile.in at the location it was imported, but remove the definition related to PROJECT_BUILD_DIR. The TARGET_DIR is now in $(BUILD_DIR)/target_dir - Remove the creation/removal of the $(PROJECT_BUILD_DIR) and $(PROJECT_BUILD_DIR)/autotools-stamps directories - Don't make world depends on target-host-info. This target was defined by project/project.mk to customize /etc/issue, /etc/hostname and create /etc/br-version depending on the project definitions. We can of course imagine re-adding such a feature later. - Replace PROJECT_BUILD_DIR by BUILD_DIR everywhere - Remove the update, log and lognr.$(PROJECT) target, they were specific to the project feature. * package/Makefile.autotools.in - Replace PROJECT_BUILD_DIR by BUILD_DIR for the location of the configure cache - Move the INSTALL_TARGET and HOOK_POST_INSTALL stamps to the same directory as the other stamps (i.e, in the package directory). * package/Makefile.in - Replace PROJECT_BUILD_DIR by BUILD_DIR for the location of the configure cache * package/at/at.mk, package/busybox/busybox.mk, package/busybox/initramfs.mk, package/customize/customize.mk, package/linux-fusion/linux-fusion.mk, package/ltp-testsuite/ltp-testsuite.mk, package/nfs-utils/nfs-utils.mk, target/cpio/cpioroot.mk, target/cramfs/cramfs.mk, target/device/Atmel/DataFlashBoot/DataflashBoot.mk, target/device/Atmel/Makefile.in, target/device/Atmel/at91bootstrap/at91bootstrap.mk, target/device/KwikByte/Makefile.in, target/ext2/ext2root.mk, target/initramfs/initramfs.mk, target/iso9660/iso9660.mk, target/jffs2/jffs2root.mk, target/linux/Makefile.in, target/romfs/romfs.mk, target/squashfs/squashfsroot.mk, target/tar/tarroot.mk, target/ubifs/ubifsroot.mk - Replace PROJECT_BUILD_DIR by BUILD_DIR * target/device/Config.in - Do not include project/Config.in anymore * target/linux/Makefile.in.advanced - Replace PROJECT_BUILD_DIR by BUILD_DIR - Store the stamps file in $(STAMP_DIR) instead of $(PROJECT_BUILD_DIR)/autotools-stamps * target/u-boot/Makefile.in - Replace PROJECT_BUILD_DIR by BUILD_DIR - Remove $(PROJECT) from the U-Boot target binary name - Remove the insertion in the configuration of the project name as the hostname - The u-boot-autoscript target now generates $(U_BOOT_AUTOSCRIPT).img instead of $(U_BOOT_AUTOSCRIPT).$(PROJECT) * toolchain/gcc/gcc-uclibc-3.x.mk toolchain/gcc/gcc-uclibc-4.x.mk - Move the stamps files to $(STAMP_DIR) Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
