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 $(PROJECT_BUILD_DIR) More patches will be needed later to ensure all configurable packages are built in this directory. --- target/cloop/cloop.mk | 9 +++++---- 1 file changed, 5 insertions(+), 4 deletions(-) (limited to 'target/cloop') diff --git a/target/cloop/cloop.mk b/target/cloop/cloop.mk index ca6d8bd4a..bba984edb 100644 --- a/target/cloop/cloop.mk +++ b/target/cloop/cloop.mk @@ -15,6 +15,7 @@ CLOOP_DIR=$(BUILD_DIR)/cloop-$(CLOOP_VERSION) CLOOP_SOURCE=cloop_$(CLOOP_VERSION)-5.tar.gz CLOOP_SITE=http://developer.linuxtag.net/knoppix/sources +CLOOP_TARGET:=$(IMAGE).cloop ### Note: not used yet! ck ### $(DL_DIR)/$(CLOOP_PATCH1): ### $(WGET) -P $(DL_DIR) $(CLOOP_PATCH1_URL)/$(CLOOP_PATCH1) @@ -78,19 +79,19 @@ clooproot: cloop check-tools $(IMAGE).cramfs ### cramfsroot @rm -rf $(TARGET_DIR)/usr/share/man @rm -rf $(TARGET_DIR)/usr/info @rmdir -p --ignore-fail-on-non-empty $(TARGET_DIR)/usr/share - ### $(CLOOP_DIR)/create_compressed_fs -q -D target/default/device_table.txt $(TARGET_DIR) $(IMAGE).cloop - ## mkisofs -r $(TARGET_DIR) | $(CLOOP_DIR)/create_compressed_fs - 65536 > $(IMAGE).cloop + ### $(CLOOP_DIR)/create_compressed_fs -q -D target/default/device_table.txt $(TARGET_DIR) $(CLOOP_TARGET) + ## mkisofs -r $(TARGET_DIR) | $(CLOOP_DIR)/create_compressed_fs - 65536 > $(CLOOP_TARGET) sudo /sbin/losetup -d /dev/loop1 sudo /sbin/losetup /dev/loop1 $(IMAGE).cramfs sudo mkdir -p /mnt/compressed sudo mount -o ro -t cramfs /dev/loop1 /mnt/compressed - mkisofs -r /mnt/compressed | $(CLOOP_DIR)/create_compressed_fs - 65536 > $(IMAGE).cloop + mkisofs -r /mnt/compressed | $(CLOOP_DIR)/create_compressed_fs - 65536 > $(CLOOP_TARGET) - symlinks -r /mnt/compressed sudo umount /mnt/compressed @echo "Mounting a compressed image:" @echo " sudo mkdir -p /mnt/compressed" @echo " sudo /sbin/insmod cloop" - @echo " sudo /sbin/losetup /dev/cloop1 $(IMAGE).cloop" + @echo " sudo /sbin/losetup /dev/cloop1 $(CLOOP_TARGET)" @echo " sudo mount -o ro -t iso9660 /dev/cloop1 /mnt/compressed" clooproot-source: cloop-source -- cgit v1.2.3
