使用OpenEmbedded構建交叉編譯環境 [轉]

使用OpenEmbedded構建交叉編譯環境      http://blog.csdn.net/leo_cao/archive/2007/08/06/1728122.aspx 1，選擇 /opt作爲存放openembedded的文件系統。 2，設置環境變量： export OEDIR=/opt/openembedded export PATH=$OEDIR/bitbake/bin:$PATH export BBPATH=$OEDIR/build:$OEDIR/org.openembedded.dev 3，創建 「/opt/openembedded」目錄，這是根 4，構建環境，先安裝軟件包，debian系統testing branch： http://www.openembedded.org/wiki/RequiredSoftware http://www.openembedded.org/wiki/OEandYourDistro 5，接下，獲取bitbake svn co svn://svn.berlios.de/bitbake/branches/bitbake-1.8/ bitbake 而後，安裝monotone 0.32版本，獲取OE的數據庫: wget http://www.openembedded.org/snapshots/OE.mtn.bz2 bunzip2 <OE.mtn.bz2 >OE.mtn 而後更新 mtn --db=OE.mtn db migrate mtn --db=OE.mtn pull monotone.openembedded.org org.openembedded.dev 而後獲取 openembedded的源代碼 mtn --db=OE.mtn checkout --branch=org.openembedded.dev 6，建立配置文件 cp org.openembedded.dev/conf/local.conf.sample build/conf/local.conf 修改後的格式： DL_DIR = "${OEDIR}/sources" BBFILES := "${OEDIR}/org.openembedded.dev/packages/*/*.bb" #BBMASK = "" # Select between multiple alternative providers, if more than one is eligible. PREFERRED_PROVIDERS = "virtual/qte:qte virtual/libqpe:libqpe-opie" PREFERRED_PROVIDERS += " virtual/libsdl:libsdl-x11" PREFERRED_PROVIDERS += " virtual/${TARGET_PREFIX}gcc-initial:gcc-cross-initial" PREFERRED_PROVIDERS += " virtual/${TARGET_PREFIX}gcc:gcc-cross" PREFERRED_PROVIDERS += " virtual/${TARGET_PREFIX}g++:gcc-cross" MACHINE = "qemuarm" TARGET_ARCH = "arm" TARGET_OS = "linux" DISTRO = "generic" MACHINE_KERNEL_VERSION = "2.6" IMAGE_FSTYPES = "jffs2 tar" BBDEBUG = "yes" # PARALLEL_MAKE = "-j 4" BBINCLUDELOGS = "yes" 7，得到交叉編譯工具鏈 bitbake gcc 8，使用交叉編譯工具 交叉編譯工具在tmp/cross/bin/下，能夠用它們編譯一個 hello, world。 9，運行編譯好的目標程序 這就須要用qemu這樣的模擬程序了，或者用開發板。
