busybox(二)編譯

1. 解壓,原始碼包在busybox-1.7.0.tar.bz2,

   tar xjf  busybox-1.7.0.tar.bz2
   cd busybox-1.7.0/

2. 檢視說明文件INSTALL,注意不能直接使用make install,這樣會安裝到pc上,破壞pc.應該要使用make CONFIG_PREFIX=xxx目錄 install

    make menuconfig     # This creates a file called ".config"
    make                # This creates the "busybox" executable  
    make install        # or make CONFIG_PREFIX=/path/from/root install
    
   

3. 設定下交叉編譯工具為arm-linux-,修改頂層Makefile

   CROSS_COMPILE   ?=arm-linux-

4. 使用make menuconfig配置,發現提示錯誤,這是因為版本問題,修改下makefile

   [email protected]:/work/busybox-1.7.0$ make menuconfig
   Makefile:405: *** mixed implicit and normal rules: deprecated syntax
   Makefile:1242: *** mixed implicit and normal rules: deprecated syntax
   make: *** No rule to make target 'menuconfig'.  Stop.
    
   

   修改以下內容

   頂層Makefile 405行:config %config: scripts_basic outputmakefile FORCE 改為:
   %config: scripts_basic outputmakefile FORCE
   
   修改busybox-1.7.0 頂層Makefile 1242行:
   / %/: prepare scripts FORCE   改為:
   %/: prepare scripts FORCE
   
   如果還不行 
   要安裝 sudo apt-get install libncurses5-dev libncursesw5-dev 這兩個庫才可以

5. 修改配置專案,增加tab補全功能,busybox settings ---busybox libry tuning ----tab completion,輸入y選擇.其餘模組的使能一般在Linux Module Utilities --->

   中

6. make

7. 設定安裝路徑make CONFIG_PREFIX=~/stu/first_fs install

8. 可以看到檔案連結到busybox

   [email protected]:~/stu/first_fs$ ls -l
