Quagga 移植

一 Quagga 编译的依赖包

• libcares
• libncurses
• libreadline
  其中libreadline是需要libncurses支持的，如果没有ncurses,在编译quagga时会出现如下错误

   **/libreadline.so: undefined reference to `PC'
   **/libreadline.so: undefined reference to `tgetflag' 
   **/libreadline.so: undefined reference to `tgetent' 
   **/libreadline.so: undefined reference to `UP' 
   **/libreadline.so: undefined reference to `tputs' 
   **/libreadline.so: undefined reference to `tgoto' 
   **/libreadline.so: undefined reference to `tgetnum' 
   **/libreadline.so: undefined reference to `BC' 
   **/libreadline.so: undefined reference to `tgetstr'

二 先交叉编译三个依赖包

• libcares

  anzye@anzye:c-ares-1.15.0$ ./configure --host=arm-linux --prefix=/opt/arm_lib
  anzye@anzye:c-ares-1.15.0$ make && make install
  

• libncurses

  anzye@anzye:ncurses-6.1$ ./configure --host=arm-linux  --prefix=/opt/arm_lib --with-shared
  anzye@anzye:ncurses-6.1$ make && make install
  

• libreadline
  说明：如果是readline-6.3版 ，配置时要加上bash_cv_wcwidth_broken=yes一项,或注释掉configure中的对应报错项，否则报错。如下

  anzye@anzye:readline-6.3$ ./configure --host=arm-linux --prefix=/opt/arm_lib
  *** ***
  checking for wcwidth broken with unicode combining characters... 
  configure: error: in `/.../readline-6.3': configure: error: cannot run test program while cross compiling
  anzye@anzye:readline-6.3$ ./configure --host=arm-linux --prefix=/opt/arm_lib bash_cv_wcwidth_broken=yes
  anzye@anzye:readline-6.3$ make && make install
  

  or

  anzye@anzye:readline-7.0$ ./configure --host=arm-linux --prefix=/opt/arm_lib
  anzye@anzye:readline-7.0$ make && make install

三 编译Quagga

anzye@anzye:quagga-1.2.4$./configure \
	--prefix=`pwd`/install \
	--host=arm-linux \
	--disable-doc \
	--enable-static=no \
	--enable-user=root \
	--enable-group=root \
	--enable-vty-group=root \
	CFLAGS=-L/opt/arm_lib/lib \
	CPPFLAGS=-I/opt/arm_lib/include
anzye@anzye:c-ares-1.15.0$ make && make install

不指明“CFLAGS=-L/opt/arm_lib/lib\ CPPFLAGS=-I/opt/arm_lib/include”会报找不到头文件或库，因为上面编译安装的都在“/opt/arm_lib/”目录下
