ac_cv_linux_vers=2.6.30.1 ac_cv_lib_crypto_DES_cbc_encrypt=no ./configure --prefix=/home/src/tcpdump/install --disable-FEATURE --host=arm-linux


configure 成功之后需要修改Makefile,不修改会造成编译器内部错误,或者汇编指令错误,当然都是误报的.就是将"/usr/include"和"/usr/lib"修改为我们的$(prefix)/include和$(prefix)/lib, 也就是我们安装libpcap的地方(以加粗):

      INCLS = -I. -I./../libpcap-1.0.0  -I$(prefix)/include -I$(srcdir)/missing
      DEFS = -DHAVE_CONFIG_H  -I./../libpcap-1.0.0  -I$(prefix)/include -I$(srcdir)/missing -D_U_="__attribute__((unused))"

      # Standard LDFLAGS
      LDFLAGS = -L$(prefix)/lib


      make && make install
