嵌入式Linux之移植dhcp源码

1. tar xvzf dhcp-4.2.5-P1.tar.gz

2. ./configure --host=arm-linux ac_cv_file__dev_random=yes

3. vi bind/Makefile 

　　(cd ${bindsrcdir} && ./configure --disable-kqueue --disable-epoll --disable-devpoll --without-openssl --without-libxml2 --enable-exportlib --enable-threads=no --with-export-includedir=${binddir}/include --with-export-libdir=${binddir}/lib --with-gssapi=no > ${binddir}/configure.log);

　　修改为

　　(cd ${bindsrcdir} && ./configure BUILD_CC=gcc ac_cv_file__dev_random=yes --host=arm-linux --disable-kqueue --disable-epoll --disable-devpoll --without-openssl --without-libxml2 --enable-exportlib --enable-threads=no --with-export-includedir=${binddir}/include --with-export-libdir=${binddir}/lib --with-gssapi=no > ${binddir}/configure.log);

4. cd bind/

5. tar xvzf bind.tar.gz

6. vi bind-9.8.4-P2/lib/export/dns/Makefile.in

　　gen: ${srcdir}/gen.c
　　${CC} ${ALL_CFLAGS} ${LDFLAGS} -o $@ ${srcdir}/gen.c ${LIBS}

　　修改为

　　gen: ${srcdir}/gen.c
　　${BUILD_CC} ${ALL_CFLAGS} ${LDFLAGS} -o $@ ${srcdir}/gen.c ${LIBS}
