首先交叉编译openssl。
将openssl/lib下面的文件拷贝到交叉编译器如下目录
/home/ctools/gcc-linaro-arm-linux-gnueabihf-4.9-2014.09_linux/arm-linux-gnueabihf/libc/usr/lib/arm-linux-gnueabihf
将openssl/include下面的openssl文件夹拷贝到交叉编译器如下目录
/home/ctools/gcc-linaro-arm-linux-gnueabihf-4.9-2014.09_linux/arm-linux-gnueabihf/libc/usr/include$
config.armlinux文件如下：
CROSS_COMPILE?= /home/ctools/gcc-linaro-arm-linux-gnueabihf-4.9-2014.09_linux/bin/arm-linux-gnueabihf-
COMPILE_OPTS = $(INCLUDES) -I/usr/local/include -I. -O2 -DSOCKLEN_T=socklen_t -DNO_SSTREAM=1 -D_LARGEFILE_SOURCE=1 -D_FILE_OFFSET_BITS=64
C = c
C_COMPILER = $(CROSS_COMPILE)gcc
C_FLAGS = $(COMPILE_OPTS)
CPP = cpp
CPLUSPLUS_COMPILER = $(CROSS_COMPILE)g++
CPLUSPLUS_FLAGS = $(COMPILE_OPTS) -Wall -DBSD=1

LIBRARY_LINK = $(CROSS_COMPILE)ar cr
LIBRARY_LINK_OPTS = $(LINK_OPTS)
LIB_SUFFIX = a
LIBS_FOR_CONSOLE_APPLICATION = -lssl -lcrypto
LIBS_FOR_GUI_APPLICATION =

PREFIX = /opt/live555/arm
其中PREFIX 指明了安装路径。
