mips编译器交叉编译openssl

 

1.下载源码：

git clone https://github.com/openssl/openssl.git

 

2. 配置生成Makefile

 

./config  no-asm shared --prefix=$(pwd)/__install CROSS_COMPILE=mipsel-linux-

去掉Makefile中的 -m64

 

3 交叉编译

make

出现while loading shared libraries: libmpfr.so.4: cannot open shared object file:错误

原因是由于没有找到libmpfr.so.4,但是其实工具链是有该库的

解决方法手动指定库路径：export LD_LIBRARY_PATH=/root/buildroot-gcc464/usr/lib

 

再次make

./libcrypto.so: warning: gethostbyname is obsolescent, use getnameinfo() instead.
./libcrypto.so: undefined reference to getcontext' ./libcrypto.so: undefined reference tosetcontext'
./libcrypto.so: undefined reference to `makecontext'

主要的原因是uclibc 本身这不支持这些接口

解决方法如下：

make clean

./config  no-asm  no-async shared --prefix=$(pwd)/__install CROSS_COMPILE=mipsel-linux-

去掉Makefile 中的 -m64

make &&  make install  编译通过。
