64位ubuntu系统编译32位openssl

 

setarch i386 ./config -m32 --prefix=/*****

make

make install

--------------------------

交叉编译mips32：

./Configure linux-mips32 no-asm shared no-async --prefix=/home/qwertyu/openssl_crosscompile CROSS_COMPILE=/home/qwertyu/Downloads/buildroot-2020.08.1/output/host/bin/mipsel-linux- CC=gcc
