问题描述

我用 Openssl 用 C 和 C++ 编写了简单的应用程序.我是这样编译的:

I wrote simple apps with Openssl in C and C++. I compile them like this:

gcc openssltest.c -o openssltest -lcrypto
g++ openssltest.cpp -o openssltest -lcrypto

一切正常，但前提是你安装了 Openssl.

And its all ok but only, when you have Openssl installed.

我想编译它，以便我可以在没有 Openssl installend(类似 linux 的操作系统)的操作系统上运行它们.我试过这个:

I would like to compile it that I can run them on OS where theres no Openssl installend (linux-like OS). I tried this:

gcc -c openssltest.c -lcrypto -static
gcc openssltest.o -o openssltest -lcrypto -static

和 C++ 一样:

g++ -c openssltest.cpp -lcrypto -static
g++ openssltest.o -o openssltest -lcrypto -static

但是有这些错误:

我怎样才能做到这一点?我记得不久前我做了这个，但现在，呃，忘记了怎么做.我使用的是 Ubuntu 13.04 x64 - 会不会有问题?

How can I make this? I remember that a while ago I did this but now, erm, forgot how to do it. Im on Ubuntu 13.04 x64 - can it be an issue?
