我用 C 和 C++ 使用 Openssl 编写了简单的应用程序。我像这样编译它们：

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

一切都好，但只有当你安装了 Openssl 时。

我想编译它，以便可以在没有 Openssl installend 的操作系统（类 linux 的操作系统）上运行它们。我试过这个：

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？我记得前段时间我这样做了，但是现在，呃，忘记了怎么做。我在 Ubuntu 13.04 x64上- 这可能是个问题吗？

我在尝试使用 openssl lib 静态编译一个简单的 DES 程序时遇到了类似的问题。我用过-lcrypto -lz -ldl -static-libgcc，它对我有用。没有警告或错误。

您需要知道库需要作为静态链接的 *.a 文件提供。如果不是，那么编译要么失败，要么你最终得到一个动态链接的可执行文件。

如果这得到太多 PITA（所有库依赖项都需要静态编译到，它们的依赖项也需要等等）使用buildroot之类的东西

修补程序：也尝试静态链接 libdl。

如果这不起作用，恕我直言，您的 libcrypto.a 编译错误。

我和你有同样的问题。这是为我解决它的命令：

gcc yourfile.c -o yourfile -static -lcrypto -lz -ldl

它会生成此警告：

/usr/lib/gcc/i686-linux-gnu/4.7/../../../i386-linux-gnu/libcrypto.a(dso_dlfcn.o): In function `dlfcn_globallookup': (.text+0x1b): warning: Using 'dlopen' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking

但可执行文件仍然有效。
