手动编译OpenSSL:在创建共享库时不能使用符号；用-fPIC重新编译 [英] Manually compile OpenSSL: symbol can not be used when making a shared object; recompile with -fPIC

问题描述

我的OpenSSL似乎太旧了.而且没有地方可以解释如何安装最新的OpenSSL库.

My OpenSSL seems to be too old. And there's no place where they explain how to install a more recent OpenSSL library.

openssl version -a
OpenSSL 1.0.1t  3 May 2016
built on: Fri Mar 30 13:47:53 2018
platform: debian-amd64
options:  bn(64,64) rc4(16x,int) des(idx,cisc,16,int) blowfish(idx)

OPENSSLDIR: "/usr/lib/ssl"

当我想手动安装更新的OpenSSL库时，出现此错误:

When I want to manually install a more recent OpenSSL library, I get this error:

推荐答案

链接器错误:

/usr/bin/ld: libcrypto.a(rsaz_exp.o): relocation R_X86_64_32 against `.rodata' 
    can not be used when making a shared object; recompile with -fPIC

表示归档文件libcrypto.a中的目标文件rsaz_exp.o 尚未被编译为位置独立代码"，因此必须 链接到共享对象.建议您使用以下命令重新编译该目标文件 -fPIC.这意味着从源代码重建您的libcrypto.a -fPIC编译选项.

is saying that the object file rsaz_exp.o in the archive libcrypto.a has not been compiled as Position Independent Code, and it must be to be linked into a shared object. It suggests you recompile that object file with -fPIC. Which would mean rebuilding your libcrypto.a from source, with the -fPIC compilation option.

如果您不想这样做，请通过共享的libcrypto.so提供链接 代替链接.

If you don't want to do that, provide your linkage with a shared libcrypto.so to link against instead.
