Question

我有一个我试图运行的二进制文件，似乎特别需要OPENSSL_1.0.0版本4：

Version needs section '.gnu.version_r' contains 2 entries:
 Addr: 0x00000000080486ac  Offset: 0x0006ac  Link: 6 (.dynstr)
  000000: Version: 1  File: libcrypto.so.1.0.0  Cnt: 1
  0x0010:   Name: OPENSSL_1.0.0  Flags: none  Version: 4

我已经检查了openssl git中的源代码并构建了1.0.0-stable，但无法弄清楚如何专门构建二进制文件所需的内容。

我应该从openssl repo中查看哪个版本，如何编译它以便它可以被这个二进制文件使用？

以下是其精灵标题的其他可能的相关字段：

您看到的版本不是库的版本，而是表中符号的（任意）版本。正如jww已经指出的那样，它引用了OPENSSL_1.0.0这是符号版本字符串，并且与1.0.x版本分支有关。

请参阅https://blog.flameeyes.eu/2011/06/gold-readiness-obstacle-2-base-versioning/，了解我之前撰写的关于符号版本控制的随机引用。
