libssl 版本 0.9.8e 与 0.9.7a 兼容吗?

发布于 2024-08-08 15:08:18 字数 2767 浏览 7 评论 0原文

我在我的 C++ 项目中使用第三方静态库,该库依赖于 libssl 版本 0.9.7a。由于各种原因,我的项目使用的libssl版本是0.9.8e。

一切都工作正常,直到第三方最近对其静态库进行了更改。当我的应用程序包含这个新版本的静态库时,我无法成功编译它。旧版本编译得很好。

我不太熟悉这些库依赖项及其向后兼容性。我们被告知必须使用第三方建议的版本。我只是想知道这是否真的是原因。 IMO,我想它应该向后兼容,不是吗?

非常感谢任何有关解决此问题的指导。

以下是我收到的编译错误:

错误消息表明不存在 opensslconf-i386.h 这样的文件,但它确实存在。

知道出了什么问题吗?

感谢您抽出时间!

I'm using a third party static library in my C++ project that has a dependency on libssl version 0.9.7a. Due to various reasons, the libssl version that my project used is 0.9.8e.

Everything was working fine, until the third party made a recent change to their static library. I wasn't able to successfully compile my application when it included this new version of the static library. The old version compiles fine.

I'm not very familiar with these library dependencies and their backwards compatibility. We were told that we must use the version suggested by the third party. I just want to know if that is really the reason. IMO, I guess it should be backwards compatible, shouldn't it?

Any direction with troubleshooting this issue is very much appreciated.

The following is the compilation error that I'm getting:

cc1plus: note: obsolete option -I- used, please use -iquote instead

The error message says that there's no such file as opensslconf-i386.h, but it is indeed present.

Any idea what's going wrong?

Thanks for you time!

C 预处理器找不到 opensslconf-i386.h 文件 - 因此您需要找出失败的原因。您收到编译器关于使用过时选项的警告(并且建议修复) - 执行它。

好的 - 你说文件存在:它在哪里,它的权限是什么?它是如何包含在 opensslconf.h 中的?该行与包含的任何其他 OpenSSL 标头有何不同。除了已弃用的“-I-”之外,您还使用哪些“-I”选项?

在这个阶段,我想说你要么安装错误,要么命令行奇怪。

而且问题标题……与问题正文没有明显关系。

  • 在操作层面上,是的,两者在大多数情况下可以相互作用。
  • 在编译级别,是的,两者基本上是兼容的(在 0.9.7a 中工作的应该也可以在 0.9.8e 中工作)。
  • 在内部和配置层面,会有细微的差别;例如,较新的版本可能支持额外的密码或模式。

The C pre-processor is not finding the opensslconf-i386.h file - so you need to find out why that is failing. You've got a warning from the compiler about using an obsolete option (and it recommends a fix) - do it.

OK - you say the file is present: where is it, and what are the permissions on it? How is it included by opensslconf.h? How is that line different from any other OpenSSL headers that are included. What are the '-I' options you are using other than the deprecated '-I-'?

At this stage, I'd say you've got either a faulty installation or an odd-ball command line.

And the question title is ... not obviously related to the question body.

  • At the operational level, yes, the two interwork for most purposes.
  • At the compilation level, yes, the two are basically compatible (that which worked in 0.9.7a should work with 0.9.8e).
  • At the internals and configuration level, there will be small differences; there may be extra ciphers or modes supported by the more recent version, for example.
