ssl - ARM 上基于 libpurple 的连接尝试错误 "SSL peer presented an invalid certificate"

Question

我正在使用 libpurple (libpurple.com) 开发聊天应用程序。 在 x86 处理器(台式机)上一切正常

但是，相同的代码在 ARM (iMx Freescale) 处理器上运行时显示错误:

“SSL peer 出示了无效证书”，同时登录。

我使用的是 Ubuntu 操作系统。就像在 x86 机器中一样，所有包似乎都适用于 ARM 处理器。 (包括 gnutls 开发包)

任何线索将不胜感激......

我已将问题发布到 pidgin 邮件列表:

Hi all, I am using libpurple (package- 1:2.10.0-0ubuntu2) for developing a chat application. Everything works fine on x86 processor (Desktop - Ubuntu 11.10)

However, the same chat application (after cross-compilation) when run on the ARM (iMx Freescale based on Ubuntu 11.10) processor shows error:

"SSL peer presented an invalid certificate", while logging in.

--1-- All the packages seems to be present for the ARM target just like in the x86 machine. (including gnutls dev package, as mentioned in FAQ http://developer.pidgin.im/wiki/Installing%20Pidgin#IhaveOpenSSLwhyisntPidginusingit).

--2-- I have installed the ca-certificates package (updated it to the newest one in the Ubuntu repository for Ubuntu 11.10), using: 'apt-get install ca-certificates'.

--3-- Also tried copying the contents of "~/.purple/certificates/x509/tls_peers/", from the properly working x86 machine to the target system.

The SSL error still persists after these. Any help in resolving this issue would be highly appreciated. Thanks & Regards, Roy

You could try to figure out why Pidgin thinks the certificate is invalid by running with "pidgin -d" to show lots of debug output (I'm a little surprised the error message you're seeing doesn't already say why it's invalid). The two most likely reasons I can think of are either the clock on your ARM computer is wrong, or Pidgin still can't find the CA certificates.

将目标 ARM 板上的日期更改为当前日期后，错误已解决!
