SSL v2未定義符號，Manjaro和Ubuntu

我要報告一個相當複雜的問題。SSL v2未定義符號，Manjaro和Ubuntu

我想開發一個跨平臺的python軟件。我在Manjaro Linux上，這是一個基於Arch-linux的發行版。

該軟件與cx_freeze一起打包，以方便其分發。所有必需的庫都捆綁在軟件包中，用戶只需執行一個二進制文件即可啓動該程序。在曼佳羅，二進制運行良好。

然而，當我嘗試在Ubuntu上，我遇到一個奇怪的問題：

有點挖後，似乎OpenSSL是沒有內置的支持2.0版本，在Ubuntu。我不明白的是程序崩潰的原因：由於所有的庫都與我的程序一起打包並交付，因此它不應該調用任何系統庫。

總之，我不明白爲什麼我的程序崩潰。任何幫助將不勝感激。

編輯：

在Ubuntu功能的版本2安裝OpenSSL時後，它完美的作品。但是這個程序很長很難，我不能要求我的未來用戶這樣做。所以，我應該構建Python 3不支持SSL V2的

「...因爲所有的庫都打包並與我的程序一起交付，它不應該調用任何系統庫......」 - 你確定像libc，libssl等操作系統庫真的包含在你發貨，即不僅是python庫？這將是非常罕見的。 –

你說得對，他們不是，因爲修補openssl解決了我的問題。我仍然在爲我的用戶尋求更簡單的解決方案。 – Rififi

您可以通過PIP卸載M2Crypto，然後安裝包python-m2crypto解決這個問題，然後確保安裝M2Crypto再次

pip uninstall M2Crypto 
apt-get install python-m2crypto 
pip install M2Crypto

這對我解決
