Question

我有一个我无法理解的问题。

首先，我正在制作使用Crypto ++ for RSA的程序。我已经分离了32位和64位mingw-w64的工具链。所以我下载了cryptopp源并为32位和64位构建了2次，并复制了lib和包含文件。我使用默认make ...

所以我编译了我的代码和静态库，当我在编译的机器上运行它时，32位和64位工作正常。但是当我将它复制到另一台机器XP 64bit或Win7 32bit时，它会在运行时崩溃。在Win7上我只使用32位，在XP上我使用32位和64位。

我正在搜索一段时间，发现它崩溃了这段代码：

StringSource ss1(message, true,
        new SignerFilter(rng, signer,
            new StringSink(signature)
       )
    );

但只运行它并没有崩溃。

new SignerFilter(rng, signer,
                new StringSink(signature)
           )

有没有人知道它会是什么？

这是我的测试代码

Answer 1

只是稍微环顾四周。我发现构建libcryptopp存在问题，只有几行代码修复了之前的症状。

以下是GNUmakefile中要更改的内容： https://sites.google.com/site/ievgensychov/cryptopp

是的，问题已经解决了。

在另一台机器崩溃（mingw-w64 32和64位工具链）cryptopp上运行已编译的代码
