Re: 5.0.4/5.2.1 Source Compatibility

[Wei Dai]

This looks like a problem with project settings, rather than code 
compatibility. Are you able to compile the dlltest project that comes with 
Crypto++? If so, try making a copy of that project file and put your own 
code into it.

Subject: 5.0.4/5.2.1 Source Compatibility


Hi,
Is there a document somewhere that outlines the source level
incompatibilites between 5.0.4 (DLL) and 5.2.1 (DLL)? I'm getting 5.2.1
(.NET2003) link errors in a pretty basic example that workds in 5.0.4
(MSVC6).
Code:
 CFB_Mode<AES>::Encryption cfb(&aes_key[0], aes_key.size(),
                               iv_begin, feed_back_size);
 cfb.ProcessData(&ciphertext[0], data_begin, data_size);
<field types are generally simple: aes_key/ciphertext above are
std::vector<char> and data_begin is char*>
This links fine with the 5.0.4 DLL, but has the following link erros in
5.2.1:
