C++ - Use CryptoPP

[nKnade]

Im trying to get it running since a while^^

I now added the Project "cryptlib" as Dependency and included the cryptlib.h
Also i set the Include Path.


But im getting these Errors if i try to create :

error LNK2001: Nicht aufgelöstes externes Symbol ""public: virtual void __thiscall CryptoPP::IteratedHashBase<unsigned int,class CryptoPP::HashTransformation>::Update(unsigned char const *,unsigned int)" (?Update@?$IteratedHashBase@IVHashTransformation@CryptoPP@@@CryptoPP@@UAEXPBEI@Z)".

Anyone knows the Solution?
Greetings :)

Looks like these are linker errors, you need to link the cryptopp library.  Not sure which OS but on linux for instance you would do soemthing like 

g++ myfile.cc -lcryrptopp 

(or crypto++ or whatever the library file is called :-) )

First Thanks for you Answer. Im working on Windows.

But do i still need the Lib if i include the Projekt of the Lib as Dependency?
Even if i include it the errors dont change :)

I imagine "Nicht aufgelöstes externes Symbol" means that the program is trying to locate code that's not implemented as it's in the library and it's not linked. 

In any case Wei and Jeff have a good page(s) here on these issues

Hope this helps
