Hi everybody
I'm new to Crypto++, using version 5.1 with MSVC 6 and Windows NT.
Here is the deal :
- the lib compiles perfectly, no warning, and cryptest as well.
- I tried it in a little program (not using MFC) just to encrypt a string
using AES : OK.
- I have a big application, with the main project using MFC. When I insert
the lines :
#include "../cryptopp/modes.h"
#include "../cryptopp/aes.h"
using namespace CryptoPP;
in a file within this project, I get a lot of warnings and a compiler
internal error.
Here are the first warnings (in fact I get many more):
c:\atgl40\microsoft visual studio\v60\vc98\include\xmemory(39) : warning
C4100: '_P' : unreferenced formal parameter
c:\atgl40\microsoft visual studio\v60\vc98\include\xmemory(41) : warning
C4100: '_P' : unreferenced formal parameter
c:\atgl40\microsoft visual studio\v60\vc98\include\xlocale(296) : warning
C4663: C++ language change: to explicitly specialize class template
'codecvt' use the following syntax:
template<> class codecvt<unsigned short,char,int> ...
c:\atgl40\microsoft visual studio\v60\vc98\include\xlocale(387) : warning
C4018: '<' : signed/unsigned mismatch
c:\atgl40\microsoft visual studio\v60\vc98\include\xlocale(519) : warning
C4663: C++ language change: to explicitly specialize class template 'ctype'
use the following syntax:
template<> class ctype<char> ...
c:\atgl40\microsoft visual studio\v60\vc98\include\xlocale(552) : warning
C4100: '_D' : unreferenced formal parameter
c:\atgl40\microsoft visual studio\v60\vc98\include\xlocale(554) : warning
C4100: '_D' : unreferenced formal parameter
And here is is the fatal error :
c:\2kan\cryptopp\simple.h(14) : fatal error C1001: INTERNAL COMPILER ERROR
(compiler file 'msc1.cpp', line 1794)
- So I tried to insert a new project, not using MFC, in the workspace.
I put the little function that had worked the first time in it :
*********************************************************************
#include "../../cryptopp/modes.h"
#include "../../cryptopp/aes.h"
using namespace CryptoPP;
int TestCrypto()
{
byte key[AES::DEFAULT_KEYLENGTH], iv[AES::BLOCKSIZE];
// initialize key and iv here
CFB_Mode<AES >::Encryption cfbEncryption(key, AES::DEFAULT_KEYLENGTH,
iv);
byte plaintext[100], plaintext2[100], ciphertext[100];
// put data into plaintext here
// encrypt
cfbEncryption.ProcessData(ciphertext, plaintext, 100);
// now decrypt
CFB_Mode<AES >::Decryption cfbDecryption(key, 16, iv);
cfbDecryption.ProcessData(plaintext2, ciphertext, 100);
return 0;
}
*********************************************************************
This new project compiles well into a lib. But when I compile the main one
(with an include to a .h describing this function), I get this link error
message :
Linking...
Creating library .\Debug/Tai.lib and object .\Debug/Tai.exp
cipher.obj : error LNK2001: unresolved external symbol "int __cdecl
TestCrypto(void)" (?TestCrypto@@YAHXZ)
.\Debug/Tai.exe : fatal error LNK1120: 1 unresolved externals
Error executing link.exe.
I really don't know what to try now..
I tried a few tricks involving precompiled headers, but I don't really know
how those things work.
Any idea welcome ! I would really appreciate using Crypto++.
Thanx in advance !
