Signature check with libgpgme-11.dll

[Knud Pehrs]

Hello!

I have a problem to use the functions of libgpgme-11.dll in my application.
I have downloaded the gnupg-1.4.10, libgpg-error-1.7 and gpg_MadeEasy_1.1.8.
All three packages were installed to c:\usr\local\bin
The gnupg-1.4.10 and libgpg-error-1.7 were build with ./configure, make, make install.
The gpg_MadeEasy_1.1.8 was configured with
./configure --prefix=/usr --enable-static --with-gpg=/usr/bin/gpg
--without-gpgsm --disable-largefile --without-pth-test
and build with make and make install.

To build the libraries I used MINGW32.
My operating system is WinXP and Visual Studio 2005 (C++).

I my application I load the libgpgme-11.dll via LoadLibrary(...).
If I start the app and init the GPGME I get always the same error 117440662 (invalid crypto engine)

Here is my initialization of GPGME:

        GPGSETLOCALE pSetLocale = (GPGSETLOCALE) GetProcAddress( hMod, "gpgme_set_locale" );
        if( pSetLocale != NULL )
        {
                GPGVERSIONCHK pVersionChk = (GPGVERSIONCHK) GetProcAddress( hMod, "gpgme_check_version" );
                if( pVersionChk != NULL )
                {
                        setlocale (LC_ALL, "");
                        pVersionChk( NULL ); // gpgme_check_version
                        pSetLocale( NULL, LC_CTYPE, setlocale( LC_CTYPE, NULL ) ); // gpgme_set_locale
                }
                               
        GPGSETENGINEINFO pSetEngineInfo =(GPGSETENGINEINFO)GetProcAddress( hMod, gpgme_set_engine_info" );
                if( pSetEngineInfo != NULL )
                {
               
                // ********   HERE OCCURS THE ERROR 117440662 (invalid crypto engine)    **********
                gpgme_error_t error = pSetEngineInfo( GPGME_PROTOCOL_OpenPGP, "gpg.exe", C:/usr/local/bin" );
                if( error != GPG_ERR_NO_ERROR) // gpgme_set_engine_info
                {
                        freeResult = FreeLibrary( hMod ); // free the DLL module
                        return false;
                }
        }

Have you any ideas how I can fix this error and what's the reason of this error is?

If you need more detailed information please let me know!

A soon answer would be appreciated!

Thank you very much and
best regards
