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.
I have patched the gnupg-1.4.10 as described by Carlo Luciano Bianco.
The gpg_MadeEasy_1.1.8 was configured with ./configure --prefix=c:/usr/local
--enable-static --with-gpg=c:/usr/local --without-gpgsm and build with make and
make install.
To build the libraries I used MINGW32.
My operating system is WinXP and Visual Studio 2005 (C++).
In my application I load the libgpgme-11.dll via LoadLibrary(...).
I init GPGME like:
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 )
{
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;
}
}
I init CTX like:
// *** INIT CTX ***
GPGNEWDATA pNewData = (GPGNEWDATA) GetProcAddress( hMod, "gpgme_new" );
if( pNewData != NULL )
{
gpgme_error_t error = pNewData( &ctx );
if( error != GPG_ERR_NO_ERROR )
{
GPGRELDATA pRelData = (GPGRELDATA) GetProcAddress(
hMod, "gpgme_data_release" );
if( pRelData != NULL )
pRelData( keydata );
freeResult = FreeLibrary( hMod );
// free the DLL module
return false;
}
}
I read the public key file like:
GPGRead pRead = (GPGRead) GetProcAddress( hMod,
"gpgme_data_new_from_file" );
if( pRead != NULL )
{
err = pRead( &keydata, cipher_2_asc, 1 ); //
Method: gpgme_data_new_from_file
if( err != GPG_ERR_NO_ERROR )
{
// could not create a new data buffer
GPGRELDATA pRelData = (GPGRELDATA) GetProcAddress(
hMod, "gpgme_data_release" );
if( pRelData != NULL )
pRelData( keydata );
freeResult = FreeLibrary( hMod );
// free the DLL module
return false;
}
}
But if I import the public key file into the context CTX like following code I
get the error 117440662 (invalid crypto engine).
GPGIMPORT pImport = (GPGIMPORT) GetProcAddress( hMod, "gpgme_op_import"
);
if( pImport != NULL )
{
err = pImport( ctx, keydata );
// Method: gpgme_op_import
if( err != GPG_ERR_NO_ERROR )
{
// could not import public key file
GPGRELDATA pRelData = (GPGRELDATA) GetProcAddress(
hMod, "gpgme_data_release" );
if( pRelData != NULL )
pRelData( keydata );
GPGRELCTX pRelCTX = (GPGRELCTX) GetProcAddress( hMod,
"gpgme_release" );
if( pRelCTX != NULL )
pRelCTX( ctx );
freeResult = FreeLibrary( hMod );
// free the DLL module
return false;
}
}
If I test the following I get the ErrorCode GPG_ERR_INV_ENGINE
GPGENGINECHK pEngineChk = (GPGENGINECHK) GetProcAddress( hMod,
"gpgme_engine_check_version" );
if( pEngineChk != NULL )
{
if( pEngineChk( GPGME_PROTOCOL_OpenPGP ) == GPG_ERR_NO_ERROR )
...
The version no. of the engine cannot found but the file_name can.
Do you have any ideas how I can fix this error (compile gnupg-1.4.10 with valid
crypto engine)?
If you need more details please let me know!
A soon answer would be appreciated!
Thank you very much and
best regards
