libgpgme-11.dll
For long and boring reasons I need to be able to call GPGME from Microsoft Visual C++. The MSVC linker requires .lib files, which are not shipped with GnuPG. That's okay: the procedure to make them is pretty straightforward. For each of libgpgme-11.dll, libgpg-error-0.dll, and libassuan-0.dll, I: 1. ran dumpbin /exports on it, to recover the function names 2. put these function names in a text file with "EXPORTS" at the top 3. ran lib /def:somefile.def /out:somefile.lib to create the .libs (Insert appropriate filenames for "somefile", of course.) A really basic test of GPGME passes: I can link against gpgme_check_version and confirm the correct version of GPGME. However, I can't actually *do* anything with it: gpgme_engine_check_version continually throws an invalid engine error, and gpgme_get_dirinfo keeps on returning nulls. So, if I had to wager a guess, GPGME isn't able to find GnuPG. My sample code runs just fine on OS X and Linux, incidentally, so I doubt the problem is with it. (If people want to see it just to make sure, I'm happy to provide it.) Anyone have any ideas? ___ Gnupg-users mailing list Gnupg-users@gnupg.org http://lists.gnupg.org/mailman/listinfo/gnupg-users

Signature check with libgpgme-11.dll
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-
Calling libgpgme-11.dll from Visual basic 6
I have been able to find the Win32 version of the gpgme library called libgpgme-11.dll from the gpg4win package. I am trying to figure out how to call it from visual basic 6. I have first started by looking how to call C dlls from vb: http://support.microsoft.com/kb/106553 I want to call the gpgme_new function which takes one parameter which is a context. It is declared in the .h file (used when calling from c++) as: /* The context holds some global state and configration options, as well as the results of a crypto operation. */ struct gpgme_context; typedef struct gpgme_context *gpgme_ctx_t; /* Create a new context and return it in CTX. */ gpgme_error_t gpgme_new (gpgme_ctx_t *ctx); To start, I just tried to set it up and call it like: Declare Function gpgme_new Lib "libgpgme-11.dll" (ctx) Sub Main() Dim ctx Dim gpgme_error gpgme_error = gpgme_new(ctx) End Sub It is able to find the dll and the reference to gpgme_new. If I put in the name of a function which doesn't exist, it complains. But it comes back with the error: Run-time error '49': Bad DLL calling convention I looked up this error and found: http://support.microsoft.com/kb/85108 This said something about calling ByVal which I tried and that didn't do anything. Seems to me, I need to figure out just what kind of object the ctx is and specify that specific type in the declaration. The way it is declared, it just looks like a pointer, but VB doesn't have a pointer type. I'm a beginner to this whole gpg and calling DLL thing. So I'm not even sure that it is possible to do this or if I'm just making a silly mistake in the declaration. If anyone can help out on how to call this dll, I would appreciate it. -thanks ___ Gnupg-users mailing list Gnupg-users@gnupg.org http://lists.gnupg.org/mailman/listinfo/gnupg-users
