[aspectc-user] __declspec issues

[John Hawkins]

Hi again,

OK, I've got the gist of what's going wrong but losing the plot as to how
to fix it.
I've currently got the following options (on the command line) ->
-D_WIN32
-DWIN32
-D_WINDOWS
-D_MBCS
-D__cplusplus
-I%compilerincludedir%
-v9
--problem_local_class
-A machine(i386)
-A platform(win32)
--vc
-D_USRDLL

NOTE: "-A platform..." is spelt "-A plattform" in the sample conf file
(issue?)

I'm getting the following errors -

c:/progra~1/micros~2/vc98/include/winnt.h:630: error, Must define a target
architecture.
c:/progra~1/micros~2/vc98/include/stdio.h:77: error: `signed' or `unsigned'
invalid for given type
c:/progra~1/micros~2/vc98/include/winnt.h:22: error: invalid declaration
near token `"C"'
  - Aborting

Now, I can see these errors but can't work out why it needs me to define a
target architecture - When I compile my code using MSVC or ant (using MSVC)
I don't see any flags to indicate target architecture

This must be another one of my dumb errors - so can you point me in the
right direction please?

thankyou,
John.

John,

As the weaver is complaining about the line, I doubt that this is a VC6
specific issue.

RPC_ENTRY is defined as __stdcall, RPC_STATUS as long and IN/OUT are
just for documentation purposes and defined as nothing, so the line

typedef RPC_STATUS RPC_ENTRY
RPC_IF_CALLBACK_FN (
     IN RPC_IF_HANDLE  InterfaceUuid,
     IN void *Context
     ) ;

expands to

typedef long __stdcall
RPC_IF_CALLBACK_FN (
      RPC_IF_HANDLE  InterfaceUuid,
      void *Context
     ) ;


which should not result in any weaving problems.
I was not able to reproduce your problem, regardless of using the free
or commercial edition, VC6 headers or newer ones from the PlatformSDK.
I tried the following test application and did not encounter any problems:

// main.cpp
#include <stdio.h>
#include <windows.h>
#include <rpcdce.h>
int main() {

    printf( "Hello from main!\n" );
    return 0;
}

// aspect.ah
#include <stdio.h>
aspect Hello {
    advice execution( "% main(...)" ) : before() {
        printf( "Hello from Aspect :-)\n" );
    }
};

This all makes me believe that the real problem is somewhere else and
for some reason not detected/reported earlier during the weaving process.
Maybe you can track down the thing to a smaller test app so we can
reproduce it?

Regards

Daniel
