[aspectc-user] __declspec issues

[John Hawkins]

Oh Dear - I think I might have got another MS specific issue.

Its now complaining about

c:/progra~1/micros~2/vc98/include/rpcdce.h:169: error: invalid declaration
near
token `RPC_IF_CALLBACK_FN'

Which appears to be a MS'ism ->
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/rpc/rpc/rpc_if_callback_fn.asp

Any clues as to how to get around this one (without using the purchased
system?

thanks for your help,
John

Hi John,


Most of the MS-specific language extensions are only parsed correctly
with the commercion version of ac++.exe, which is developed and sold by
pure-systems GmbH (http://www.pure-systems.com/) as part of their
VisualStudio AddIn.

As a workaround you may use "#ifdef __puma" which is defined during
parsing and weaving:

#ifdef __puma
    #define STORAGE_CLASS_INFO
#else
    #define STORAGE_CLASS_INFO __declspec(dllexport)
#endif

or, as a more general solution

#ifdef __puma
    #define __declspec(some_argument)
#endif


Have fun!

Daniel
