packed qualifier in c++ struct

[wink]

Hello everybody,

Developing embedded C++ applications I need to control the structure alignment with a the "packed" qualifier like this:

Code: [Select]

packed  struct MyStruct
{
   float AFloat;
   int AnInteger;
};

When I try to reverse this code, I get a parsing error.
I tried to declare a preprocessor macro "packed" but it doesn't help either.
This is funny beause if I put a stock macro like "PASCAL" instead of "packed" the parser accepts it.

This works:

Code: [Select]

PASCAL struct MyStruct
{
   float AFloat;
   int AnInteger;
};

I'd greatly appreciate any help!
Many thanks in advance,

cheers,
Manfred

Since 'packed' is not a standard C (or C++) keyword, I can see why you would get a parsing error, just as if you put in 'platypus'.

I can't see why it got rejected if you had killed it as an EA macro.
It should have been invisible.

See here: http://www.sparxsystems.com.au/cgi-bin/yabb/YaBB.pl?board=general;action=display;num=1103110378

It's possible that PASCAL is already eliminated by a similar macro definition somewhere - that works !

Hi Mike,

I totally agree with you, but unfortunately it doesn't work!  

It is like if only the stock macros would be recognized by the parser.

Hi guys,

I can confirm two things.

PASCAL is a macro with built-in support.

Adding packed as a macro should work, but instead reveals a bug that should be fixed for the next build.

Hi Simon,

thanks for the information!
Great to hear that this issue will be addressed in the next build.

keep up the good work,
cheers Manfred
