Hello everyone,

I am using some Linux Kernel code (list implementation) in my Visual Studio 2005 (C++),

It reminds me

'typeof': identifier not found'.

I tried __typeof__ but still not working.

Any idea ?


Thx,

Code snippet and/or source filename please?

It is the list implementation in Linux. (include/linux/list.h), It is already used by my code in Linux version and I prefer to change a little bit to adapted to Windows

The function has typeof type as one of its parameters:

------------------------------------------------------------------

#define list_for_each_entry_safe(pos, n, head, member) \
for (pos = list_entry((head)->next, typeof(*pos), member), \
n = list_entry(pos->member.next, typeof(*pos), member); \
&pos->member != (head); \
pos = n, n = list_entry(n->member.next, typeof(*n), member))



-------------------------------------------------------------------


Thx,

HI, Paul, I use typeid() instead of typeof and it works.

Cool - glad you found a solution.

For whatever it's worth, I'm familiar with both GCC and Visual Studio ... and I wasn't aware of the "typeof" <=> "typeid" solution> Thank you for the tip!

Also for whatever it's worth, the kernel authors make no bones about the fact that Linux really isn't meant to be built with any compiler besides gcc. *Platform* portability is an important consideration (Linux runs on lots of different kinds of hardware). *Compiler* portability isn't: gcc is available (or can be readily bootstrapped) wherever it's needed; ANSI C doesn't provide all the needed features (I guess "typeof" is one good example!). So GCC is pretty much the "annointed compiler" for Linux kernel code.

IMHO .. PSM

PS:
I would argue, however, that all good *application* code (vs. "kernel code") should be written in portable ANSI C or ANSI C++ whenever practical.
