Hello,
As far as I know, the linux kernel cannot be compiled as a C++ source;
I remember that I saw some explanations on why it cannot be treated as a
C++ code in more than one place. (I don'r rememer the exact reasons; maybe one
of the.
for example. was that there is a variable called new?)
However,I saw some places where you'll find #if defined(__cplusplus).
For example, in include/linux/stddef.h , you have
#if defined(__cplusplus) #define NULL 0 #else #define NULL ((void *)0) #endif
I wonder:
Why is this #ifdef exist at all if we know for sure that you can't compile the kernel as a C++ source code?
Regards, John
