Dsymname in GCC

[felix]

Hi,

I saw a code that pass to gcc at compilation time a option called Dsymname, so i looked at my gcc man pages and it doesn't say nothing about it. Someone know what it does ?

Regarsd,

You mean like "gcc -Dsymname"? If so, all that does is define a
macro by that name... Ie: exactly the same thing as just doing
"#define symname" within your code... If it was "-Dsymname=val",
then it's like doing "#define symname val"...

As for the point of the actual macro being defined, I have no idea...
Grep through the code, and see what depends on that macro's
value/definition or lack thereof...

Hello RobSeace,

Helped a lot. I understood for what use it. Only more one ask. If i make it in a module for kernel this symbol is automatically exported to other kenel functions and other modules ?

Um, no... Like I said, it only defines a macro... It's not a real
"symbol" in any way... It's a text macro, the same as you get
by doing #define... So, the only things that would be able to use
it are those that are compiled with that macro defined...
