iwlib.h (or any other userspace app) must not include <linux/*> and 
<asm/*> files. If it needs access to them for accessing ioctl API
(or anything else), maintainer must create stripped-down copy of
these headers, and distribute them with app - which is btw only
correct way, as otherwise you cannot create userspace app which
will support more than one API version (and iw used couple
of incompatible APIs in the past...).

Thank for reply

Problem found and corrected...Suppose to get rid of old eyeglases..Buy
new with gain 7..-)
Or cosider to syop by some reading cource....

I was too heated to get new stuff on production and read too hastly
documents.
In makefile was possibility to choose right version of glibc...When found
that..voila'.
Thanks for partisipating....

My previous question about iwlib

[jarmo kettunen]

I'm sorry,if my previous message was incorrect about iwlib maintaining...
Suppose this example lights more than my words what I want to ask.

As I have no knowledge of code,asked wireless-tools maintainer what's wrong 
got answer,what I wrote in my previous message.....

So coul someone enlight me what to do....
