Hi,
While trying to compile rtnet 0.6.0 on my debian testing box (gcc 3.3.3, kernel 2.4.24-adeos, rtai-3.0), I get the same error as Hans-Peter Bock described in <http://sourceforge.net/mailarchive/message.php?msg_id=7010119>
Nor the patch of Jan <http://sourceforge.net/mailarchive/message.php?msg_id=7010108> nor the one of Takis <http://sourceforge.net/mailarchive/message.php?msg_id=7010126>
change anything for me
I also tried latest CVS, but that didn't help either.
As CVS is still broken - they are promising to fix it until tomorrow - here comes a patch which should finally solve your issue.
The problem was my misunderstanding of the usage of the _IOW/_IOR macros: the size parameter has to be specified without any "sizeof". Your debian testing comes with new 2.6 user headers which now do some new verifications of this parameter, and these tests failed.
