Re: [Xenomai-help] Cross-link.c ---RTSER_RTIOC_WAIT_EVENT
ok for CC, i was afraid of spam everyone by my mail. I answer your questions. - non, i didn't modify cross-link program (even if i used to modify this program to make it run, but it worked the same way) - Xenomai 2.6 - Linux 2.6.38 and patch Adeos 2.6.38 of course - i build the program in Eclipse C++ so my command in setting configuration is command : g++ All options: -l/usr/xenomai/include -O3 -wall -c -fmessage-length=0 Well, i will soon rebuild my kernel with this patch Goodbye On Wed, Apr 11, 2012 at 9:01 PM, Wolfgang Grandegger w...@grandegger.comwrote: On 04/11/2012 06:59 PM, Gilles Chanteperdrix wrote: On 04/11/2012 06:56 PM, Gilles Chanteperdrix wrote: On 04/11/2012 04:19 PM, Wolfgang Grandegger wrote: Hi, On 04/05/2012 02:46 PM, Minh GIANG wrote: i'm sorry sir, what i displayed just in the last mail, isn't good, because i removed rt_dev_ioctl(...) in cross-link program And then, with rt_dev_ioctl( RTSER_RTIOC_WAIT_EVENT ).
