Im confused I extract tar xf xenomai-3.0.5.tar.bz2 in my home folder /home/henoInstall/xenomai-3.0.5
but /usr/src/linux-headers-4.9.38-xenomai-3.0.5 I guess it is kernel source folders isn't it ? it consist /usr/src/linux-headers-4.9.38-xenomai-3.0.5/include/xenomai/rtdm and after apply patch and build kernel folder /usr/xenomai is appeared but therein't features.h file ----- Original Message ----- From: "Greg Gallagher" <g...@embeddedgreg.com> To: "Шевченко Тарас Григорьевич" <shevchenko.ta...@triolcorp.com.ua> Cc: "xenomai" <xenomai@xenomai.org> Sent: Friday, March 9, 2018 2:08:14 PM Subject: Re: [Xenomai] cant compile rtdm module Are the Xenomai headers loacted in your kernel source?
