hello guys


following the procedure from
hart.sourceforge.net/rtai_installation_10_04_woc.html

RTAI metapackage is not in synaptic ONLY the DOCS

here is the commandline in question following the instructions on HART

sudo apt-get install linux-headers-2.6.32-122-rtai linux-image-2.6.32-122-rtai

comes up with
****~/Downloads/rtai$ sudo apt-get install linux-headers-2.6.32-122-rtai linux-image-2.6.32-122-rtai
Reading package lists... Done

E: Couldn't find package linux-headers-2.6.32-122-rtai

so went to the RTAI website and downloaded latest RTAI tarball ver 3.8.1

using terminal and the ./configure after untarballing

I get this..... (last few lines of ./configure output)

checking for RTAI Kconfig file... ./base/arch/x86_64/defconfig (default)
checking for module installation directory... ${exec_prefix}/modules
checking for Linux source tree...
configure: error: No Linux kernel tree in /usr/src/linux

I did some research and found out on older versions they use a "kernel source package with patches"
so off to synaptic and there is the kernel source with patches. so i downloaded and tried terminal again

checking for RTAI Kconfig file... ./base/arch/x86_64/defconfig (default)
checking for module installation directory... ${exec_prefix}/modules
checking for Linux source tree...
configure: error: No Linux kernel tree in /usr/src/linux

so clearly that didnt work

apparently it needs the headers and images installed for the directory tree "according to some forum posts over the net"

leading me back to the 4th to14 lines of this post (back to the beginning)

could it be that the configure file is too narrow and looking for older images/headers/kernel sources i dont have installed?

if so what post ./configure commands should i use to change the kernel tree directory

and why doesnt RTAI show up in synaptic? it use to! i have it installed on another machine from there!!!

should i be contacting some one about this??? can any one else get RTAI?
