[Xenomai] Xenomai on Intel Edison

[Mäx Tanner]

Hello,

I have some troubles installing Xenomai 3.0.1 on the Intel Edison (Yocto
Linux). I really hope you can help me with the following error:

After extracting Xenomai, running ./bootstrap and ./configure without
errors - I get the following error trying to run ./prepare-kernel.sh: line
307: linux_: command not found
Line 307 consists of:
eval linux_`grep '^EXTRAVERSION =' $linux_tree/Makefile | sed -e 's, ,,g'`
The problem is that grep does not find EXTRAVERSION in the Makefile. Hence
it returns nothing and of course the OS can not recognize the command
"linux_". I checked the Makefile and there is no "EXTRAVERSION"
declaration, neither (following in the next lines of the
"prepare_kernel.sh") a "PATCHLEVEL", "SUBLEVEL" or "VERSION" declaration.
As result of that I think that my Makefile is not generated correctly. But
I don't see the point why?

Thank you very much!

Normally, the Linux kernel sources makefile contains something like:
VERSION = 4
PATCHLEVEL = 5
SUBLEVEL = 0
EXTRAVERSION =

Are you sure you pass the path to some kernel sources to
prepare-kernel.sh --linux parameter ?
