[Xenomai] Compilation errors for Linux kernel 3.10.18 + ipipe-core-3.10.18-arm-1.patch + xenomai-3-3.0-rc2.tar.bz2.

[satya patel]

Hi,

I am trying to apply “ipipe-core-3.10.18-arm-1.patch” to Linux kernel
3.10.18. (Arm Platform, with default config file - omap2plus_defconfig)

When I apply the patch using Xenomai 2.x (xenomai-2.6-2.6.0-rc5.tar)
compilation is successful after following the instructions mentioned in the
below link:

http://xenomai.org/installing-xenomai-2-x/

i.e. compilation for - Linux kernel 3.10.18  +
ipipe-core-3.10.18-arm-1.patch + xenomai-2.6-2.6.0-rc5.tar Is OK.



However, I get compilation errors for below combination.

Linux kernel 3.10.18  + ipipe-core-3.10.18-arm-1.patch +
xenomai-3-3.0-rc2.tar.bz2 --- COMPILATION ERRORS.

Please let me know how to compile for *Linux kernel 3.10.18  +
ipipe-core-3.10.18-arm-1.patch + **xenomai**-3-3.0-rc2.**tar.bz2*

Regards.

omap2plus_defconfig is a bad idea. If you want a kernel which
compiles fast, and with the least possible run-time overhead, you
should tailor your configuration to your hardware. Notably,
omap2plus_defconfig enables CONFIG_SMP, which you may not need if
you are not compiling for omap4 or omap5.

This is what you get by not using the latest patch. The latest
I-pipe patch for Linux 3.10, which you can find on Adeos download
area, is:
 
ipipe-core-3.10.32-arm-6.patch

Why on earth do you use xenomai 2.6.0-rc5, whereas the latest stable
version is xenomai 2.6.4?
