[Xenomai-core] Latest snapshot (182) not compiling (kernel)

[Xenomai-core] Latest snapshot (182) not compiling (kernel)

[Ignacio García Pérez]

Hi,

I dunno what's changed, but I updated my xenomai snapshot to the latest
revision (182) and the kernel no longer compiles (fails due to some
xnpod_* undefined symbols).

Revision 179 compiled fine.

Nacho.

Hi,

I'm also having issues compiling the latest Xenomai tree.

I'm using revision 199 on a x86 Ubuntu 5.10 system with GCC 4.0.1 (is anyone
else using that one?).

Kernel config...?

Do you happen to have the IRQ shield switched on? May it's a regression
related to this per-default-off feature.

The problem appears to be gone when disabling the interrupt shield. (An
excerpt from my config can be found in my reply to Jan's e-mail.)

Confirmed here, there's indeed something fishy. Ok, I will look at this

ipipe-2.6.14-1.0-11 for x86 and ipipe-2.6.14-1.0-07 for ppc fix this.
Those patches are available from the Xenomai trunk, or from the Adeos dl 
area as usual.
