The command: make ARCH=arm CROSS_COMPILE=arm-unknown-linux-gnu- uImage
is the command I use to cross compile kernels for my AT91 board, and I have successfully cross-compiled several kernels, so I think AS is the cross-as not the system-as. It seems like my cross-as doesn't support that assembler instruction.. (arm-unknown-linux-gnu-as version is: GNU assembler 2.16.1) ----- Messaggio originale ----- Da: "Gilles Chanteperdrix" <[email protected]> A: "Forconi" <[email protected]> Cc: [email protected] Inviato: Giovedì, 27 settembre 2012 14:06:26 Oggetto: Re: [Xenomai] Xenomai 2.6.1 - Linux 2.6.38.8 on AT91SAM9260 - Kernel compilation fails On 09/27/2012 12:05 PM, Forconi wrote: > Hi, this is my first approach to Xenomai, I'm trying to compile a > Xenomai patched Linux kernel to run on a AT91SAM9260 embedded board. > > This is my environment: CROSS-GCC: gcc-4.2.3-glibc-2.3.3 KERNEL: > Linux 2.6.38.8 XENOMAI: Xenomai-2.6.1 > > I'm following the "Installation instructions" on web site (section > 3.4.

No, the problem is the toolchain. Are you sure AS is $(CROSS_COMPILE)as and not the build system as ? -- Gilles. -- Ing. Samuele Forconi Responsabile Sviluppo SW WaveComm S.r.l.
