Hi.
I'm having problems building the user space for Xenomai 2.6.1 (for
AT91SAM9G20).
Long story short, I issue the following commands:
$ ./configure CFLAGS="-march=armv4t" LDFLAGS="-march=armv4t"
--host=arm-linux-gnueabi --enable-arm-tsc=at91
$ make DESTDIR=../xenomai_dest install
Here's a snippet of the error messages:
******************************************

If I don't choose TSC emulation for ARM, everything compiles fine.
Thank you.

According to this link:
http://www.atmel.com/devices/SAM9G20.aspx
The AT91SAM9G20 is based on an arm926 core, so, it is an armv5, not an
armv4.
And if you are compiling xenomai for a recent version of the I-pipe
patch, you do not need to pass the --enable-arm-tsc option. This option
is made for compiling xenomai for an old kernel.
Anyway, you can try the following patch:

...and if you are using a recent I-pipe patch, it is what you should do
anyway.
