If possible, please build and run the sample here and reply with the
output, etc.:

Thanks.

spu-gcc -Wall hello_spe.c -o hello_spe.elf

Apparently I had a few attempts at installing various version of libspe2. I might have copied some files across manually and forgot to clean up afterwards---I can't remember. Anyway, the sample compiles and runs:

$ ./hello_ppe.elf
Hello world!

This tallies with my experience from before: I can write code (like hello_spe.c above) that I know is running on the SPUs, but the problem is just with the spufs. Michael Ellerman's previous reply about the kernel patch looks like it should solve the problem, if only I knew how to compile the 3.10 kernel under my mix of firmware (3.55) and OtherOS++ (using reboot otheros/reboot package files to start linux from within the PS3 interface).

Anyway, thanks for the reply. I'm not sure if the results are any good for you, but maybe it helps?
Thanks,
