The developers for Valgrind (the debugging tool) had this to say about ARM support:
"As of early 2010, there is initial support for ARM/Linux. This is usable on Ubuntu 9.04 and Ubuntu 9.10 running on ARMv7 capable hardware (Cortex-A8). The repository currently contains support for the ARMv5 instruction set, some v6 instructions, and VFPv1. Work is in progress to expand this to cover the entire ARMv7 instruction set, including NEON and Thumb2 support, and to support Ubuntu 10.04."
So... that says they support the ARMv5 instruction set, but it doesn't say they support the processors. "Trunk" declines to compile on my plug, saying it doesn't support ARMV5TEL.
Does anybody know if you can build Valgrind for the plug?
