Hi Jon -
More info about crunch compiling, linking, library requirements and
performance is at:
http://arm.cirrus.com/files/linux/crunch/
(Also in a tar archive, same directory).
Basically you have to statically link any executable that uses crunch,
unless you use EABI. But EABI is a big step, needing a complete new
(2.6) kernel and runtime environment. Can be daunting if you are not
familiar with linux development. See
http://wiki.debian.org/ArmEabiPort
for more info about EABI, especially the section on floating point.
More (pre-EABI) FP background info, and why it is so slow on ARM w/o
softfloat, is at:
http://www.arm.linux.org.uk/mailinglists/faq.php#f3
I'd be happy to benchmark any of your code for you under EABI, if you
want any comparison data.
Regards, ......... Charlie
