[Xenomai-core] xeno-load: line 182: 2794 Floating point exception$suflag $* $cmdargs

[Jim Cromie <jim.cromie@domain.hid>]

I get the above error when running xeno-test,
or when running individually, like so:

soekris:/usr/xenomai/bin# ( cd ../testsuite/switchbench; loudly ./run -- 
-p 10
-n -l 1000 $XENOT_SWITCHBENCH '# switchbench';     )

Sun Aug 20 18:51:53 MDT 2006
running: ./run -- -p 10 -n -l 1000 # switchbench
*
*
* Type ^C to stop this application.

== Sampling period: 10 us
== Do not interrupt this program
/usr/xenomai/bin/xeno-load: line 182:  2868 Floating point 
exception$suflag $* $cmdargs



but I dont get it when running it manually, w/o the ./run wrapper.

soekris:/usr/xenomai/testsuite/switchbench# switchbench

BTW, the line-number given above is a red-herring:

    177 while test -n "$target_info" ; do
    178   action=`echo $target_info|cut -d';' -f1`
    179   target_info=`echo $target_info|cut -s -d';' -f2-`
    180   set -- $action
    181
    182   case "$1" in
    183
    184     push)


I stuffed in an strace, and got this:

+ test ./switchbench = ./switchbench
+ waitflag=1
+ set -- ./switchbench
+ test 0 = 1
+ test 1 = 1
+ echo what ./switchbench -p 10 -n -l 1000

BTW

over the past year, Xenomai has moved away from (at least some) of the 
ideosyncracies
it used to have:

- modules now get installed with rest of kernel, so modprobe etc just work
    this suggests that some parts of xeno-load are now obsolete / 
unnecessary.

- ive set LD_LIBRARY_PATH to make life more convenient

Im (idly) wondering if theres more to do, what things need to be done 
1st, etc..


FWIW  switchtest output is pretty ;-)
