"Disabled Math Support" Syntax Error #3

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Background:
* I use a Linksys WRT54GS v.6 router with DD-WRT v.24 SP2.
* I downloaded the most recent wrtbwmon yesterday (1/11/2010), saving it in 
/tmp/
* I set up the cron jobs, as suggested on the 'deploying' page.

*******************************

After 20 hours, I realized that I was not getting proper output.  I tried 
to run a few of the commands that cron runs myself, like:
% /tmp/wrtbwmon setup br0
and
% /tmp/wrtbwmon update /tmp/usage.db peak

But I got an error: 
/tmp/wrtbwmon: line 90: syntax error: you disabled math support for 
$((arith)) syntax

Any suggestions?  Do you have any ideas how to enable math support on DD-
WRT?

Thanks, and sorry for being a script n00b!

Alright.... it looks like sh in the micro version of linux does not support 
in-line 
math of the form $((Arithmetic)), like line 90: $((${BYTES}/1000)), and lines 
91, 
116, 117, 119, and 120.  Are there other ways to do in-line math?  Programs 
like bc 
and expr  are not loaded in dd-wrt, so we can't use those.

Any suggestions on how I can alter lines 90, 91, 116, 117, 119, and 120 to 
accommodate dd-wrt v.24 SP2?

Thank you!

There are issues with the micro version of dd-wrt.  The minimum supported 
version of
dd-wrt is micro-plus.
http://www.dd-wrt.com/wiki/index.php/Micro-plus
The WRT54GS v6 does not seem to support it though, confirmed by
http://www.dd-wrt.com/phpBB2/viewtopic.php?p=281390 :(
I will have a look on how to do arithmetics differently later, but there may be 
other
issues down the track. Busybox in the micro version is way too much stripped 
down.

Cool; thanks for getting back to me and being so thorough!  I'll look into the 
in-line 
math thing some more myself, and see what I can find.  Thanks!
