Ethan, Jeff,

Sorry for the perl confusion, nevermind...

Below is attached the log and ini files, and also how I run MTT.

Thanks,

Rafael

[Jeff Squyres (jsquyres)]

Btw, I agree w ethan: the syntax looks good to me. @ tells how to cast the 
reference; it doesn't dereference to get the first element. 

But we need to see your ini file to be sure (I don't have the mtt code here w 
me to check it for sure).

How do perl -V differ between the two distros?

I can not reproduce the error on a SLES 10 machine.

Could you run MTT with the --debug option and send the output with the
line 75 perl error? That might help me determine which INI param is
responsible for the error.

Could you run MTT with the --debug option and send the output with the
line 75 perl error? That might help me determine which INI param is
responsible for the error.

Re: [MTT users] MTT Error on SLES11

[Rafael Folco]

Well, I took a look at /tmp/ompi-core-testers/lib/MTT/Values.pm line 75.

This piece of code looks wrong to me:

 if ($#{@$ret} < 0) {

$ret references an array
@$ret points to the first element of this array
$# returns the number of elements

So this line is trying to count elements of the first element??! Doesn't
make sense. Correct me if I am wrong, what am I missing here ?

"if ($#{$ret} < 0) {" would be correct, without @. 

I believe "strict refs" has been forced somewhere on SLES11... I also
tried on other distro and it works fine.

Thanks,

Rafael
