[okl4-developer] Error building OKL 1.5.2 for imx31 on Fedora7 & python2.5

[Nelson Tam]

Hi Mike,

I've just tried doing the same build on the 2.1 release just then, it  
worked fine for me.

The variable expect_test_data is actually just a string that is used  
in our testing system, it is compared against stdout during testing.

The reason for the first failure is because on the line that you've  
commented out, characters are prepended onto expect_test_data but the  
variable is not defined yet.  Commenting out this line merely delays  
the problem till later.

A better solution would be to set the string to "" if it is not  
defined already, or specify "example=dining_philosophers" (or anything  
in iguana/examples), which will initialise expect_test_data for you.

Nelson.
