Dear Anthony and others,

I wanted to run the acutal CAMB Version from the net and get an error:

What compiler version?

[Martina Schwind]

The compiler version is:

schwind@pi213a:~/master-project/camb2$ ifort -v
Version 12.0.2

[Martina Schwind]

I changed the subroutine free_limber in modules.f90 but it doesn't change.

[Martina Schwind]

Now I downloaded the Version of March 2013 and this works.
I will continue now with this and check, whether the Version with Quintessence is working with this version as well...

[Antony Lewis]

As far as I can tell this is a compiler bug: works fine in ifort 13, but not in 12.0.2 (not exactly sure when they fixed it, but there were a lot of problems with some 12.x versions). Also works without openmp.

[Martina Schwind]

Thanks a lot, I will ask next week, when we will go on Version 13.
