[mesa-users] error during install

[<mar...@in...>]

Installing mesa code on windows xp with install script , with lastest version 
of MinGW, I have this
error, :

"RELERR: 1.00e-012 is below machine epsilon 0.00000e+000" (see attachment for 
screenshot error)

How to solve this problem ?
Many thanks.

Hi Marco,

It looks there is a numerical precision problem with the ndiff utility that
is used to check the output of MESA test codes to the expected results.  If
you look at the file

mesa/utils/test/ck12

it has the line

../../utils/ndiff/bin/ndiff -quiet -relerr 1.0e-12 tmp.txt test_output

You edit this fiel to use a larger value or relerr, or try compiling your
own version of ndiff on the Windows machine to see if that helps.  Let us
know if it does not.

Also, to send messsages to mesa-users, we ask that you subscribe to the
mesa-users list.  You can do that here:
