Hi Alex,

Thanks for the very complete description of the problem.

The problem is indeed with GSL. The Steffen interpolation function in GSL (`gsl_interp_steffen') was added after version 2.0.

But during Gnuastro's configuration, it checks availability of this function on your system. If it is not found on your system, Gnuastro will not use it.

So, my guess is that since Gnuastro has passed the configure step, it has found this function in GSL. However, during the building of Gnuastro, because of some special environment variables it is linking with another (an older) GSL installation.

So probably you have two installations of GSL. You can check with this command (ignore the ones that are "Permission denied"):

$ find / -name "libgsl.*"

How did you install GSL 2.4 and 2.5? From source?

Another useful point is your Ubuntu version? According to Repology (link below), the GSL in any Ubuntu before 17.10 is before version 2.0.


So if you do these tests, we should be able to localize the problem and fix it ;-).

By the way, many new features have been added to Gnuastro and we will be releasing 0.9 soon. So you might want to try the most recent version (see the NEWS file for the many new features, and bugs fixed):
