building stopped with something related with libarmadillo-dev ?

Hi, guys, thanks for the new code!
I have a try with the Fringe code today. My compiling and building stopped at the Fit function.
It seems a problem of libarmadillo-dev, which I installed with apt-get under ubuntu with anaconda3.
Please see the following screen report. Any suggestions? thanks!

What Ubuntu version are you on? I think arma::index_min requires Armadillo version 8.100. Could you check what version you have installed?

Thanks! That's great! I changed armadillo from v 6.5 to v 8.1. It works very well!
