Error installing package ClassInt

General
#1

Hi, trying to install ClassInt using RStudio and I see the following error:

"* installing *source* package ‘classInt’ ...
** package ‘classInt’ successfully unpacked and MD5 sums checked
** using staged installation
** libs
gfortran -fno-optimize-sibling-calls  -fPIC  -O2  -pipe -Wformat -Wp,-D_FORTIFY_SOURCE=2 -fstack-protector --param=ssp-buffer-size=4  -c fish1.f -o fish1.o
f951: Warning: command-line option ‘-Wformat=1’ is valid for C/C++/ObjC/ObjC++ but not for Fortran

Is that a bug in the package or a problem elsewhere?

Thanks
Dave

Hmmm, I'm out of ideas.
If I were in your shoes I would raise an issue at https://github.com/r-spatial/classInt/issues
