Fail to generate .exe when compiling SWAT+ in linux

[Ann Wang]

Hi SWAT+ community,

I'm trying to use gfortran to compile SWAT+ in Linux. All the .f90 sources files have been successfully compiled into ".f90.o" files. But the compile process runs into error in merging all *.f90.o files into a single executable file, which is line 9696 in the "CMakeFiles/swatplus-unknown-gcc-lin_x86_64.dir/build.make".  The error message "cannot find -lm & -lc" as shown in the attached picture, seems to indicate that some of the libraries are missing for my environment.

Can anyone help to identify the specific libraries indicated by this error message? 

Many thanks,

Ann
