Searching DuckDuckGo for "undefined symbols ___plfortrandemolib_MOD_arange_1" I found this result:


https://stackoverflow.com/questions/53960548/compiling-plplot-with-gfortran


It says:

Based on this information, I changed your compile command to:


gfortran-mp-10 -ffpe-trap=invalid,zero,overflow -fcheck=all -finit-real=nan -g -lplfortrandemolib $(pkg-config --cflags --libs plplot-fortran) x00f.f90 -o x00f


This compiled successfully and runs:


./x00f
