Hi Fortran experts here,
I am following source code from <>.
it has one module called toolbox with hundreds of subroutines.
I am using a cygwin system to run this code.
I am trying to run a program called prog02_02.f90
A: it uses toolbox.f90 module
B: I run gfortran -c toolbox.f90 prog02_02.f90
C: it generates: toolbox.mod, toolbox.o, prog02_02.o
D: I run: gfortran toolbox.o prog02_02.o
it give error message: undefined reference to `omp_get_wtime_’ error
see the screenshot attached.
if this error is something very common, I will appreciate if any expert can simply point out some solution to solve it.
I appreciate your time and help.
