Compiling Fortran source files using a makefile - makefile

Question

I have several Fortran source files that need to be compiled and link together to form an exe computational code. There is also a makefile.dos in the package but I don't know how to use it to compile the Fortran files.
I tried to compile source files with Intel parallel studio without using the makefile, with
ifort /O3 /QxHost /Qparallel /Qdiag-disable:warn *.for
The APP.exe created successfully but it seems that the timer routine has not been compiled properly. Because when I execute the code, the timing of processes are not recorded in the output file. I guess compiling with the makefile may resolve the issue.
Then I tried to compile the Fortran Files with the help of the makefile by:
nmake /f makefile.dos FPP=ifort LINK32=386link
This time I got the following error:
NMAKE : fatal error U1073: don't know how to make 'app.OBJ'
What am I doing wrong? My OS is WINDOWS 10 LTSC.
Here is the content of the makefile (In the code package there are those items that are listed in front of "SRCS" variable below):
FC = f77l3
LINKER = 386link
PROGRAM = APP.exe
