Create a makefile

[felipin85]

Hi everybody!

I would like create a makefile to solve a big problems (using Lapack 95 and mkl_dss). The main programwill haveseveraldependent files(subroutines).

For example the main program is hola.f90, the subroutine dependent is escribir.f90. I write a makefile, but I get the following message:

felipe@felipe-desktop:~/Escritorio/mis pruebas make$ make

make: *** No hay ninguna regla para construir el objetivo ESCRIBIR.o, necesario para hola. Alto.

If, I translate to English for you:

make: *** Don't exist any rule to build the objetive <>, necesary for <>. Stop

Please, I would like create the makefile, that If I change something in Escribir.f90 or hola.f90, these are update.That is,the filesarecompiledand linking.

If they can nothelp meorgoes outsidethescope oftheforum,Iwould like toknowwhereto finddocumentation.

Thanks for your help,

Felipe

Make is telling you that it does not have a built-in rule to make .o files from .f90 files.

Your makefile already has lines for a ".f90 .o" rule, but those lines are prefixed by '#' in column-1. Simply removing the #s will take you to the next step.

I'm changed the makefile, but I have the same problem:

felipe@felipe-desktop:~/Escritorio/mis pruebas make$ make

make: *** No hay ninguna regla para construir el objetivo hola.o, necesario para hola. Alto.

felipe@felipe-desktop:~/Escritorio/mis pruebas make$ make hola

make: *** No hay ninguna regla para construir el objetivo hola.o, necesario para hola. Alto.

I created a new makefile, this works better than the other, but I have any problem, for example:

felipe@felipe-desktop:~/Escritorio/mis pruebas make$ make

make: *** No hay ninguna regla para construir el objetivo hola.o, necesario para hola. Alto.

felipe@felipe-desktop:~/Escritorio/mis pruebas make$ make hola

make: *** No hay ninguna regla para construir el objetivo hola.o, necesario para hola. Alto.

felipe@felipe-desktop:~/Escritorio/mis pruebas make$ make

make: *** No hay ninguna regla para construir el objetivo hola.o, necesario para hola. Alto.

felipe@felipe-desktop:~/Escritorio/mis pruebas make$ make todo

make: *** No hay ninguna regla para construir el objetivo hola.o, necesario para hola. Alto.

felipe@felipe-desktop:~/Escritorio/mis pruebas make$ make hola

make: *** No hay ninguna regla para construir el objetivo hola.o, necesario para hola. Alto.

felipe@felipe-desktop:~/Escritorio/mis pruebas make$ make compilar

ifort -openmp -O3 -c hola.f90 escribir.f90 -I/opt/intel/composerxe-2011/include/ia32 -L/opt/intel/composerxe-2011.0.084/mkl/lib/ia32 -lmkl_lapack95 -Wl,--start-group /opt/intel/composerxe-2011.0.084/mkl/lib/ia32/libmkl_intel.a /opt/intel/composerxe-2011.0.084/mkl/lib/ia32/libmkl_intel_thread.a /opt/intel/composerxe-2011.0.084/mkl/lib/ia32/libmkl_core.a -Wl,--end-group -liomp5 -lpthread

ifort: error #10104: unable to open '--end-group'

make: *** [compilar] Error 1

felipe@felipe-desktop:~/Escritorio/mis pruebas make$ make hola

ifort -openmp -O3 -o hola hola.o escribir.o -I/opt/intel/composerxe-2011/include/ia32 -L/opt/intel/composerxe-2011.0.084/mkl/lib/ia32 -lmkl_lapack95 -Wl,--start-group /opt/intel/composerxe-2011.0.084/mkl/lib/ia32/libmkl_intel.a /opt/intel/composerxe-2011.0.084/mkl/lib/ia32/libmkl_intel_thread.a /opt/intel/composerxe-2011.0.084/mkl/lib/ia32/libmkl_core.a -Wl,--end-group -liomp5 -lpthread

But, althoughthere areerrors,thefinalwork.Iwish I coulddoalonemake,andeverythingis built.I guessit'sasimple commandthat I have not.

Theedited file works is Makefile, and the first file changed (clean the coments #) is Makefile1.

Thanks for your help,

Felipe

I do not know what you have in the modified makefile, so here is a simplified makefile that produces the correct commands.

[bash]FC= ifort
.SUFFIXES: .f90 .o

OBJS= hola.o escribir.o
FFLAGS= -openmp -O3
MKLINCLUDE=/opt/intel/composerxe-2011/include/ia32
MKLPATH=/opt/intel/composerxe-2011.0.084/mkl/lib/ia32/
hola: $(OBJS)
	$(FC) $(FFLAGS) -o  hola $(OBJS) -L$(MKLPATH) -lmkl_lapack95 -Wl,--start-group $(MKLPATH)/libmkl_intel.a $(MKLPATH)/libmkl_intel_thread.a $(MKLPATH)/libmkl_core.a -Wl,--end-group -liomp5 -lpthread
.f90.o:
	$(FC) $(FFLAGS) -c $< -I$(MKLINCLUDE)
clean:
	rm hola $(OBJS)
[/bash]

Note that I have removed linker options from the .f90.o rule.
