| = Introduction =
| | This page has moved [https://gitlab.kitware.com/cmake/community/wikis/doc/cmake/languages/fortran/Fortran-Issues here]. |
| CMake has a number of Fortran issues that have been discussed many different times on list and duplicated a fair number of times in the bug tracker as well.
| |
| | |
| Maik Beckmann is trying to make sense of all the confusion by collecting information on all Fortran issues at http://www.cmake.org/Bug/view.php?id=5809
| |
| | |
| Please join the work there by
| |
| | |
| * Contributing patches.
| |
| * Testing the patches that already exist there.
| |
| * Reporting things that don't work.
| |
| * Sending simplified examples of things which don't work.
| |
| * Sharing your expert knowledge of CMake.
| |
| | |
| = Concepts expressed using Makefiles =
| |
| | |
| This section is intended to discuss the makefile rules which CMake has to | |
| generate.
| |
| | |
| == A simple program ==
| |
| | |
| A f9x program which is build by compiling in linking two source files ''a.f90'' and ''main.f90''.
| |
| The tree structure is:
| |
| * example_simpleProgram
| |
| ** build
| |
| *** Makefile
| |
| *** prog.dir
| |
| **** build.make
| |
| ** main.f90
| |
| ** a.f90
| |
| | |
| a.f90:
| |
| <pre>
| |
| SUBROUTINE printHello
| |
| WRITE(*,*) "Hello f9x world"
| |
| END SUBROUTINE
| |
| </pre>
| |
| | |
| main.f90:
| |
| <pre>
| |
| PROGRAM hello
| |
| CALL printHello
| |
| END PROGRAM
| |
| </pre>
| |
| | |
| Makefile:
| |
| <pre>
| |
| all: prog.dir/all
| |
| | |
| prog.dir/all:
| |
| $(MAKE) -f prog.dir/build.make prog.dir/all
| |
| | |
| clean:
| |
| $(MAKE) -f prog.dir/build.make prog.dir/clean
| |
| </pre>
| |
| | |
| build.make:
| |
| <pre>
| |
| prog.dir/all: prog.dir/prog
| |
| | |
| prog.dir/prog: prog.dir/a.o prog.dir/main.o
| |
| gfortran -o prog.dir/prog prog.dir/a.o prog.dir/main.o
| |
|
| |
| prog.dir/a.o: ../a.f90
| |
| gfortran -o prog.dir/a.o -c ../a.f90
| |
|
| |
| prog.dir/main.o: ../main.f90
| |
| gfortran -o prog.dir/main.o -c ../main.f90
| |
|
| |
| prog.dir/clean:
| |
| rm prog.dir/a.o prog.dir/main.o prog.dir/prog
| |
| </pre>
| |
| | |
| Now change into ''build'' and type
| |
| : $ make
| |
| to build. The current CMake is able to build the same without any problems. This is also valid for any fortran code that doesn't use modules.
| |
| | |
| You can download this example as tarball example_simpleProgram.tar.gz at http://www.cmake.org/Bug/view.php?id=5809
| |
| | |
| == A simple program with module ==
| |
| | |
| The same as before, but now ''a.f90'' provides a module which ''main.f90'' uses.
| |
| The tree structure is:
| |
| * example_simpleProgram_withModule
| |
| ** build
| |
| *** Makefile
| |
| *** prog.dir
| |
| **** build.make
| |
| ** main.f90
| |
| ** a.f90
| |
| | |
| a.f90:
| |
| <pre>
| |
| MODULE localMod
| |
| !
| |
| CONTAINS
| |
| SUBROUTINE printHello
| |
| WRITE(*,*) "Hello f9x world"
| |
| END SUBROUTINE
| |
| END MODULE
| |
| </pre>
| |
| | |
| main.f90:
| |
| <pre>
| |
| PROGRAM hello
| |
| USE localMod
| |
| CALL printHello
| |
| END PROGRAM
| |
| </pre>
| |
| | |
| Makefile:
| |
| <pre>
| |
| all: prog.dir/all
| |
| | |
| prog.dir/all:
| |
| $(MAKE) -f prog.dir/build.make prog.dir/all
| |
| | |
| clean:
| |
| $(MAKE) -f prog.dir/build.make prog.dir/clean
| |
| </pre>
| |
| | |
| build.make:
| |
| <pre>
| |
| prog.dir/all: prog.dir/prog
| |
| | |
| | |
| prog.dir/prog: prog.dir/a.o prog.dir/main.o
| |
| gfortran -o prog.dir/prog prog.dir/a.o prog.dir/main.o
| |
| | |
| prog.dir/a.o: ../a.f90
| |
| gfortran -o prog.dir/a.o -c ../a.f90 -M prog.dir
| |
|
| |
| prog.dir/localmod.mod: prog.dir/a.o
| |
|
| |
| prog.dir/main.o: ../main.f90 prog.dir/localmod.mod
| |
| gfortran -o prog.dir/main.o -c ../main.f90 -I prog.dir
| |
|
| |
| prog.dir/clean:
| |
| rm prog.dir/localmod.mod prog.dir/a.o prog.dir/main.o prog.dir/prog
| |
| </pre>
| |
| | |
| Now change into ''build'' and type
| |
| : $ make
| |
| to build. This is nothing the current CMake can't do. Now
| |
| do (you're at the build directory)
| |
| $ touch ../a.f90
| |
| and enter
| |
| $ make
| |
| again. You'll see that a.f90 is recompiled, like the current CMake does,
| |
| but main.f90 is recompiled too! This is different from current CMake, but its
| |
| the right way, since a module dependency is a compile time dependency like an
| |
| include.
| |
| | |
| == Executable depending on external lib ==
| |
| | |
| This example build a executable target which
| |
| # provides a module
| |
| # uses the provided module
| |
| # uses a module of a external library
| |
| | |
