[Cmake] Re: How to support FORTRAN ?

[Andy Cedilnik]

Hi Fang,

There is a plan for adding fortran support in CMake, but until that is
not done, you can always use custom commands to do it. This is all well
documented in Mastering CMake on pages 80 - 87.

It works something like this:

1. Compile fortan file foo.f and bar.f to foo.o and bar.o
2. Link foo.o and bar.o to libFooBar.a
3. Link libFooBar.a to your executable

So, #1:

ADD_CUSTOM_COMMAND(
  OUTPUT ${CURRENT_BINARY_DIR}/foo.o
  DEPENDS ${CURRENT_SOURCE_DIR}/foo.f
  COMMAND ${FORTRAN_COMPILE}
  ARGS -o ${CURRENT_BINARY_DIR}/foo.o ${CURRENT_SOURCE_DIR}/foo.f)

same for bar.f

#2:

ADD_CUSTOM_COMMAND(
  OUTPUT ${CURRENT_BINARY_DIR}/libFooBar.a
  DEPENDS ${CURRENT_BINARY_DIR}/foo.o ${CURRENT_BINARY_DIR}/bar.o
  COMMAND ${CMAKE_AR}
  ARGS cr ${CURRENT_BINARY_DIR}/libFooBar.a ${CURRENT_BINARY_DIR}/foo.o
${CURRENT_BINARY_DIR}/bar.o)

And then #3:

ADD_CUSTOM_TARGET(
  Fortranlibrary
  DEPENDS ${CURRENT_BINARY_DIR}/libFooBar.a)

Now, when you use FooBar, you do something like:

TARGET_LINK_LIBRARY(MyExec ${CURRENT_BINARY_DIR}/libFooBar.a)

Make sure MyExec and Fortranlibrary are in the same directory.
