Hi,
I am trying to use Intel ifort on Linux to compile source code that
uses the extension .F95. By default, ifort will not compile files
with this extension. To allow the compilation, the name of the source
file must be preceded by -Tf (treat the next option as fortran
source). While I know how to modify the Fortran flags, I don't know
how to add the '-Tf' flag that is directly in front of the source file
name (and after the -c). Can anyone point me in the right direction?
You could try this:
Edit
/Modules/Platform/Linux-Intel-Fortran.cmake
And add this:
SET(CMAKE_Fortran_COMPILE_OBJECT
"<CMAKE_Fortran_COMPILER> -o <OBJECT> <DEFINES> <FLAGS> -c -Tf
<SOURCE>")
FYI, I've investigated fixing this upstream. CMake should make sure
the compiler knows to compile as Fortran for any extension CMake
recognizes. For the Intel compiler, this means adding -Tf always.
Unfortunately it looks like -Tf implies -fixed too so it does not
work with free-format sources unless -free is also added. We cannot
add -free automatically because some sources might be fixed. The
solution ties into another item on my todo-list: we need a source
file property to mark every source as fixed or free format. It can
default based on file extension. The property would be used both
for adding "-fixed"/"-free" flags and to aid the dependency scanner
in identifying comments.
Summary: until the above is done we cannot add -Tf upstream :(
