Re: [CMake] Actual effect of set_source_files_properties with COMPILE_FLAGS - solved
Hello everybody,
that's finally OK. Indeed; everything was OK. I did not pay attention
that the flag was actually here. I was simply not looking
in the right place. Perhaps new glasses or some rest should be my first
resolution for 2012 !!!
sorry for the inconvenience

Hello everybody,
I work on a Fortran library that for historical reasons should be
maintained with intel fortran compiler, g95 and gfortran
on Linux, Windows and MacOS platoform. Everything everywhere :o !
My library is made of 50 files. Among those files, most of them will
have to be compiled with a set of flags that
does not match the CMake default ones. But, for a few of them (4
actually) there are some slight variations. For instance,
with g95, 46 files has to compiled with -std=f2003 while the 4 others
ones should have this flag unset.
The strategy I decided to adopt is the following:
- use of a macro to set the standard flags (see attached file
set_compiler_flags.cmake)
- use of set_source_files_properties(${SOURCES} PROPERTIES
COMPILE_FLAGS -std=f2003)
to set the -std=f2003 flag for all the files.
- use of set_source_files_properties(file1.f90 PROPERTIES
COMPILE_FLAGS ) to switch off the -std=f2003
flag for the files for which that flag should not be set.
does it look reasonable to you ?
Now my problem. When cmaking my project, I get in one subdirectories
of CMakeFiles a file flags.make that contains the compiler flags. From
that file, it seems that the set_source_files_properties commands
were correctly executed (guessing that the comment for Custom flags is
not an actual comment). But when using nmake in verbose mode, the
custom flags do not appear in the g95 command line. The only ones
displayed are the one set in my set_compiler_flags macro. Is that just
a bug on the display or is there something wrong with my settings ?
thanks a lot
Eric
