[CMake] CMake 2.6.2, Xcode and Fortran...

[Carminati Federico]

Hello Bill,
    Thanks for your mail. I can see you are in the user support  
business too ;-) "Please make a simple example". OK, you are right.  
Here what I have done. I have made the simplest possible example (see  
files attached). I installed the latest version from cvs and now I  
have had some success:

- The "bug" where fortran flags "percolated" through C when generating  
Xcode is still there. This is normal as it is still open in the bug  
tracker. Would be nice to see this fixed if possible.

- However, the other problem, i.e. gfortran failing verification seems  
to be gone (miracle?) I can generate an Xcode project and gfortran is  
correctly verified even if the plugin is present.

- Now things are still NOT completely ok, because I have the error  
message

warning: no rule to process file '/Users/fca/cmaketest/sub.F' of type  
sourcecode for architecture i386

However this just happens because cmake does not put the files in the  
right place. The file is

Test->Sources->hello

and therefore it has file type "sourcecode", which is generic and does  
not tell Xcode what to do with it

If I just move it by hand into the right place

Test->Sources->hello->Source Files

Xcode is smart enough to give it the type sourcecode.fortran and  
everything works correctly.

So the question is now, would it be possible for CMake to put Fortran  
files in the "right" place treating them as source files? In this case  
it will be up to Xcode to see whether it can make use of the info or  
not, but at least they will be treated as source files. Thanks and  
best regards,
