Summary0007389: Fortran flags assigned to C compiler when generating Xcode
DescriptionCurrently CMake does not support Fortran language for Xcode, as Xcode itself does not support it. However it is possible to generate an Xcode project where C files are compiled but not Fortran files. In this case CMake assigns to the C compiler the flags defined for the fortran compiler, and therefore also C compilation breaks. This should not happen. Please consider the following example of CMakeLists.txt

Cmake_Minimum_Required(VERSION 2.6)
Set(CMAKE_Fortran_COMPILER gfortran)
Set(CMAKE_Fortran_FLAGS "-fno-second-underscore")
Add_Executable(hello hello.c sub.F)

Xcode generation works, however the -fno-second-underscore flag ends up in the CFLAGS and therefore C compilation fails.
Additional InformationThe files mentioned before are immaterial, however for completeness here they are

[.../Users/fca/cmaketest] cat sub.f
      subroutine sub
      print *, 'Hello World from Fortran!'

[.../Users/fca/cmaketest] cat hello.c
#include <stdio.h>

void sub_();
int main () {printf(" Hello World from C!\n"); sub_(); return 0;}
