| Summary | 0014862: CMake and Ninja - check for Fortran optionally | ||||||||
| Description | Projects such as Eigen attempt to check for a working Fortran compiler, the act of probing for a working Fortran compiler causes configure to fail. This currently means that we are unable to use Ninja to build Eigen. I think the Ninja generator should at least exit more gracefully so that C/C++ projects with optional Fortran code are able to continue. This could be as simple as CMakeTestFortranCompiler.cmake returning failure on any attempt to test Fortran with the Ninja generator. | ||||||||
| Steps To Reproduce | Get Eigen, attempt to build it, http://eigen.tuxfamily.org/ [^] is the main site, using the Ninja generator I get the following failed configure. | ||||||||

My thought is to move all of the hard-error cases down to when Ninja actually tries to generate a build rule for a Fortran object file since this is where Ninja actually has the issue (determining its dependencies reliably). A more useful error message could be used as well (which object file/target is the culprit and mentioning that Ninja can't get dependencies right). Crazy idea I'm okay with not doing (but proposing so that anyone suggesting such a thing can be pointed here): having a CMAKE_NINJA_FORTRAN_I_KNOW_WHAT_IM_DOING_GIVE_ME_THE_ROPE variable to skip the check. |

Approaching this as a CMake user that mainly focuses on C/C++, but often has need of Fortran in projects, I would like a simple way of asking if I have a usable Fortran compiler and optionally doing stuff if so. I have no strong feelings on how that should be done, but it is a reasonably common use case in scientific computing to make it worthwhile supporting. If I have a real Fortran project I know that life will be much easier using a Makefile based generator and I will tend to prefer that, so the variable really would be of minimal practical use to many of us. |

FWIW, CMake itself checks for Fortran support like this: http://cmake.org/gitweb?p=cmake.git;a=blob;f=Tests/CheckFortran.cmake;hb=v3.0.0-rc3 [^] in order to enable tests for it. |

I have a branch on stage which delays the Fortran+Ninja error until a target with a Fortran compilation target is detected. This way you can ask for Fortran and do whatever, just not "add_library(tgt fortran.f90)". dev/ninja-fortran-erroring |
