CMAKE_COMPILER_IS_GNUG77

.. deprecated:: 3.24

Use the :variable:CMAKE_Fortran_COMPILER_ID <CMAKE_<LANG>_COMPILER_ID> variable instead.

The CMAKE_COMPILER_IS_* variables were used in early CMake versions before the introduction of :variable:CMAKE_<LANG>_COMPILER_ID variables in CMake 2.6.

The CMAKE_COMPILER_IS_GNUG77 variable is set to boolean true if the Fortran compiler is GNU.

Examples ^^^^^^^^

In earlier versions of CMake, the CMAKE_COMPILER_IS_GNUG77 variable was used to check if the Fortran compiler was GNU:

.. code-block:: cmake

if(CMAKE_COMPILER_IS_GNUG77) # GNU Fortran compiler-specific logic. endif()

Starting with CMake 2.6, the CMAKE_Fortran_COMPILER_ID variable should be used instead:

.. code-block:: cmake

if(CMAKE_Fortran_COMPILER_ID STREQUAL "GNU") # GNU Fortran compiler-specific logic. endif()
