CMAKE_COMPILER_IS_GNUG77

Deprecated since version 3.24: Use the CMAKE_Fortran_COMPILER_ID variable instead.

The CMAKE_COMPILER_IS_* variables were used in early CMake versions before the introduction of 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:

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:

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