From 393a45e2e1fa2f0d9657d4a686257d828cd918e4 Mon Sep 17 00:00:00 2001 From: Nicolas Bock Date: Mon, 2 Feb 2015 17:07:04 -0700 Subject: CheckFortranCompilerFlag: Add module to check Fortran flag existence Copy the CheckCCompilerFlag module and replace 'C' with 'Fortran'. Also update the common patterns module to match some Fortran compiler messages. --- Help/manual/cmake-modules.7.rst | 1 + Help/module/CheckFortranCompilerFlag.rst | 1 + Modules/CMakeCheckCompilerFlagCommonPatterns.cmake | 5 +- Modules/CheckFortranCompilerFlag.cmake | 66 ++++++++++++++++++++++ 4 files changed, 71 insertions(+), 2 deletions(-) create mode 100644 Help/module/CheckFortranCompilerFlag.rst create mode 100644 Modules/CheckFortranCompilerFlag.cmake diff --git a/Help/manual/cmake-modules.7.rst b/Help/manual/cmake-modules.7.rst index db56010..76058f9 100644 --- a/Help/manual/cmake-modules.7.rst +++ b/Help/manual/cmake-modules.7.rst @@ -22,6 +22,7 @@ All Modules /module/CheckCXXSourceCompiles /module/CheckCXXSourceRuns /module/CheckCXXSymbolExists + /module/CheckFortranCompilerFlag /module/CheckFortranFunctionExists /module/CheckFortranSourceCompiles /module/CheckFunctionExists diff --git a/Help/module/CheckFortranCompilerFlag.rst b/Help/module/CheckFortranCompilerFlag.rst new file mode 100644 index 0000000..58bf6ec --- /dev/null +++ b/Help/module/CheckFortranCompilerFlag.rst @@ -0,0 +1 @@ +.. cmake-module:: ../../Modules/CheckFortranCompilerFlag.cmake diff --git a/Modules/CMakeCheckCompilerFlagCommonPatterns.cmake b/Modules/CMakeCheckCompilerFlagCommonPatterns.cmake index 19b2bbc..3141d60 100644 --- a/Modules/CMakeCheckCompilerFlagCommonPatterns.cmake +++ b/Modules/CMakeCheckCompilerFlagCommonPatterns.cmake @@ -21,9 +21,9 @@ macro (CHECK_COMPILER_FLAG_COMMON_PATTERNS _VAR) set(${_VAR} - FAIL_REGEX "unrecognized .*option" # GNU + FAIL_REGEX "[Uu]nrecogni[sz]ed .*option" # GNU, NAG FAIL_REGEX "unknown .*option" # Clang - FAIL_REGEX "ignoring unknown option" # MSVC + FAIL_REGEX "ignoring unknown option" # MSVC, Intel FAIL_REGEX "warning D9002" # MSVC, any lang FAIL_REGEX "option.*not supported" # Intel FAIL_REGEX "invalid argument .*option" # Intel @@ -35,6 +35,7 @@ macro (CHECK_COMPILER_FLAG_COMMON_PATTERNS _VAR) FAIL_REGEX "command option .* contains an incorrect subargument" # XL FAIL_REGEX "not supported in this configuration. ignored" # AIX FAIL_REGEX "File with unknown suffix passed to linker" # PGI + FAIL_REGEX "[Uu]nknown switch" # PGI FAIL_REGEX "WARNING: unknown flag:" # Open64 FAIL_REGEX "Incorrect command line option:" # Borland FAIL_REGEX "Warning: illegal option" # SunStudio 12 diff --git a/Modules/CheckFortranCompilerFlag.cmake b/Modules/CheckFortranCompilerFlag.cmake new file mode 100644 index 0000000..53fd8d6 --- /dev/null +++ b/Modules/CheckFortranCompilerFlag.cmake @@ -0,0 +1,66 @@ +#.rst: +# CheckFortranCompilerFlag +# ------------------------ +# +# Check whether the Fortran compiler supports a given flag. +# +# CHECK_Fortran_COMPILER_FLAG( ) +# +# :: +# +# - the compiler flag +# - variable to store the result +# Will be created as an internal cache variable. +# +# This internally calls the check_fortran_source_compiles macro and +# sets CMAKE_REQUIRED_DEFINITIONS to .
