From 930bb0cd37ca9d4e522411e06defbc3c52ba8724 Mon Sep 17 00:00:00 2001 From: Alexander Neundorf Date: Mon, 2 Jul 2007 13:29:36 -0400 Subject: ENH: remove support for presetting CMAKE_SYSTEM_INFO_FILE, CMAKE_SYSTEM_AND_C_COMPILER_INFO_FILE, CMAKE_SYSTEM_AND_CXX_COMPILER_INFO_FILE, CMAKE_SYSTEM_AND_C_COMPILER_AND_PROCESSOR_INFO_FILE and CMAKE_SYSTEM_AND_CXX_COMPILER_AND_PROCESSOR_INFO_FILE Instead of presetting these variables to arbitrary filenames, users should set up CMAKE_SYSTEM_NAME and the compilers correctly and also create a Platform/ directory so these files will all follow the official cmake style, which should make it easier to understand and debug project which have their own platform/toolchain support files. -remove support for a suffix to MS crosscompilers, since this is not (yet) supported by cmake and might confuse users Alex --- Modules/CMakeCInformation.cmake | 34 ++++++++++++---------------- Modules/CMakeCXXInformation.cmake | 33 +++++++++++---------------- Modules/CMakeDetermineCCompiler.cmake | 16 +------------ Modules/CMakeDetermineCXXCompiler.cmake | 16 +------------ Modules/CMakeSystemSpecificInformation.cmake | 4 +--- Tests/CMakeTests/DummyToolchain.cmake | 2 +- Tests/CMakeTests/ToolchainTest.cmake.in | 5 ---- 7 files changed, 31 insertions(+), 79 deletions(-) diff --git a/Modules/CMakeCInformation.cmake b/Modules/CMakeCInformation.cmake index 4d4e52a..fec8389 100644 --- a/Modules/CMakeCInformation.cmake +++ b/Modules/CMakeCInformation.cmake @@ -19,30 +19,24 @@ IF(CMAKE_COMPILER_IS_GNUCC) ENDIF(CMAKE_COMPILER_IS_GNUCC) -IF(CMAKE_SYSTEM_AND_C_COMPILER_AND_PROCESSOR_INFO_FILE) -
