| Summary | 0002579: (master) cmake always prints "Building Spring for 32bit environment" when march is set | ||||
| Description | when doing a "cmake ." as default i've march="" when setting it to march=athlon64, i get this: cmake . -- Building Spring for 32bit environment -- Building Assimp with flags -march=athlon64 -msse -mfpmath=sse -frounding-math -mieee-fp -pipe -fno-strict-aliasing -fvisibility=hidden -fvisibility-inlines-hidden -pthread | ||||

looks like this is not the cause of desyncs :-/ |

Relevant parts of CMakeLists.txt: if (CMAKE_SIZEOF_VOID_P EQUAL 8) message (STATUS "Building Spring for 64bit environment") set (MARCH_FLAG CACHE STRING "CPU optimization (use i686 for generic optimization)") else (CMAKE_SIZEOF_VOID_P EQUAL 8) message (STATUS "Building Spring for 32bit environment") set (MARCH_FLAG "i686" CACHE STRING "CPU optimization (use i686 for generic optimization)") endif (CMAKE_SIZEOF_VOID_P EQUAL 8) followed by if ($ENV{CXX} MATCHES "icpc") ... else ($ENV{CXX} MATCHES "icpc") if (MARCH_FLAG) set (CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -march=${MARCH_FLAG}") endif (MARCH_FLAG) set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${SSE_FLAGS}") # SSE1 if (MINGW) set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -mthreads") endif (MINGW) set(CXX_FLAGS_DEBUG_ADDITIONAL "") endif ($ENV{CXX} MATCHES "icpc") If you call cmake with -DMARCH_FLAG=blabla, then that overrides the auto-detection for the entire project, but it still runs and so you always get the "building Spring for 32bit environment" message (on a 32bit system). You can check this via "make spring VERBOSE=1". |
