Description Brendan Duncan 2009-09-10 13:18:13 EEST

The flags
-Wl,--gc-sections -Wl,-O1 -Wl,--hash-style=gnu
are not supported by the OSX version of GCC.

Also, these flags should be put into CMAKE_SHARED_LINKER_FLAGS instead of
CMAKE_CXX_FLAGS.

In CMakeLists.txt, replace the CMAKE_CXX_FLAGS_RELEASE line with

IF(APPLE)
    set(CMAKE_CXX_FLAGS_RELEASE "-Wall -fvisibility=hidden
-fvisibility-inlines-hidden -Os -finline-limit=600 -ffunction-sections
-fomit-frame-pointer -fno-default-inline -fconserve-space -fno-enforce-eh-specs
-fno-threadsafe-statics -fno-implicit-inline-templates -DNDEBUG
-DBOOST_PYTHON_NO_PY_SIGNATURES")
ELSE(APPLE)
   set(CMAKE_CXX_FLAGS_RELEASE "-Wall -fvisibility=hidden
-fvisibility-inlines-hidden -Os -finline-limit=600 -ffunction-sections
-fomit-frame-pointer -fno-default-inline -fconserve-space -fno-enforce-eh-specs
-fno-threadsafe-statics -fno-implicit-inline-templates -DNDEBUG
-DBOOST_PYTHON_NO_PY_SIGNATURES -Wl,--gc-sections -Wl,-O1
-Wl,--hash-style=gnu")
ENDIF(APPLE)
