[Bf-committers] Compile Blender with cycles with Debug configuration

[tom]

Hi Campbell:
   I added a print and found the cycles CMakeLists.txt has done it, somehow, the Xcode does not take it and cause the link error.
 
   The added print line is like this:
—————————————
--- a/intern/cycles/blender/CMakeLists.txt
+++ b/intern/cycles/blender/CMakeLists.txt
@@ -57,6 +57,7 @@ blender_add_lib(bf_intern_cycles "${SRC}" "${INC}" "${INC_SYS}")
 # avoid link failure with clang 3.4 debug
 if(CMAKE_C_COMPILER_ID MATCHES "Clang" AND NOT ${CMAKE_C_COMPILER_VERSION} VERSION_LESS '3.4')
        set(CMAKE_CXX_FLAGS_DEBUG "${CMAKE_CXX_FLAGS_DEBUG} -gline-tables-only")
+       message("in cycles CMakelists.txt, CMAKE_CXX_FLAGS_DEBUG = ${CMAKE_CXX_FLAGS_DEBUG}")
 endif()
—————————————
   And the observed output is:
...
in cycles CMakelists.txt, CMAKE_CXX_FLAGS_DEBUG = -fno-strict-aliasing -g -gline-tables-only
…
—————————————
  The compiler flag has -gline-tables-only as we expect, the problem may be caused by Xcode NOT translating it correctly to its project settings,
  it has to take more investigations to know why.
