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.
