ogre: Building fails on MacOS Mojave due to linker errors

System Information

Ogre Version: 1.11.2 stable (from source)
Operating System / Platform: macOS 10.14 (Mojave)
RenderSystem: OpenGL (looking at the linker error, at least)

Detailled description

I downloaded the latest source today, ran cmake -GXcode .. in a build subdirectory. Changing the architecture to x86_64, I built the project. Compiling apparently runs through, but I get linker errors afterwards.

Below is the complete log of the linking errors.

I finally got ogre to build on macOS High Sierra 10.13.6 with Xcode 10.1.

I’m just a weekend coder, so I’m not sure exactly what got things working, but I think a combination of these edits to CMakeLists.txt did the trick:

#include(CheckTypeSize)
#CHECK_TYPE_SIZE("void*" OGRE_PTR_SIZE BUILTIN_TYPES_ONLY)
#if (OGRE_PTR_SIZE EQUAL 8)
#  set(OGRE_PLATFORM_X64 TRUE)
#else ()
#  set(OGRE_PLATFORM_X64 FALSE)
#endif ()

# compile for 64bit system
set(OGRE_PLATFORM_X64 TRUE)

and

-        set(CMAKE_OSX_ARCHITECTURES "${ARCHS_STANDARD_32_64_BIT}")
+  #      set(CMAKE_OSX_ARCHITECTURES "${ARCHS_STANDARD_32_64_BIT}")
+	      set(CMAKE_OSX_ARCHITECTURES "${ARCHS_STANDARD_64_BIT}")
      else()
-        set(CMAKE_OSX_ARCHITECTURES "$(ARCHS_STANDARD_32_64_BIT)")
+  #      set(CMAKE_OSX_ARCHITECTURES "$(ARCHS_STANDARD_32_64_BIT)")
+	      set(CMAKE_OSX_ARCHITECTURES "${ARCHS_STANDARD_64_BIT}")

Then I changed these to get a working application:

option(OGRE_STATIC "Static build" TRUE)
option(OGRE_ENABLE_PRECOMPILED_HEADERS "Use precompiled headers to speed up build" FALSE)

Hope this helps the next person trying to get ogre to compile on a recent macOS!

setting CMAKE_OSX_ARCHITECTURES=x86_64 should fix this
