I tried manually adding the CoreVideo framework to the project but that didn't help. Probably some recent changes on xcode 16.3 we also had the problem new clang has no std::char_traits<ushort> specialization, and std::char_traits<T> is undefined. Both Ogre and client code should migrate to C++11 std::u16string

Tried again from scratch. Using build_ogre_scripts_v3-0/build_ogre_iOS.sh. Not even building ogredeps works anymore:

Looks like we are not the only ones hit by the new Clang: Bullet zlib issue

[Hotshot5000]

I went full code ninja and hacked a stupid solution just to get over the ogredeps no longer compiling. Patch attached here as I don't think this should be merged anyway.

[Hotshot5000]

Forgot to mention, even though ogredeps now compiles under xcode 16.3 the initial problem still persists as CoreVideo/CVOpenGLESTexture.h not found. When compiling Ogre2-1 even though UIKit.h is also included in iOS/OgreMetalView.h, it is able to find the CoreVideo/CVOpenGLESTexture.h. At first glance the {include_dirs} look similar but I will dig deeper.

Apple has made some big changes in 16.3 it seems changing the clang compiler: Xcode 16.3 release notes.

[Hotshot5000]

It looks like for Ogre3-0 Metal rendersystem xcode chooses to use MacOS sdk instead of the iOS 18 sdk. So CoreVideo/CVOpenGLESTexture.h does not exist as the equivalent for macOS sdk is CoreVideo/CVOpenGLTexture.h. BaseSDK selected in xcode is iOS so I don't understand why it goes after the mac os sdk.

[Hotshot5000]

Finally found the issue:

cmake -D OGRE_CONFIG_THREAD_PROVIDER=0 \
-D OGRE_CONFIG_THREADS=0 \
-D OGRE_BUILD_COMPONENT_SCENE_FORMAT=0 \
-D OGRE_BUILD_SAMPLES2=0 \
-D OGRE_BUILD_TESTS=0 \
-D OGRE_BUILD_RENDERSYSTEM_GL3PLUS=0 \
-D OGRE_BUILD_LIBS_AS_FRAMEWORKS=0 \
-D OGRE_STATIC=1 \
-D OGRE_BUILD_PLATFORM_APPLE_IOS=1 \
-G Xcode ../

GL3Plus rendersystem is disabled but that doesn't mean that the OPENGL_GLU_INCLUDE_DIR OPENGL_INCLUDE_DIR OPENGL_gl_LIBRARY and OPENGL_glu_LIBRARY don't get populated. Once these are populated automatically in the check in CoreVideo.h it does:

Code: Select all

#if __has_include(<OpenGLES/gltypes.h>)
#include <CoreVideo/CVOpenGLESTexture.h>
#include <CoreVideo/CVOpenGLESTextureCache.h>
#endif

And since the gltypes.h are included from the include dirs it includes these also, which don't exist in the (new?) macOS SDK.

So the build script should have:

cmake -D OGRE_CONFIG_THREAD_PROVIDER=0 \
-D OGRE_CONFIG_THREADS=0 \
-D OGRE_BUILD_COMPONENT_SCENE_FORMAT=0 \
-D OGRE_BUILD_SAMPLES2=0 \
-D OGRE_BUILD_TESTS=0 \
