# MoltenVK builds compatible with osxcross Official Khronos [MoltenVK releases](https://github.com/KhronosGroup/MoltenVK/releases/) are incompatible with current osxcross versions due to Xcode automatically using the `-fobjc-msgsend-selector-stubs` optimization. The linker used by osxcross doesn't seem to support these yet, even when compiling against Apple LLVM. See this upstream issue for details: - https://github.com/KhronosGroup/MoltenVK/issues/1756 This repository simply does it own builds of MoltenVK with these flags added to disable the optimization: ``` -fno-objc-msgsend-selector-stubs -Wno-unused-command-line-argument ``` That's the only difference with Khronos' builds.
