Looking at the errors, it seems that the code is missing some include headers. For example, IUnknown_QueryInterface_Proxy is in unknwnbase.h and IRpcStubBufferVtbl is in objidlbase.h.Try to add `import "unknwn.idl";` in the IDL file that you want to compile. If you have a simple, minimal, reproducible code example[1] please provide it. It will help to debug the issue quickly. And for msys2, check if you've installed mingw-w64-x86_64-toolchain (i686 for 32bit) group package properly. [1]: https://stackoverflow.com/help/minimal-reproducible-example Hi, although I do not have unknwn.idl directly imported, it is imported through the oaidl.idl. The same (from midl) generated code compiles fine with Embarcaderos compiler, which uses its own headers. They are nearly identical to those from the windows sdk. My minimum example is attached, when I ran the response file with "MIDL Compiler Version 8.01.0622" the initial error is: C:/msys64/mingw32/i686-w64-mingw32/include/_mingw.h(581) : error MIDL2025 : syntax error : expecting a type specification or a storage specifer or a type qualifier near "__inline__" I've attached the patch to fix this. With gcc dlldata.c proxy.c example_i.c I still get 'IUnknown_QueryInterface_Proxy' undeclared here (not in a function) Adding -DWIDL_C_INLINE_WRAPPERS -DCOBJMACROS spams a lot of similar errors: c:/msys64/mingw32/i686-w64-mingw32/include/unknwnbase.h:152:1: error: multiple storage classes in declaration specifiers 152 | static FORCEINLINE HRESULT IUnknown_QueryInterface(IUnknown* This,REFIID riid,void **ppvObject) { Precompiled (also attached) this results to static extern __inline__ __attribute__((__always_inline__,__gnu_inline__)) HRESULT IUnknown_QueryInterface(IUnknown* This,const IID *const riid,void **ppvObject) { Compiling it with g++ results in the same errors I've mentioned in the initial message. When I compile the Code with bcc32c (the Clang based Embarcadero Compiler) it compiles (and runs, because that's what we use right now). I've also attached the command line for bcc32c which is rather long. You may notice -DWIN32 and -DREGISTER_PROXY_DLL, I've also tried to add that to the gcc call which doesn't change anything. With widl the wine headers are obviously still missing. There is no package called "mingw-w64-x86_64-toolchain", so I assume you just meant the toolchain. I've mingw32/mingw-w64-i686-{gcc|gdb|make|tools-git} and many more. The same for 64 Bit, but right now I focused on 32 Bit. Are there any other packages I need? I think my compiler is running fine, because I've already compiled Qt, LLVM, qbs, QtCreator, and some other programs.
