Betreff: Re: [Mingw-w64-public] Using midl/widl with MinGW
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.

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.

Am I doomed to use ITypeInfo and IDispatch for IDWriteTextLayout objects in C code? You can't compile it as C it looks like, as is. For Wine this header is built from dwrite.idl (that does not exist in SDK), and widl was made to handle such cases by renaming vtable field of overloaded method. Second part of this quirk is that inline wrappers like IDWriteTextLayout_GetFontCollection() are only emitted for overloaded variants. It gets worse in newer dwrite headers, when same interface is using overloaded variants in its own methods list. I didn't get the part about ITypeInfo/IDispatch, how are do you plan to apply it for dwrite that doesn't use automation-capable objects?
