wine can't load my custom build-in dll and report "call to unimplemented function" - wine

Question

I can't login WINEHQ Bugzilla, so I ask here and this is the requirement:
We have a windows app which we have exe source code, and it used ATL. The dlls the exe depends require some special device, but mostly they have linux version. Now we need to port the windows app to linux.
My finally try: write a middle dll to wrap some lib which already is cross platform, the exe will call new middle dll, and I name the middle dll is "WINE custom build-in dll". CUSTOM means I compile this dll.so standalone by winemaker. Everything is fine until run it under wine64, the command line in linux shell:
wine64 portsome.exe
here is the output:
wine: Call from 0x7bc5eeec to unimplemented function wrapsome.dll.wrap_SOME_GetVersion, aborting

Here is my question:
how do I compile a wine custom build-in dll to make windows native app can call its function when running, is it need to generate a fake dll by winebuilder?
Detail steps I working for port windows app to linux:
1. find the special dll which need contact with hardware directly, like CUDA, dongle access.
2. make a wrap dll, change the exe code to call this wrap dll function, and the wrap dll then call hardware aware dll.
3. create "wrapsome.spec" file with https://wiki.winehq.org/Winelib_User%27s_Guide#The_Spec_file requirements.
4. copy the wrap code to Ubuntu 16.04, switch to wrap code source directory and run below command in shell:
winemaker --dll --nosource-fix -DWRAPSOME_EXPORTS -I../deps/hdaware -L../deps/hdaware -lhdaware .
then I got the "Makefile" file and I append -fPIC to LDFLAGS.
5. continue to run "make", yea, I got the wrapsome.dll.so, and I copy it to wine build-in dlls directory.
6. finally I failed to run "wine64 portsome.exe", the question is mentioned above.
wine report "unimplemented function wrapsome.dll.wrap_SOME_GetVersion", I even confirmed with nm wrapsome.dll.so, and here is its output:

Notice: I have dismissed some word with common ones as it is not good to show to the public.
I even read the wine source code in github https://github.com/wine-mirror/wine/blob/fdac39f697e049ead215b164bfe6953269ffa7be/dlls/ntdll/loader.c#L660, it seems
exports = RtlImageDirectoryEntryToData( imp_mod, TRUE, IMAGE_DIRECTORY_ENTRY_EXPORT, &exp_size );
can't export the warpsome.dll.so file symbol table which I compile by winemaker+winegcc tool chain.

Answer 1

I changed the wrapsome.spec file to this content:
# stdcall wrap_SOME_InitAwareSDK(ptr) wrap_SOME_InitAwareSDK
# stdcall wrap_SOME_UninitAwareSDK(ptr) wrap_SOME_UninitAwareSDK
# stdcall wrap_SOME_GetVersion() wrap_SOME_GetVersion
and make again, then cp to wine dlls directory, it works! And I known there is no need to change the exe link to warp dll in windows, just build a dll.so with extract the same export name which need by exe, it should works too. I will try it later.
