Unimplemented KERNEL32.dll function FindFirstFileNameW

[turtleizzy]

Wechat (3.9.11.25) on wine (9.17) halts randomly, and the culprit boils down to an unimplemented function call in Kernel32.dll.

Code: Select all

wine: Call from 00006FFFFFC6DC18 to unimplemented function KERNEL32.dll.FindFirstFileNameW, aborting

I am not familiar with Windows API but this function looks frequently used judging by its name.
Has anyone had this issue before?

In Micrografx Picture Publisher 7 & 8 the file requester crashes only after entering another directory. This may be related because it happens when it should display folder content.

I am also experiencing the same issue described in this thread. Here are the details of my situation:

- Wine version: 9.0
- Operating System: Ubuntu 24.04
- Application: WeChat 3.9.8.25
- Error message: Unimplemented KERNEL32.dll function FindFirstFileNameW

I've searched on the Internet, and the only related thread is a Chinese post (http://www.qinmigpt.com/post/1149.html) where the author mentioned that he implemented this function himself, but did not provide the source code. It is still a bit too difficult for me to handle this situation, so any help from the forum would be appreciated. Thank you!

Hi,

If you know how to compile wine, could you try if patch here fixes the bug for you?

I have tested this patch over wine-9.18 src and Wechat 3.9.12.15 (with the help of #2).
The bug seems to be resolved.
I can see proper FIXME debug logs when FindFirstFileNameW was called and the program seems to function normally.
Thank you so much for all your help!

Code: Select all

0368:fixme:file:FindFirstFileNameW (L"C:\\users\\abc\\Documents\\WeChat Files\\abcd\\FileStorage\\MsgAttach\\....", 0, 0000700FC47DEA50, 0000700FC47DEB00): stub!

Hi, thanks for testing. A similar patch is upstreamed and will be included in next upcoming release (wine-9.19) so you can try that out once it' released

That will be nice, as my attempt to compile Wine failed and I failed to find why. Looking forward to update to 9.19.

I can confirm this issue has been resolved since wine-9.19. Wechat now works normally under wine-9.19 and 9.20.

Also for anyone concerned, Wechat has released its native Linux version (finally) so it might not be necessary to use the Windows version anymore.
