debugging - why my app doesn't run under Wine

pnswdv · Post by **pnswdv** » Fri Jun 01, 2012 4:58 pm

I am running Linux Mint with Wine installed, and am testing a suite of Windows applications which I wrote & have control over, and am trying to determine why one of them doesn't run under Wine and see if there are any modifications I can make to it to make it work. The symptoms are a follows:

My application is a server/router written in C++/MFC which implements a proprietary protocol on top of TCP/IP. When I first tried running it, I received a WMI error, so I used Winetricks to install WMI. The WMI installation reported success, I rebooted my machine and attempted running it again. This time there is no error message, but I just get a spinning cursor for about 10 seconds and then the cursor returns to the pointer. Checking a logfile that my app creates indicates that it merely exits without ever performing it's initialization.

I am quite unfamiliar with linux so I do not know where to look for hints as to what may be going wrong. Several of my other applications run fine, so Wine seems to be working properly on my machine. Suggestions, please!

Hi,

if your app needs access to TCP/IP ports < 1024 and you are running as regular user (running wine as root is not recommended), you will need to do something like described in http://unix.stackexchange.com/questions ... below-1024

The simpler alternative would be to choose ports above 1024, if you can.

Furthermore you might need to do "winetricks vcrun6", as wine doesn't implement mfc.

If it still doesn't work, upgrade to latest wine version, run from command line and post terminal output.

Thanks for your suggestions! However, I have already loaded the MFC package you suggested, and I do not use ports below 1024.

I attempted to run from the command line and received the following information:

fixme:ole:CoInitializeSecurity ((nil),-1,(nil),(nil),0,3,(nil),0,(nil)) - stub!
err:ole:ProxyCliSec_SetBlanket (0x138b64,10,0,(null),3,3,(nil),0x0): stub
err:ole:CoSetProxyBlanket -- failed with 0x800004001
Could not set proxy blanket. Error code = 0x800004001

So that looks like a pretty good clue, if only I understood it! I went to winetricks to see if I could find anything related to OLE but didn't.

What version of Wine are you using? (What does wine --version output?)

What WMI functions do you call?

Can you look from your app's side (possibly using a debugger)
to see what's failing?
Alternately, a +relay,+seh log might be illuminating.

What app is this, and is a demo version downloadable somewhere?

Wine version is 1.4

I am a linux novice so I don't know how to create the "+relay,+seh" log you refer to. I tried including them as command line arguments to Wine but that didn't work.

The application can be downloaded from http://xxtinc.com/software-downloads.html The download you would want is the first one (xxMWD-PCSuite V02.10 Setup.zip) This will install a number of applications, but the one in question is the "xxNETserver" application. This is all special-purpose code to support our company's hardware products, and when you install it, it will ask you several questions that will likely make you say "huh?". You can just accept the default values for everything, but when you get to the one asking if you are going to use an RS232 port to connect to our hardware you should just say no. It might be simpler for you if I were to just send you the EXE in question.

In the meantime, following is the source for the code which contains the failing call to "CoSetProxyBlanket". Thanks for your help!

Code: Select all

Thanks for the info.

See

and the one right below it

I created the log file you requested and zipped it up. However, I don't see a way to attach it to this message. Am I supposed to be creating some sort of bug report somewhere else for this issue?

Thanks!

Put it on pastebin.com and link here.

Log file is too large for pastebin. The zip file is a reasonable size but I don't appear to be able to put a zip on pastebin.

Posted the log file on a web server at http://tinyurl.com/6ochbkk

The key bit of that log is

003b:Call ole32.CoSetProxyBlanket(00149b34,0000000a,00000000,00000000,00000003,00000003,00000000,00000000) ret=0043da13

003b:Ret ole32.CoSetProxyBlanket() retval=80004001 ret=0043da13

SetBlanket is a stub that always returns failure:
http://source.winehq.org/source/dlls/ol ... hal.c#L579

You might hack the stub to pretend to succeed, and see if your app
gets further.

Thanks for the info! I will try modifying my source to ignore the error return from CoSetProxyBlanket() and see what happens...
