I have a situation where I am using wine on Linux and I want to prevent wine from trying to start the interactive debugger. I am using wine version: Wine 20040505 When an executable fails an assertion (assert(0) for example) wine attempts to display a dialog box asking the user if they want to debug the application: Assertion failed: 0, file c:\documents and settings\fsola\my documents\visual studio projects\fake_executable_assertion\fake_executable_assertion\fake_execut able_assertion.cpp, line 9 fixme:ttydrv:TTYDRV_GetBitmapBits (0x58, 0x4039329c, 128): stub fixme:ttydrv:TTYDRV_GetBitmapBits (0x54, 0x4039331c, 128): stub fixme:ttydrv:TTYDRV_GetBitmapBits (0x60, 0x40393d6c, 128): stub fixme:ttydrv:TTYDRV_GetBitmapBits (0x5c, 0x40393dec, 128): stub fixme:win:GetProcessWindowStation (void): stub fixme:user:GetUserObjectInformationA (0x1 1 0x4067b704 12 0x4067b6f8),stub! fixme:ttydrv:TTYDRV_CreateWindow (0x10021): stub fixme:ttydrv:TTYDRV_CreateWindow (0x10022): stub fixme:ttydrv:TTYDRV_CreateWindow (0x10023): stub fixme:ttydrv:TTYDRV_CreateWindow (0x10024): stub fixme:ttydrv:TTYDRV_CreateWindow (0x10025): stub fixme:ttydrv:TTYDRV_CreateWindow (0x10026): stub fixme:ttydrv:TTYDRV_CreateWindow (0x10027): stub fixme:ttydrv:TTYDRV_CreateWindow (0x10028): stub fixme:ttydrv:TTYDRV_CreateWindow (0x10029): stub fixme:ttydrv:TTYDRV_CreateWindow (0x1002a): stub fixme:win:SetWindowTextW cannot set text L"Debug Error!\n\nProgram: ...\\hw\\nvdiag\\testgen\\regress\\test\\fake_executable_assertion.exe\n \n\r\nThis application has requested the Runtime to terminate it in an unusual way.\nPlease contact the application's support team for more information.\r\n\n\n(Press Retry to debug the application)" of other process window (nil) fixme:ttydrv:TTYDRV_GetBitmapBits (0x84, 0x403953e4, 128): stub fixme:ttydrv:TTYDRV_GetBitmapBits (0x80, 0x40395464, 128): stub fixme:dialog:MSGBOX_OnInit task modal msgbox ! Not modal yet. Wine just waits forever at this point. My goal is to just have these jobs die when this happens, so I tried what I thought was the correct solution: I changed the following lines in my ~/.wine2004/system.reg: FROM: [Software\\Microsoft\\Windows NT\\CurrentVersion\\AeDebug] 1094757697 "Auto"="0" "Debugger"="winedbg %ld %ld" TO: [Software\\Microsoft\\Windows NT\\CurrentVersion\\AeDebug] 1094757697 "Auto"="1" "Debugger"="xxxxxxxx %ld %ld" My understanding is that this should do two things: 1) Changing "Auto" to "1" should cause wine NOT to put up the dialog box asking if the user wants to debug the application. 2) Changing "Debugger" to "xxxxxxxx" should cause wine to fail to find and launch the debugger. BUT, I see absolutely no change in the behavior. I was able to verify that other changes to this systen.reg file are being picked up by changing one of the font entries, and then running with all debug channels enabled. But I never saw anything in the debug output that indicated that wine was using the AeDebug entry at all. To be safe I also changed the same entries in ~/.wine2004/drive_c/inf/wine.inf TO: [Debugger] HKLM,Software\Microsoft\Windows NT\CurrentVersion\AeDebug,"Debugger",,"xxxxxx %ld %ld" HKLM,Software\Microsoft\Windows NT\CurrentVersion\AeDebug,"Auto",,"1" SO, my questions are: 1) Is this the only way to disable the debugger (more importantly to stop wine from asking the user if they want to debug the application)? 2) Am I doing something wrong? (am I changing the wrong file?) 3) Any ideas why this is not doing what I expect??? Any help would be greatly appreciated since I am out of ideas at this point. Thanks in advance, - Hank
