Wine, Office, and the antitrust settlement
by Dan Kegel 11 Dec '01

11 Dec '01

I'm proposing that Wine be part of the settlement of the Microsoft antitrust trial. See http://www.kegel.com/remedy.html Comments welcome. I have a few questions for Wine developers, especially the good folks at Codeweavers and Transgaming: 1. How much would it cost to achieve full support for Office 2000 in Wine? 2. Is it true that Office uses undocumented Windows APIs? If so, how many? Are they a significant part of the challenge of supporting Office? Thanks, Dan Kegel dank(a)kegel.com

On Solaris fstab is vfstab, and mtab is mnttab, parsing these files is no good unless it is done in some portable way. (Not that smbfs even works on Solaris) I would think that persistent share selection should be saved in the registry and accessed through smbclient rather than smbfs, then smb shares would work for all OSs supporting Samba, not just those supporting smbfs. IMHO There are already too many linux centrix assumptions in wine, please, lets not add any more . Bob

Getting Started
by Oliver Sampson 11 Dec '01

11 Dec '01

Howdy, I'm trying to get started with Wine development, and I figured the best way would be to CVS the code and install it. I CVSed the code, configured, did a 'make depend', 'make', and a 'make install'. When I try to run wine, I get a message that libntdll.so wasn't found. So I found it in /usr/lib/libntdll.so. is there something in the initial setup config that didn't work correctly? FWIW, I can rpm the wine-cvs-unstripped rpm just fine, and it works well. (The install process and the program.) Any ideas how to get this working from my cvs directory? Thanks, ==================================================== Oliver Sampson olsam(a)quickaudio.com http://www.oliversampson.com

RE: Wine, Office, and the antitrust settlement

> I'm proposing that Wine be part of the settlement of the > Microsoft antitrust trial. See > http://www.kegel.com/remedy.html > Comments welcome. Well. I think the paragraph below is far to much to ask and I don't think anti-trust law can force Microsoft to do this. >From http://www.kegel.com/remedy.html: < Contracting with a Third Party to Enhance Wine to Support < Microsoft Office. "Within 60 days of entry of this Final Judgement, < Microsoft must contract with one or more outside firms to enhance the < Open Source Windows Emulator WINE to be able to install and run < Office 2000 under Linux. The work shall continue,with new releases < of Wine occurring every 60 days, until completed, or until the expenses < incurred by the outside firms reach 2 percent of the total development < and marketing costs of Office 2000. Furthermore, as soon as practicable, < but in no case later than 60 days prior to the date each new version of < Office becomes commercially available for use with a Windows Operating < System Product, Microsoft shall again contract with one or more outside < firms to enhance the Open Source Windows Emulator WINE to be able to < install and run the new version of Office under Linux. The work shall < continue, with new releases of Wine occurring every 60 days, until < completed, or until the expenses incurred by the outside firms < reach 2 percent of the total development and marketing costs < of the new version of Office. What is perhaps more realistic to require IMHO that Office and other Microsoft applications shouldn't crash or behave in a inconsistant way just because some odd feature in some API call is not available. Instead it should say, sorry can't do that not supported in the OS. This would prevent Microsoft from sabotaging Wine as well preventing users of say Windows 95 from needlessly having to upgrade. Yes, I'm aware of that Microsoft of course not can check every API call and have a fallback for each function, but groups of features that is potentially unneeded for basic features in Office like: 1. DirectX 2. MAPI 3. .NET 4. DAO 5. "Sound" 6. "Networking" 7. <Insert whatever favorite technology from Microsoft that you like> shouldn't be required to do normal stuff in Office. > I have a few questions for Wine developers, especially > the good folks at Codeweavers and Transgaming: > > 1. How much would it cost to achieve full support for > Office 2000 in Wine? That is an impossible question to answer. > 2. Is it true that Office uses undocumented Windows APIs? > If so, how many? Are they a significant part of the > challenge of supporting Office? Yes. But I don't rember which ones right know but there are quite a lot of undocumented API calls used by a lot of different programs. Perhaps somebody else on the list can be more specific.

Where do I start on DDX_Radio?
by Bill Medland 08 Dec '01

08 Dec '01

Any chance of a quick pointer on this? I have a dialog containing a group of radio buttons, managed using DDX_Radio etc. On windows the DDX_Radio sets the correct button. However under WINE it always seems to set the first button of the group. Does anyone know what part of the code I should even be investigating (i.e. where is the dialog management code) Bill
