Actually you all bring up rather interesting points with regards to Vector NTI as: (a) It pretty much ships with almost every Microsoft redistributable needed (e.g., MDAC, Windows Script, MFC71, etc.) and installs them on its installation _except_ MFC42 (not sure why this oversight and if this would break it on some native system, although I _believe_ it installed correctly on my plain vanilla Win98 VMWare installation, but I would have to double check for sure). (b) If the licenses for those DLLs/redistributables are the same as you suggest for DirectX, this would mean they couldn't ever say they support Wine (but I'm not sure whether or not the licenses are). Anyway, seeing it work "gold" on Wine still wouldn't be a bad thing in either case and certainly Vector NTI is not the only program that needs good winhelp support. Misha

Monster and Me in wine
by Nguyễn Thành Trung 04 Sep '07

04 Sep '07

Hi ! I'm playing Monster and Me (www.monsterandme.com) in wine. In wine 0.9.7, there's a small bug when login, but every else work fine. In other newer versions of wine, login screen works fine, the game's performance is better - nearly like in windows. But there's a bug when talking with NPC make me can't play this game. Can any 1 find and fix this plz? Thanks !

Dan Hipschman has been improving widl for some time, but his internship is up in a couple months, and I'm sure he'd love some help. 2) crypt32 / wintrust. Lots of apps need these. Juan Lang has been working on these this summer, but his internship is up at the end of the month, and I'll bet he has a big todo list. 3) gdiplus. Evan Stade did a great job getting this going, and several apps that need it now run, but there's lots left to do. 4) msvcrt. Believe it or not, our bugzilla lists 21 or so bugs against the C runtime library. You'd think we'd have that finished by now, but no. 5) wintab, i.e. the library and service that lets Tablet PC apps run. John Klehm got started on that this summer, but wasn't able to get the event sink demo app running. All of the above would probably be fun, and all have the property that you could make useful progress in a month or two. I'm sure there are lots of other ideas... - Dan

Is it possible to add a function to libwine that contains this code and then forward both these API to that one? Then you don't have the code duplication. - Reece

That way we can legally use > those DLLs without a Windows licence. Ah, but look at the EULA. For instance, the Visual C++ 6 EULA http://kegel.com/wine/isv/visual-studio-6-EULA.html says in section 4.1 that any app that redistributes its redistributables has to add "significant and primary functionality". Thus a do-nothing app would probably not satisfy the EULA, but a fun game might. So, rather than creating such an app yourself, it might be better to go look for existing freely distributed apps (preferably from Microsoft!) which already do this. For instance, Word Viewer 97 from MS has a very liberal EULA that allows free redistribution, and providesl DOCOBJ.DLL (required for Dragon Naturally Speaking) and tahoma font. There are probably several similar apps from Microsoft with unlimited redistribution that happen to bundle mfc40 and mfc42. No reason we couldn't put those apps up on winehq.org, and add an easy way in Wine to download the Popular Application Pack or something like that. - Dan

winhelp, Vector NTI, molecular biologists
by Misha Koshelev 03 Sep '07

Hi everybody, So as you all know I've been working on various bug fixes throughout wine, with my most significant contributions to date being MSI OLE automation support and implementation of http protocol support in urlmon. This involvement was driven by my initial experiences of getting a key program used by molecular biologists, Invitrogen's Vector NTI, to install on wine with a fairly convoluted shell script and submitting my first patch to fix a crash with this program; Dan Kegel helped me iron out this first patch a lot and furthermore his comments about how it'd be nice if such a complicated shell script was not necessary with wine got me started with my other patches and the rest, as they say, is history. So why, you may ask, am I sending all this in an email to wine-devel? The short answer is that this is a shameless email to see if I might motivate someone to work on our winhelp implementation a bit, as it is currently completely useless with Vector NTI. This seems like a fairly significant task, and my obligations at school/work have recently kicked up quite a bit, making it unlikely I will be able to take it on anytime soon. However, I hope to motivate someone with these reasons: (i) I feel like I've certainly been doing (and will continue to do) my part in helping out wine, and if this in any case motivates someone looking for a development direction I would certainly not object; and (ii) My ultimate vision/goal has been to have Vector NTI run so well that I could approach Invitrogen and see if they might at the very least say something to that effect on their Web site ("add wine + linux as a supported platform"), if not package Vector NTI a la Google Picassa, which would be great publicity for wine. Also, as you can see from the comments on my ubuntuforums howto http://ubuntuforums.org/showthread.php?t=347095 for a lot of molecular biologists, Vector NTI is the only reason they have to dual-boot/use VMWare at all (full-disclaimer: this is not 100% true for myself). So you could help perhaps a fairly small but non-insignificant group of people by doing some work on winhelp. Although Vector NTI is a rather large set of programs, currently I believe the only things keeping it from installing/working to a "gold" level according to winehq definitions are (i) winhelp and (ii) either MFC42 implementation (required for WSH to install properly; I suppose only a few functions prob are really required, but I'm not sure how good an idea having a very small stub MFC42 would be) or JScript support in wine. Either item in (ii) seems like a very significant undertaking, but (i) seems doable and prob. necessary for a lot of apps. So anyhow just my attempt to influence someone to start working on winhelp. Sorry for cluttering your inboxes. Misha

Re: dsound: Runtime link to advapi32 RegDeleteTree

Correct me if I am wrong on this, but I have a few questions. And I apologise if I ask some stupid questions, as I don't understand how the Wine loader works.

It's either > this or adding RegDeleteTree to libwine, unless someone has a third option. If the intent is to get this working on native, adding RegDeleteTree to libwine will not help. Unless you mean running Wine in Windows XP or earlier compatibility mode? If so, I was under the assumption that all the API were available to Wine, it was just the reported OS version that differed. I say this, because none of the Windows headers vary on OS version like the Windows SDK does. Even so, since the RegDeleteTree API are queried for by GetProcAddress, this means that they will not be found on WinXP and earlier, so DllUnregisterServer will fail on those platforms, leaving behind the dsound GUIDs on those platforms. This is bad practice, but I don't see how else this will work (assuming that these are run on native). > +static typeof(RegDeleteTreeW) * pRegDeleteTreeW; Is it common practice in Wine to use typeof? I was under the assumption that this was limited to the gcc C++ compiler. Even if it is available in the C compiler, it is not portable to compilers that don't support that, such as pre-typeof gcc compilers. - Reece

Hmm. Cider and the LGPL
by Dan Kegel 03 Sep '07

03 Sep '07

http://www.linux-community.de/story?storyid=23294 and http://www.macnews.de/news/102145.html mention that some users are using Cider from one game to run a second game on the Mac. The game vendors are upset, and are saying they'll do something to make that harder. There is some question about whether Cider includes LGPL components of Wine, and whether there are any violations lurking there. I imagine our friends at Cedega would instinctively avoid such infringement, but accidents might happen. It'll be interesting to see if anybody finds a real problem. - Dan -- Wine for Windows ISVs: http://kegel.com/wine/isv

Hi Just thought I'd share this with you all. http://www.theinquirer.net/default.aspx?article=42069 For those of you that haven't heard I know FarCry works with wine I'm not sure about the other 2 but it could be worth making them work if they don't as a PR exercise especally if they work under Ceider Any hoo I should be off to bed now Mike
