Not according to the David Elliot and I agree.

As said above the only thing it would enforce would be file seperation so you more easily could integrate the part from Transgaming in your CrossOver product. Of course distributing it after that would violate Transgamings copyright, so you really need their permission after all. The point is LGPL wouldn't help you here. > However, I can imagine alternate scenarios where we could > have all of > our hard work > used against us by others who are more ruthless than Gav, and so the > LGPL would at least offer us some protection from that threat.

To be honest and actually say something in support of LGPL: This wouldn't be required even with a strict LGPL interpretation. You would have to provide object files for relinking but that would not be much worse than providing the binary.

Wine and Baldur's Gate
by Ian D . Stewart Dec. 17, 2001

Dec. 17, 2001

Well, Now that I've made it through the actual install, I figured I'ld take Baldur's Gate for a spin. The main screeen, where you select to play the game, change the configuration, etc, comes up fine. There's a slight pause after clicking 'Play' while BGMain.exe starts and X is set yo 640x480 (I'm guessing this has something to do with DETACH_PROCESS?), but that's no biggy. The opening credits and movie play just fine. I'm able to create the main character without any noticeable problems. The first 'problem' I ran into was at the opening of the 'Prologue' chapter. Under windows, a narrator's voice reads the opening text as it scrolls across the screen. Under wine, the text is scrolling, but sans naration. A bit annoying, but no biggy. The real fun starts when the game actually begins. First off, the sound, when there is any, cuts out quite a bit, with no apparent rhyme nor reason. Secondly, the left and bottom panels are covered by the main section. You have to click on the various buttons to make them display. The third 'error' appears to be related to X's virtual desktop. Moving the cursor to the left or bottom side of the screen moves the 'viewport' away from the window, instead of scrolling the view in the Baldur's Gate window. After shutting down Baldur's Gate, I noticed a whole slew of error messages in the xterm window I launched it from. Here are a few examples: fixme:module:CreateProcessA (BGMain.exe,...): DETACHED_PROCESS ignored fixme:dsound:IDirectSoundImpl_SetCooperativeLevel (0x403f8034,00020021,3):stub fixme:dsound:IDirectSoundBufferImpl_QueryInterface Unknown GUID {31efac30-515c-11d0-a9aa-00aa0061be93} fixme:ddraw:Main_DirectDraw_CreateSurface App didn't request a valid surface type - assuming offscreenplain err:ddraw:Main_DirectDrawSurface_Lock Negative values in LPRECT !!! fixme:ddraw:DIB_DirectDrawSurface_Blt Unsupported flags: DDBLT_DDFX Any help in getting any of these issues resolved would be greatly appreciated!

Big Bummer for running Shrinkered files!
by Robert Baruch Dec. 17, 2001

Dec. 17, 2001

The plot sickens... Here's the background info. I have a file, power-structure-demo.exe which can be obtained from www.write-brain.com. Uwe has another file, tar2001.exe. Both have been compressed by the commercial Shrinker utility. When these exe's are run under Wine, Wine will spin. A look at the +all debug messages shows that the app tries to write into its own code area in order to purposely throw an exception. Kind of like this: void my_function() { try { *(char *)&my_function = *(char *)&my_function; } catch (access violation) { } } Shrinker was written using Visual C++, since this article at MSJ (http://www.microsoft.com/msj/defaultframe.asp?page=/msj/0197/exception/exce…) describes the code's exception handler perfectly. The Visual C++ exception handler, which gets control of the app from ntdll.dll, first calls a filter function corresponding to the catch clause to see if the handler associated with the catch will handle the exception. If so, it passes control to that handler. Otherwise it moves to the next catch clause. Here's the weird thing. The filter function looks at the code which called the exception handler, which is in ntdll.dll. Under Windows, this code is FFD1 (call ecx). The filter function compares that code to the call ecx instruction. At first the only difference between Wine and Windows is this comparison. A register gets decremented if the comparison fails. However, then the function calls ReadProcessMemory with a handle of -1 (what does that do?) to read 8 bytes, and compares some of the data returned to FFD1, and to 648B25 (which is the beginning of the next instruction after call ecx, mov esp,fs:[00000000]). Things rapidly deviate from there, resulting in Wine spinning and Windows continuing execution. Given that the application appears to look into ntdll.dll's code to compare it against essentially a magic number, is there any hope of getting Shrinkered exe's to run under Wine? --Rob

This has nothing to do with license, Transgaming or anything. All that is needed is a developer writing code. If there is none, nothing is written. Before Lionel Ulmer, there was no big DirectX game that could be played under Wine I think. Now Lionel is not contributing anymore - did he say to you privately that this was because of Transgaming ? There are many other top developers who have faded away like he did since I began on Wine, so it could be for many other reasons. Now, game users can as well subscribe to Transgaming as far as I am concerned. The vast majority of them seem to need professionnal - paid - support anyway. <snip> >> You want to use the Gpl as a tool, but I don't see a lot of respect >> for the philosophy that is behind it. > >I must say I'm quite offended by your comments.

If I am here, that's because I think that having Win32 Api outside of Windows is important. User rights have never got in the figure, since it was always acknowledged that people could take the stuff and turn it proprietary. Now that someone seems to succeed, you want to change the rules. Transgaming is playing by the existing rules, the rules you have enforced for a long time. If they are hurting you, that's surprising. They are not hurting me, since I have accepted your rules. What you are planning will hurt Transgaming business plan, by spreading Fear, Uncertainty and Doubt in their business discussions with potential customers. Business plan that they did and implemented in good faith, perfectly conforming to your rules and expecting their stability. I'd have no objection to Gpl *if* people having invested money in Wine success accept the move without problem. I think you should feel more responsibility towards people investing in Wine, not only responsibility towards the project - in other words you, because you are the Wine project. <snip> >I'm not planning to send anybody to jail, and I find that suggestion >insulting.

Here is a good counter-example. Sun Microsystems developed a toolkit that would convert linux network drivers source to function with Solaris (their proprietary OS). It was just a toolkit. They weren't distributing driver binaries. AFAIK, this use is perfectly legal to do with the GPL. What happens? The GPL GNUts get all bent out of shape because it allowed use of their drivers under a proprietary OS, so Sun yanked it, even though they were not in violation. As a *USER*, this is a negative impact placed on me by the linux developers to exercise my rights, since it impedes my ability to USE GPLed software. > > The usual argument about Gpl, that courts would not accept the > > action because there is no material interest (money) for Linus > > Torvalds, for example, in Linux, is akin to mine, but my point of > > view is not legalistic. > That's a load of bull, of course.

Wether this is good or not for users it's irrelevant. You probably meant something other than what you wrote here. Existence for the sake of existence is useless. I would presume the point of wine is to provide a WINXX environment on top of x86 platforms. If M$ was sued into oblivion tomorrow, and Wine was a *perfect* 95/98/ME/XP emulator, there would be no need for future development (other than to port to new platforms). The point is that the end goal is to attempt to be the perfect emulator for the USER - not to keep wine going indefinitely. > Some may say yes, others (e.g. Microsoft) may say no.

It is not an overstatement to say that *GPL is a net discouragement to commercial development - the GPL and FSF are openly hostile to proprietary software - PERIOD. Anyone who claims otherwise must also believe that M$ is "encouraging innovation". I can also add a few more cons: -- FSF discourages use of LGPL -- Discourages commercial companies for its use/development. -- Adds more confusion to the mix - LGPL ramifications is less understood than the GPL. > BSD > (just negate the above) > > And now for the second part: Wine should have a life of its own.

GPL is a *part* of open software - it is not the definition of open software. I don't believe anyone here is advocating making wine non-open. The problem wine has is that it is not a small endeavor like most GPLed software. If you look at the larger projects (gcc, gdb, openoffice, apache, x11, mozilla..), you will find the ones that are most successful long term are the ones with active corporate involvement. With this in mind, I think wine is better served by having its use proliferate and being more complete (even at the expense of having propriatary extensions), than having something that is incomplete but "free". As a side question, what IS the difference between what's available on winehq vs codeweavers? -- Roger Fujii <rmf(a)lookhere.com> Underemployed, and trying to keep it that way....
