Copy Protection & WINE
by Jonathan Wilson 02 Jun '05

02 Jun '05

From what I understand, there are 3 ways to do copy protection in WINE (at least for copy protection that needs a kernel driver to work): 1.Implement a WINE implementation of that kernel driver (in the same way various stock windows kernel drivers have been implemented). Problem with this is that there is a big DMCA risk (which is why AFAIK its been rejected) 2.Implement a fake NTOSKRNL that has just the entrypoints for accessing and loading copy protection drivers (the set of kernel calls needed by the copy protection drivers is only a very small subset of the total set of kernel calls and AFAIK none of them are hardware related) or 3.Implement a proper kernel driver loader (i.e. one that would sit in the windows kernel and do the same sort of thing as that ndiswrapper and that ntfs.sys loader do) What is the current state of copy protection work for WINE? Which of these 3 options do the developers intend to follow? (I remember someone posted some actual code for option 2 but I dont remember if anything happened with it)

Re: fixes for -Wmissing-declarations and -Wwrite-strings warnings

looking at the patch, I saw something in the code that made me sick: char *audioAutoDetect(void) { [snip] char *driversFound[10]; [snip] return driversFound[0]; [snip] } can someone fix that broken code ? that would be another nice janitorial task to check whether this kind of error exists somewhere else (I'd bet it does) A+

Sure, your objective was to fix all strict compiler warnings which that patch probably did successfully, but why not go that extra mile... Andreas Mohr

Winelib MFC app crashes after printing
by Eugene Aksenov 02 Jun '05

02 Jun '05

Hello, I have a small MFC app ported to winelib which uses MFC compiled with winelib. Really, it is just an App-Wizard generated application. I always have a crash of the application after printing. The page is printed ok but after that the app crashes. I use LPD for printing and my command line from wine is 'lpr -P<myprinter>'. I also try to print without MFC support i.e creating the printer DC by hand etc - the crash is the same, it follows EndDoc() call. There is no crash like this at the same linux configuration using in a 'pure' Win32 simple application without MFC though the code for printing is the same. When i print to file, all is ok. So , my current workaround is printing to a temp file and then send the file to lpr. I use RH9.0, wine20050419. My [spooler] section in config is the default from the wine installation. Did anybody meet a problem like that ? Is it MFC that has some impact here ? Thanks a lot for any hints.

Weirdness in the makefile
by Scott Ritchie 02 Jun '05

02 Jun '05

Can someone explain the significance of these targets in the makefile: manpages: $(MKINSTALLDIRS) $(TOPOBJDIR)/documentation/man3w cd dlls && $(MAKE) man htmlpages: $(MKINSTALLDIRS) $(TOPOBJDIR)/documentation/html cd dlls && $(MAKE) doc-html sgmlpages: $(MKINSTALLDIRS) $(TOPOBJDIR)/documentation/api-guide cd dlls && $(MAKE) doc-sgml Do they do anything? Those don't seem to be valid directories anymore. Thanks, Scott Ritchie

Darn, can't they use a magic keyword or similar mechanisms to mark elements scheduled for clean removal right before the next major version?? (and not out of sudden within almost the same version number) OK, some changes in that area might be non-trivial, so they do it when they feel like doing it, but I really doubt that this is the majority. But OTOH projects have to do binary incompatible changes a bit before the release of the next major version, otherwise there won't be any testing. And perhaps glibc is in such a version change phase right now... Andreas Mohr

Hello! I'm in trouble trying to estimate effort needed to implement marshalling interoperable with MS. Is it a right task for 2-2.5 months of Google's "Summer of Code"? Best regards, Ivan Pechorin.
