winsock2.h
by lawson_whitney＠juno.com 20 Nov '01

20 Nov '01

Good day! To try debugging techniques for winelib apps, I had in mind to make a winelib app with an intentional segment fault, and found that _my_ winelib app will no longer compile. (gcc-2.95.3, glibc-2.2.3, current wine CVS). Please, it needs unistd.h so it can comfortably log to syslog. running winemaker on it again didn't help. checking for wrc... /usr/local/bin/wrc updating cache ./config.cache creating ./config.status creating Make.rules creating Makefile creating launcher Configure finished. Do 'make' to build the project. [whit@giftie wlp]$ make gcc -c -g -O2 -fPIC -D_REENTRANT -DWINELIB -I. -I/usr/local/include/wine -o t oj2.o toj2.c In file included from /usr/local/include/wine/winsock2.h:30, from /usr/local/include/wine/windows.h:39, from toj2.h:29, from toj2.c:19: /usr/local/include/wine/winsock.h:886: conflicting types for `gethostname' /usr/include/unistd.h:734: previous declaration of `gethostname' make: *** [toj2.o] Error 1 [whit@giftie wlp]$ I would be glad of a bit of advice thanks, Lawson Constants aren't, and variables won't.

Civilization2 segment register troubles
by Jukka Heinonen 20 Nov '01

20 Nov '01

Hi. I noticed that Civilization 2 has several problems under Wine. First, the game wants to access memory using segment register value zero, which causes protection exception since that is not allowed in protected mode. Second problem is that the game uses segment register value 0xf8, which Wine does not like. If I drop null-pointer protection [call to DOSMEM_Init(TRUE)], emulate cmp and mov commands so that they work even if using segment register value zero [added stuff to memory/instr.c] and make Wine accept segment register value 0xf8 [by hacking INSTR_ReplaceSelector], Civilization 2 starts to work without any problems. There are several possible reasons why the above changes make the game work: Wine corrupts segment registers somewhere, Civilization 2 wants to use privileged commands and Windows emulates them or the game runs in VM86 mode under Windows. So, I would like to get some ideas what should be done with Wine in order to get the game working. Oh, the above modifications fix protection faults that happen when the game tries to access the following addresses: 0x22, 0xc8, 0xf6, 0xf07c and 0xf0aa. P.S. Civilization 2 seems to work almost perfectly but it is painfully slow. I am pretty certain that I know the reason for this, but I would like to get the game working under official Wine before trying to make it run faster. -- Jukka Heinonen <http://www.iki.fi/jhei/>

Re: Patches for FreeBSD 5.x compilation

The Wine headers that define struct thread are only used inside Wine; the FreeBSD headers are used by applications, no matter how much you argue they are internal headers.

I was simply expressing the opinion that changing this would make FreeBSD better. I'm certainly not demanding that the FreeBSD guys fix it, if they feel exporting struct thread is a good idea it's their choice. -- Alexandre Julliard julliard(a)winehq.com

Yes of course it can, but the fact that this isn't explicitly forbidden by some standard doesn't mean it's good practice or that it doesn't pollute the namespace. sys/user.h is also legally allowed to do "#define if else"; that doesn't make it a good idea. > If an application includes > <sys/user.h>, then the application should be prepared to > deal with conflicts. Great, then you need to fix all applications every time someone feels like exporting a new symbol from user.h. Of course user.h is a pretty obscure header so it's no big deal, but it would be easier to avoid exporting stuff under such common names as "struct thread". -- Alexandre Julliard julliard(a)winehq.com

interesting comment about WINE from MS
by Igor 20 Nov '01

20 Nov '01

As far as WINE and Mono are concerned, I'm just not sure whether these organizations will end up being able to produce satisfactory products. The real problem is this: it is not good enough for WINE to run some Windows apps. If the general public is going to consume it, it must run all Windows apps. Windows 2000/XP has a significant level of POSIX compliancy, but many developers just don?t write their apps with these standards in mind. You'll find pieces of code everywhere in third party apps which run statements like if (WINVER==4.0 && GrokTheBIOSForSomeACPIGoo()), which have not been tested to see whether they will run on non-Windows/x86 platforms. In fact, Microsoft has had to put in significant time and effort to insure that older Win32 applications originally written to run in Win95 will run in NT." original article is here http://www.osnews.com/story.php?news_id=314

Implementation of TB_REPLACEBITMAP

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all. I'm trying to provide an implementation of TB_REPLACEBITMAP Included is the patch I've done to record the bitmaps which are provided to the toolbar and to replace them when the message arrives.

audio.c fault reproduction
by Simon Britnell 20 Nov '01

20 Nov '01

I downloaded and ran the QuickTime installer and the Pajama Sam demo last PM. I have reproduced the problem with Pajama Sam (it seems that ends of samples are either not playing or being overwritten), but I can't get QuickTimePlayer.exe to do anything at all. I'll investigate the Pajama Sam problems over the remainder of the week. __________________________________________________ Do You Yahoo!? Yahoo!

I'm here. :-) Well, I wouldn't really go quite that far. The API definitions in themselves can't be copyrighted, true. But a specific way of expressing them is, so compiling any Microsoft file will generate create a derived work copyrighted by Microsoft as the main rule. However it is not quite that easy, since only the specific expression is protected, the compilation result is only a derived work if it still contains any protected expression. In light of this you could argue that since, I presume, MIDL removes whitespace and commments which is IIRC the only really expression, since the rest the API defintions are just facts, that the MIDL compiled files just contains facts not any part of the protected expression. However that is a little thin line to walk, since there is quite of lack of real cases in the area, so I would recommend that we do as Alexandre suggest. Beside having the real .idl files in the Wine tree might be useful for other things as well.

I'd prefer not. If we want to use .idl files we'll have to come up with our own compiler, and then we can put the .idl source in the tree and compile it at build time. > And how about source IDL files?

No, anything generated from a Windows file is copyrighted by Microsoft, so we cannot distribute it.

I'd prefer having a separate process, at least in the first stage. -- Alexandre Julliard julliard(a)winehq.com
