Installing office apps
by Anant Kabra Nov. 20, 2002

Nov. 20, 2002

Hi, I've got a windows free install of wine (Debian daily build package). I'm trying to install office apps (Office 2k - word, excel, ms project 2k), but for each I get the following behavior I go through the license key and customize installation sections fine, then it starts verifying install tasks, this gets about half way through then I get a dialog saying Internal error 2761: Contact product support for assistance. I click OK and the install terminates. Any ideas what's going on? Can I do anything else to provide more information? Thanks, -- Anant Kabra email: anant(a)yash.com phone: (210) 379-0338 (mobile)

_itoa

Nov. 20, 2002

Folks, msvcrt has this in its spec file: dlls/msvcrt/msvcrt.spec:@ forward -noimport _itoa ntdll._itoa Yet at link time, I get an undefined reference error: /home/dimi/dev/wine/wine/tools/winebuild/winebuild -fPIC -DSTRICT -o visual-mingw.exe.spec.c --exe visual-mingw.exe -m gui -r rsrc.res CList.o editor.o main.o process.o project.o winui.o -L/home/dimi/dev/wine/wine/dlls -ladvapi32 -lole32 -lcomdlg32 -lcomctl32 -lshell32 -luser32 -lgdi32 -lkernel32 -lmsvcrt gcc -D_WIN32_IE=0x0400 -c -o visual-mingw.exe.spec.o visual-mingw.exe.spec.c g++ -shared -Wl,-Bsymbolic visual-mingw.exe.spec.o CList.o editor.o main.o process.o project.o winui.o -o visual-mingw.exe.so -L/home/dimi/dev/wine/wine/library -lwine -lm project.o: In function `CProject::Open(char*, unsigned short)': project.o(.text+0x20e5): undefined reference to `_itoa' winui.o: In function `CStatusBar::WriteLong(long, int)': winui.o(.text+0x1d9a): undefined reference to `_itoa' winui.o: In function `CMessageBox::DisplayLong(long)': winui.o(.text+0x30a2): undefined reference to `_itoa' However, if I also link in ntdll, it works: /home/dimi/dev/wine/wine/tools/winebuild/winebuild -fPIC -DSTRICT -o visual-mingw.exe.spec.c --exe visual-mingw.exe -m gui -r rsrc.res CList.o editor.o main.o process.o project.o winui.o -L/home/dimi/dev/wine/wine/dlls -ladvapi32 -lole32 -lcomdlg32 -lcomctl32 -lshell32 -luser32 -lgdi32 -lkernel32 -lntdll -lmsvcrt gcc -D_WIN32_IE=0x0400 -c -o visual-mingw.exe.spec.o visual-mingw.exe.spec.c g++ -shared -Wl,-Bsymbolic visual-mingw.exe.spec.o CList.o editor.o main.o process.o project.o winui.o -o visual-mingw.exe.so -L/home/dimi/dev/wine/wine/library -lwine -lm [dimi(a)dimi src]$ Question is, is this correct?

Imporving support for graphics tablets in wine (wintab.dll)
by Robert North Nov. 20, 2002

Nov. 20, 2002

Modern graphics tablets also provide pressure and tilt information, essential for quality graphics editors such as Painter & Photoshop. Currently graphics tablets are treated as mice in wine, and so cannot provide this information to a Win16/32 app. To access pressure & tilt info in Windows, a programmer would use the wintab.dll. Has anyone attempted to build a wintab.dll for Wine? I'm interested in attempting an extremely limited implementation for Painter & Photoshop, but don't want to reinvent the wheel. Assuming nobody has done this what's the first step? Raise a bug, and accept it? Bye -Rob.

And it's most likely broken anyway. Now, why anyone do that? What's to gain? It doesn't help anyone, it just adds bloat and confusion to the tree. And waists valuable developer time.

Screenshots

Nov. 20, 2002

Hi, I'm happy to put together some screenshots on my RedHat 8 box at work (pretty much default install albiet with a slightly customised gnome2 layout). However it strikes me that having people just randomly send shots to Brian isn't the best way to go about it as nobody knows who has sent what. Have you actually got any yet Brian? If not, are there any apps you'd like to me make screenshots of? I currently have IE6 and WinZip installed, but can go install more if they are freely available on the net. thanks -mike -- Mike Hearn <m.hearn(a)signal.qinetiq.com> QinetiQ

Wine merge required: COM/OLE header changes
by Ove Kaaven Nov. 20, 2002

Nov. 20, 2002

These patches are against ReWind and requires some merging work in order to apply to Wine. Could someone (hm... Greg?) do that for me? The fundamental idea here is to make sure that no files except unknwn.h ever include wine/obj_base.h directly, because the IUnknown interface definition will soon move to unknwn.h, and the API function prototypes will move to objbase.h (which indirectly includes unknwn.h through objidl.h). While I was at it, I also made sure that a couple of common to-be-IDL-generated files aren't included directly, as the headers in question have wrapper headers that are supposed to contain related API function prototypes - these prototypes will also be moved later, so I thought I might as well ensure that the wrapper headers are used now. The attached comhdr1.diff contains header changes and #ifdef guards that force a compilation error if any of these "forbidden" headers are included directly. It seems to apply to Wine as-is. (And I think the #ifdef guards should be applied to Wine even if #ifdefs aren't popular around here, because it protects against introduction of new bad code in Wine while the conversion is in progress; and when a particular header has been successfully converted, its respective #ifdef guard will of course be removed again.) The attached comhdr2.diff seems to fix all the resulting compilation errors in ReWind, and is what needs "merging". Apply as much of it as you can and fix the compilation errors that remain in Wine. Thanks.

As I said, if you use getpwnam() you check for > HAVE_GETPWNAM; whether getpwuid() also exists or not is completely > irrelevant. Well, the problem is it is possible that you in order to fail gracefully needs to do different things depending on whether some other function exists or not. OK, the functions meantioned above are not likely to have side effect or something else that effect the other functions in any relevant way. But there might be function pairs, tripples etc that does. Sure you can say that since any function might fail any code should always be able to handle a missing function as well since it in some abstract meaning it sufficiently similar to a normal failure. But regardless, I think it is good to make it clear that he or she who wrote expects certain things to be true and things might not work if they are not true. I somebody hits the "assertion" they can audit the code and if it seems that it doesn't matter they can modify the "assertion" to whatever is proper in the light of the new different enviroment. If it does matter they will modify the code accordingly... Somehow this seems much better than just hoping that the orginal programmer handled all error cases correctly...

It was so obvious that I missed it. :-) Still I think the code should verify that any assumptions made str really true, if possible.

First of all copyright doesn't protection facts or ideas only a specific (and unique) expression of facts and ideas. This is normally called a work. Specifically it doesn't protect any underlying functionally inherent or derivable from the work. This is normally called the implementation of the functionallity. Even more specifically it doesn't protect the way interaction with any functionallity, that is possible to derived from the work, is done. This is normally called the interface to the functionallity. Header files for the most part defines interfaces; more specifically constant declarations (read: defines), function declarations, type declarations and. So all such things are free for taking. However netherless the less, the header file is not entirely free of possible protected expression. Specifically: 1. Formatting 2. Comments 3. Inline functions and complex macros I will address each them in turn. Formatting is not normally any problem since there are not that many way to format C declarations, none of which is likely to be unique to Microsoft, let alone expressive. Still I always format the new file in a way I personally like, just in case. Comments are are probably the largest proplem. They are not strictly part of the interface so if you are unsure you can just remove them. In most cases, in fact the intresting cases, however they contains facts about the interface. Note however I said _contains_ facts not are facts. Part of them might be protected expression so we have to be careful here. Again, note that in order to be protected an expression have to unique as well as expressive. Most short sentences are neither unique, nor are they expressive, they just explain the facts in some straight forward way. Still if the not formulated in a way I as well would use the express myself I rewrite them. As for longer sentences and specificially multi sentence paragraphs. I usually delete or reformulate and often shorten it using my own words. The comments are, as I said, not strictly needed in for the header file to work. Inline function and complex macros can be a little tricky. However they are usually rare so rewriting them in a way I would have written it is not that much work and functinallity in itself is I said explain above not protected by copyright.

What I meant is that the code shouldn't depend on the existance of the reentrant function since it is not that unlikely that some platforms might only have the non reentrent one only.

If are on a embedded platform it is not entirely unlikely that it is possible to configure and compile the C library to not handle reentrancy issues in order to optimize for space. In fact it might make sense be able compile Winelib as not supporting reentrency either. It is a post 1.0 issue IMHO, but we should have a policy planning for that possiblity nether the less. So strictly speaking, we should IMHO do #ifdef HAVE_GETPWUID_R /* Use getpwuid_r */ #elsif defined(HAVE_GETPWUID) # ifdef _REENTRANT /* Lock. Use getpwuid.

As Alexandre said, having a special define is completely unnessary. Just test for existance of whatever function when you call it.

Hi guys, Here's a small test program: #include <windows.h> #include <stdio.h> #include <stdlib.h> #include <assert.h> int main() { printf("sizeof(wchar_t)=%d\n", sizeof(wchar_t)); return 0; } And I want to compile this with our msvcrt headers. Look what happens: [dimi(a)dimi wine]$ gcc -nostdinc -fshort-wchar -I /home/dimi/dev/wine/wine.src/include/msvcrt -I /home/dimi/dev/wine/wine.src/include test.c In file included from /home/dimi/dev/wine/wine.src/include/windows.h:38, from test.c:1: /home/dimi/dev/wine/wine.src/include/winbase.h:23:20: stdarg.h: No such file or directory In file included from /home/dimi/dev/wine/wine.src/include/windows.h:38, from test.c:1: /home/dimi/dev/wine/wine.src/include/winbase.h:1257: parse error before "va_list" /home/dimi/dev/wine/wine.src/include/winbase.h:1258: parse error before "va_list" In file included from /home/dimi/dev/wine/wine.src/include/windows.h:40, from test.c:1: /home/dimi/dev/wine/wine.src/include/winuser.h:23:20: stdarg.h: No such file or directory In file included from /home/dimi/dev/wine/wine.src/include/windows.h:40, from test.c:1: /home/dimi/dev/wine/wine.src/include/winuser.h:4459: parse error before "va_list" /home/dimi/dev/wine/wine.src/include/winuser.h:4460: parse error before "va_list" In file included from test.c:2: /home/dimi/dev/wine/wine.src/include/msvcrt/stdio.h:13:20: stdarg.h: No such file or directory In file included from test.c:2: /home/dimi/dev/wine/wine.src/include/msvcrt/stdio.h:135: parse error before "va_list" /home/dimi/dev/wine/wine.src/include/msvcrt/stdio.h:175: parse error before "va_list" /home/dimi/dev/wine/wine.src/include/msvcrt/stdio.h:176: parse error before "va_list" /home/dimi/dev/wine/wine.src/include/msvcrt/stdio.h:177: parse error before "va_list" /home/dimi/dev/wine/wine.src/include/msvcrt/stdio.h:184: parse error before "va_list" /home/dimi/dev/wine/wine.src/include/msvcrt/stdio.h:211: parse error before "va_list" /home/dimi/dev/wine/wine.src/include/msvcrt/stdio.h:212: parse error before "va_list" /home/dimi/dev/wine/wine.src/include/msvcrt/stdio.h:213: parse error before "va_list" test.c:4:20: assert.h: No such file or directory test.c: In function `main': test.c:8: `wchar_t' undeclared (first use in this function) test.c:8: (Each undeclared identifier is reported only once test.c:8: for each function it appears in.) [dimi(a)dimi wine]$ First off, are we supposed to die on the va_list stuff? Second, why is wchar_t undeclared? -- Dimi. P.S. Please do not ask why so many includes, I know they are not needed, but it should work, right?

Question: domain name
by Martin Wilck Nov. 19, 2002

Nov. 19, 2002

Using a default domain name in Wine would be beneficial for certain Netapi functions. While it's no big deal to add a config option for that, there is the Windows registry value DefaultDomainName in HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Winlogon which could be used for exactly that purpose. Is it better to - use a Wine config key, - use the above MS key, - or use both, the Wine key overriding the MS one if set?

Must > I add more > checks for all the functions I use, or is it ok to assume that > getpwuid() presence implies getpwnam() presence? Good question. I'm don't think we have any policy concerning this. Perhaps we should have. One thing that you shouldn't assume is for example that if a function exists its reentrant variant exists as well. For example that fact getpwnam exists doesn't imply that getpwnam_r exists. And yes, you really should use the reentrent variant if present as well as having an alternative implementation if not. As to the implict existance question: I'm not sure. First of all, to answer the related question: Should you have a alternative implementation for defined(HAVE_GETPWUID) && !defined(HAVE_GETPWNAM)? IMHO the answer is no. It is not worth the effort to support hypotetical platforms unless we can verify the existance of one. To return to the original question: I suggest that we should detect the presence or absence of ALL function we use that is verified not to exist on some platform and have for example code like #if defined(HAVE_GETPWUID) || defined(HAVE_GETPWNAM) || defined(HAVE_GETPWENT) # if (defined(HAVE_GETPWUID) + defined(HAVE_GETPWNAM) + defined(HAVE_GETPWENT)) == 3 # define __HAVE_GETPW # else # error All or none of the functions getpwuid, getpwnam and getpwent are assumed to exist # endif #endif in order to formalize the assumptions and generate a common define to use in the code. Comments? Suggestions?
