current cvs doesn't compile with freetype-2.0.3
by Ben Stanley 01 Jan '02

01 Jan '02

Hi, I tried compiling current cvs wine on RH 7.2, and it fails... gcc -c -I. -I. -I../../include -I../../include -I/usr/include/freetype2 -g -O2 -Wall -mpreferred-stack-boundary=2 -fPIC -D__WINE__ -D_REENTRANT -I/usr/X11R6/include -o freetype.o freetype.c freetype.c:43:31: freetype/ftnames.h: No such file or directory make[2]: *** [freetype.o] Error 1 make[2]: Leaving directory `/share/building/wine/wine/dlls/gdi' It seems that the autoconf test for freetype/ftnames.h doesn't work properly. The file is not present in the RH package, and is not included in the freetype-2.0.3 tarball either. BTW, I'm not on the list atm. Ben.

mvcrt.ungetc and stdio buffering
by Waldek Hebisch 31 Dec '01

31 Dec '01

Recently I tried to run g77 compiled Fortran program under Wine. It seems that to do any input g77 uses `ungetc'. Currently, Wine msvcrt has unbufferd stdio. I would like to add buffering and implement `ungetc'. Are there any traps (thread safety ??) or will strightforward implementation work ? -- Waldek Hebisch hebisch(a)math.uni.wroc.pl or hebisch(a)hera.math.uni.wroc.pl

Does I thought to quibble with that, but it is a pretty fair analogy after all. Wine (including wineserver and wine builtin dlls) is a *NIX application, but it does provide "OS" services. It sort of needs an address space or two to kick around if it is going to be able to load native dlls that are not relocatable, FI. > that mean that this is the only way to start a wine application?

Is it possible to do it in an easier way? There isn't all that much to the wine executable these days. Most of Wine is in the builtin dlls and the wineserver. Have a look at <wine>/miscemu/main.c. If you think you can get that to run inside your plugin, maybe you can. Codeweavers did a crossover plugin whosis for linux browsers, I think, that would have had to address the problems. Lawson

Re: We *really* need a development model change !
by Andriy Palamarchuk 29 Dec '01

Simplicity is one of the goals of the testing framework, but besides being simple the framework should be powerful enough for such big project. I'm looking for existing library which would suit our needs. Unit test framework "Check" looks promising. It provides many features which I'd love to use for our tests, including: - protection of the test address space - tests crashed do not put down the whole test suite and are reported. At the same time you can request to run tests in the same address space what is good for debugging. - grouping tests in suites, tree-like grouping of the test suites. You can choose to run only subset of the tests - having "set up" and "tear down" sections which can be used to set up tests and free resourses after. - a few forms of output - from silent to detailed Individual test looks like (section from manual): START_TEST(test_create) { fail_unless (money_amount(five_dollars) == 5, "Amount not set correctly on creation"); fail_unless (strcmp(money_currency(five_dollars),"USD") == 0, "Currency not set correctly on creation"); } END_TEST They also give information how to configure the tests with autoconf. The issues which need to be resolved: 1) License - GPL. Is it Ok to have the test suite under GPL? 2) Environment - POSIX. The library uses POSIX calls to manage processes, in particular functions fork, _exit, write, read, close, getppid, getpid, pipe. Calls "fork" , "_exit" and "getppid" are used only when test runs in FORK mode. We don't need to have address space protection under Windows - tests there should not crash. The rest of functions are used for communication between the test launcher and tests and can be implemented with using corresponding Win32 calls. After implementing these changes the framework can be used in pure Win32 environment, without Cygwin. Let me know if you are interested. I'll start to work on the port. Meantime we can start to use the framework under Wine and on Windows with Cygwin. More information about Check you can find here: http://check.sourceforge.net/ - home page http://sourceforge.net/project/showfiles.php?group_id=28255 - tutorial Thanks, Andriy Palamarchuk __________________________________________________ Do You Yahoo!?

Getting "Practice Exam" software working
by Dax Kelson 29 Dec '01

29 Dec '01

We have a training room full of students who are taking a cisco networking design class. The class is basically all lecture so they don't normally use a computer, but tomorrow the students need to take a practice exam. The student workstations are running Red Hat Linux 7.2. Their student books come with a CDROM with a practice exam program that is, of course, a windows app. I've tried with the Wine that shipped with RH7.2, todays CVS snapshot, and Codeweaver's preview 5 all with the same results. It *almost* works. I would rather get it working so we don't have install windows just for them to run this one app. The problem starts up ok as seen in the screenshots 1 through 3 below. http://www.gurulabs.com/files/snapshot1.png http://www.gurulabs.com/files/snapshot2.png http://www.gurulabs.com/files/snapshot3.png http://www.gurulabs.com/files/snapshot4.png <- Problem here The problem is the sample questions and answers don't show up. http://www.gurulabs.com/files/snapshot5.png The "exhibits" seem to work fine. I'm using 100% builtin. There are no warnings or outputs that are displayed when exam question window starts. Any help would be greatly appreciated. Please save me from having to install windows on 13 computers. :) Dax Kelson

Using windows dlls in unix shared libraries
by Robert Jonsson 28 Dec '01

28 Dec '01

Hi all, I just subscribed to this list, I hope my questions aren't evidently answered elsewhere, I tried to do some homework browsing the docs and parts of the mailing list, but then again I'm no pro so I might have missed it. The background story: There is a plugin system for professional audio applications in Windows called VST. I suppose it does pretty much the same job as a multimedia codec. With the exception that they have internally generated GUIs! Perhaps a winamp plugin would be the closest match. There is a similar format in Linux called LADSPA (www.ladspa.org). Basically what I seek to do is try and wrap a VST plugin in a LADSPA plugin. The question: I don't know that much about Wine internals, but all the example applications I've looked at use the wine executable as boot loader. Does that mean that this is the only way to start a wine application? The way I'd like to use it is like this: Linuxhost (dlopen ladspaplug) - LADSPAplugin (LoadLibrary vstplugin) - VSTplugin A possible solution would be to startup the VSTplugin in another application and do IPC between the LADSPAplugin and the VSTplugin-proxyhost. Like this: Linuxhost (dlopen ladspaplug) - LADSPAplugin <----ipc----> winebased_VSThost (LoadLibrary vstplugin) - VSTplugin This does however seem akward... Is it possible to do it in an easier way? Btw, I know about the avifile project, don't know the history but it is based on wine right? However, to my knowledge avifile supports only a very limited amount of API calls, ie no graphics/window calls (perhaps except some trivial ones). Which would probably make it pretty hard to implement the above...

We *really* need a development model change !
by Andreas Mohr 26 Dec '01

26 Dec '01

Hi all, due to the number of regressions I found few days ago, it occurred to me that we really need an API test suite now. Thus I went ahead and implemented a test functionality for LoadModule16(). The result: 7 of the 21 tests that I implemented were FAILING !! That's ONE THIRD. And that for such a highly basic function as LoadModule16(). That's quite incredible. I guess we really should change our development model from trying tons of programs to *systematically* testing functions and Windows mechanisms now. If we can show everyone where stuff is failing, it might be a lot easier to attract new people. I attached a preview of the posting I intend to post on *tons* of Windows devel newsgroups ("Call For Volunteers"). That way we might actually get hold of hundreds of Windows developers helping us implement a complete test suite (complete tests of up to 12000 Windows functions). Not to mention the additional PR we might get out of this... If this works, then we'd need someone in charge of managing the assignment of specific windows functions to specific programmers. I won't do that (very limited time). Anyone from Codeweavers up to the task ? Or maybe someone non-developer and rather foreign to the Wine devel could do that task ? About the program: My goal was to get a program with very easy parsing interface: fields separated by colons, nothing fancy and difficult to implement, ... A .exe can be found at: http://home.nexgo.de/andi.mohr/download/wt_ldr16.exe Please comment on both my intended posting and the way I programmed the first version of the test suite (I'm not extremely happy with the current program; if you have any improvements, then get them here ASAP !). As 12000 Windows functions is an enormous number, I think we should really start doing this NOW instead of years later once Wine really needs this. Wine does not extremely need this yet, but we're getting pretty damn close to that already. Thanks ! -- Andreas Mohr Stauferstr. 6, D-71272 Renningen, Germany

I *completely* support this idea. Benefits of such test suite are enormous. Existing developers can contribute a lot by adding test snippets for the functions they create. Now they create such snippets anyway and throw them away. > I attached a preview of the posting I intend to post on *tons* of Windows > devel newsgroups ("Call For Volunteers").

Lets ask for help only after the suite structure is more/less defined and we'll be able to give people something to work on. Comments: - Don't want to reinvent the weel. Is there any existing test suite framework we can use? Sorry, I can't suggest any for C but I'm very impressed with JUnit in Java. It is even Ok if the framework is GPLed or LGPLed - I don't think any company will make buziness based on the test suite. - I /personally/ prefer CL interface only for such suite - it would be better if the suite print summary information and information about failed tests only - make the test suite more "visible" for existing developers. Ask them to run the test suite before submitting a patch? - I think the suite test will consist from a few separate applications because different tests may have different requirements to GUI configuration, processes, etc. We need a way to run all the applications in one batch. - define variable which indicates whether the suite runs under Wine. Such indicator can be used for Wine "white-box" testing. - it would be greate to have functionality to support output comparison? For some functionality it is easier to write tests to compare output instead of doing explicit checks (e.g. tests, involving a few processes). The output can be redirected to file and files compared. If we use files we need to store files for Wine and a few versions of Windows :-( - the suite applications size will be pretty big. Is it better to move it to separate CVS tree? - what about running the suite weekly (or daily) automatically and publishing the results to wine-devel? - most developers on this list have access to one version of Windows. Is it difficult to create "testing farm" with remote access to a few versions of windows? This would help developers to test their code on a few platforms. Existing environments in the companies, involved in the project can be used. - I remember long time ago there was a post on wine-devel about using Perl or Perl-like language for unit testing. What is current status of that project? Thanks, Andriy Palamarchuk __________________________________________________ Do You Yahoo!?

Cooperation between Odin & Wine
by Sander van Leeuwen 26 Dec '01

26 Dec '01

Hi, As some of you might remember I'm the lead developer of the Odin project. (project for OS/2 with the same goals as Wine). Odin is partly based on Wine code. The core dlls (gdi32, user32, kernel32) + some special dlls (winmm, directx, winsock) use some Wine code, but is basically incompatible with Wine for obvious reasons. Most of the remaining dlls are based entirely on Wine code. The last few years there has been little cooperation between both projects for several reasons. One of them is that we have far fewer active developers and cooperation sometimes proved to be difficult. Some source files of the two project had grown apart since changes were never merged back into Wine. Now, I'm trying to change this situation, but am wondering how to proceed. I can post bug fixes to this list, but it will be difficult for me to actually test these changes in Wine itself. (too time consuming) Posting diff files is not always possible due to the major differences between source files. Merging changes from Wine into our source tree is no problem. We can do that ourselves. However, it would be nice if compiler incompatibilites (we use IBM VisualAge C++, not GCC) could be resolved. There aren't many, but the IBM compiler is not always as flexible as GCC and of course doesn't understand any GCC extensions. It would be a big help if incompatible code could be changed. Switching compilers is not an option for us. I can post a (small) list of changes we had to make. The license of our project is not compatible with Wine, but the dlls that are largely based on Wine (such as comctl32, shell32, ole) are an exception to the project license. The sources of those dlls are released under the Wine license. In case there is ever interest in the other sources, then you can just ask me. I'd be happy to 'donate' them to Wine. For more information about Odin you can visit http://odin.netlabs.org (some information is outdated though). There you can find out where to download the sources (cvs). The next post from me will contains some patches for bugs in Wine that I've recently found. Sander

Re: Wine Tasklist (UNC)
by Mike McCormack 26 Dec '01

26 Dec '01

Hi Francois, I think the best way to handle UNC pathes is to do it properly; Wine should talk SMB/NBT directly to other machines on the network, not through Linux's VFS layer. This approach would give high level of flexability to Wine. We could: * support NetDDE and DCOM with a common code base * use Windows file permissions and security properly * support unicode share names properly * support named pipes, etc across the network * eliminate SMB<->VFS<->SMB problems eg. parsing /etc/fstab There's three options: 1) write our own SMB code (wineserver talks NetBIOS/SMB) i have a short snippet of code to resolve NetBIOS names in CreateFile, but that is only the beginning of the effort. 2) link with a LGPL'ed CIFS implementation. http://www.ubiqx.org/libcifs/ (very incomplete, but maybe possible later, may still have threading issues) 3) get Samba to provide us with a Unix domain socket to talk with. (SambaTNG looks like the best bet there.) i have experimented with linking Wine to samba's libsmbclient and use it to open files. That works (i have a test patch), has threading and licensing issues (it's GPL). This would be alot of work, but i think it's the only way to do it properly.

Our tooltips has too many differences for diff to produce usable output, but the changes are similar to the other three. - COMCTL32: Tooltips: wrong COMCTL32_Free calls -> 4 calls with wrong pointer: COMCTL32_Free(&lpttsi); should be COMCTL32_Free(lpttsi); - user32: frame tracking * - Only draw changed track frame instead of clearing the old one and * drawing the new one (less flickering) * - Send WM_MOVING when moving a window * - Send WM_SIZING only when sizing a window * - Fixed handling of rectangles changed by WM_SIZING/MOVING -> Can't easily produce diff file. Too many changes. (check src\user32\wintrack.cpp in our CVS tree) - USER32: groupbox redrawing fixes -> I am not 100% sure the same happens in Wine, but it looks like that. When an application changes the font or the text of a groupbox (smaller font or fewer characters), then the old text has to be erase properly or else you'll still see part of it. If I remember correctly, that could be seen in Opera 5.12 (property dialogs) -> Again, too many changes to produce a diff file. (check src\user32\button.cpp, BUTTON_SetText & BUTTON_SetFont) - USER32: static control -> our version supports more styles (SS_CENTERIMAGE, SS_REALSIZEIMAGE) and features (SS_ENHMETAFILE) (src\user32\static.cpp) Sander

16 bit comm issue

Hi, There's a problem with the current 16bit comm architecture which i'm not sure how to solve correctly. If a 16bit Windows programs uses EnableCommNotification to receive WM_COMMNOTIFY messages then sits in a message loop waiting for them, it will never receive them because there is no chance for APC that sends the message (COMM16_ReadComplete) to run. I have a patch for this problem which puts an alertable wait in GetMessage(16), which i posted in October. What is the problem with this method, and is there a better solution to the problem?

When I started the Win98 setup.exe for fun, it choked on int 0x21 "list of lists" (DOS_LOLSeg not initialized). Trouble is that we initialize DOS variables in case of DOS programs *only*. This is rather fatal IMHO, especially in the case of List Of Lists, which is a pretty important structure with lots of information that some Win 3.x programs might rely on. Thus DOS stuff should be reorganized somehow. Any suggestions ? IMHO probably winedos should get loaded as soon as DOS3Call() gets called even once. -- Andreas Mohr Stauferstr. 6, D-71272 Renningen, Germany Tel. +49 7159 800604 http://home.nexgo.de/andi.mohr/

Terrible bug: WinExec16, DOS programs
by Andreas Mohr 24 Dec '01

Hi all, I just found out that WinExec16 doesn't even support starting DOS programs. Whereas LoadModule16 doesn't seem to support loading DOS programs (error 22, which is not documented for LoadModule16), WinExec16 definitely does launch command.com on Win98SE. Not so when using Wine. What to do about that ? More specifically, which functions to change how exactly to support this ? (the whole interoperation between WinExec, WinExec16, LoadModule*, LoadLibrary*,CreateProcess etc. is highly problematic). This thing makes me get slightly worried about our Win16/DOS compatibility as a whole... :-\ -- Andreas Mohr Stauferstr. 6, D-71272 Renningen, Germany Tel. +49 7159 800604 http://home.nexgo.de/andi.mohr/

The ODIN project's license is at http://odin.netlabs.org/License.phtml There was some talk of sharing code between Wine and Odin in 1999; see http://www.winehq.com/News/1999-50.html#0 We might want to update http://www.winehq.com/others.html to reflect the current status and license of the Odin project. I'm not quite sure whether the Odin license is compatible with the LGPL. It looks fairly GPL compatible, but I didn't look hard. - Dan

If ALL of wine were strictly LGPLed, basically, *all* propriatary extensions could no longer be included. Why? Because the output of winebuild will be LGPLed, thus no propriatary programs could use its output in creating a shared library. winebuild is like bison in this case, and the output of bison has a special exemption so that you can use it in something other than *GPLed programs. This inadvertant problem is precisely why *GPLed stuff has to be scrutinized carefully if you care about commercial relationships (most *GPL projects don't care) and is why commerical interests are wary of projects with a *GPL license. -r

I tried to do just that and got rejected ( error after submitting and didn't want to try 'again' until they contact me ) by the online payment system for some odd reason....I wonder how many others have experineced this ( I checked my input twice and had all *'s filled out )........granted it could be isolated in that I made some minor goof on form..-we'll see. just a fyi in case it wasnt' me.. lee -===
