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? Well, something has to be sure the wineserver is started. > The way I'd like to use it is like this: > Linuxhost (dlopen ladspaplug) - LADSPAplugin (LoadLibrary vstplugin) - > VSTplugin Can your ladspaplug not fork and exec wine to run your vst wrapper? > > 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? 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 !

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!?
