Re: mvcrt.ungetc and stdio buffering
by Jon Griffiths 02 Jan '02

>Have a look at the following two messages from Marcus Meissner to >wine-devel and wine-patches: Hmm, those links dont work for me, however I remember: The header files for stdio have macro versions of putc/getc so your implementation must use the FILE structure fields in a binary compatable way (as they are currently; I implemented the code to pretend that the buffer is alway empty and needs to be reread/put on every operation). Provided you can make optimised VC++ compiled programs (i.e. those that use the macro version of get/putc) work, you dont have any extra threading issues that the code should handle already (but probably doesn't; large sections are not yet thread safed). The performance improvement would be significant also. You should make sure you test your changes thoroughly tho, as the file code is rather vital to avoiding needing native msvcrt ;-) Cheers, Jon ===== "Don't wait for the seas to part, or messiahs to come; Don't you sit around and waste this chance..." - Live jon_p_griffiths(a)yahoo.com __________________________________________________ Do You Yahoo!?

Windows NT/2000 Native API Reference by Nebbett
by Dan Kegel 02 Jan '02

02 Jan '02

I have the dubious distinction of having hired a friend back in 1997 to write perhaps the first PE compressor utility. It eventually became the core of http://www.neoworx.com/products/neolite/ (a competitor to Shrinker). He mentioned recently that he found "Windows NT/2000 Native API Reference" by Gary Nebbett http://www.amazon.com/exec/obidos/ASIN/1578701996/ to be useful in updating his compressor to handle .exe's that use some of the newer API calls. http://kt.linuxcare.com/kernel-traffic/kt20000724_77.epl mentions it, too, as do many posts in comp.os.ms-windows.programmer.nt.kernel-mode, so it appears to be useful. Just thought I'd mention that book in case anyone here hasn't heard of it. - Dan

What have I done to my debugger?
by Bill Medland 01 Jan '02

01 Jan '02

I'm getting the wrong sort of terminal. Why? I vaguely remember doing something to the registry settings for the debugger about a month ago but I can't remebber what. Since then I have not been tripping it anyway. However I am now investigating a problem that does trip the debugger. However it now comes up with an enormous terminal of some sort with terrible font and bad agreement between font and cursor positioning, so that important data disappears off the right of the screen before wrapping. However in the old days it used to use an xterm. I'd like to go back to that. Did I do that or is it a result of the stuff going on with the debugger? TIA Bill p.s. Merry Christmas to all.

Hello Waldek, Have a look at the following two messages from Marcus Meissner to wine-devel and wine-patches: Mon, 23 Jul 2001 09:08:31 -0400 http://www.integrita.com/cgi-local/lwgate.pl/WINE-DEVEL/archives/2001- 07/date/article-185.html Sat, 21 Jul 2001 09:14:03 -0400 http://www.integrita.com/cgi-local/lwgate.pl/WINE-PATCHES/archives/200 1-07/date/article-102.html You can probably also use the native MSVCRT.DLL, from your windows installation.

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 !
by Andriy Palamarchuk 29 Dec '01

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...
