Its main goal is to ski. It also serves to inform you of what's going on around Wine. Wine is an open source implementation of the Windows API on top of X and Unix. Think of it as a Windows compatibility layer. Wine does not require Microsoft Windows, as it is a completely alternative implementation consisting of 100% Microsoft-free code, but it can optionally use native system DLLs if they are available.

Thomas Brix Larsen decided to do a test of his own:</p> <quote who="Thomas Brix Larsen"><p> Motivated by my previous mail to the list, I have tried some more of my games with wine, and 2 out of 5 works perfect, but has some minor problems. Hmm, I guess a trace could be needed on some of them? But anyway here it goes: <ul> <li> Risk II: <br /> The "loading screen" displays, but: <ul><code> wine: Unhandled exception (thread 0009), starting debugger...</code></ul></li> <li> Empire Earth: <ul><code> winevdm: can't exec 'G:\Empire Earth\Empire Earth.exe': error=21</code></ul></li> <li> Europa Universalis 2:<br /> Is a bit slow but works perfectly. :D But can only be started from the konsole. If I try to start it from konqueror it says it can't find its data files. Something to do with konqueror not setting cwd? (or whatever it's called) The konsole is full of: <ul><code> err:ddraw:Main_DirectDrawSurface_GetSurfaceDesc Impossible/Strange struct size 0.</code></ul></li> <li> BattleField 1942:<br /> Alot of <tt>KEYFOUND: ... </tt> happens. But there is never displayed any graphic. Could this be something to do with the no-cd crack?</li> <li> Master of Orion 3:<br /> Game works perfect, some menu graphic missing, and mouse cursor ugly. I found something VERY interesting with this game and wine, the nebulas in game is different in wine and surely looks way better :D. </li></ul></p></quote> </section> <section title="Wine Lecture in Tel Aviv" subject="Wine lecture" archive="http://www.winehq.com/hypermail/wine-devel/2003/10/0179.html"; posts="1" startdate="11/10/2003" enddate="11/10/2003" > <topic></topic> <p>Shachar Shemesh is giving another lecture about Wine. If you happen to be in Israel you might want to check it out:</p> <quote who="Shachar Shemesh"><p> Last time the subject came up, someone suggested I make the date available so it can be published on the winehq.org site. </p><p> I'm going to give a lecture about Wine in a club called "Telux". The web site is at <a href="http://www.cs.tau.ac.il/telux/";> http://www.cs.tau.ac.il/telux/</a> (supposedly in Hebrew, but if you click the "Advanced lectures" english link at the left, you will get a pretty readable schedule even for non-Hebrew speaking). </p><p> The lecture will be on Nov 30th, at the Tel Aviv University. The lecture will be given in Hebrew. It will start 18:30 in the math building at the university. No advance registration is required, and no fee. </p></quote> </section> <section title="Top 30 on SourceForge" subject="Top 30 on SF" archive="http://www.winehq.com/hypermail/wine-devel/2003/11/0213.html"; posts="1" startdate="11/10/2003" > <topic>Project Management</topic> <p>Dimi Paun looked at some SourceForge stats and reported:</p> <quote who="Dimi Paun"><p> I've just checked and we're in Top 30 downloads over the last 7 days at SourceForge. More exactly, we're 28th most downloaded project, with over 20000 downloads. Not bad. </p><p> We'll need over 30000 d/l for Top 20, and over 50000 for Top 10. We'll get there sooner or later. :) </p></quote> </section> <section title="ALSA 1.0 Support" subject="Winealsa: Add alsa 1.0 support" archive="http://www.winehq.com/hypermail/wine-devel/2003/11/0166.html"; posts="1" startdate="11/09/2003" > <topic>Multimedia</topic> <p>Sylvain Petreolle posted <a href="http://www.winehq.com/hypermail/wine-devel/2003/11/0166.html";>two patches</a> for ALSA 1.0 support and put a call out for testers:</p> <quote who="Sylvain Petreolle"><p> This patch is almost complete, one macro hasnt been rewritten yet. </p><p> alsa09.diff must be applied to allow compilation with alsa 0.9. </p><p> Please test it with alsa 0.9 or 1.0 and give me the result. </p></quote> <p>Sylvain provided the patch for ALSA 0.9 support and then another for 1.0.</p> </section> <section title="Exec-Shield Problems" subject="Windows programs no more running with the new wine-glibc" archive="http://www.winehq.com/hypermail/wine-devel/2003/11/0301.html"; posts="4" startdate="10/13/2003" > <topic>Fixes</topic> <p>Sylvain Petreolle reported a problem with some threading changes Alexandre made:</p> <quote who="Sylvain Petreolle"><p> With yesterday cvs update, whch adds a glibc-threading detection, wine doesnt load a _Windows_ program anymore. </p><p> Using the RedHat rpm Yarrow kernel, I get : <ul><code> err:virtual:map_image Standard load address for a Win32 program<br /> (0x00400000) not available - security-patched kernel ?<br /> wine: could not load L"C:\\arakas.exe" as Win32 binary</code></ul></p><p> Funny thing : If I set up a symlink to the wine-glibc in another directory, it works without problems. </p></quote> <p>Mike Hearn asked, <quote who="Mike Hearn"> Well, are you sure you have disabled exec-shield for the actual wine binaries being used? </quote> Sylvain reported that he had never activated exec-shield and that things worked fine a week ago. Vincent Béron felt that was the problem too and explained a possible scenario like Sylvain described:</p> <quote who="Vincent Beron"><p> Exec-shield is activated by default, as well as prelinking. Read the release notes of Yarrow if you want to disable them. </p><p> What probably happened is you were lucky the first week, in that the random addresses assigned to the various libraries left 0x400000 (the default loading address for Win32 binaries) available, and with enough place to load what you loaded. </p><p> The loading addresses for system libraries are changed once per week (or 2 weeks, don't remember). System libraries added after the last complete assignation are assigned a random address at each load, so is you try to execute 10 times in a row the same program, it'll fail some of the time and succeed the remaining times. </p><p> I haven't been able to see that message with winelib applications (probably not in a codepath used for winelib apps, didn't checked yet). But it's pretty easy to hit if using Win32 apps. </p><p> Disabling exec-shield (either via setarch i386 or with the proc thing) works sometimes, depending on the loading addresses assigned to libraries. If something (libc, libm, libdl, etc.) uses that address, nothing Win32 will be usable. When exec-shield is disabled, new libraries will be assigned loading addresses starting at the lower value possible, but already assigned ones (via prelinking) will still keep theirs, hence possibly blocking execution. </p></quote> <p>Vincent replied a few days later with more information on the problem:</p> <quote who="Vincent Beron"><p> Sorry, forgot to come back to say how testing went. </p><p> The best workaround I found (from <a href="http://www.codeweavers.com/site/support/tickets/browse/?ticket_id=34072";> http://www.codeweavers.com/site/support/tickets/browse/?ticket_id=34072</a>) is to change the default prelinking options, so that the required address is still free for Win32 apps. </p><p> If you're hit by this, in file /etc/sysconfig/prelink, change <ul><tt> PRELINK_OPTS=-mR</tt></ul></p><p> to <ul><tt> PRELINK_OPTS="-mR --no-exec-shield"</tt></ul></p><p> The loading addresses chosen will be from 0x40000000, the default value on Linux systems, rather than trying to put the maximum of libraries before 0x01000000 (so that the first byte is always 0x00, rendering string buffer overflows mor difficult to exploit), hence crowding the area we want to keep free (0x00400000). </p><p> So far (little testing only, but still), I haven't had a problem with those settings, either running Wine or Linux apps. </p><p> Further reading in the referenced page shows Alexandre is in contact with some RedHat people, so hopefully they can come to a solution. RHEL 3 is affected as well, not only Fedora.</p></quote> </section> <section title="Volunteers Needed For LinuxWorld Booth" subject="LinuxWorld Expo NY" archive="http://www.winehq.com/hypermail/wine-devel/2003/11/0306.html"; posts="2" startdate="11/13/2003" > <topic>Project Management</topic> <p>Jeremy White put out a call for volunteers to help with a booth at LinuxWorld: </p><quote who="Jeremy White"><p> I somewhat impetuously requested a table for the Wine Project at the LinuxWorld New York expo, without really thinking if anyone could man the table. </p><p> We'll have a CodeWeavers specific area in another part of the expo, so we won't really be able to provide a lot of help (and won't need any extra promotion). </p><p> So, I was wondering if anyone wanted to go to New York and represent the Wine Project. </p><p> If so, let me know privately. If I don't hear anything, I'll quietly tell IDG <small> nevermind </small>.</p></quote> <p>LinuxWorld will be at the Javitz Center in New York City on January 21-23, 2004. </p> </section></kc>
