spec file definitions
by Rolf Kalbermatter 04 Dec '02

04 Dec '02

I have seen some definitions of functions in a spec file where a string was defined as str or wstr. I do remember that there was an issue with this depending if the string parameter was input only (eg. const) or an input/output parameter. Is this still valid and if yes how are the rules?

Installing Internet Explorer without windows
by Boris 04 Dec '02

04 Dec '02

I just tried installing IE 5.5 from setup.exe and it never seems to install properly without windows being installed or modifying files. It would be nice to install Internet Explorer without patching anything. I hope more people work towards that.

HTML Help and IWebBrowser status
by Ender 04 Dec '02

04 Dec '02

Hi all, I'm just posting a quick update on my various WINE work for those intrested. I currently have a working HTML Help viewer, which seems to work pretty well on everything I've tested so far. It does however need some more work to conform to the way the real HTML Help system works in Windows (eg, I havn't written an ActiveX control for it yet). Currently the HTML Help viewer requires an IWebBrowser interface, and only really works with an Internet Explorer installation - so I don't believe it should be commited into WINE proper yet. We don't want applications in our own CVS that require native dlls :) That brings me to my other WIP, de-QT'ing KHTML and turning it into a working browser implementation for WINE. So far this is actually coming along quite well, and besides a few points it definatly makes an effective browser and IE compatability seems to generally be good enough to keep the majority of IWebBrowser using applications happy. I've since abandoned my earlier hopes to keep the changes minor (in order to make it easier to backport fixes from the main KDE cvs), simply because it was making the code quite messy. Hopefully I'll have some beta code ready in a week or two, depending on how my free time goes. I have a few questions however, mostly I'd like to hear from Alexandre on whether he'll consider accepting this into CVS. A working IWebBrowser implementation is, in my opinion, a must - and my HTML Help work does require it - but there are a few points to consider: - It is C++. So far, all of WINEs dlls are plain C. Is this really a rule, or just a result of the current areas of focus? I can't really de-C++ khtml and co, but I'm unsure as to whether it's okay to add a requirement for a working C++ compile environment on core dll's. - It is somewhat big, several megabytes of new code. Hopefully I can chop it down after removing a lot of the unneeded KDE and QT code I currently have #ifdef'ed and commented out. Cheers, Ender

Reducing the header maze (warning: long, unsuitable for children)
by Greg Turner 04 Dec '02

04 Dec '02

I'm working on Ove's comhdr1 & comhdr2 patches. So far, so good, btw -- I have it compiling against yesterday's CVS (recent commits are not folded in yet). I'll submit after I kick the tires a bit and make sure everything seems to be working (otherwise, I'll probably post it here and ask for help). Anyhow, this project has served to remind me just how deep, and how confusing, the maze of wine headers can really be. It's clear to me that lots of header inclusions are just historical remnants, that no longer serve any purpose, and, conversely, that many implicit header dependencies exist that happen to be hidden, and missing (i.e., X.h needs Y.h, but all references to X.h happen to occur after Y.h was already included, so there's no compile failure). A third kind of unnecessary (but arguably correct, in many cases) dependency is created when an include file is pulled in that is already pulled in by some prior include... This negatively affects wine development because (a) it's hard to change things, the headers break too easily, and (b) the make process rebuilds stuff that doesn't need rebuilding when things change (unavoidable, to an extent, of course, but perhaps it's too much right now). Now, here's my question: couldn't we build a script to automatically fix some of these problems? Imagine this pseudocode as a bash script, makefile, or something along those lines: o gather and create a table of all .c -> .h and .h -> .h dependencies o for each file: o one by one, try removing each reference to a header, and see if the affected units still compile. If they all do, permanently remove that reference, but remember it was there at this point we should have approximately the minimum number of header references in the code to compile wine. But some of the header references we eliminated were probably legitimate dependencies, event though we compiled OK, as mentioned above... so now we: o for each header, try to compile a "Hello World" which includes just that header file. If it fails (or even generates warnings): o for each header reference that was eliminated, try putting it back in. If still failing, try different combinations (this could become a really nasty computation with all kinds of permutations possible, but if certain simple tricks don't work, we can just give up). o if we couldn't find any way to fix it, mark the header for human review. This should ensure that each header can actually be run through the compiler all by itself -- that is, that it #include's any headers it relies on to compile. Finally... o A human picks up the pieces and fixes the breakages o The whole heuristic can start over, now, until the results start to look repetitive or trivial... I can think of some reasons this might not work out so well as I might hope, but... what do you guys think? is such a test meaningful? Is there some tool that already automates this type of investigation, or some better way to achieve the same thing? Would it be, in your opinion, too much work for too little benefit? FWIW, I can probably think of more enjoyable tasks to spend my time on... but OTOH I am really tired of waiting for wine to build on my aging pc -- anything that could speed up the build process would probably save me some from some discomfort, and others too. (At least there's no C++ in there; I'm rebuilding my system lately (I killed it over the holidays messing with glibc), and building stuff like KDE, mozilla, sun-java, and openoffice makes wine look pretty darn svelte! g++ 3.2.1 just crawls; the more "object oriented" the source is, the longer it seems to take to compile... :( ) Just "thinking out loud," probably a terrible idea, but let me know what you think, anyways... -- gmt p.s., I was kidding about unsuitable for children... but then, not sure why children should want to read this -- or adults, for that matter :P

Yes, it would be possible to resolve imports directly through the ELF tables and avoid our own separate import mechanism; basically this would be a PE-aware ld.so. It's quite a bit of work though, and portability is an issue. In any case it's for after 1.0 IMO. -- Alexandre Julliard julliard(a)winehq.com

Portability to NetBSD shouldn't be an issue, as they seem to have already implemented it :-) See http://chiharu.haun.org/peace/ http://groups.google.com/groups?selm=20020516061929.5DA943C110%40gabi-n.hau… et seq. http://www.freebsd.org/cgi/man.cgi?query=compat_pecoff&manpath=NetBSD+1.6 - Dan

Bill, Unless I missed the whole point, you gave the answer before asking the question. ./configure should have been ./configure --disable-debug -- Jeff S _________________________________________________________________ MSN 8 with e-mail virus protection service: 2 months FREE* http://join.msn.com/?page=features/virus

Compiling out the debug messages
by Medland, Bill 03 Dec '02

03 Dec '02

I know I don't know what I am doing, but.. The documentation says that to compile out the trace, warning and fixme messages I should specify --disable-debug when running configure. So I try ./configure make depend make <build an rpm and install it on another machine> <run wine> <stare at the fixme messages, swear etc.> I presume that if I look for example in the dlls/user/Makefile at this stage I should see NO_DEBUG_MSGS and NO_TRACE_MSGS somewhere, but I don't. Please can someone explain how this is supposed to work and where I have probably gone wrong. (e.g. where should I see the NO_DEBUG_MSGS) Bill Medland

For me that's not necessary; maybe for others who would like to review the patch, but I doubt many people are going to review the auto-generated stuff anyway.
