Winelib - MFC application
by jaymz＠free.fr 02 Dec '02

02 Dec '02

I'm currently trying to build an MFC based-applications using Winelib. I (almost) successfully compiled the MFC, and get an mfc.dll.so file. Here are the few troubles I had or still have: First for compiling the MFC: --------------------------------------- - I had to uncomment PSH_WIZARD97 in /wine/prsht.h - The packing pragmas looks handled by gcc-3.2.1, so we may remove all modifications made by winemaker - I had to force winnt.h to use nameless struct and unions - I added #define EDEADLOCK EDEADLK in /wine/msvcrt/errno.h - I linked _alloca() to alloca() function - There was a conflict on HKEY type between <afxres.h> and <wine/windef.h> - Some little others syntax issues like: __try __expect, asm {}, unsigned short(x), (LPCTSTR)CString ==> it worked then, using some additional defines as suggested in the Winelib documentation page. Then for my MFC-based application: ------------------------------------------------- - Winemaker tries to link with libmfc.so, but by default we have a dll, so i just symlink it to mfc.dll.so - I first tried winemaker default settings on my app, but it creates two targets with the same name (the dll and the executables), so I had to override this using interactive mode - Then I encountered the MFC initialization problems (a crash in dllname() when loading my application .so), so I added the wrapper using winemaker - Even when using the wrapper, it crashes at startup when trying to load my application dll. - The backtrace is something like dllname (from libmfc.so) operator new ... Init (from /gcc-3.2.1/libstdc++-v3/src/ios.cc:211) ___static_initialization_and_destruction_ ... _dl_open ... WinMain (from myapp.exe_wrapper.c:83) __wine_exe_main (from myapp.exe.spec.c:129) start_process call_on_thread_stack - Winelib must have been initialized, but the problem stills here ? Any suggestion ? - I then tried to remove linking with libmfc.so but using only the mfc.dll.so (I had to fill the mfc.dll.spec file to export all the symbols, using weird mangling rules), but it then hook in the msvcrt.dll in an infinite _lock loop ? I'm a bit lost with this error, as it's not in an easy-to-debug code area.... Any advices are welcomed !

Screenshots v0.1
by Brian Vincent 02 Dec '02

02 Dec '02

I've gotten a lot of great screenshots over the past few weeks. I've put together a preview you can find here: http://www.theshell.com/~vinn/ss/preview.html Be warned, the format isn't the best, the thumbnails aren't even close to optimized, I only looked at it in one browser, and it might even steal your lunch money. Random notes: - there's lots of great shots not on the thumbnails page - most likely there's a reason, not 800x600, didn't scale well, or I simply overlooked it - you can find all of the screenshots at: http://www.theshell.com/~vinn/ss - the images predominantly are PNG, though there are quite a few JPEGs. No GIF. - Special thanks to: Thomas Wickline Carlos Lozano David Buchmann Guido Grazioli Ender Juliasz Gonera Michael Krasucki Mike Hearn Rick Romero Robert Shade Rory King Tony Lambregts tavis Okay, if you've read this far maybe you're expecting something to prompt discussion. One of the things you'll notice is there's a lot of screenshots on there there almost certainly don't run out of the box. In some instances the folks above listed exactly what they had to do to make it run. Personally, I don't think it matters. We already have the apps DB and the proposed "Gold/Silver/.." apps list, I really don't think we need more than a link to one of those. Also, a few weeks ago there was a lot of discussion of a new WineHQ site. Any progress on that front? -Brian Vincent

RE: strcat+strcat+strcat == baaad

Since the do exists on some platforms (OpenBSD and FreeBSD) the obvious place to put them would be library/port.c like any other function that doesn't exists on all platforms. Just remember to add detect in configure.ac and use the HAVE_ macro in library/port.c As for (re)writing them. Why not just borrow the source from FreeBSD or OpenBSD. They both have licenses compatible with Wine. No need to reinvent the wheel.

Adding support for xxx_test.exe all
by Francois Gouget 02 Dec '02

02 Dec '02

When running the tests on Windows you can either do 'xxx_test.exe' which gives you a list of the available tests for this executable, or 'xxx_test.exe foo' which runs test foo, and only test foo. So I propose the following patch which makes it possible to run 'xxx_test.exe all' which runs all the tests implemented by that executable. Do others find this patch acceptable? Useful?

Wine REALLY emulates Windows (was: Texture corruption in Wine)
by David D. Hagood 02 Dec '02

02 Dec '02

I am continually amazed at how well Wine emulates Windows - for example, my recent experiences show Wine has the whole "Just re-install it, it will fix it" thing down pat! 8^> To recap the story thus far - Several months ago, I was able to play Halflife- Opposing force all the way through under Wine. Then my motherboard died, and I replaced it with an SMP mobo. I had to do some tweaks to my kernel, my X server, and to Wine to get everybody back up. But when I was done, and I went to install Halflife-Blue shift, the textures were screwed up. So were the textures in OpFor. I tried booting UMP, I tried scraping the fake Windows install and reinstalling, to no avail. Friday, I downloaded Transgamings WineX in an effort to remove a few variables from the matrix. WineX ran BlueShift and OpFor flawlessly - exonerating my X server, kernel and system. So, this morning I set about trying to find out what changed in Wine. I went back and pulled Wine as of the 20020902 tag, and rebuilt. Then I did my usual install method: rm /usr/local/winelibs /usr/local/include/wine /usr/local/bin/win* -R && make install Still had no luck with Halflife - still had corrupted textures. So, I moved my fake Windows and .wine directories out of the way, created new, empty directories, copied my old .wine/config over, re-installed the Wine default registry, and re-installed Blueshift. And it worked. OK, maybe the install had problems. I moved my new fake windows and .wine directories out of the way, and moved the old directories back. And still, it worked. All textures were fine. Note: at this point, I should have had the OLD install of Blueshift back in place, and the old registry. The very one that didn't work five paragraphs ago. So, I went to my image of the current CVS of Wine, rebuilt it, and once again did a rm /usr/local/winelibs /usr/local/include/wine /usr/local/bin/win* -R && make install. And still, it worked. In theory, I should have been back to where I started from. Except where I started from didn't work. Where I was did. Now, I am at a loss as to what could have changed from the non-working state to the working state. Like I said, Wine has the whole Windows "mysterious changes" thing down pat! But it works. As Bugs Bunny said, "I don't ask questions, I just have fun." So, I am off to kill some headcrabs. But for the life of me I don't know HOW what I did fixed it....

It's workable, A better solution would be to port the source code to the LP64 model. It is entirely possible for to support all of LP32 (Win32 and "Unix32"), LLP64 (Win64) and LP64 ("Unix64") in a sane way. I don't think it is worth the effort to support LLP64 beyond having a "-flong-int" flag to get a working version to show as a prototype that porting is indeed possible. > and Win64 will not > bother us for some time... True. Microsoft doesn't seems that eager pushing Win64 either...

That solves the libc problem however compiling with -flong-int also means that it will be impossible to call other libraries, which means that it will be a little hard to use Unix specific library to have extra functionallity under Unix. But sure having a -flong-int flags is nice but it doesn't solve all problems. Perhaps would be good to push for its addition even now, it might take a few years before standard GNU C installation supports it.

"not enough space in GDI heap" / forking vstlib programs
by Kjetil S. Matheussen 01 Dec '02

01 Dec '02

Hello, as I just announced I'm developing a vst-server, that loads and runs windows vst plugins. But after loading and unloading a lot of plugins, I get lots of "err:local:LOCAL_GetBlock not enough space in GDI heap 01f7 for 24 bytes" errors. I understand that the cause of this error is caused by a memory leak in a windows program. However, in the vst-server, there is no way to control memory leaks in the plug-ins, as those are made by various groups and persons. So is there a way around this error. Doing a fork for each new plug-in perhaps? Is that safe? I want to do that also to avoid having a plug-in crash the vst-server. --
