OT - a free windows screensaver?
by lawson_whitney＠juno.com 14 Jun '01

14 Jun '01

Good day! After I got both my legs broke April 27, my computer and I have been a bit exposed to a small segment of the public, and everybody loves my screensaver. ftp://ftp.ibiblio.org/pub/Linux/utils/console/lockvc-3.9.1.tar.gz Of course, I may have a hard time to get them to install Linux just for a screensaver, so I thought I might see about porting it to windose. A sample or something to plagiarize from would be good, I think. I haven't figured out how to work mingw either, but maybe inspiration will come.

interrupts
by Eugene Toichkin 14 Jun '01

Hi! I have to run the add-on card with Windows controlling program on my linux box. That card generates the interrupt and requires some port addresses. Is any way to configure WINE to run that kind of application on Linux host? -- Best regards, Eugene Toichkin ugin(a)itc.mecom.ru

Drawing problems with ControlSpy
by Guy L. Albertelli 14 Jun '01

14 Jun '01

With today's CVS (last patch was "wine/ dlls/gdi/wing.c dlls/kernel/comm.c dlls/ ..."), the following problems exist in the ControSpy (REBAR) test program: Problem #1. Using native version of "commctrl,comctl32", get the following fault: /home/albertel/t1/wine/wine -managed -winver win95 -dll commctrl,comctl32=n G:\Rdhat\test-pgm\controls\rebar.exe Could not stat /mnt/winflp (No such file or directory), ignoring drive A: fixme:pthread_kill_other_threads_np Could not stat /mnt/winflp (No such file or directory), ignoring drive A: WineDbg starting... on pid 8064ef0 ......

Please report this. ##normal exit from wine## Problem # 3. Still with native comctl32. With more than 1 band in a row, when you drag a band from left to right, the band being uncovered is not fully repainted (suspect InvalidateRect too small). This is especially visible if the band being dragged is a different color. It is also sensitive to the speed of the drag. Attached is a control file to create different color bands in a row. If you need any more information, let me know what. I will be doing more work tomorrow night. Thanks, Guy

> >Log message: > Force invalidating of siblings children on expose event. > This seems to allow ControlSpy (rebar) to draw its children again, but exposes some other drawing problems. The symptom is that certain areas do not seem to be invalidated correctly. If the window is overlayed with another the everything is redrawn correctly. I will attempt to get documentation later tonight. Thanks, Guy

RE: Help needed

I'm sorry for not answering earlier. I saw your message but I didn't have time to answer it at the time and then a forgot about it. In truth I wasn't very eager about answering either since I have answered far to many people that just asked questions and then didn't contribute anything because I guess that they felt it was to difficult or to much work. I didn't notice that you were from Digital either, but after reading Kernel Cousin Wine #97 I was made aware of that fact. While it is possible that you are yet another of those people I talked about above, since you are from Digital I will take some time to answer your questions. Note however that I'm not at all unwilling to answer questions. It is just that it has felt like a wasted effort in the past. > We are planning to port wine onto Tru64 Unix. I have some > basic Questions. OK. Sound good. > Can you tell me how to go about it. Yes. But it is better if you ask more specific questions. > How do we start. You try to get it to compile and link. This shouldn't be to difficult. While I never used Tru64 I expect it supports all things Wine will need. > How big > is the task and Well, if you want the emulator (Wine) to work it will be a humongous task, since you will have to emulate x86 instructions on the Alpha among other things. However if you just want the porting tool (Winelib) to work it will be a little easier. Still, you must be aware of a few thing. * Wine is not 100% byte order clean. However there have been some attempts to port it to Sparc which is big endian so don't if I think it is that bad and the remaining problems can be fixed without to much effort. * Wine is not 64 bit clean. This is a little worse especially since Win32 often stores pointers in 32 bit integers and this problem really can't be solved in a good way, since extending the size of the storage is not possible at least not if you want to be able to implement a x86 emulator in the future. However I guess it will be possible to force all memory usage to be in the lower 32 bits of memory to be able to cope with truncated pointers. * Then of course you have Tru64 specific problem. However I don't expect them to be so bad. > how to start about it.. Well as I said. Try to compile and link it. Then try to get some of the simple examples in wine/programs to run.

Re: virtual memory problems with Linux 2.4.5

Mike McCormack <mike_mccormack(a)start.com.au> writes: > your patch produced a yes, BUT when i changed the offset value to > 0x400, and it failed ... see new patch below. That's a bug in glibc 2.1.3. This is from the mmap64 source: [offset is in ecx:edx] testl $0x3ff, %edx jne L(einval) shrdl $12, %ecx, %edx /* mmap2 takes the offset in pages. */ shrl $12, %ecx But of course 0x3ff only tests 10 bits, not 12, so if bits 10 or 11 are set they will be silently dropped. This has been fixed in glibc-2.2. Another related problem is that even without this bug, mmap64 will always refuse to do an unaligned mmap, even if the kernel might have accepted it (with kernel 2.2.x for instance). Maybe the best solution would be to directly call the mmap syscall instead of mmap2 when mapping executables, this would fix both problems. -- Alexandre Julliard julliard(a)winehq.com
