That's certainly a possibility. If you want a more temporary change you could also use regapi to change the config branch in the registry. Yet another possibility would be to add a "fast" mode to the debugger where it wouldn't load symbols or anything, simply setup the environment and launch an application. This could be the first step towards making it change debugmsg options during execution too. And all these solutions are potentially much more generic than the few existing options, since you could use the same mechanism to change just about anything in the configuration. -- Alexandre Julliard julliard(a)winehq.com

If people really want more flexibility there are many ways of doing that; but hard-coding the options in kernel32 isn't one of them. -- Alexandre Julliard julliard(a)winehq.com

Yep, and there will still be other changes that will break everything and confuse users (think window management for instance); that the reason we are not at 1.0 yet. > And why don't you get rid of --managed then either ? It will happen, don't worry... > And how exactly does this break dll separation ? Because with these command-line options kernel32 must know about and export information specific to x11drv. Also there's a larger issue of mechanism vs. policy; if we want to be able to use the same set of Wine libraries for multiple usage (wine loader, Winelib apps, mp3 players loading Windows dlls, etc.) we need to move all policy decisions to the higher layers. We cannot have kernel32 enforce a specific command-line usage, since this doesn't apply in all cases. For another instance of the same issue, see the discussion about the deferred debug trace a couple of weeks ago: we need the Wine libraries to provide the *mechanism* to display tracing and other informations, but the *policy* of when and how to switch tracing on or off must be moved to higher layers (like the debugger) instead of hardcoding a magic key sequence in user32. > Can't we solve this in another way ? > (i.e. maybe keep cmdline options for Wine, but don't use them for Winelib > apps) > Getting rid of all command-line options is not really an option IMHO. > They are just way too useful. There are tons of settings that can only be set through the config file; why are the few remaining options so much different that you need to set them on the command line? and how do you pass options when an app is not launched from the command-line (like from another Windows app, or from a desktop icon)? -- Alexandre Julliard julliard(a)winehq.com

All command-line options are going to disappear at some point, first because they are problematic for some Winelib apps, and second because they break dll separation. -- Alexandre Julliard julliard(a)winehq.com

You know, I did exactly that (looking at the assembly and running performance tests) when implementing it; it may be possible to improve it more by optimizing CPU pipelines usage, which is something I don't know too much about. But I strongly doubt you can improve it by only looking at the C source... --=20 Alexandre Julliard julliard(a)winehq.com

problems compiling mfc with winelib
by Doug Alcorn 22 Mar '01

22 Mar '01

I have a small apps with only about half a dozen dialogs. It was originally developed in MS-DevStudio. Our desire is to use the same code between MS-Windows and Linux/Unix using the winelib. This app is derived from CWinApp and uses mfc for all the widgets. I'm told it would take too much effort to redo the app without mfc (I'm not a windows programmer, and don't know much about all that). So, my assumption based on reading winehq.com is that I need to compile the mfc using winelib. I got all the code over to my linux box and converted all the files/directories to lowercase only. I got the mfc, atl, and some other include directory that was under "Program Files/Visual Studio/VC98" (or something similar). I ran winemaker on the mfc directory and successfully got the configure script built. The problem is getting the make files built. I had to define both CFLAGS and CPPFLAGS "-D_WIN32 -DWIN32 -D_WINDOWS -D_MBSC" in the environment. Here's my configure line: $ ./configure --with-win=/path/to/wine/sources --with-atl-includes=/path/to/atl/includes --with-mfc-includes=/path/to/parent/of/mfc/includes It goes allong pretty well until it checks for afx.h. That's when it bombs majorly. I get pages and pages of compile time errors in the config.log. Lots of parse errors, syntax errors, scoping errors, redifinitions... lots of stuff. Am I right that I have to compile mfc? Is this something that most developers using winelib to compile windows programs do? Are there instructions for doing so? At this point I'm totally stumped. I'm not about to start debugging mfc. I'll re-write the app before I do that. What is the suggested course of action? -- (__) Doug Alcorn <doug(a)lathi.net> http://www.lathi.net oo / PGP 02B3 1E26 BCF2 9AAF 93F1 61D7 450C B264 3E63 D543 |_/ If you're a capitalist and you have the best goods and they're free, you don't have to proselytize, you just have to wait.
