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 March 22, 2001

March 22, 2001

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.

Re: Port to OS/390 mainframe USS?
by James Hatheway March 22, 2001

March 22, 2001

Hello James, > I am not real clear about the difference between the PE loader and the > WINELIB, but then, I am also unclear as to why my user would want to run a > Windows app on the mainframe in the first place. Sorry, I should have been a bit more descriptive with my answer. The PE loader is used to run executable files that were compiled to be executed in Windows/intel environment (standard windows apps). It handles the 'magic' of loading a windows executable including the necessary dependecy checking, dynamic link library loading, etc. Once the executable is loaded and all dependecies to DLLs resolved and loaded the program is started and runs with the same intel code that would have executed in windows. Whenever the app makes a call to a Windows API function, the code actually is handled by WINE code (or the native windows DLLs if that is the user's configuration) That is why WINE is not an 'emulator' rather a reimplementation of the Windows API. That is also why it is tied to the intel platform, since it is still directly executing intel code. Since WINE is comprised mainly of a reimplementation of the Windows API, it can also be used as a porting library for application developers. WineLib allows a developer to recompile his Windows source so that it will run on other unix platforms (including other CPU architectures than intel). The problem is that not as much work goes into the WineLib side of WINE than does go into the mainstream WINE side of things. My understanding is that WineLib has been built on Solaris/Sparc, powerpc, and s390 with varying degrees of success. Also I don't know if the patches that got these platforms to build are actually in the main CVS tree. Searches through past WineHQ discussions can bring up the names of those who worked on this stuff. So, unless your user has access to the source code to his app, he can't use WINE to run his app on the S390. I'm not sure if WineLib has advanced enough to support his app on the S390, and in fact Wine itself might not support his app on intel either, that is a case by case thing. (although WINE works quite well for a lot of apps) Finally I have no idea why a user would want to run a windows app on a s390. ^_^ > Is there someone at Ulrich that I should be talking to?

Hi! David A. Solomon, the author of "Inside MS Windows 2000", is comming for a seminar 2-3 April here in Oslo. He is a friend of one of mine friends so I got a free ride. I am not envolved in the wine development (I would love to if I had the time) and I don't have any experience with the win32 API or any windows programming. But when I got this invitation my first thought was you guys, who develop wine. So if anyone want me to ask him about anyhing about windows and the win32 API, I would love to so. David is an expert when it comes to win32 API and he has the source codes for windows. http://solsem.com Best Regards, Natanael Copa

Port to OS/390 mainframe USS?

Will there be a port of WINE to OS/390 mainframe USS? LINUX runs fine under USS, so it would seem that WINE should run there as well. Has anyone done this yet? Thanks James Robinson james.robinson(a)crowley.com
