Introduction: Wine vs. WineLib Wine/Winelib provides the Win32/Win16 API's to a non-Microsoft operating system. The wine/winelib Win32/Win16 functions use X11 functions to perform the actual drawing on the screen. Wine and winelib are based on the same set of functions that implement the Win32/Win16 API. The difference between wine and winelib is the type of executable that is loaded into memory and executed. If an executable and any associated DLLs were compiled for x86 hardware running the Windows 3.x, 95, 98, or Windows NT (TM) operating systems, then Wine can use a special binary loader to load the program and the libraries into memory and execute it. Winelib on the other hand allows you to take the source for such a program and DLLs and compile it into the native format of a x86 Unix or Linux operating system. Winelib also allows you to partially compile the program and DLLs into the native format. For example, if you use a DLL from a vendor to provide some functions to your program and the vendor does not give you source, then you can use the Windows version of the DLL to provide the functions and compile the rest of your program in the native form for your system. Windows compilers assume a different structure than standard compilers. For example, standard compilers assume that the function main() exists and is the entry point of the program. On the other hand, windows compilers create a main() that issues an error message that states that windows is required for executing the program and the real entry point is the function WinMain(). As a result, winelib provides certain aids to generate code so that your program can be compiled and run as written for windows. For example, winelib generates a main() to initialize the windows API, to load any necessary DLLs and then call your WinMain(). Therefore you need to learn four basic operations to compile a windows program using winelib: compiling a simple program, compiling resources, compiling libraries, and compiling MFC. These skills are operations are explained in later sections of this HOWTO. Before you start porting your windows code to winelib, you need to consider whether you are allowed to port your program to winelib. As you compile your program using winelib, you will be combining software from several sources and you need to ensure that the licenses for the components is compatible. Hence in the next section, we will examine several legal issues. II. Legal Issues Disclaimer! I am not a lawyer. The purpose of this section is to make you aware of potential legal problems. Be sure to read your licenses and to consult your attorney. During the compilation of your program, you will be combining code from several sources: your code, winelib code, code from your vendor's DLLs (if any), and Microsoft MFC code (if used). As a result, you must ensure that the licenses of all code sources are obeyed. What you are allowed and not allowed to do can vary depending on how you compile your program and if you will be distributing it. For example, if you are releasing your code under the GPL, you cannot link your code to MFC code because the GPL requires that you provide ALL sources to your users. The MFC license forbids you from distributing the MFC source so you can not comply with the GPL license except by not distributing you program. On the other hand, if your code is released under the LGPL, you cannot statically link your program to MFC and distribute it, but you can dynamically link your LGPL code and MFC code and distribute it. Wine/Winelib is distributed under an X11-like license. It places few restrictions on the use and distribution of Wine/Winelib code. I doubt the Wine license will cause you any problems. On the other hand MFC is distributed under a very restrictive license and the restrictions vary from version to version and between service packs. If you plan on using MFC, there are three hurdles to legally using MFC. The first hurdle is how to legally get MFC source code on your computer. MFC source code comes as a part of Visual Studio. The license for Visual Studio implies it is a single product that can not be broken up into its components. The cleanest way to get MFC on you system is to use a dual boot Linux box with the windows partition visible to the Linux OS. Boot into windows and install Visual Studio. Since Visual Studio is installed on the computer, you have not broken it into its components. There may be other solutions, but I think this is the easiest. The second hurdle for MFC is the legality of compiling MFC on a non-Microsoft operating system. This varies with the version of MFC. MFC license from Visual Studio 6.0: 1.1 General License Grant. Microsoft grants to you as an individual, a personal, nonexclusive license to make and use copies of the SOFTWARE PRODUCT for the sole purposes of designing, developing, and testing your software product(s) that are designed to operate in conjunction with any Microsoft operating system product. [Other unrelated stuff deleted.] So it appears you cannot compile MFC for Winelib using this license. On the other hand, Visual Studio 6.0 service pack 3 (Visual Studio 5.0 is similar): 1.1 General License Grant. Microsoft grants to you as an individual, a personal, nonexclusive license to make and use copies of the SOFTWARE PRODUCT for the purpose of designing, developing, and testing your software product(s). [Other unrelated stuff deleted] So it appears you can compile MFC for Winelib using this license. The third hurdle is your legal right to distribute an MFC library. Check the relevant section of the license on redistributables and your redistribution rights. As I read the license, you only have the right to distribute binaries of the MFC library if it has no debug information and if you distribute it with an application that provides significant added functionality to the MFC library. Once you have examined the licenses for all of the sources used in compiling your program and have decided you can legally compile you program using winelib, you should probably experiment with your program running under wine to determine how much work will be involved in the port. The next section will give advice on estimating the amount of work required for porting your program to winelib. III. How Much Work? Wine and winelib use the same functions to implement the windows API; hence, if your program correctly runs under wine, it should run under winelib. However, wine/winelib is incomplete. You may have trouble running your program under wine. Many people have successfully run many programs under wine, so there is a good chance you will have no trouble. Wine executes the binary program that was compiled for a windows operating system. There are differences between the windows operating system and Unix/Linux operating systems. For example, in Windows 3.x, Windows 95, and Windows 98, the program has direct access to the hardware. A copy protection program that you purchased for your windows executable may use direct hardware access to write data to the disk. Hence, you may need to disable the copy protection in order to test your executable under wine. As a specific example, CrypKey is a copy protection program we use at Lumin Software. Our program does not execute under wine with the copy protection enabled. We disabled the copy protection, recompiled the windows executable, and our program works fine. CrypKey also works for Windows NT where it creates a service. Using wine with the --winver nt40 option "almost" gets the our program working with copy protection. At a later date, we intend to either implement the system calls in wine that are missing for CrypKey or to use another copy protection program that does work under Linux. During the execution of your program, wine prints error messages to standard error. These error messages include "stubs", which are windows API functions that have not been completely implemented. Depending on the the system call, these could be harmless or crash your program. Most of the common windows API functions have already been implemented, so you should have no missing API functions or only a few missing functions. If you intend to continue with the port to winelib, you will need to implement these API functions. After running your program for a while, you should have a good feel for the number of windows API functions that you need to implement. It is not necessary for you to implement the entire documented behavior of an API function in order to get your program to work. For example, many API functions have pointer parameters that are NULL in the common cases. If you always call the function with a NULL pointer for the default behavior, you can save yourself some effort by implementing a function that only works for the NULL pointer parameter. If you do this, make sure you test if the parameter is non-null and issue a warning for the non-null case. Also document in the source that the API function is incomplete. Once you have implemented an API function, submit the change back to the wine project so the next person to need the same function does not need to repeat your work. Remember, someone else wrote all of the other API functions that you are using, so you are benefiting from their work. Let other people benefit from your work as well. If you work for a company, you may need your company's permission to "give away" your work. IV. Compiling A Simple Win32 Program Wine and Winelib are written in C as is the MS Win32/16 API; thus, if have a program that calls only the Win32 API directly, you can compile the program using a C compiler and link it with some of the wine/winelib libraries. For examples of how to do this, see the directory libtest/ in the wine source tree. FIXME: to be continued. Describe spec file. Go through hello world example 1 and 2. V.

I am including them so that any one starting on MFC will have some documentation. Glean what you can and good luck. Before I write more detailed info on compiling MFC I have three questions. The info I have mentions three problems: 1. wine header files---what is the status of this? Do changes need to be made in the headers and if so, do I submit the changes back into wine cvs? Do the changes need #ifdef for C vs. C++ compilation? 2. DOS format files and no case distinction in filenames. Do the extensions Corel made to gcc 2.95 handle this? If so, how? 3. Microsoft extensions to the C++ syntax. Do the extensions Corel made to gcc 2.95 handle this? If so, how? If you have info that needs to be added, send me email at and I will add it. ===================================================================== THANKS Most of the information in this file came from postings on and from private e-mails. The following people contributed information for this document and I thank them for their time and effort in answering my questions. I also want to thank them for encouraging me to attack the MFC problem. CONTRIBUTERS: Damyan Ognyanoff Gavriel State Ian Schmidt Jeremy White From: Ian Schmidt Subject: Re: WineLib and MFC "Wilbur N.

Corel has done more MFC work than anyone (all of their applications which they are porting are MFC-based), and reportedly they have MFC itself compiled. I was just trying to get a moderately simple MFC-using app to compile, with moderate success (there are still some problems with MFC's headers after my patch, but at least they don't appear to be Wine's fault :) I did not try to compile MFC itself. > Which versions of MFC, if any? I have no idea what version Corel uses. As noted in my patch, I was fiddling with the headers for MFC 6 (from Visual C++ 6.0 Service Pack 3). Most of the stuff my patch addressed was for newer IE 5-related features, so I'd guess MFC 5 (VC++ 5.0) is likely what they used. > Is there any documentation on how to compile MFC for winelib?

Here's a few tips I discovered to get you started: - First off, run all the MFC headers (and source too if you try it) through a utility to strip out the DOS carriage returns. They cause havoc with GCC when it sees one after a line that ends with a \ (and MFC has many macros in it's headers that meet that description). If you don't have one, do a Google search on "fromdos" and you should locate some source (or it's fairly easy to make your own). - Use GCC 2.95.2, and the -fpermissive flag to make it less picky. 2.95.2 has some VC++-compatibility features that Corel paid for, and I believe more are forthcoming in future GCCs. - Use -I to add whereever you have the MFC headers at to your include path, as MFC apps typically use #include <> to access them rather than "". - Be prepared to have to rename and/or symlink headers, unless you compile on a case-insensitive filesystem :) - When you make install Wine it seems not to include all it's headers in /usr/local/include/wine. To have any chance at getting MFC going you'll want to use -I to add the include/ directory from the Wine source tarball to the path so it can grab everything. Sorry I can't help you more, but good luck! -Ian Schmidt ischmidt@cfl.rr.com From: Jeremy White Subject: Re: RFC: Wine 1.0 "Wilbur N.

After this bad experience, we were wondering --- approximately how many > man-hours did you spend compiling and changing MFC ? Urk. I misspoke. None of the developers here that I thought had working versions of MFC with Wine have working versions any longer. So, it may be a bit trickier than I led you to believe. We have it working pretty reliably with Twine, but not quite so cleanly (yet) with Wine. However, it really shouldn't be too difficult, and this is what I can remember of the process: 1. If you use a very modern version of gcc (2.95.2 or higher), I believe you will need to add the -relaxed flag to have any hope of compiling. 2. If you use an earlier version of gcc, you will need to adjust the many anonymous structs/unions that MFC supplies. We prefer this approach, because requiring very modern gcc implementations seems harsh to us. 3. You will need to adjust for the many type differences between MFC intrinsic types and the types supplied by Wine. For example, I believe that MFC expects a HANDLE to be compatible with certain scalar types, (and it is under Windows/VC, but is not with Wine/gcc). 4. The key procedure: add many -DNO_XXX flags to the makefile. If you start with Microsofts make file for MFC, convert it into a Wine makefile, and then turn on many of the flags they list there (of the form -DNO_XXX), your life will get much easier. Once you get it working with a few -DNO_XXX flags, you can go back and add them back in. 5. The best resource: you need someone who knows C++ very, very well. You occassionaly run into very obscure C++ problems where MS has extended the C++ standard and gcc has not. It really helps to have a guru on hand when you hit those. I hope this helps. Sorry for the earlier deceptive post. Jeremy From: Gavriel State Subject: Re: MFC questions "Wilbur N. Dale" wrote: > 1. Compile MFC. Several years ago we (Lumin Software) tried to > compile MFC.

At Corel, we had MFC compiled and running sample apps in WineLib in late 1998. It's mostly a question of the Wine headers, which weren't originally up to snuff. We did quite a bit of work on them, and most of those changes have been contributed back to WineHQ, so it should be pretty easy now. The other thing that was a big deal was getting the startup code working properly - since MFC needs to initialize static data *after* WineLib gets initialized. I believe that that issue has been addressed now on the WineHQ side with some of the work done on the .spec file tools recently. -Gav -- Gavriel State CEO TransGaming Technologies Inc. gav@transgaming.com From: Jeremy White Subject: Re: MFC questions "Wilbur N.

Despite your previous experience, and despite my earlier incorrect statements, I think that this is simpler than you fear. It's one of those tasks that's darkest before the storm - you spend all of your energy getting all the include files to work. Once you have *one* object file, the rest go much more quickly (alright, getting it to link is also a hairball of a job, but it's tractable ). If you're not in a hurry, getting MFC to compile, and having a documented procedure for compiling it is on our agenda for the relatively near future (see the Wine 1.0 task list). Jer p.s. Stick with Visi C++ 5. IMHO its MFC license is cleaner than that of VC 6. From: Gavriel State Subject: The MSVC++ 6.0 license Jeremy White wrote: > p.s. Stick with Visi C++ 5.

Actually, I just picked up a copy of MSVC 6.0 and it appears that they changed the license between the original release and the Service Pack 3 release - they removed the bit in section 1.1 about requiring that you be developing your software product only for use with a Microsoft OS. In any case, even the original license explicitly says that the MFC redistribution rights are *in addition* to the usage rights in section 1.1. The relevant portion of the original EULA: 1.1 General License Grant. Microsoft grants to you as an individual, a personal, nonexclusive license to make and use copies of the SOFTWARE PRODUCT for the sole purposes of designing, developing, and testing your software product(s) that are designed to operate in conjunction with any Microsoft operating system product.
