Could someone give me some pointers to info on this matter. Thanks in advance for your help.

The simplest solution is to use only standard mechanisms and classes. Given that you have a standard-compliant compiler on each platform, programs will be source-code compatible and should have the same side effects (behaviour).

Could someone give me some pointers to info on this matter. Thanks in advance for your help. Silviu Simple. Don't write any platform-specific code! :-) Seriously, though...do you have to provide a GUI? Handle files/directories? Databases? Manage system resources? If yes, then you'll need at least *some* code that is platform-dependant, which means it will be written differently on each platform you target. Depending on your needs, there is third-party, cross-platform software out there. Some SDK's are writtin with this in mind, so that most porting work is simply a matter of setting up your projects differently. You also have to deal with what compiler(s) you'l be using, and that may change how you do some things. If you don't have to worry about those things, then simply write your code such that it follows the C++ standard (as discussed here), and avoid any platform-specific junk (like MFC in VC++ apps.) Check Google for cross-platform software if you need it. Best of luck! -Howard Back to top John Gabriele Guest Posted: Wed Oct 29, 2003 10:18 pm    Post subject: Re: How to write C++ code that compiles in Windows/Linux silviu wrote: Quote: Hi All, I have to write C++ code (server code) that will compile/run on both Windwos and Linux OS's.

Silviu If you must use platform-specific code to handle the sort of stuff Howard mentioned, do your best to compartmentalize that code away from the rest of your program's logic. -- --- remove zees if contacting via email --- Back to top Sandeep Guest Posted: Thu Oct 30, 2003 3:08 am    Post subject: Re: How to write C++ code that compiles in Windows/Linux Just regular C++ should work on both platforms. Just be careful about the case insensitivity of the Windows file system. If you are planning to write GUI code, the best option is wxWindows (www.wxwindows.org) Sandeep -- http://www.EventHelix.com/EventStudio EventStudio 2.0 - System Architecture Design CASE Tool Back to top Medi Montaseri Guest Posted: Thu Oct 30, 2003 6:07 am    Post subject: Re: How to write C++ code that compiles in Windows/Linux [email]thelinuxguy1997 (AT) yahoo (DOT) com[/email] (silviu) wrote in message news:<f53c2ba1.0310291002.2f266beb (AT) posting (DOT) google.com>...

Thanks in advance for your help. Silviu I'd also recommend: 1- Layer your code so that you'll tuck all the OS specfic code in that class, perhaps an OSIL (OS Independent Layer) on top of OS1, OS2, ...., etc. 2- Use a common compiler if possible. For example if you will be using GCC on Linux, see if you can use the same GCC for your Windows. This way you let the compiler and glibc++ authors figure out the differences and you stay out of that game. 3- If you must use Microsoft VC++, use their latest 7.x as 6.x does not have all the STL or their implementation might differ a bit. 4- If you use fancy C++ features, you might run into some issues; For example RTTI is definitly different in GCC and VC++. 5- If you ever plan to port to 64 bit, whach out as Microsoft is not up to speed on that for example in VC 64 bit, a long is still a 32 bit. 6- Work with iostream an not printf stuff as their format specs are different. If you use GCC on both, you don't have to worry about many of above stuff Now if you use Win32 API, you'll find that Microsoft has so many Helper Functions that you'll be both confused and for ever hooked on their products.... Just use plain o-C++ Back to top Display posts from previous: All Posts1 Day7 Days2 Weeks1 Month3 Months6 Months1 Year Oldest FirstNewest First         C++Talk.NET Forum Index -> C++ language (comp.lang.c++) All times are GMT Page 1 of 1   Jump to: Select a forum C/C++----------------C LanguageC Language (Moderated)C++ Language (Moderated)C++ language (comp.lang.c++)C++ language, library and standards Non-English C/C++ Newsgroups----------------C++ (German)C++ (French)  You cannot post new topics in this forum You cannot reply to topics in this forum You cannot edit your posts in this forum You cannot delete your posts in this forum You cannot vote in polls in this forum Powered by phpBB © 2001, 2006 phpBB Group SEO toolkit © 2004-2006 webmedic.
