PORTING Qt TO OTHER PLATFORMS Read this file if you want to port Qt to a new platform or C++ compiler. If you come across any problems, feel free to send mail to qt-bugs@trolltech.com. REQUIREMENTS The new platform needs Xlib for X11R5 or newer. Motif is not required. If it is not a Unix system (for instance VMS) things may get complicated. Porting to other Unixes is generally straight-forward. Qt requires that your C++ compiler supports multiple inheritance and templates. The compiler must recognize the .cpp extension. Exception handling and RTTI (Run-Time Type Information) are not required. Expect problems with old CFront-based compilers. PATCHES Please send us the patches you had to make so we can add them to the code base; then we can support the new platform in an orderly manner. (We want Qt to run on as many platforms as possible, but _not_ if that involves incompatible patches for the same platform floating around the net.) Further, we would like to have copies of all Qt-related files on ftp.trolltech.com. PORTING INSTRUCTIONS In the configs/ directory you will find several build configuration files for all platforms supported by Qt. Start off with one the existing files in configs/, rename it, and change it manually to fit your system. For example you may copy configs/solaris-cc-shared-debug to configs/solaris-cxx-shared-debug If possible try to modify all four configuration files. Modify qt/src/tools/qglobal.h as required: you need to ensure that _OS_whatever_ is defined. We've done it for many platforms in the past, those should be okay. If you are using a compiler we don't detect it's probably a good idea to add a _CC_whatever_ too (even though you don't need it at once). There are also some size-dependent types (Q_UINT32 and so on), make sure they're right for your system. Some compilers emit bad warnings when they compile Qt. If yours does, and the code in Qt is sane, please use a #pragma or two to shut your compiler up. (This is a good reason for wanting the _CC_whatever_ define above.) Alternatively try using compiler option flags. Make a unified diff (diff -u) and send the patch and the configuration files to qt-bugs@trolltech.com. For most Unix varieties, that's all. Some may need some include file tweaks. Good luck, and again, feel free to send mail to qt-bugs@trolltech.com.
