Qt is an object-oriented GUI toolkit written in C++. This version (the Qt Free Edition for Unix/X11) may be used free of charge for developing Free (non-proprietary) Software on Unix under the X Window System. The Trolltech home page has more information.
Qt-2.3.1: description + notes
NOTE: The threaded Qt libraries (libqt-mt.so) uses recursive mutex emulation code, since IRIX 6.2 does not support mutex types. Everything should work, but applications compiled against a "normal" IRIX 6.5 threaded version of Qt may not work with the freeware qt-mt library, and vice versa.
NOTE: Developers intending to use this distribution of libqt for application development should be sure to read the information below. Users installing libqt for the runtime environment only need not read any further.
Developers intending to use this library for development of other freeware packages or their own software applications will need to be familiar with a few peculiarities due to the way that this library is packaged and installed. The reasons for this installation strategy are described further in the fw_common product release notes.
The header files and libraries in this package are installed into /usr/freeware. This means that when building software using this distribution of libqt you should be sure to do the following:
This flag will cause your compilations to correctly find the library's header files at compile time.
- Include the following flag on your compile lines:
- -I/usr/freeware/include
Include the following flag on your link lines:
-L/usr/freeware/lib32 (if using n32 ABI) -L/usr/freeware/lib64 (if using 64 ABI) This flag will cause the linker to correctly find the library's archive or shared object files at link time.
Additionally, include the following flag on your link lines:
-rpath /usr/freeware/lib32 (if using n32 ABI) -rpath /usr/freeware/lib64 (if using 64 ABI) This flag will allow the binary to locate the shared object library files when the application is run. This is required since the shared objects are stored in these /usr/freeware subdirectories which are not searched by the run-time linker by default.
Finally, if you are building an installable package for inst (contributing to freeware, for example) be sure to make your package depend upon this package. Add the following line to your spec file: prereq ( fw_qt.sw.lib 1270000000 1289999900 ) Following these guidelines will allow your application to safely and easily use the software in this package.
