Most packages are built with Visual C++ (various versions). AFAIK only GRASS is built with MinGW and the installer using cygwin (as it's derived from the cygwin installer). Most library packages offer C APIs which are favoured over C++ API to avoid C++ ABI instabilities. Those libraries also include functions to free resources allocated by the libraries internally to allow the use of mixed runtime libaries (copeing with the "runtime library incompatibility hell" - not that we didn't have problems in that direction - mostly in GRASS). So Qt is and exception - it's built with Visual C++ 2008 (VC9). As are depending packages like QGIS and PyQt. Jürgen -- Jürgen E. Fischer norBIT GmbH Tel. +49-4931-918175-20 Dipl.-Inf.
