Qt installer framework is a set of libs to make SFX installers. Installers usually contain 7zip-compressed archives. Obviously, Qt installer itself is built using this framework. | ||
Warning 1: KSC has a bug. It makes the computed values be int32_t. Of course their type should be either explicitly specified by a programmer or derived automatically. The workaroind is to just replace all int32_t to int64_t in sources. | ||
Warning 2: don't use this spec on Linux against Qt distribution with overcommit enabled unless you have lot of RAM (> 12 GiB). There is a severe memory leak somewhere (currently I have no idea where exactly). The leak is present in both C++ and python-compiled code. In python even if I have patched the generated source to explicitly free all the `bytes`, `BytesIO`s and `KaitaiStream` objects the leak is still present. At least it is neither in `bytes` nor in `BytesIO`. In C++ I have not patched anything but used move semantics to free the stuff since std::unique_ptr is used. The leak is still present. IDK where it is and how to fix it. | ||
