This repository contains all the data used in GCompris that is not shipped directly:
voiceswords(contains image dataset used for lang, hangman...)background-music
The scripts to generate rcc files are in the scripts folder. Navigate to the scripts folder and run main_generate_rcc.sh. You may need to adjust the RCC variable in the script to the path of the rcc executable in your Qt installation.
By default, the script fetches the current Contents file from the server to see which files need to be updated, and generate only those rcc (plus the full rcc files). You can force the script to generate all rcc files by adding the force argument.
By default, the script converts all ogg audio files (to mp3 and aac) to be able to generate full-xxx.rcc files. You can use the skipFullRcc argument to convert only the audio files required to generate the rcc files which need to be updated and skip generating the full-xxx.rcc files.
The force and skipFullRcc arguments are mutually exclusive, use only one at a time.
By default, the audio encoding part runs 4 jobs in parallel, you can increase that depending on the number of core/threads of your CPU (edit the PARALLEL_ENCODING variable at the top of encode_to.sh).
All generated rcc files are stored in scripts/data3/, the same way they are stored on the server.
It takes around 3 GB of disk space to generate all the data.
Starting with GCompris 2.4, we have updated all the png images to webp. To keep compatibility with the older versions, we have created a new words-webp rcc file and kept the words/words folder (with png images). We should not update it anymore and all new updates should be done in the words-webp folder.
