If your linux distro is based on debian, e.g. ububtu, linux mint etc... download this script: https://sourceforge.net/projects/skylendar/files/installskylendar.sh then, execute the folling command in your terminal: bash installskylendar.sh Press y when asked if you want to download the archive. If not debian, you have to compile and install skylendar yourself, unless you find out someone else who can help you. Try in the forums of your distro. If something goes wrong, run bash installskylendar.sh -d and report to me. Important note about the "extra time" bug: the workaround of this bug needed the "extra time" set to 1.00. It seems to be a gcc problem and also can be found on the previous versions of clang. However, on clang-20, the bug seems to be fixed, that's why I posted on sourceforge the tar archive of skylendar compiled with clang-20. Don't forget to set the extra time to 0.0 skylendar@yahoo.com
