Built GTK based IDE: make -j1 FPC=/usr/bin/fpc LCL_PLATFORM=gtk3 bigide Now proceed to the installation (meaning skip the QT build below). Built Qt6 based IDE: make -j1 FPC=/usr/bin/fpc LCL_PLATFORM=qt6 bigide Likewise, a gtk2 or a qt5 variant can be built in similar way - just use LCL_PLATFORM=gtk2 resp. LCL_PLATFORM=qt5 in the make ... bigide command. It is not included here as gtk2 and qt5 are outdated and no longer included in the BLFS book. This package does not come with a test suite.
