The <code>-I</code> option tells <tt>download_and_compile.sh</tt> to ignore inter-component dependencies ( | The <code>-I</code> option tells <tt>download_and_compile.sh</tt> to ignore inter-component dependencies. If you don't use it, other components may be processed too due to these dependencies. The purpose of the behaviour without <code>-I</code> is to help people who aren't necessarily aware of new requirements as time goes (e.g., SIMGEAR and FGFS started to require CARES by the end of 2024; a FlightGear fork of OSG is also required for FGFS ''next'' in 2025). However, it may be frustrating to specify a list of components and see additional ones being automatically added, hence the option. | ||
The <code>-j$(nproc)</code> option is not necessary, but is likely to save you a lot of time; with it, all available CPU cores will be used when compiling—see [[#Multicore acceleration| Multicore acceleration]]. | |||
