In order to cross compile the libraries or applications for Raspberry Pi5 on the computers with different architecture we need a cross-compiler toolchain (gcc, libc, binutils and so on). However, it is not enough if you are building, for example, an application which requires the third-party libraries. In such a case we have to provide gcc with a directory (–sysroot=dir option) that works as a root for headers and libraries of the Raspberry Pi 5 root file system.
