Using the Meson “sourceset” functionality, The source code is highly modularized, split across many files toįacilitate building of all of these components with as little duplicatedĬompilation as possible. other data files, such as icons or desktop filesĪll executables are built by default, except for some contrib/īinaries that are known to fail to build on some platforms (for exampleģ2-bit or big-endian platforms).ROMs, which can be either installed as binary blobs or compiled.Tools - qemu-img, qemu-nbd, qga (guest agent), etc.The Meson build system is currently used to describe the build Then –static will be automatically added to $ARGS Print $MESSAGE to stderr, followed by $MORE… and then exit from theĬonfigure script with non-zero status query_pkg_config $ARGS.
