buildcross - a tool for building GCC cross toolchains
Usage:
buildcross [options] [<TARGET>] [<CROSS_DIR>]
Options:
--cross-dir=<CROSS_DIR> | -c <CROSS_DIR>
Place resulting cross-compiler in <CROSS_DIR>.
Default: <CWD>/cross-<TARGET>
--downloads-dir=<DOWNLOADS_DIR> | -d <DOWNLOADS_DIR>
Place downloaded sources in <DOWNLOADS_DIR>.
Default: <CWD>/downloads
--host-tools-dir=<HOST_TOOLS_DIR> | -h <HOST_TOOLS_DIR>
Place built host tools in <HOST_TOOLS_DIR>.
Default: <CWD>/host-tools
-j<N>
Pass -j<N> to make. Default: empty
--sources-dir=<SOURCES_DIR> | -s <SOURCES_DIR>
Place unpacked source archives in <SOURCES_DIR>.
Default: <CWD>/sources
--target=<TARGET> | -t <TARGET>
Build the indicated <TARGET>. If this option is
not present then <TARGET> must be present as the
first non-option parameter.
