usage: ./build.sh [-x] [-a nt32|nt64] [-b debug|release] [-c] [-C] [-h] [-n] [-N] [-r package[,...][:step]] [-t[.gz|.bz2|.xz] [-v] [[ ...]] -x Set the xtrace sh(1)ell option for debugging purposes. -a nt32|nt64 Selects 32-bit or 64-bit architecture; defaults to nt64. -b debug|release Selects debug or release build; defaults to debug. This currently only controls CFLAGS. -c Clean ${PREFIX} before processing build scripts. -C Check package(s) for updates upstream. -h Show this screen. -n Perform dry run. -N Offline mode: no {wget,git-{clone,pull}}(1) calls. -r package[,...][:step] Restart the specified comma-separated build(s) completely or at the optionally specified step. Currently defined steps are: fetch extract build_dir patch_pre autoconf patch configure clean build install. -t[.gz|.bz2|.xz] Produce binary distribution and source tarballs containing ${PREFIX} sans ${WORKDIR} and ${PREFIX}/src/midipix_build and ${WORKDIR} sans top- level regular files at the end of a build with zero failures. The tarballs will be compressed with either gzip, bzip2, or xz and signed with GPG; the default compression is xz. -v Be verbose; this currently only affects secure_{cd,rm}() and insecure_mkdir(). [ ...] One of: host_toolchain, native_toolchain, runtime, lib_packages, leaf_packages, world, or devroot. ${HOME}/midipix_build.vars, ../midipix_build.vars, and build.vars are sourced if they exist. Packages that are built by pkg.build will apply local patches in ${WORKDIR} named ${PKG_SUBDIR}.local.patch. Examples: ./build.sh -r coreutils Completely restart the coreutils build. ./build.sh -r coreutils:configure,build,install Restart the configure, build, and install steps of the coreutils build. ./build.sh -r psxscl GITROOT_HEAD=... PKG_PSXSCL_CFLAGS_CONFIGURE_EXTRA=-DPSX_INTERNAL_STRACE Build psxscl from the internal repository with strace enabled. ./build.sh -c -r ALL GITROOT_HEAD=... Clean ${PREFIX} and forcibly rebuild everything.
