usage: ./build.sh [-c] [-nd] [-r ALL|name[:step]] [-h] [-t] -c Clean $PREFIX before processing build scripts. -nd Don't rm(1) and re-download tarballs when not required. -h Show this screen. -pt Enable pedantic mode. In addition to the warnings emitted whenever a potentially dangerous operation is invoked by the build scripts, manual confirmation will be required. This currently only includes rm_if_exists(). -r ALL|name[:step] Restart all or the specified build script(s) completely or at the optionally specified build step. Currently defined build steps are: fetch extract patch configure clean build install configure1 configure2 build1 build2 install1 install2. -t Produce a distribution tarball containing $PREFIX sans $WORKDIR and $PREFIX/src/midipix_build at the end of a build with zero failures. -x Set the xtrace sh(1)ell option for debugging purposes. -X Set the xtrace sh(1)ell option and compile a tarball containing build.log and $PKG_SUBDIR. Use this option if something goes wrong and provide an URL to the tarball in . Packages that are built by pkg.build will apply local patches in $WORKDIR named ${PKG_SUBDIR}.local.patch. Examples: ./build.sh -r ALL Forcibly restart the entire build. ./build.sh -r 301.coreutils.build Completely restart the coreutils build. ./build.sh -r 301.coreutils.build:configure,build,install Restart the configure, build, and install steps of the coreutils build script. ./build.sh -r 205.psxscl.build 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.
