Хочется собрать rust из git'а, но это занимает приличное количество времени (емнип, больше часа). Как я понимаю, он собирает вместе с rustc и llvm. Можно ли его не собирать?
Как вообще можно ускорить сборку? Есть ли смысл собирать в RAM и как это сделать?
P.S. Вот список опций для configure:
Options:
--enable-valgrind run tests with valgrind (memcheck by default)
--enable-helgrind run tests with helgrind instead of memcheck
--disable-valgrind-rpass don't run rpass-valgrind tests with valgrind
--disable-docs don't build documentation
--disable-optimize don't build optimized rust code
--disable-optimize-cxx don't build optimized C++ code
--disable-optimize-llvm don't build optimized LLVM
--disable-optimize-tests don't build tests with optimizations
--disable-libcpp don't build with llvm with libc++ instead of libstdc++ when using clang
--disable-llvm-assertions don't build LLVM with assertions
--disable-debug don't build with extra debug fun
--enable-ratchet-bench ratchet benchmarks
--enable-fast-make use .gitmodules as timestamp for submodule deps
--enable-ccache invoke gcc/clang via ccache to reuse object files between builds
--enable-local-rust use an installed rustc rather than downloading a snapshot
--enable-llvm-static-stdcpp statically link to libstdc++ for LLVM
--enable-rpath build rpaths into rustc itself
--enable-nightly build nightly packages
--disable-verify-install don't verify installed binaries work
--enable-dist-host-only only install bins for the host architecture
--disable-inject-std-version don't inject the current compiler version of libstd into programs
--disable-jemalloc don't build liballoc with jemalloc
--localstatedir=[/var/lib] local state directory
--sysconfdir=[/etc] install system configuration files
--datadir=[/share] install data
--infodir=[/share/info] install additional info
--llvm-root=[<none>] set LLVM root
--jemalloc-root=[<none>] set directory where libjemalloc_pic.a is located
--build=[x86_64-unknown-linux-gnu] GNUs ./configure syntax LLVM build triple
--android-cross-path=[/opt/ndk_standalone] Android NDK standalone path
--disable-manage-submodules don't let the build manage the git submodules
--enable-clang prefer clang to gcc for building the runtime
--prefix=[/usr/local] set installation prefix
--local-rust-root=[/usr/local] set prefix for local rust binary
--host=[<none>] GNUs ./configure syntax LLVM host triples
--target=[<none>] GNUs ./configure syntax LLVM target triples
--mandir=[/share/man] install man pages in PATH
--release-channel=[dev] the name of the release channel to build
configure: CFG_BUILD :=
--libdir=[/lib] install libraries (do not set it on windows platform)
P.P.S. Есть ли смысл ставить бинарный rustc из реп арча и указывать его как local?
