Building upstream RISC-V GCC+binutils+newlib: the quick and dirty way
September 5, 2017

There are a number of available options for building a RISC-V GCC toolchain. You might use the build system from the riscv/riscv-tools repository, or investigate toolchain generators such as crosstool-ng. However in the case of riscv-tools, it’s not always clear how this corresponds to the code in the relevant upstream projects. When investigating a potential bug, you often just want to build the latest upstream code with as little fuss as possible. For distribution purposes you’d probably want to perform a proper multi-stage build, but for a quick test you might find the following recipe useful:

git clone --depth=1 git://gcc.gnu.org/git/gcc.git gcc
git clone --depth=1 git://sourceware.org/git/binutils-gdb.git
git clone --depth=1 git://sourceware.org/git/newlib-cygwin.git

cd combined
