Error when building riscv-gnu-toolchain

[mahsoom...@gmail.com]

I cloned the toolchain repository and also ran submodule update --init --recursive. When I ran the make command. I got an error saying configure file was not found in binutils. I checked the folder and found that the binutils folder was empty. I ran submodule update again with the same result.

I then went to the GitHub page and found the submodule was blacked out and that I cannot open the submodule. Any idea what's happening here?

It's always a good idea to tell what your environment is and copy and
paste *exactly* the commands you ran (not their output, except
errors), rather than a vague description, so that people can attempt
to duplicate the problem -- or spot an obvious mistake.

These things do usually work. If it doesn't it's most likely your mistake.

Did you check you have the necessary prerequisites installed? e.g.

autoconf automake autotools-dev curl libmpc-dev libmpfr-dev libgmp-dev
gawk build-essential bison flex texinfo gperf libtool patchutils bc
zlib1g-dev libexpat-dev

I just ran exactly these commands and it worked fine on Ubuntu 16.04.3 LTS.

git clone --recursive https://github.com/riscv/riscv-gnu-toolchain
mkdir install
cd riscv-gnu-toolchain
./configure --prefix=`pwd`/../install
make

Note that the install directory must be writable, as there is no
separate "make install" step.

You don't say which tools you're trying to build, bare metal/newlib or Linux, but if it's the former then why not use crosstool-NG or Liviu's GNU MCU Eclipse build scripts as they "just work" even for Canadian cross (build on Linux to run on Windows to target RISC-V)? CT-NG should be able to also build the Linux toolchain but I haven't tried that yet myself.

Ignore that. It is a problem with the github web site, and not
relevant to your problem.
