Installing the toolchain

[Aaronyap2002]

Hello, I downloaded and extracted the toolchain version gcc-rv32imc-20210412-1, but I weren't able to install it. What did I do wrong here?

aaron@aaron-TravelMate-P238-M:~/Downloads/lowrisc-toolchain-gcc-rv32imc-20210412-1$ sudo ./configure --prefix=/home/aaron/new1/ --with-arch=rv32gc --with-abi=ilp32d--disable-float--disable-atomic

Hi, if you downloaded the toolchain tarball through GitHub releases, you should get the pre-built binaries, data files, libraries etc. so there's no need to configure or make anything.

You'll need to copy those files somewhere that's in your PATH and library lookup directories.

As an example, this command will extract the tarball into your ~/.local/bin, ~/.local/lib etc. directories:

tar -xf lowrisc-toolchain-gcc-rv32imc-20210412-1.tar.xz --strip-components=1 -C ~/.local

If ~/.local/bin/ is in your PATH, then you should be able to run riscv32-unknown-elf-gcc etc.
