Hi, I'm having a problem when installing the Riscv-gnu-toolchain on linux 22.04.1.
I'm using:

./configure --prefix=/opt/riscv
make

But, I'm receiving the following error:

checking whether sigaltstack is declared... yes
checking for struct tms... yes
checking for clock_t... yes
checking for F_SETLKW... yes
checking for O_CLOEXEC... yes
checking for AF_UNIX... yes
checking for AF_INET6... yes
checking for _LK_LOCK... no
checking if mkdir takes one argument... no
File "../.././gcc/gcc/config/riscv/arch-canonicalize", line 91

^
SyntaxError: invalid syntax
--with-abi=lp64d is not supported for ISA
make[1]: *** [Makefile:4549: configure-gcc] Erro 1

I don't know why, but I'm using an enviroment with python2.7, and it still doesn't work.

I'm probably missing something on my environment, I just don't know what it is.

Please see the riscv-gnu-toolchain README.

In particular the prerequisites which include Python 3.

You may also need to install python-is-python3.

I installed the prerequisites, but also, I think this script in written in python2.7, since it's using the __future__ package.

running without the python2 env and with python-is-python3 installed, the problem still happens

I don't know why others are having problems.

I did a clean install of WSL2/Ubuntu 22.04.3 and did the following and it all works fine for me:

```

# Install all available updates

sudo apt update

sudo apt upgrade

# Install riscv-gnu-toolchain prerequsites

# https://github.com/riscv-collab/riscv-gnu-toolchain#prerequisites

sudo apt install autoconf automake autotools-dev curl python3 python3-pip libmpc-dev libmpfr-dev libgmp-dev gawk build-essential bison flex texinfo gperf libtool patchutils bc zlib1g-dev libexpat-dev ninja-build git cmake libglib2.0-dev

# https://github.com/riscv-collab/riscv-gnu-toolchain/issues/1251

sudo apt install python-is-python3 expect device-tree-compiler libglib2.0-dev pip

# Clone riscv-gnu-toolchain

cd ~/Downloads

git clone https://github.com/riscv-collab/riscv-gnu-toolchain

cd riscv-gnu-toolchain

# Configure

./configure --prefix=`pwd`/installed-tools --enable-multilib --with-sim=spike

# Build

make

```

I just did exactly what you wrote, and I still have the same problem, unfortunately.

Which Python interpreter does `/usr/bin/env -v python` start, when you
type that in your terminal?
What does `which python` tell?
Is it possible that you have a Python 2 interpreter in /usr/local
which is used when you invoke `python`?

This package is compatible with Python 3:
https://docs.python.org/3/library/__future__.html

Note, that Python 2.x is no longer supported:
https://devguide.python.org/developer-workflow/development-cycle/index.html#end-of-life-branches
Python 2 support ended on January 1, 2020.
The last version of Python 2 was 2.7.18 which was released in April 2020.
GCC does not depend on such outdated software.

I've used the same set of instructions that I outlined on WSL2/Ubuntu 22.04.3 and Zorin OS Lite 16.3 (Ubuntu 20.04 LTS derivative) and they worked fine in both cases.

I think I've also used other distros too.

Thanks for the answer,
"/usr/bin/env -v python" shows python 3.10.12 | packaged by conda-forge
I can uninstall python 2, but it's using python3.10 when invoking python

which python shows > /home/victortoon/mambaforge/bin/python

Just to test I did this on Windows 10:

```

# In Windows PowerShell

# Ensure clean install of Ubuntu on WSL2

wsl --unregister Ubuntu

wsl --install Ubuntu

# In WSL2/Ubuntu command shell

# Update

sudo apt update

sudo apt upgrade

# Install riscv-gnu-tools prerequisites - https://github.com/riscv-collab/riscv-gnu-toolchain#prerequisites

sudo apt install autoconf automake autotools-dev curl python3 python3-pip libmpc-dev libmpfr-dev libgmp-dev gawk build-essential bison flex texinfo gperf libtool patchutils bc zlib1g-dev libexpat-dev ninja-build git cmake libglib2.0-dev

# Clone, configure and build riscv-gnu-toolchain

git clone https://github.com/riscv-collab/riscv-gnu-toolchain

cd riscv-gnu-toolchain

./configure --prefix=$HOME/riscv-tools

date > build.log && make 2>&1 | tee -a build.log && date >> build.log

```

The build completes without any issues.

FWIW I don't see any mention of `arch-canonicalize` in `build.log`.

The same approach worked with a multilib build:

```

./configure --prefix=$HOME/riscv-tools --enable-multilib

```

But if I use `--with-multilib-generator` I get an error:

```

./configure --prefix=$HOME/riscv-tools --with-multilib-generator="rv32gc-ilp32d--"

make

...

checking if mkdir takes one argument... no

/usr/bin/env: 'python': No such file or directory

invalid option for --with-multilib-generator

make[1]: *** [Makefile:4549: configure-gcc] Error 1

make[1]: Leaving directory '/home/user/riscv-gnu-toolchain/build-gcc-newlib-stage1'

make: *** [Makefile:591: stamps/build-gcc-newlib-stage1] Error 2

```

And I have to install `python-is-python3` to proceed.

```

sudo apt install python-is-python3

```

FWIW this is all the python stuff that's installed on my host:

```

sudo apt list --installed | grep -i "python"

I also installed a new Ubuntu 20.04.03 VirtualBox VM using the ISO from here:

* https://releases.ubuntu.com/jammy/

* https://releases.ubuntu.com/jammy/ubuntu-22.04.3-desktop-amd64.iso

I installed the minimal desktop version and then did the following:

```

# Install latest updates

sudo apt update

sudo apt upgrade

# Install riscv-gnu-toolchain prerequisites - https://github.com/riscv-collab/riscv-gnu-toolchain#prerequisites

sudo apt install autoconf automake autotools-dev curl python3 python3-pip libmpc-dev libmpfr-dev libgmp-dev gawk build-essential bison flex texinfo gperf libtool patchutils bc zlib1g-dev libexpat-dev ninja-build git cmake libglib2.0-dev

# Clone, configure, build riscv-gnu-toolchain

git clone https://github.com/riscv-collab/riscv-gnu-toolchain issue-1343

cd issue-1343

./configure --prefix=`pwd`/installed-tools

make

```

And this completed without any issues.

Building in a fresh environment in docker or some VM can be helpful if something in your long used and crufty environment mucks up standard builds that are known to work elsewhere.
