Here are the system requirements for Linux:

Requirement    Minimum                           Recommended
RAM            Studio: 8 GB                      32 GB RAM or more
               Studio & Emulator: 16GB

Required libraries for 64-bit machines

If you are running a 64-bit version of Ubuntu, you need to install some 32-bit
libraries with the following command:

sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386 lib32z1 libbz2-1.0:i386

If you are running 64-bit Fedora, the command is:

sudo yum install zlib.i686 ncurses-libs.i686 bzip2-libs.i686
bash-5.1$ grep MemTotal /proc/meminfo
MemTotal: 3913176 kB
bash-5.1$ free -h | awk -v OFS='\t' 'NR==3{print $1, $2}'
Swap:   8.0Gi
bash-5.1$

The hardware limitations do not allocate for installing the emulator.

bash-5.1$ sed -n '6,19p' /var/lib/sbopkg/SBo/15.0/system/wine/README.MULTILIB
https://docs.slackware.com/slackware:multilib

A script that rsyncs with alienBOB's repo and installs the multilib
packages which can be found here:
https://slackware.uk/~dive/scripts/alien-multilib-rsync.sh

Be sure to read the short instructions at the top. If you use slackpkg
then you will also want to blacklist his packages in
/etc/slackpkg/blacklist:

[0-9]+alien
[0-9]+compat32
bash-5.1$ w3m -dump http://www.slackware.com/~alien/multilib/README | sed -n '186,190p'
Slackware 15.0 is the last release that needs separate (alien's) multilib
versions of gcc and glibc.
On August 30, 2024, Pat Volkerding added multilib capability to Slackware's
own gcc and glibc packages. What you still need to add to your system is
the collection of -compat32 packages.
bash-5.1$

https://gcc.gnu.org/install/configure.html

The multilib (alien's) gcc will pass the --hash-style=gnu option to the linker for all final links.

The slackware-current gcc is not configured with the option --with-linker-hash-style=choice.

rsync over TLS

rsync does by itself not support TLS, but we can simply outsource TLS handling
to the openssl s_client. The rsync authors have made a short script to do
exactly that. This is how you use it to get a listing from our server:

wget https://download.samba.org/pub/rsync/openssl-rsync
chmod +x openssl-rsync
rsync --rsh=./openssl-rsync rsync://mirrors.dotsrc.org

It is wise to read the script before executing it blindly.

Y. Caseau's claire uses Go as its target language.

https://go.dev/doc/install

This is beta as of January 3, 2025.

Use a system installed Go.

In PowerShell from $home run these commands after cloning the repository.

    •  New-Item -ItemType Directory -Name "go"
    •  Move-Item CLAIRE4\init.cl go
    •  Move-Item CLAIRE4\src go
    •  Set-Location go
    •  $env:GO111MODULE = "off"
    •  go build src\claire4.go

You should then have a claire4.exe file in the current directory.
