Installation of the flutter framework.

The RAM requirements for Linux.

Studio: 8 GB
Studio & Emulator: 16GB

If you're running 64-bit you need to install some 32-bit libraries.

bzip2
ncurses
zlib

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.

I haven't installed the 32-bit libraries as it's unclear if they're only used for multilib app builds.

Here's how to install Google Chrome on Slackware.

Deps: go1.24.3.windows-amd64.zip

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.
