Overview PARI/GP is a fast computer‑algebra system widely used for number theory, algebra, and high‑precision arithmetic. This guide describes how to compile PARI/GP on piCore64 and package it into a proper TinyCore .tcz extension for persistent use.
The steps below were tested on piCore64 16.x running on Raspberry Pi hardware.
Requirements Load the required development tools and libraries:
tce-load -wi compiletc perl5 gmp-dev readline-dev ncurses-dev squashfs-tools
These provide the compiler, GMP support, readline, and the SquashFS utilities needed to build .tcz extensions.
Download and Unpack PARI/GP mkdir -p ~/src cd ~/src wget https://pari.math.u-bordeaux.fr/pub/pari/unix/pari-2.17.3.tar.gz tar xvf pari-2.17.3.tar.gz cd pari-2.17.3
Configure the Build Configure PARI/GP to install into /usr/local and use GMP and readline:
./Configure –prefix=/usr/local –with-gmp –with-readline
Compile and Install make -j4 sudo make install
This installs:
/usr/local/bin/gp /usr/local/lib/pari/ /usr/local/share/pari/ Create the .tcz Staging Directory mkdir -p ~/tcz/pari-gp/usr/local
Copy the installed files into the staging area:
cp -rf /usr/local/bin ~/tcz/pari-gp/usr/local/ cp -rf /usr/local/lib ~/tcz/pari-gp/usr/local/ cp -rf /usr/local/share ~/tcz/pari-gp/usr/local/
Strip Binaries (Optional) strip ~/tcz/pari-gp/usr/local/bin/gp
This reduces the final extension size.
Build the .tcz Extension cd ~/tcz mksquashfs pari-gp pari-gp.tcz -noappend md5sum pari-gp.tcz > pari-gp.tcz.md5.txt
You should now have:
pari-gp.tcz pari-gp.tcz.md5.txt
Install the Extension into TinyCore Move the files into the extension directory:
sudo mv pari-gp.tcz /etc/sysconfig/tcedir/optional/ sudo mv pari-gp.tcz.md5.txt /etc/sysconfig/tcedir/optional/
Add it to the boot list:
echo “pari-gp.tcz” | sudo tee -a /etc/sysconfig/tcedir/onboot.lst
Reboot and Test sudo reboot gp
You should see the PARI/GP banner and be able to run commands normally.
Notes This extension is self‑contained and does not require persistence via filetool.sh. If you want to include documentation or examples, place them under usr/local/share/pari/ before building the .tcz. The same method works for other mathematical tools such as GMP‑based calculators or Rust‑compiled number‑theory utilities.
