Installing

Every release carries the pja command for six platforms, each built and tested by CI on that platform:

platform	archive	notes
Linux x86-64	pja-VERSION-linux-x86_64.tar.gz	glibc 2.34 or later
Linux x86 (32-bit)	pja-VERSION-linux-x86.tar.gz	glibc 2.34 or later
Linux arm64	pja-VERSION-linux-arm64.tar.gz	glibc 2.34 or later
macOS arm64 (Apple silicon)	pja-VERSION-macos-arm64.tar.gz	not signed, see below
Windows x64	pja-VERSION-windows-x64.zip	Windows 7 and later
Windows x86 (32-bit)	pja-VERSION-windows-x86.zip	Windows XP and later

Each archive holds pja (pja.exe on Windows), the README, the license, NOTICE and the command's manual (CLI.md). Unpack it and put pja somewhere on your PATH; there is nothing else to install. pja selftest then checks the binary on this processor.

The same release has, for each platform, the zpaq-std plugin (pja-VERSION-zpaqstd-plugin-*, see The zpaq-std plugin) and libpja with the 7-Zip codec (pja-VERSION-lib-*, see Library and 7-Zip).

Checking the download

SHA256SUMS, in the same release, has the checksum of every file:

sha256sum -c --ignore-missing SHA256SUMS      # Linux
shasum -a 256 -c --ignore-missing SHA256SUMS  # macOS

On Windows, Get-FileHash pja-VERSION-windows-x64.zip in PowerShell (or certutil -hashfile FILE SHA256 in cmd) and compare by eye.

macOS

The binaries are not signed, so Gatekeeper stops the first run. After unpacking:

xattr -d com.apple.quarantine pja

Other platforms

Anything FreePascal 3.2 targets should build; see Building. The streams are the same bytes on every platform: a .pja made on one opens on any other.
