GAP 4.12.0

For an overview of changes in GAP 4.12.0 see CHANGES.md file.

Linux and macOS

Download one of the gap-4.12.0.* archives below, unpack it and run ./configure && make in the unpacked directory. Then change to the pkg subdirectory and call ../bin/BuildPackages.sh to run the script which will build most of the packages that require compilation (provided sufficiently many libraries, headers and tools are available). For further details, see here. Expert users can find the description of all installation options in the INSTALL.md file.

gap-4.12.0.zip 502 MB sha256: 42ade38c8d4e99f98feca7f52b3627dd0385c19723d2a6ac582db79bd20644af

You may also consider one of the alternative distributions. Note, however, that these are updated independently and may not yet provide the latest GAP release.

Windows

For users of Windows 10, we strongly recommend using GAP via the Windows Subsystem for Linux.

Otherwise, we recommend the use of the following .exe installers, which contains binaries for GAP (compiled with the support of GMP and readline libraries) and for selected GAP packages, and provides the standard installation procedure. Both 32-bit (x86) and 64-bit (x86_64) versions are available. For almost all users, 64-bit GAP is by far the better choice. Please note that the provision of 32-bit Windows installers is likely to be dropped from GAP releases in the near future.
