GAP 4.11.1

For an overview of changes in GAP 4.11.1 see CHANGES.md file.

Linux and OS X

Download one of the gap-4.11.1.* 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.

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 installer, which contains 64-bit binaries for GAP (compiled with the support of GMP and readline libraries) and for selected GAP packages, and provides the standard installation procedure.

Note that the path to the GAP directory should not contain spaces. For example, you may install GAP in C:\gap-4.11.1 (default), D:\gap-4.11.1 or C:\Math\GAP\gap-4.11.1, but you must not install it in a directory named like C:\Program files\gap-4.11.1 or C:\Users\alice\My Documents\gap-4.11.1 etc.
