GAP 4.8.3

For an overview of changes in GAP 4.8.3 see CHANGES.md file.

Linux and macOS

Download one of the archives below, unpack it and run ./configure; make in the unpacked directory. Then put and run in the pkg subdirectory the shell script InstPackages.sh (for 32-bit builds on 64-bit machines, use InstPackages32.sh) in order to build most of the packages that require compilation provided sufficiently many libraries, headers and tools are available (you may have to run chmode first). For further details, see here. Expert users can find the desciption 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

We strongly recommend to use the .exe installer which contains binaries for GAP and some packages and provides the standard installation procedure. Note that the path to the GAP directory should not contain spaces. For example, you may install it in C:\gap4r8 (default), D:\gap4r8p3 or C:\Math\GAP\gap4r8, but you must not install it in a directory named like C:\Program files\gap4r8 or C:\Users\alice\My Documents\gap4r8 etc.

Alternatively, you may use the -win.zip archive and edit .bat files manually following instructions from the INSTALL.md file. In case of technical problems with readline support under Windows, try the -noreadline-win.zip archive.

In addition, there is an experimental 64-bit version of GAP for Windows here:
