GAP 4.8.10

For an overview of changes in GAP 4.8.10 see CHANGES.md file.

Linux and OS X

Download one of the 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

We strongly recommend to use the .exe installer 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. 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.

The .exe installer should work for the majority of users. Alternatively (for example, if you don't have administrator's privileges on your Windows computer), you may use the -win.zip archive and edit .bat files manually following instructions from the INSTALL.md file. Furthermore, in case of technical problems with readline support under Windows (e.g. command line editing doesn't work, or GAP crashes at startup), we recommend to try the -noreadline-win.zip archive.

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