GAP 4.7.7

This release replaces GAP 4.7.6 (see the overview of changes between GAP 4.7.6 and GAP 4.7.7 here).

Linux and OS X

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 (for 32-bit builds on 64-bit machines, use 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 file.

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


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:\gap4r7 (default), D:\gap4r7p6 or C:\Math\GAP\gap4r7, but you must not install it in a directory named like C:\Program files\gap4r7 or C:\Users\alice\My Documents\gap4r7 etc.

Alternatively, you may use the archive and edit .bat files manually following instructions from the INSTALL file. In case of techinical problems with readline support under Windows, try the archive. 358 MB md5: a674c279541d7326f92a4dd108283a75 358 MB md5: 5cf4c6cd14e6fbd7533e07bd6b69f3b9
