These instructions refer to the standalone use of the package.
See the file README_GAP and the section in the GAP manual for use with GAP.
Full documentation for this package is contained in the files in 'doc'.
The sources of all 'C' programs and makefile are contained in 'src'.
To compile everything go into 'src' and type
make all
The default C compiler is gcc, and the default compiler option is -O2.
To change these, type, for example:
make CC=cc CFLAGS=-g all
You can tidyup by typing
make clean
The executable binaries are put into 'bin'. Some Bourne shell programs (in
particular, 'cohomology') are also in 'bin' (but have copies in 'src').
The user's path should therefore contain the directory 'bin'.
Computations are usually carried out from within 'data', which
contains all data files for groups.
The cohomology programs would run into problems with
primes >=100, although the 'testmf' program (which does elementary matrix ops
modulo an integer) should work with bigger moduli.
Please let me know of any error found as soon as possible.

To install this package for using with GAP, simply type make The default C compiler is gcc, and the default compiler option is -O2. To change these, type, for example: make CC=cc CFLAGS=-g You can tidyup by typing make clean The executable programs are put into a directory in the directory 'bin', with name equal to the hostname of the machine. The GAP interface files are 'init.g' and the files in the directory 'gap'. To exercise the interface and the external programs, go into the directory 'gap', call GAP and type ReadTest( "cohomolo.tst" ); The GAP prompt should appear after some time, without any messages. When you run GAP and wish to use the cohomology functions, call RequirePackage( "cohomolo" ); Documentation (in the form of a GAP manual chapter) is in the directory 'gapdoc'. To printout this chapter, go into this directory and type latex manual which will produce the dvi-file for this chapter as manual.dvi. Some example files to play with are in the directory 'gapdata'. Please let me know of any problems. Derek Holt (dfh@maths.warwick.ac.uk)
