The Vector Enumerator (VE) is written in C and the package can only be installed under UNIX. It has been tested on DECstation running Ultrix, a 486 running NetBSD, and SUNs running SunOS.
The parts of the package that deal with rationals require the GNU multiple precision arithmetic library GMP. Make sure that this library is installed before trying to install VE.
If you got a complete binary and source distribution for your machine, nothing has to be done if you want to use the VE for a single architecture. If you want to use the VE for machines with different architectures skip the extraction and compilation part of this section and proceed with the creation of shell scripts described below.
If you got a complete source distribution, skip the extraction part of this section and proceed with the compilation part below.
In the example we will assume that you, as user gap, are installing the
VE package for use by several users on a network of two DECstations,
called bert and tiffy, and a NeXTstation, called bjerun. We assume
that GAP is also installed on these machines following the
instructions given in Installation of GAP for UNIX.
Note that certain parts of the output in the examples should only be taken as rough outline, especially file sizes and file dates are not to be taken literally.
First of all you have to get the file ve.zoo (see Getting GAP). Then
you must locate the GAP directories containing lib/ and doc/, this
is usually gap3r4p0 where 0 is to be be replaced by the patch level.
gap@tiffy:~ > ls -l
drwxr-xr-x 11 gap gap 1024 Nov 8 1991 gap3r4p0
-rw-r--r-- 1 gap gap 106307 Jan 24 15:16 ve.zoo
gap@tiffy:~ > ls -l gap3r4p0
drwxr-xr-x 2 gap gap 3072 Nov 26 11:53 doc

drwxr-xr-x 2 gap gap 2048 Nov 26 09:42 src
drwxr-xr-x 2 gap gap 1024 Nov 26 09:42 tst
Unpack the package using unzoo (see Installation of GAP for UNIX).
Note that you must be in the directory containing gap3r4p0 to unpack
the files. After you have unpacked the source you may remove the
archive-file.
gap@tiffy:~ > unzoo x ve.zoo

Switch into the directory ve/ and type make to see a list of targets
for compilation; then type make target to compile VE, where target
is the target that is closest to your machine. If the header files for
the GNU multiple precision arithmetic are not in /usr/local/include
you must set INCDIRGMP to the correct directory. If the library for
the GNU multiple precision arithmetic is not /usr/local/lib/libgmp.a
you must set LIBDIRGMP. In this case we first compile the
DECstation version.
gap@tiffy:~ > cd gap3r4p0/pkg/ve
gap@tiffy:../ve > make INCDIRGMP=/usr/gnu/include \
LIBDIRGMP=/usr/gnu/lib/ dec-mips-ultrix-gcc2
# you will see a lot of messages
Now repeat the compilation for the NeXTstation. Do not forget to clean up.
gap@tiffy:../ve > mv bin/me.exe bin/me.dec
gap@tiffy:../ve > mv bin/qme.exe bin/qme.dec
gap@tiffy:../ve > rlogin bjerun
gap@bjerun:~ > cd gap3r4p0/pkg/ve
gap@bjerun:../ve > make clean
# you will see some messages
gap@bjerun:../ve > make next-m68k-mach-gcc2
# you will see a lot of messages
gap@bjerun:../ve > mv bin/me.exe bin/me.next
gap@bjerun:../ve > mv bin/qme.exe bin/qme.next
gap@bjerun:../ve > exit
gap@tiffy:../ve >
Switch into the subdirectory bin/ and create scripts which will call
the correct binary for each machine. The shell scripts that are already
contained in `bin/me.sgl` and `bin/qme.sgl` are suitable only for a single
architecture installation.
gap@tiffy:../ve > cat > bin/me
#!/bin/csh
switch ( `hostname` )
case 'bert':
case 'tiffy':
exec $0.dec $* ;
breaksw ;
case 'bjerun':
exec $0.next $* ;
breaksw ;
default:
echo "me/qme/zme: sorry, no executable exists for this machine" ;
breaksw ;
endsw
ctr-D
gap@tiffy:../ve > chmod 755 bin/me
gap@tiffy:../ve > ln bin/me bin/qme
