SYMMETRICA-MANUAL -- First steps in a UNIX environment

First steps in a UNIX environment

First steps in a UNIX environment

At first we will describe how to set up SYMMETRICA on a computer with UNIX operating system. This system has a utility called

make

which allows the various actions required in setting up SYMMETRICA to be coded in a special file called

makefile

and to be invoked by a simple command. We will see the details below. (If you don't have UNIX availabe, you can only make use of the files the names of which end with .c. The case when you are in a DOS environment will be discussed in the following section.)

Please look at the files that you find in your directory, and carefully read the following two items that describe how you get started:

Please check first, if there are files ending with .o. If this is so, then you have got a copy of SYMMETRICA that is taken from somebody else's computer, and which already contains object files. Hence it is advisable first to remove these files ending with .o. The corresponding command is
```
rm *.o
```
The next step is to check if there is already a file test.c. In the case when you find such a file, then you continue with the next item. If there is no such file, then please copy one of the example files, say ex1.c into a file with the name test.c. This is done by entering the line
```
cp ex1.c test.c
```
Now you copy the file make.unix into makefile by entering the line
```
cp make.unix makefile
```
Having done this, please enter
```
make
```
and wait until your prompt returns. This will need some time while your machine is busy in translating the .c-files into executable ones.

As soon as the prompt has returned the system is ready to go, and therefore you may now continue reading the next sections of this chapter, in particular the section on the example files, but you may also skip this and continue with the second chapter.
