- Ptolemy Installation:
- --------------------
-
- Ptolemy is a large software system that relies on a properly
- configured software environment. There are many things that can
- go wrong in getting Ptolemy running. For instance, the windowing
- system may not be the same one we use, or it may be used in a
- different way. There is also some configuration required by each
- user in order to use the graphical interface. The information
- for doing this is given in the Pigi document, section 2 of the
- Almagest. Here we give the basic information required to get
- from an FTP archive or distribution tape to being able to run the
- system.
-
-
- 1.1 Basic Ptolemy Installation
-
- First note that the approximate disk space requirements are
- (for the Sun-4 distribution; other distributions are roughly the
- same size):
-
- Ptolemy: 49 Mbytes
- Ptolemy (after you optionally remake): 64 Mbytes
- Gnu subset: 16 Mbytes
-
- Create a user "ptolemy" together with a home directory
- for the "ptolemy" user. Once the "ptolemy" user account has
- been created, log in or su to user "ptolemy" If you do not
- wish to create a user called "ptolemy" see below for an alter-
- native.
-
- If you are loading Ptolemy from a tape, do the following:
-
- a. cd /tmp (or any directory where you have write permission
- and there is at least 30 Mbytes of free disk space). (If you
- do not have this amount free, you can extract the four files
- one at a time. See the tar man page for details, or ask your
- system administrator)
-
- b. Load the tape into your drive
-
- c. mt -f /dev/nrst8 rewind
- (This rewinds the tape -- change the device name if your
- tape drive has a different name.)
-
- d. tar xf /dev/nrst8
-
- If you have used FTP to down load the files, then cd to the
- directory that contains the "*tar.Z" files you downloaded via
- FTP.
-
- Now, whether you've used tape or FTP, there should be a number of
- large "*tar.Z" files in your current directory. Proceed as fol-
- lows:
-
- 1. zcat pt-0.4.1.doc.tar.Z | ( chdir ~ptolemy/..; tar xf - )
- (this uncompresses the documentation, changes directory the
- parent of the "ptolemy" user, and then creates all of the
- documentation files.)
-
- 2. zcat pt-0.4.1.src.tar.Z | ( chdir ~ptolemy/..; tar xf - )
- (this uncompresses the src and creates the source files.)
- You must not skip this step. Ptolemy depends on these files
- being present. Note that you may get a few warning messages
- during this and the following step about the tar program not
- being able to create some directories because they already
- exist. This is expected (the same directory is mentioned in
- several of the tar files), so you need not worry.
-
- 3. If you are running the DecStation (MIPS) version of Ptolemy:
- zcat pt-0.4.1.mips.tar.Z | ( chdir ~ptolemy/..; tar xf - )
- If you are running the Sun 4 (Sparc, IPC, IPX, etc) version:
- zcat pt-0.4.1.sun4.tar.Z | ( chdir ~ptolemy/..; tar xf - )
- If you are running the HP (hppa) version:
- zcat pt-0.4.1.hppa.tar.Z | ( chdir ~ptolemy/..; tar xf - )
- (this uncompresses the binaries and creates the executable
- files.) Note that is possible to install both the Sun-4 and
- the DecStation binaries on the same file system as different
- directories are used for each set of binaries.
-
- 4. You no longer need the pt-0.4.1.xxx.tar.Z files that you got
- from the FTP site or the tape. Remember to delete these
- files to free up storage space.
-
- 5. cd ~ptolemy
- (change directories to the ptolemy root directory)
-
- 6. Edit ~ptolemy/.rhosts, adding a line for your system (This
- gives pigi permission to create an RPC server process with
- the rsh command ). The added line will be of the form
- "hostname ptolemy", you can find the correct hostname with
- the Unix command "hostname". Users will also need entries
- in their .rhosts files to allow the server process to start
- up.
-
- 1.2 Installation with out creating a "ptolemy" user
-
- The preferred installation technique, as indicated above, is
- to create a user called "ptolemy" The reason for this is that
- running Ptolemy requires an appropriate user configuration. At
- minimum, the user's path must be set up properly. The
- "ptolemy" user is also configured to run an X window manager
- (twm) with suitable X resources that are known to work. In
- troubleshooting an installation, having the "ptolemy" user
- properly configured can be very valuable.
-
- However, we recognize the some sites resist the creation of
- fictitious users. Consequently, Ptolemy can be installed any-
- where. If you do this, every Ptolemy user must set a PTOLEMY
- environment variable to point to the root directory of Ptolemy.
- The installation is the same as above, except that "~ptolemy"
- is replaced with "$PTOLEMY"
-
- 1.3. Special considerations for installation under Open Windows
-
- Ptolemy was developed using the X11R4 or X11R5 distributions
- from MIT. It will run successfully under Open Windows version 2.
- There are problems with running the graphic interface with Open
- Windows version 3, however. Some users have had no problems at
- all, but others have had intermittent problems such as "bad
- match" errors. We believe this may be a problem with the X-
- server supplied with the Open Windows 3.0, but the error is
- elusive and we have not yet tracked it down.
-
- In order for all utilities included with this distribution
- to work under Open Windows (either version), you must install the
- shared libraries for the Athena widgets (the freely redistribut-
- able widget set from the MIT X11 distribution), which are pro-
- vided with this distribution under the "~ptolemy/athena.sun4"
- directory. To install them, become root and copy all files in
- that directory into "/usr/openwin/lib" (or, if you have
- installed Open Windows in a non-standard place, into
- "$OPENWINHOME/lib"). If you do not wish to do this, you could
- leave them in place and have every Ptolemy user change their
- LD_LIBRARY_PATH environment variable to search
- "~ptolemy/athena.sun4" before "/usr/openwin/lib." Consult
- the Unix manual entry for the "ld" program to learn more about
- this.
-
- After installation, the ptolemy account will contain several
- scripts for starting up X11R5 (Xrun), Open Windows with olwm
- (Xrun.ow), or Open Windows with twm (Xrun.ow.twm).
-
- 1.4 GNU Installation
-
- For convenience, some software from the Free Software Foun-
- dation is included on the distribution tape. This includes the
- compiler used to make Ptolemy, which is also the compiler you
- will use to extend Ptolemy. Note that this is not a complete set
- of Gnu software.
-
- To install the ptolemy gnu subset, proceed as follows:
-
- 1. cd /usr/tools
-
- 2. Check to see if there is already a "gnu" directory. If so,
- you probably don't want to load the ptoelmy gnu files here
- and should pick a different location for the ptolemy gnu
- subset (be especially careful in step 6 below). If there is
- not already a "gnu" directory, then do the following command:
- mkdir gnu
-
- 3. If you have Ptolemy on tape, then cd to the directory you
- used to download the files from the tape in the "Basic
- Ptolemy installation" steps above.
-
- 4. If you have used FTP to get the ptolemy gnu file, then cd to
- the directory that contains the files you downloaded via FTP.
-
- 5. You should now have a gnu-xxx.tar.Z file (where xxx is an
- architecture supported by ptolemy such as "sun4", "hppa", or
- "mips") in your current directory.
-
- 6. Note, if they was already a "gnu" directory in "/usr/tools"
- (see step (2) above) you will need to change the commands
- below. Replace "/usr/tools" with the name of the parent
- directory of the location you have picked for the ptolemy
- gnu subset.
-
- If you are running on a Sun 4 (Sparc, IPC, IPX, etc) then:
- zcat gnu-sun4.tar.Z | ( chdir /usr/tools; tar xf - )
- If you are running on a DecStation (MIPS) then:
- zcat gnu-mips.tar.Z | ( chdir /usr/tools; tar xf - )
- If you are running on a DecStation (MIPS) then:
- zcat gnu-hppa.tar.Z | ( chdir /usr/tools; tar xf - )
-
- 7. You no longer need the gnu-xxx.tar.Z file that you got from
- the FTP site or the tape. Remember to delete this file to
- free up storage space.
-
- The gnu tar files also contain the gnu source code in the
- /usr/tools/gnu/src directory. You will save disk space and
- Ptolemy will still run fine if you delete all of the gnu source
- files. However, if you plan to redistribute the tools (give them
- to anyone else) you must include sources, according to the Gnu
- Public License. Therefore, it may be a good idea to keep these
- source files around.
-
- It is also possible to build Ptolemy with Sun's port of AT&T's
- cfront compiler, version 2.1. To do so, you must completely re-
- build Ptolemy. The libraries on the tape were produced by the
- Gnu C++ compiler and are not interoperable with cfront code.
-
- 1.5 Testing the installation
-
- 7. You no longer need the gnu-xxx.tar.Z file that you got from
- the FTP site or the tape. Remember to delete this file to
- free up storage space.
-

- /usr/tools/gnu/src directory. You will save disk space and

- files. However, if you plan to redistribute the tools (give them
- to anyone else) you must include sources, according to the Gnu

- build Ptolemy. The libraries on the tape were produced by the
- Gnu C++ compiler and are not interoperable with cfront code.
-
- 1.5 Testing the installation
-
- Note that the following tests assume that you have created a
- user "ptolemy" and installed the system there. One advantage of
- such an installation, is that the user "ptolemy" already has a
- working .cshrc and .login file to make startup easier.
-
- To test Ptolemy:
-
- 1. login as ptolemy
-
- 2. If the X server is not already running, the .login script
- will attempt to start it. If your installation is different
- from ours, you may need to modify .login to work at your
- site (in particular, you may need a different path vari-
- able).
-
- 3. cd demo
-
- 4. pigi
-
- 5. Follow instructions in section 2 of the Almagest titled,
- "Running the Ptolemy Demos" (section 2.3.1).
-
- Note that the ptolemy user provides a model of a user prop-
- erly configured to run ptolemy. All the .files in the home
- directory are set up according to the tastes of the Ptolemy
- authors, and according the standard use of windowing software in
- the Ptolemy development group.
-
- 1.6 Rebuilding Ptolemy from Source
-
- If you wish to rebuild Ptolemy from source (this step is
- recommended if you plan to do major development work, such as
- adding a new domain), it is simply a matter of editing the
- appropriate configuration file and typing "make" This is
- explained in a bit more detail below.
-
- Configuration files live in the root directory of your
- ptolemy system. If you have installed PT as the user "ptolemy"
- then these file are in the ~ptolemy home directory. The confi-
- guration file are all named "config-xxx.mk" where the "xxx"
- is something like "sun4" for a Sun-4 system or "mips" for a DecS-
- tation. They are included by other makefiles and define symbols
- specifying compiler flags, the directory where X include files
- are located, etc. The file that is used is determined by replac-
- ing "xxx" above by the value of the ARCH environment variable.
-
- If you wish to rebuild using cfront rather than g++, use
- config-cfront.mk as a starting point to produce your configura-
- tion file. This has been tested with cfront 2.1 on a Sun-4; for
- other platforms, you may need to do some tweaking.
-
- To rebuild the system, first adjust the configuration param-
- eters in the appropriate configuration file. For example, if you
- are using the Gnu tools on a Sun-4, then you will need to adjust
- the "config-sun4.mk" file.
-
- Next, run make. We recommend using Gnu make, which is
- included in the gnu subset. (Make sure that the Gnu tools are
- installed correctly.) Ultrix make will definitely not work.
-
- You will get some warnings from the compiler, but the fol-
- lowing warnings can safely be ignored:
- any warning about file_id' defined but not used.
- ../../src/kernel/Tokenizer.cc:85: warning: cast discards `const'
- from pointer target type
- ../../../../src/domains/thor/kernel/fprval.cc:56: warning:
- ordered comparison between signed and unsigned
- ../../src/ptcl/PTcl.cc:<n>: warning: cast discards `const' from
- pointer target type (this warning may appear four times with dif-
- ferent values of <n>)
- ../../src/ptcl/ptclMain.cc:75: warning: unused variable `ptcl'
