Compiling Log

This document assumes that you have successfully compiled the Psys libraries. This document also assumes that you have uncompressed and untarred the Log file, and installed it in the chipmunk directory.

Begin by descending to the log/src directory. At this point OS/2 users only should execute the following commands.

cp Makefile.os2 Makefile

cp ana/Makefile.os2 ana/Makefile

All users should now edit the files Makefile and ana/Makefile, and make any necessary changes. Comments in the Makefile will guide you through these changes; the changes are labeled with the markers (1), (2), (3), ect.

Once these edits are made, check to see if your platform is listed below. If it is, execute the command under the platform name in the log/src directory.

Apple Macintosh, AU/X

cp munch.coff munch

HP Series 700, HPUX

cp munch.hp800 munch

IBM RS/6000

cp munch.rs6000 munch

Sun SPARC, Solaris 2.X (SunOS 5.X)

cp munch.solaris2 munch

Once these changes are made, execute the command

make install

If things are working correctly, a long series of compilations, linkings, and file movements should occur without error. This will create the programs chipmunk/bin/diglog, chipmunk/bin/analog, and chipmunk/bin/loged. To check basic functionality, try to run these three programs. For each program, two windows should appear on program launch, one called newcrt and one called mylib. Type :exit in the newcrt window to leave analog and diglog. Type exit in the newcrt to leave loged. See the user documentation for information on using these tools.

Problems and Solutions

Its quite possible that compilation did not proceed smoothly, or that execution problems happen while using the tool. Here are some possible ways that things could have went wrong, along with suggestions.

File system problems

The symptom is that Log runs fine for a few days (weeks, months), but one day it stops working. Another symptom is that Log runs on the machine it was compiled on, but not on other machines in a NFS cluster. The cause of these problems often traces to Log noting where its absolute location is during compile time, using pwd commands in its Makefiles. If your disk is reorganized, Log will be confused, and recompilation (Psys and Log) will be necessary. Also, if your system uses the NFS automounter, the results of the pwd command may not be correct for every machine on your cluster, or may change with time. In this case, replacing the pwd commands in the log Makefiles with hard-coded paths, or with the environment variable PWD, is a good idea.

log.c won't compile

This file breaks many compilers because of its length, in many different ways. Possible solutions include compiling with or without optimization on, and directing the compiler to place temporary files in a disk partition with more free space.

Print spooling is broken

Pressing File in the Log preview screens should send a Postscript file to a local printer, by writing a file to /tmp, and printing the file using lpr. This may be incorrect for your system. If so, change line 2868 (Unix) or 2865 (OS/2) of the file log/src/lplot.c to conform to your environment.
