1. Please do NOT send me email with your "make" output, asking me what to do to get the source code working on your system. You would not believe the volume of email that I get like this, and I just don't have the time to even respond to these any more. My suggestion is to get someone locally to help (at work or at school) or to ask on some vendor-specific Usenet newsgroup.

   My publisher graciously allows all the code to be made available (to save you from having to type it in), but the code is provided "as is" with no support implied.

2. The code in the book uses features that are not widespread during 1998 (e.g., Posix IPC, a working pthreads library, Posix realtime signals, etc.). The only Unix systems that I found that supported everything that I wanted to cover in the book were Solaris 2.6 and Digital Unix 4.0B (excluding doors, which I know are Solaris-only, and Posix read-write locks, which only AIX supports). If you are bringing up the source code on some other system expect to find features described in the book that your system does not support.

   I have brought up pieces of the code (mainly the library and a few test programs) on BSD/OS 3.1, RedHat Linux 5.1, and AIX 4.3.1, but I do not have the time and resources to try and port the code to all other possible Unix variants (and all the various Linux variants with different kernels and libraries). I think the code is quite portable but it will require some effort to port the code to other Unix systems.

Execute the following from the src/ directory:

./configure    # try to figure out all implementation differences

cd lib         # build the basic library that all programs need
make           # use "gmake" everywhere on BSD/OS systems

cd ../pipe     # build and test a simple program
make pipeconf
./pipeconf /tmp

If all that works, you're all set to start compiling individual programs.

Notice that all the source code assumes tabs every 4 columns, not 8.
