Source Files ------------ All the source files (including this file) assume tab stops every 4 positions, not every 8 (the default). Just ":set tabstop=4" in vi, for example. Yo no habla emacs, but I'm sure its doable in emacs. What to do ---------- 0. Read this entire file. Read the "DISCLAIMER" file. 1. If you're using either SunOS 4.1.x, SVR4, or BSD/386, copy one of the files "Make.def.sun", "Make.def.svr4", or "Make.def.44" into the file "Make.defines". This file ("Make.defines") is included by all the Makefiles in the individual directories. Edit "Make.defines" as appropriate for your system. Note that *YOU MUST MODIFY* "Make.defines" with the pathname of the "libmisc.a" library, any special compiler flags, etc. If you aren't using one of these three systems, start with one of these three "Make.def.*" files and edit is as appropriate. I am interested in receiving any new versions of this file for additional Unix systems, as long as I can include them in future releases of this tar distribution. 2. If you're using either SunOS 4.1.x, SVR4, or BSD/386, go into one of the directories "lib.sun", "lib.svr4", or "lib.44" and type "make" or "gmake". (Be sure to read the rest of this file first.) This makes the library "libmisc.a" that almost every other program requires. This is where the error functions from Appendix B.2 reside, for example. Note that 90% of the files in these three lib directories are just hard links to each other, as the source file is identical between the three systems. If you aren't using one of these three systems, pick the directory that is closest to your system, and modify as required ... The files with a link count of 1 (i.e., those that differ between the three different systems) will probably require the most work to port to other systems. Note also that the file "systype.sh" is used by the Makefile in these lib directories to try and determine which system we're on. You almost certainly need to modify this shell script also. 3. The file "Sourcefiles" lists which source file corresponds to each Program in the book. Go into the desired directory and make whatever program you want. There is not a master Makefile that make's everything. 4. Each Makefile may contain entries for programs other than those that are distributed in this source release. These are probably for small test programs that I wrote while writing the book. Since these programs aren't in the book, and since it would take too much time to go through and figure out what each one does and document it adequately, they are not in this release. 5. Please let me know of any generic problems you encounter. I may be able to answer questions if you're having problems, but questions of the form "what does it take to compile X under FOOix" I probably can't answer, since I don't have access (and time) to try all these programs under every Unix system in existence. Using make ---------- Each directory with source code has a Makefile in it. Each Makefile includes "../Make.defines". Unfortunately on all three systems the make program is a little different: - Under SunOS I use "make", although GNU make also seems to work. - Under SVR4 I use "make". I've never gotten GNU make to compile correctly under SVR4. Fortunately the vanilla SVR4 make is OK. - Under BSD/386 I use GNU make. The standard BSD make is quite different and would require that the include line at the beginning of every Makefile be different. (Guy Harris posted patches to the BSD make that let it handle "normal" include lines, to one of the Usenet newsgroups in May 1992.) POSIX.1 Compatibility --------------------- Be aware that *none* of the systems used (SVR4, 386BSD, SunOS 4.1.2) is POSIX.1-1990 compatible--they all conform to the earlier 1***8 POSIX.1 spec. This means that you will get some compiler warnings for some of the files. The main difference between the two is that the 1990 POSIX.1 standard introduced the ssize_t return value for read and write. The SVR4 function prototypes in still say "int write(...)". *YOU WILL ALMOST CERTAINLY* get a compiler error on the "ourhdr.h" file the first time you try and compile anything, unless your system supports the ssize_t primitive system data type that appeared with the 1990 POSIX.1 standard. I've just added the typdef of ssize_t to the appropriate headers on my systems. Without root privilege you need another solution. The easiest solution might be to typedef ssize_t in "ourhdr.h" to be an int. C Compilers ----------- The only ANSI C compilers that I've compiled these programs under are GNU C (Versions 1.39 and 1.40) under SunOS and BSD/386, and the SVR4 Standard C Development Environment 5.0. I have not tried Sun's ANSI C compiler (acc) on the Sparc.
