Merc Release 2.2 Wednesday 24 November 1993 Kahn Hatchet === Platforms --- MERC 2.2 We have "lost" platforms due to the addition of MOBPrograms. I had no time to check the various platforms with the files 'mob_prog.c' and 'mob_command.c'. They should not give compile time errors just warnings. These platforms have been directly ported Dec 5000 Ultrix Intel 486 Linux --- Merc 2.0 We have ported Merc directly to these platforms: Apollo ??? Domain/OS Dec 5000 Ultrix Dec 5900 Ultrix Intel 386 MsDos Sequent 386 Dynix Sun Sun-3 SunOS 4.1.2 Sun Sun-4 SunOS 4.1.2 Users have contributed ports to the following platforms, and we have folded their changes into the base code. See 'contrib.txt' for acknowledgments. Apple 68030 Macintosh Dec uVax Ultrix HP 9000 Hp/UX Intel 386 386 BSD Intel 486 Linux IBM RS/6000 Aix Mips R4000 Risc/OS 5.XX NeXT 68030 Mach We are simply unable to test Merc on every platform. Typically a user tries a new platform, gets a file full of warnings, and mails us the warnings. We fix the base code; on the next release we ask that users mail us the new warnings (usually we never hear from the user again). === Requirements The hardware requirements are essentially: two megabytes of memory; five megabytes of disk space; any 32-bit processor; 50 kilobits per second network bandwidth. Processor speed is not important. The software requirements are essentially: a C compiler (Ansi C preferred, but Merc can be made to work with a K&R compiler via 'mktrad'); a Unix or Unix-like operating system; BSD-compatible TCP/IP networking. For machines which don't have Ansi C compilers, we supply the 'mktrad' script to convert Merc source into traditional C. See 'trad.txt' for details. Merc uses 32-bit integers and is casual about the distinction between 'int' and 'long'. (It is possible to clean up the code to run with 16-bit integers, but the demand is nonexistent, and we don't have any 16-bit C compilers with which to test.) If you are running on a personal computer, make sure your C compiler is giving you 32-bit integers and not running in 16-bit mode. Area files, player files, the note file, and the bugs/ideas/typo files are all in Ascii format, so that they may be freely moved from one machine type to another. === MsDos Single-User Version Merc runs in single-user mode (console only) on MsDos and Macintosh computers. The MsDos version is built with DJ Delorie's 'djgpp' port of the Gnu C Compiler and requires a 386 with 2 megabytes of memory (djgpp has demand-paged virtual memory). You can ftp 'djgpp' from grape.ecs.clarkson.edu. The commands to build and run Merc on MsDos are: gcc -O -Wall -c *.c gcc -O -o merc *.o go32 merc === Macintosh Single-User Version The Macintosh changes were contributed by Oleg Etiffin. It is built with Think-C 5.0.4 and requires 4 megabytes of system memory. You have to define the symbol 'macintosh' (if not already defined). === Performance All this measured on a Sun 4 with SunOS 4.1.2. Boot time: 4.3 CPU seconds. Memory: 2.1 megabytes SZ size. CPU usage: 20 CPU seconds per hour + 1-2 CPU seconds per player. Disk space: 2.6 megabytes plus 8K per player file. IP packets: about 10 per second with 20 people logged in.
