later implementations were developed for [various platforms](https://gunkies.org/wiki/Chaosnet#Protocol_implementations).\n\n* The software creates connections over TCP/IP and Chaosnet (optionally using the [cbridge](https://github.com/bictorv/chaosnet-bridge) software).\n\n## Tested platforms\n\n* Tested operating systems: Oracle Solaris, OpenIndiana illumos, Linux/musl, Linux/glibc, IBM AIX, IBM OS/400 (PASE), Haiku, FreeBSD, OpenBSD, NetBSD, DragonFly BSD, Cygwin, and Apple macOS.\n\n## Tested compilers\n\n* Tested compilers: PCC, GCC, Clang, Xcode, IBM XL C, IBM Open XL C, Oracle Studio C, NVIDIA HPC SDK C, Portland Group C, and DMD ImportC.\n\n## Building the `supdup` client\n\n### Generic UNIX\n\n* Building on generic UNIX-like systems (**Linux**, **\\*BSD**, **macOS**, **Haiku**, etc.):\n  * Install prerequisite packages:\n    * Required: `make` (GNU), `ncurses` (libraries and headers),\n    * Recommended: `pkg-config`\n  * Build: `gmake` (or sometimes just `make`)\n[]()\n\n[]()\n* The usual environment variables (*e.g.* `CC`, `CFLAGS`, `LDFLAGS`, etc.) are respected, for example:\n  * `env CC=\"gcc\" CFLAGS=\"-Wall\" LDFLAGS=\"-L/usr/local\" gmake`\n\n### IBM AIX\n\n* Building on IBM AIX 7:\n  * Install prerequisite packages:\n    * `dnf install make ncurses-devel pkg-config`\n  * Build with IBM XL C V16:\n    * `env CC=\"xlc\" CFLAGS=\"-q64\" LDFLAGS=\"-q64\" gmake`\n  * Build with IBM Open XL C V17:\n    * `env CC=\"ibm-clang\" CFLAGS=\"-m64\" LDFLAGS=\"-m64\" gmake`\n  * Build with GNU GCC:\n    * `env CC=\"gcc\" CFLAGS=\"-maix64\" LDFLAGS=\"-maix64 -Wl,-b64\" gmake`\n  * Build with Clang:\n    * `env CC=\"clang\" CFLAGS=\"-m64\" LDFLAGS=\"-m64\" gmake`\n\n### IBM i (OS/400)\n\n* Building on PASE for IBM i (OS/400):\n  * Install prerequisite packages:\n    * `yum install gcc10 make-gnu ncurses-devel pkg-config`\n  * Build with GNU GCC:\n    * `env CC=\"gcc-10\" CFLAGS=\"-maix64\" LDFLAGS=\"-maix64 -Wl,-b64\" gmake`\n\n### DMD ImportC\n\n* Building with DMD ImportC:\n  * `dmd -betterC -c -of=supdup.o chaos.c charmap.c supdup.c tcp.c $(pkg-config --cflags-only-I ncurses)`\n  * `cc -o supdup supdup.o $(pkg-config --libs ncurses)`\n\n## Building the `supdup` server\n\n* An *experimental* server, `supdupd`, is included.\n* The server component is *antiquated*, *incomplete*, and *will not* build on all platforms.\n[]()\n\n[]()\n* To build the server on generic UNIX-like systems:\n  * Install prerequisite packages: `make` (GNU)\n  * Build: `gmake` (or sometimes just `make`)\n\n## Bug Reporting\n\n* To report a problem with `supdup`, use GitHub Issues:\n  * https://github.com/PDP-10/supdup/issues/new/choose\n\n## External links\n\n### SUPDUP\n\n* [RFC 734: SUPDUP Protocol](https://www.rfc-editor.org/rfc/rfc734.txt)\n* [RFC 736: TELNET SUPDUP Option](https://www.rfc-editor.org/rfc/rfc736.txt)\n* [RFC 746: The SUPDUP Graphics Extension](https://www.rfc-editor.org/rfc/rfc746.txt)\n* [RFC 747: Recent Extensions to the SUPDUP Protocol](https://www.rfc-editor.org/rfc/rfc747.txt)\n* [RFC 749: TELNET SUPDUP-OUTPUT Option](https://www.rfc-editor.org/rfc/rfc749.txt)\n* [AI Memo 643: A Local Front End for Remote Editing](http://www.bitsavers.org/pdf/mit/ai/aim/AIM-643.pdf)\n* [AI Memo 644: The SUPDUP Protocol](http://www.bitsavers.org/pdf/mit/ai/aim/AIM-644.pdf)\n* [PuTTY: SUPDUP Backend](https://git.tartarus.org/?p=simon/putty.git;a=blob;f=otherbackends/supdup.c;h=6f574c9fb9c34b1307b67326038aa713c2b1d07a;hb=HEAD)\n\n### Chaosnet\n\n* [AI Memo 628: Chaosnet](http://bitsavers.org/pdf/mit/ai/AIM-628_chaosnet.pdf)\n* [Chaosnet Bridge](https://github.com/bictorv/chaosnet-bridge)\n* [Chaosnet Wiki](https://chaosnet.net/)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fpdp-10%2Fsupdup","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fpdp-10%2Fsupdup","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fpdp-10%2Fsupdup/lists"}
