Hi Last weekend I've done a port of PDCurses for ECOS. The whole curses library built for for ARM-7 is
~/PDCurses-3.4/ecos$ arm-eabi-size -t libpdcurses.a text data bss dec hex filename 1052 0 0 1052 41c addch.o (ex libpdcurses.a) [snip] 42437 176 6731 49344 c0c0 (TOTALS) The PDCurses <http://pdcurses.sourceforge.net> sources are the very portable. I found what it's code is very compact and very qualitative. Compiling with -Wall produces no warnings. No need to mess up with the PDCurses core to port it for new OS. When I started the port, I found and again re-read Peter's Seebach article: Porting a screen-management utility to eCos on IBM developerWorks http://www.ibm.com/developerworks/power/library/pa-tams3/ Read the last sentence of the Peter's article, please. If I wrote about the PDCurses + eCos, I would resume that like Peter said, Executable size is unbeatable; the whole application is _140_KB, including kernel, drivers, curses, etc. And yet another important thing: I did no dance with the PDCurses sources like Peter did with the OpenBSD curses. I would not believe in the said the above if I could not run a `size' for the got executables just now (built for RAM startup, stripped) ~/PDCurses-3.4/ecos$ arm-eabi-size firework newdemo ptest rain testcurs worm xmas text data bss dec hex filename 62612 1376 24864 88852 15b14 firework 67852 1456 24856 94164 16fd4 newdemo 66648 1368 23752 91768 16678 ptest 62772 1356 24796 88924 15b5c rain 96956 1460 24748 123164 1e11c testcurs 67348 1396 25404 94148 16fc4 worm 69852 1348 21852 93052 16b7c xmas Those are real working demos built for my target (BTW, `testcurs' is the 1K lines written in curses). They all work very smoothly, 3 colour worms creep, aa-xmas card greets me, it fireworks, it rains, and `testcurs' and other demos learn me :-) Many thanks to William McBrine for the PDCurses! And what's about a fly in the ointment? malloc, calloc, free and curses event loop. If anyone will want to try the port, I attached it. To build the port, download the latest PDCurses 3.4 sources from SF. Build the demos for x11 or sdl1 to taste a honey. Unpack `pdcecos.tar.gz' under PDCurses-3.4 tree then and follow the instructions in the ecos/README* files. Notes: 1) The port was tested on Linux Ubuntu 8.04 with Olimex LPC-E2294 board using `minicom' communication program. 2) I never wrote in curses, but I used `whiptail' a while ago, so, I won't help you on curses. 3) the port is two-days `weekend mechanics', so, it may be not ideal, it was my first look on PDCurses. 4) I do not know much about this remark from PDCurses's README ---->8 The core package is in the public domain, but small portions of PDCurses are subject to copyright under various licenses. Each directory contains a README file, with a section titled "Distribution Status" which describes the status of the files in that directory. ---->8 So, I can not answer on Q: Is it possible to enter PDCurses in eCos CVS tree? In any case I think that PDCurses can be the very useful library to build the excellent TUIs under eCos. That's it. Regards, Sergei
