Re: Playing music using pike and SDL.
by Martin Nilsson (lvl 60) ＠ Pike (-) developers forum 22 Sep '05

Were you not able to get any C code to play through SDL either? Does your SDL library have a mixer compiled in it (I think it is optional)?

Playing music using pike and SDL.
by 墳墓 15 Sep '05

15 Sep '05

I'm trying to develop a game engine using pike. But there is a big problem that I can't play any sound file using pike and SDL. I write a simple test script trying to play a .wav sound file, but it exit and nothing happened when I run this program. Here is my code, where should I check? int main () { SDL.init( SDL.INIT_AUDIO ); SDL.open_audio ( 22050 , SDL.AUDIO_S16 , 2 , 4096 ); SDL.Music music = SDL.Music ( "test.wav" ); music->pause(); music->play ( 0 ); SDL.quit(); return 0; }

problems with constant Classname = (program)"Classname.pike"
by Tobias Josefowitz 14 Sep '05

14 Sep '05

I've discovered a problem with Pike 7.6.24 (and 7.6.34) when using constant Classname = (program)"Classname.pike" statements: 12:41 ~/fetch KingOfPrussia) pike fetch.pike Incorrect number of arguments. .. expected behaviour. but: 12:41 ~/fetch KingOfPrussia) cd hui 12:42 ~/fetch/hui KingOfPrussia) pike ../fetch.pike /home/tobij/fetch/ImgJob.pike:1:Error evaluating constant. Cast "FetchJob.pike" to program failed. /usr/lib/pike/master.pike:1002: master()->cast_to_program("FetchJob.pike",0,0) /home/tobij/fetch/ImgJob: object(/home/tobij/fetch/ImgJob.pike)->__INIT() /usr/lib/pike/master.pike:349: master()->compile_string("static constant FetchJob = (program)\"FetchJob.pike\";\n\ninherit FetchJob;\n\nstatic Regexp.PCRE fname = Regexp.PCRE(\"([^/]*)$\");\n\nstatic void "+[190],"/home/tobij/fetch/ImgJo b.pike",0,/home/tobij/fetch/ImgJob,0,0) /usr/lib/pike/master.pike:819: master()->low_findprog("/home/tobij/fetch/ImgJob",".pike",0,0) /usr/lib/pike/master.pike:928: master()->findprog("/home/tobij/fetch/ImgJob",".pike",0,0) /usr/lib/pike/master.pike:976: master()->low_cast_to_program("ImgJob","/home/tobij/fetch/fetch.pike",0,0) /usr/lib/pike/master.pike:998: master()->cast_to_program("ImgJob.pike","/home/tobij/fetch/fetch.pike",0) /home/tobij/fetch/fetch.pike:0: object(/home/tobij/fetch/fetch.pike)->FetchJob() /usr/lib/pike/master.pike:349: master()->compile_string("#!/usr/bin/pike\n\n#ifndef NT\n# define NT\t4\n#endif\n\n#define unless(x) if(!(x))\n\nstatic constant Manager = (program)\"Manager.pike\";\nstatic cons"+[1034],"/home/tobij/fetch/ fetch.pike",0,/home/tobij/fetch/fetch,0,0) /usr/lib/pike/master.pike:819: master()->low_findprog("/home/tobij/fetch/fetch",".pike",0,0) /usr/lib/pike/master.pike:928: master()->findprog("/home/tobij/fetch/fetch",".pike",0,0) /usr/lib/pike/master.pike:964: master()->low_cast_to_program("/home/tobij/fetch/fetch","/usr/lib/pike/master.pike",0,0) /usr/lib/pike/master.pike:998: master()->cast_to_program("/home/tobij/fetch/fetch.pike","/usr/lib/pike/master.pike",0) /home/tobij/fetch/ImgJob.pike:1:Error in constant definition. /home/tobij/fetch/fetch.pike:11:Error evaluating constant. /home/tobij/fetch/fetch.pike:11:Error in constant definition.

The problem might be that ImgJob.pike gets compiled by low_findprog(), and the compiler seems to not supply the 'current_file' argument to it's cast_to_program("FetchJob.pike", ...) call... Should this behaviour of Pike considered to be a bug, or are my casts illegitimate? PS: Martin Baehr told me that the problem does not occur with Pike-7.6.13.

Pike Wiki
by Bill Welliver 09 Sep '05

09 Sep '05

There have been on and off calls for a wiki-like application for people to share information about Pike development and related topics. Not much ever came of it, so I decided to do something about it. I wrote a simple wiki application yesterday and have made it available for anyone to contribute to. Anonymous editing is restricted, in order to minimize possibilities of spam, but the authentication is shared with the pike module repository, so if you've already got a modules.gotpike.org account, you're set to edit. I've started things off with some of my own personal information. Take a moment and share your notes and thoughts (there's a page with notes and guidelines for contributions, please have a look before you post): http://www.gotpike.org/PikeWiki As always, comments and suggestions are welcome. I'll give you all a week or so to bang on it before I share this with the general lists. Bill

Re: FreeBSD, threads and autoconf.

> Now IDA can do whatever they like... but if they do not, this is one > more time a proof that pike is a language that is dying... IDA provides free hosting. It does not provide free development; that is ambition based, and your words of encouragement are better aimed at the heroes who spend time making Pike better, of their own free will.

FreeBSD, threads and autoconf.
by Xavier Beaudouin 06 Sep '05

06 Sep '05

Hi there. After thinking *why* coredump generated was getting both libraries libpthreads and libc_r... I have tested pikefarm with forcing library...using --with-thread-library flag. Now it is working right on freebsd.home.oav.net so we can easyly guess the autoconf is b0rken with freebsd > 5.0 about thread support. Since CVS access is not working, can someone patch autoconf to *avoid* -lc_r and -lpthread and/or -lthr on FreeBSD. Defaut that should be used : - FreeBSD < 5.0 : -lc_r (this is the _only_ thread library that exist) - FreeBSD >= 5.0 < 5.3 : -lc_r (but -lkse, -lthr and -lpthread exists. note that -lpthread is -lc_r on these version) - FreeBSD >= 5.4 : -lpthread (but -lc_r, -lthr still exists). Now this will fix all freebsd pikefarm from stock... and help all FreeBSD developpers to *really* find the problems. And this case was not "fix your OS" case, but fix the bloooooody autoconf brain damage. /Xavier
