45446 2004-03-22 15:51 0000 Singular has segmentation faults (probably when opening .so files) 2004-03-26 04:33:48 0000 1 1 1 Unclassified Gentoo Linux Applications unspecified x86 Linux RESOLVED FIXED P2 normal --- 1 glowwormy@web.de sci@gentoo.org glowwormy@web.de 2004-03-22 15:51:34 0000 When running singular (2.0.4-r1 and 2.0.5) I get Segmentation fault while doing normal work. For example when typing the example in http://www.singular.uni-kl.de/Manual/2-0-4/sing_10.htm#SEC16 it crashes. Reproducible: Always Steps to Reproduce: As described above Expected Results: In my opinion its another path issue. I checked the files and wrote a patch for singular-2.0.5 which should also work with 2.0.4. Also, building singular twice is not such a good idea (the standard target is install, so doing make in source_compile isnt such a good idea). The einstalls in source_install should be sufficent. I removed also some links to /var/tmp/portage from the source by this patches.

I count quite a few. Didn't manage to segfault singular the way you described. But your patch looks very reasonable. glowwormy@web.de 2004-03-23 00:52:08 0000 There's exactly one make (make CFLAGS="${CFLAGS}" CXXFLAGS="${CXXFLAGS}" || die "make failed", line 52) in src_compile. The rest are einstalls... glowwormy@web.de 2004-03-23 00:55:12 0000 By the way, did you add these ${CFLAGS}, ${CXXFLAGS}? do they have any effect? For the Segfaults: I don't know exactly when they occur, but I more or less started using Singular yesterday, and it crashed a few times. So I changed to the static, precompiled version and checked the sources later. I will try today with the new compiled Singular 2.0.5 again and see what happens glowwormy@web.de 2004-03-23 01:02:46 0000 Oh yes, and when your already at it: There a a few filenames/pathnames in feResource.cc which I didn't find, mostly related to the documentation (SINGULAR_INFO_FILE (singular.hlp), SINGULAR_IDX_FILE (singular.idx), the html docu ...). When you've got time, would you mind to check this out? phosphan@gentoo.org 2004-03-23 01:30:54 0000 I suggest you count again :-) - each einstall is a "make (tons of options) install" - there are a few more "make"s run when "doc" is in USE The *FLAGS are used for some compiler runs, not all. About the pathnames, please tell me a few commands to check if they work or not - I really have no clue how to use singular, just committed the ebuild, for the case you remember bug #26115 glowwormy@web.de 2004-03-23 01:42:26 0000 makes in __SOURCE_COMPILE__!!!! glowwormy@web.de 2004-03-23 01:46:06 0000 The easiest way to check out if the helpfiles are installed, simply start singular and type "help reduce;". Right now you will get the output: // ** Could not get IdxFile. // ** Either set environment variable SINGULAR_IDX_FILE to IdxFile, // ** or make sure that IdxFile is at /usr/doc/singular.idx ? cannot open `help.cnf` // ** Displaying help in browser 'dummy'. // ** Use 'system("--browser", <browser>);' to change browser, // ** where <browser> can be: "dummy", "emacs". ? No functioning help browser available. ? error occurred in STDIN line 1: `help reduce;` while you should get something like this: > help reduce; // ** Displaying help in browser 'xinfo'. // ** Use 'system("--browser", <browser>);' to change browser, // ** where <browser> can be: "xinfo", "info", "builtin", "dummy", "emacs". running `xterm -e info -f /home/wolfs/projects/Singular/Singular/2-0-5/info/singular.hlp --node='reduce' &` phosphan@gentoo.org 2004-03-23 01:55:25 0000 I referred to your comment #2 where you said that you "think now just the remove of the make in src_install from the ebuild is missing", and I asked of which one. So please stop screaming and thanks for comment #9 :-) glowwormy@web.de 2004-03-23 02:03:25 0000 sorry, typing and thinking don't coincide always... I meant src_compile phosphan@gentoo.org 2004-03-23 07:02:00 0000 Just added -r2 which actually gives me some reasonable output when I try "help reduce;" - could you please check what I broke this time? :-) glowwormy@web.de 2004-03-23 16:31:05 0000 O.K., lets try it with {"xterm", 'X', feResBinary,"XTERM", "%d/X11R6/bin/xterm", ""}, instead of {"xterm", 'X', feResBinary,"XTERM", "%b/X11R6/bin/xterm", ""}, (its in singular-2.0.5-r2-gentoo.diff line 101) phosphan@gentoo.org 2004-03-23 23:30:34 0000 Ok, should be enough for now. Please re-open this bug if you find something else. Thanks alot. glowwormy@web.de 2004-03-24 04:50:41 0000 in singular-2.0.5-r3.ebuild you have to replace epatch $FILESDIR/${P}-r2-gentoo.diff with epatch $FILESDIR/${P}-r3-gentoo.diff ^^^^ phosphan@gentoo.org 2004-03-24 06:03:13 0000 Ouch. This is the "this should definitely not happen" category of errors. Thanks. glowwormy@web.de 2004-03-25 08:48:21 0000 Created an attachment (id=28004) A few changes to the ebuild (mainly for the online help) glowwormy@web.de 2004-03-25 08:50:40 0000 Finally i checked to more things out: The hmtl weren't installed because they were created to late and have the extension .htm. And the missing file help.cnf was in the LIB directory. I also added the file COPYING in the LIB-dir to the installed files, because it includes the copyright of the Libraries. That should do it for now. phosphan@gentoo.org 2004-03-26 04:33:48 0000 Thank you very much again. -r4 will be there soon.
