This is not really a FreeBSD problem ... in fact, it's happening on a Solaris 10 machine. But because the TCP stack and its userland interface came from BSD, I am hoping some kind soul might have an insight into what's going on ... The machine in question does DNS lookups fine via dig or nslookup. I believe these connect directly to the DNS server(s) specified in /etc/resolv.conf. However, any program that uses gethostbyname() - like ping - fails and says it cannot resolve the name. I'm looking for hints here on why or how gethostbyname() and/or the network stack could get clobbered so as to not be able to talk to the DNS servers which I know are reachable via dig and nslookup. dig and nslookup use THEIR OWN resolver routines, =not= the 'standard library' routines. Something that fouls the library routines will not affect dig and nslookup. Given this is Solaris, check /etc/nis.switch (may not be the exactly correct name, but close -- I haven't used Solaris in a decade). check both the file content, and permissions. You may have to run truss on ping to see what it's getting wrong. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

Replacement for KGET from KDE3
I'm looking for a replacement for kget from KDE3 which I use with Konqueror on easynews.com. As the site has download accounting and I have a slow dsl line I have hundreds of files queued-up - often for months. Ideally what I after is something similar - Browser integration - The ability to queue and reorder downloads with only one or a few downloading at once - doesn't lose the queue on crashes. - authentication, and ideally SSL, support I thought I'd be able to get something working with Firefox+flashgot, but aria dumps core, flashgot doesn't seem to do anything with steadflow, urlgfe isn't recognised by flashgot and wxdfast doesn't seen to be able to authenticate to easynews (any doesn't seem to have any queue support anyway). The last time I tried kget from KDE4 they'd removed the queue management and made it like Opera and Firefox's built-in download manager. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
FreeBSD 8.2 with pre-built KDE 3.5 package from FreeBSD 7.1 DVD
Hi everybody, My issue is the following: As far as I know, FreeBSD has completely dropped support for KDE 3.5. Whether it's the ports, or the pkg_add precompiled binaries. Am I right in assuming this? I am currently running a live version of FreeBSD 8.2 with KDE 4.8. The thing here is, that KDE 4 is simply too heavy for my system. For example: it is impossible for me to have two open shells at the same time. Once I exit a given shell, I can't open another one due to a lack of resources, even after having turned off all the extra stuff - plasma desktop, nepomuk... As a consequence, I can see myself do two possible things, to have a system running with KDE 3.5 once again: 1. Go back to an older release of FreeBSD and install KDE 3.5 from the precompiled binaries that are on the DVD donwload version. Judging by the release announcements, this should be 7.1. http://www.freebsd.org/releases/7.1R/announce.html This is something that I don't really feel like doing. 2. To be honest, I am quite happy with 8.2 and I would like to keep it for some time to come. In other words, is there a way to keep 8.2 and still have KDE 3.5 along with it? For example has anyone ever tried to install a 7.1 pre-built package (KDE 3.5 in this case) on an 8.2 system? Is that be possible? Any other solutions?

Some decisions from upstream are a PITA. I'm from Linux, it's more up-to-date than FreeBSD. On Linux I switched from KDE 3 to GNOME 2, when KDE 4 was introduced and from GNOME 2 to Xfce, when GNOME 3 was introduced. There are forks of GNOME 2, but I guess there's no fork of KDE 3. Some users claim that it should be possible to set up KDE 4, that it become equal to KDE 3. I doubt that. Another issue are hard dependencies, such as the dependency to the buggy pulseaudio.

Hi, I'm the author of svn-export. I haven't really touched the code since I wrote it in 2009 and back then I tended to write most things in noobish Perl. Although it should not be difficult to replace threading with forking (and I agree that Perl threading is generally to be avoided), I think I would rather just rewrite it cleanly in Python. Among other things it will simplify argument parsing and subprocess invocation via standard library functions. This would be in Python 3 but I could try to restrict it to be compatible with Python 2 if necessary. Would that be better than patching/porting the current Perl version? If so then I will put it on my todo list, but I am unlikely to have any time in the coming weeks to work on it.

Once I exit a given shell, I can't open another one due to a lack of resources, even after having turned off all the extra stuff - plasma desktop, nepomuk... Excuse me... you're joking, right? I assume you have a plentycore processor with Gigs of RAM, and already two shells show a problem? That sounds totally wrong. When you play a music file and move the window, do you get skipping audio, too? Just scary... As a consequence, I can see myself do two possible things, to have a system running with KDE 3.5 once again: 1. Go back to an older release of FreeBSD and install KDE 3.5 from the precompiled binaries that are on the DVD donwload version. Judging by the release announcements, this should be 7.1. Yes, this will work. But note that you are running an OS that has been gone out of support, so you probably won't be able to install newer software using ports or packages. However, you can use the system as is, and even use ports as long as the distfiles are still kept available online. 2. To be honest, I am quite happy with 8.2 and I would like to keep it for some time to come. In other words, is there a way to keep 8.2 and still have KDE 3.5 along with it? For example has anyone ever tried to install a 7.1 pre-built package (KDE 3.5 in this case) on an 8.2 system? Is that be possible? That should be possible if you install the required compat7x port on the system. Keep an eye on dependencies and make sure you won't be shooting your feet. A good start would be to install the KDE stuff on a clean system (right after compat7x) so there won't be much confusion. -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ... ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

Although it should not be difficult to replace threading with forking (and I agree that Perl threading is generally to be avoided), I think I would rather just rewrite it cleanly in Python. Among other things it will simplify argument parsing and subprocess invocation via standard library functions. This would be in Python 3 but I could try to restrict it to be compatible with Python 2 if necessary. Would that be better than patching/porting the current Perl version? If so then I will put it on my todo list, but I am unlikely to have any time in the coming weeks to work on it. A working version in any language would be great. A better version in Python would be nice, too, but it's the working part that's important. Incidentally, when looking at the code now I noticed that there were some SVN options missing. I have added those in today's release. Regards, Xyne p.s. I have not subscribed to this list, so please keep me in CC if you would like me to reply (in case this isn't done automatically).

Dependencies after port tree update
Hi :) I had to do a portsnap fetch update to compile icedtea-web and run into a dependency hell. Most apps can't be launched anymore. When I deinstall, recompile the new versions and install them, I have tons of dependencies for each app. Is there a way to automatically recompile all broken apps and dependencies? If needed I could restore from a dump backup and continue with repeating the portsnap fetch update or what ever else, but I would prefer to fix the install.

Yes, using a port management tool such as portmaster should be able to resolve all those problems automatically, usually by explicitely requesting the compile everything (update all ports) action. See the EXAMPLES section of man portmaster for how to do this. -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ... ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

As explained, gcc issues a valid (!) warning because there was a type mismatch: You tried to printf() a (long) value with %ld, but a (int) value (requiring %d) was supplied to the function. It's not gcc's job to advice the programmer on what he should do. You _intendedly_ write something, and the compiler treats your words as truth. If you formulate something wrong, the compiler will complain, and that's okay. Warnings are a good means to deal with such minor errors. Mayhe the question is beyond this list. Allow me to repeat, just to be sure I haven't missed an important point: gcc47 -O2 -pipe -I../../include -std=gnu99 -fstack-protector -Wsystem-headers -Werror -Wall -Wno-format-y2k -Wno-uninitialized -Wno-pointer-sign -c data-collection.c data-collection.c: In function 'main': data-collection.c:214:4: error: format '%ld' expects argument of type 'long int', but argument 3 has type 'time_t' [-Werror=format] data-collection.c:234:4: error: format '%ld' expects argument of type 'long int', but argument 3 has type 'time_t' [-Werror=format] cc1: all warnings being treated as errors *** [data-collection.o] Error code 1 The compiler option -Werror=format informs you: format '%ld' expects argument of type 'long int', but argument 3 has type 'time_t' That matches the source: gettimeofday(spi_stop, tz); / * line 211 */ printf(Loop %d, SPI %ld %ld\n, loop, spi_stop.tv_sec, spi_stop.tv_usec); gettimeofday(disk_stop, tz);/* line 231 */ printf(Loop %d, Disk %ld %ld\n, loop, disk_stop.tv_sec, disk_stop.tv_usec); disk_stop.tv_sec and disk_stop.tv_usec are (timt_t). You've properly included the include files for time_t variables. There are recursive typedefs as follows: /usr/src/sys/sys/types.h (line 253): typedef __time_t time_t; /usr/src/sys/i386/include/_types.h (line 97): typedef __int32_t __time_t; /usr/src/sys/i386/include/_types.h (line 55): typedef int __int32_t; In the end, you have this type chain: int - __int32_t -- __time_t - time_t Or in the reverse order: time_t - __time_t - __int32_t - int So _at least here_ (!), (time_t) is equivalent to (int). Repeating: In your format string, you request a position for a (long) argument, but gcc encounters an (int) value instead and validly issues the proper warning. So to speak, you're doing something wrong here. You can avoid the problem by typecasting the (time_t) values to (long): printf(Loop %d, SPI %ld %ld\n, loop, (long)spi_stop.tv_sec, (long)spi_stop.tv_usec); Or you can change the format parameter to %d: printf(Loop %d, SPI %d %d\n, loop, spi_stop.tv_sec, spi_stop.tv_usec); However, the most clean solution is to combine both methods: Cast the (time_t) values to (int) _and_ use the %d placeholder: printf(Loop %d, SPI %d %d\n, loop, (int)spi_stop.tv_sec, (int)spi_stop.tv_usec); The reason is simple: You should not blindly _rely_ on the assumtion that (time_t) which you know is some integer type is _exactly_ (int) -- it doesn't neccessarily have to be. Similarly, you shouldn't assume that it's (long) either. I hope this verbose explanation has been easy to understand. -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ... ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
