Yes, but you will also need bits of code from libutil. If you have all
the necessary bits in a new file, i.e. util.c, then you should be able
to use:
cc -o date date.c netdate.c vary.c util.c
Extracting the minimal parts of libutil and writing the new util.c file
is an interesting and amusing exercise for a budding C programmer, but
it should be both possible and relatively ``easy''.

Re: xview problem
> and I get the same error for any other application using xview. IMHO it is a libX11 bug. The current libX11 version is compiled with USE_XCB, and the XCB implementation of XAllocID(dpy) (in the famous xcb_io.c) requires you to call the (private) _XIDHandler(dpy) function before calling it again. But our beloved XView library calls XAllocID 4 times in a row. Adding an _XIDHandler after each XAllocID in xview/server/server.c solved the problem for me. My question is where to post this bug, as it should be fixed in libX11 and not in libxview.

The free() function isn't guaranteed to release memory back to the OS; it
just makes it available to the process for another malloc(). Large
allocations that libc used mmap() to allocate memory for might actually get
returned to the OS immediately. Small allocations are placed in pages with
similar-sized ones, and all would have to be freed before the page can be
reclaimed. Even when the page does free, libc won't return it immediately
to the OS, to avoid extra overhead if your process calls a similar malloc()
again.
If I add a loop to your main() function, and add your missing
pthread_detach() call, here's the memory usage I see on each iteration:
2220
2348
2476
2604
2732
2860
2860 ... no change after here
So it reached a steady state after 5 loops.
See these links for the gory details:

It's a linker statement, while it's logical that libutil has to be built
before it can be linked against, this does in fact not have to be the same
libutil, so what this line really cares about is that libutil.so or libutil.a
is resolvable via the various linker rules.
One can in fact do:
LDFLAGS=-L/usr/local/lib
LDADD=${LIBUTIL} -lutil
This will link the static libutil from bsd.libnames.mk and then try to link
with /usr/local/lib/libutil.so, before looking elsewhere.

Re: pthread_detach doesn't release memory
I should have provided a little more detail. Even if I strip my thread function
down to nothing more than this:
void *mythread(void* param)
{
pthread_exit(NULL);
}
my application still grows by 128 bytes each time I spawn a thread with this
function. There is no explicit memory for me to deallocate, and my
understanding was that by using pthread_detach then any temporary structures
allocated by the OS would be released when the thread terminates. This doesn't
seem to be the case though, so I'm assuming I'm doing something wrong but I do
not know what.
I use the follow simple app to test this behavior:
int main()
{
getchar();
pthread_t thread;
pthread_create(&thread, NULL, mythread, NULL);
getchar();
printf("done");
getchar();
}
When I hit the first getchar, I check the application's size using ps from
another terminal window. It shows 12312k. I then allow the application to
proceed to the next getchar, and again check its size with ps. It shows 12440k.
Finally, I let it proceed to the final getchar, and again ps shows 12440k. Even
if I wait a while the size remains at 12440, and if I create additional
threads, then each one adds to the application's footprint.
What am I missing?

This indicates that libutil is a build dependency for
the date program.

That was my initial idea. The date program seems to depend
on two things: First the kernel interface which would be
something similar in Linux, and the libutil library, which
is maybe present on Linux, too.

This is because the under appreciated FreeBSD make system does a *lot* of work
for you.
- You need libutil: /usr/src/lib/libutil or (probably faster), see which
functions from libutil date uses and re-implement them.
- Resolve header issues in the above source files
- And then it's most likely easiest to use cmake or autotools on linux to
compile.

Are you malloc'ing some data in your thread and not freeing it before exiting? pthread_detach simply lets the system discard the thread when it exits instead of preserving the return code (for pthread_join to retrieve). It isn't responsible for freeing all memory allocated by the thread, and it shouldn't, since one thread may allocate memory that another thread frees later. -- Dan Nelson dnel...@allantgroup.com ___ 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"

Sure. A command like "gcc -o date date.c netdate.c vary.c" works,
provided you patch date.c to remove the dependency on libutil (logwtmp
function). This will stop date from logging to wtmp(5).

With this patch, the executable only depends on libc.
Note that I have only confirmed that it compiles _on FreeBSD_. There
might be additional differences between FreeBSD libc and the GNU libc
that is used on Linux that make further tinkering with the source necessary.

Thanks for the suggestion Tim - and everyone else who replied. Sorry for not responding earlier. I can certainly pick up a T23 reasonably cheaply, but I was thinking more of something kind of netbook sized - ie. with a 9in screen. Something that's a bit easier to lug around.

No sound backend in kde4
Hi, I recently (re)-installed kde4.1 from packages, and I now see nothing in the system settings/audio/backend, although I know that at least Jack is installed (from ports), and before I reinstalled, I had three options there. As a result, Juk does not even pretend to play files, although YouTube, Mplayer play sound fine. Please help!

Xorg manual configuration
I haven't got any response to Xorg in a jail, so I'll try and wing it... That said, I do need some help trying to figure out how to: 1. Determine exactly what Xorg is probing for (what details it needs, etc). So far I think I need memory address ranges, chipsets, etc. Found a lot of stuff in the log, but I'm not sure if its enough or all I need. 2. Then take the details and set them out in the Xorg.conf. (VideoAdaptor Section?) What I'm finding really annoying is why the manual configuration systems are completely unavailable as of now. I remember my first crack at getting X running on a 4.3 system, and having to go through screens of configurations for the monitor, card, inputs, etc. Ok, its cool now that we don't need to do this anymore, but it does kill things if you're trying this in a system which is restrictive. >From all the info I gathered so far /dev/io is used for the probing. IF the >details are entered manually, then surely this would mean it doesn't need io. >I'm still not sure what to do about /dev/mem and /dev/kmem.

No need. cron wakes up every minute and reads all known crontabs afresh, including the system one in /etc/crontab. -- Daniel Bye _ ASCII ribbon campaign ( ) - against HTML, vCards and X - proprietary attachments in e-mail / \ pgp2c62KmrrkP.pgp Description: PGP signature

Yes. > Or am I misunderstanding the word "key" here? That's how block ciphers work, nothing special here. Keys must be of the size(s) supported by the algorithm. If you read the openssl manual more closely, it says it expects the password file to be a text file, containing lines of text, and the first line will be used for encrypting. It will most likely hash the password thus retrieved into a suitable key for the cipher. signature.asc Description: OpenPGP digital signature
