Hi, all!
I am novice in this list, so don't beat freely :)
I confronted with a strange thing using boost.signals on SLES 9 SP3. I
suspect, that it is bug, becase on FC4 and RHEL AS 3 all fine.
Test case:
--------------------- CUT HERE ------------------
#include <boost/signal.hpp>
#include <iostream>
struct MySlot {
void operator() ()
{
std::cout << "YES!" << std::endl;
}
};
MySlot myslot;
boost::signal<void ()> mysig;
int main()
{
mysig.connect(myslot);
return 0;
}
--------------------- CUT HERE ------------------
Compile and run:
c++ test.cc -o test -lboost_signals
./test
Programm will succesfully exit.
Compile and run:
c++ test.cc -o test -lboost_signals -pthread
./test
Programm will not exit never.
Any ideas?
P.S. I can't use GCC without '-pthread' because my program used thread...
Hi,
I am using SuSE linux 10.0. To impove performace of network I/O we would like
to use poll or epoll. Is it neccesary that /dev/poll and /dev/epoll is
required. If so how do we create that devices?
Thanks in advance

"The ultimate truths of nature are so subtle
that they can be revealed only under immense silence"
I compiled one routine (m15gui.c) belonging to a big Monte Carlo package
with compiler option -g to build the symbol table just for this routine
only.
It sounds confusing. But what I did is to append the routine source file
"m15gui.c" to the GNUmakefile as follows:
SRCS := marsmain.f m1505.f m5gui.c
Then I replaced the original compiler and linker options:
CFLAGS := -O3 -xarch=v8
LDFLAGS := -fast -xarch=v8 -xlang=f77 -L/usr/openwin/lib
with the following:
CFLAGS := -g -xarch=v8
LDFLAGS := -fast -g -C -xs -xildoff -xarch=v8 -xlang=f77
-L/usr/openwin/lib
It compiled fine.
The program I wish to debug resides in /home/mauede/mars15/dev
When I launch DDD and open the program a message window pops up.
The title is: DDD No Source
The message reads as follows:
/home/mauede/mars15/dev/sysdeps/i386/elf/start.S: no such file or
directory
OK Help
I swear there is no such directory:
sysdeps/i386/elf
in my working directory:
/home/mauede/mars15/dev
Please, notice that my laptop is 64-bit and the message above sounds
like it's searching for some 32-bit feature ... ?
I'm debugging a 32-bit code.......
Are the DDD settings to be changed ? If this is the case then how shall I
change them ???
Isn't "elf" something system related ?
Thank you so much for your help,

When I joined FNAL for the first couple of weeks I just used my laptop.
We could configure both
the wire and wireless network cards to work with FNAL network thanks to
the help of SuSE mailing-list experts.
Then I got an office and a desk computer at work.
At home I got the DSL activated and thanks to a AT&T technician I could
configure both my laptop
wire and wireless cards to work with the AT&T network.
This morning I came to the lab with my laptop as my office has been
remodeled and the desktop computer is still disconnected.
As you can imagine I could not connect my laptop to FNAL network either
through the wire or the wireless card.
It is the same problem that arouse with the printers. I configured my
laptop printing system to communicate with CUPS server here at FNAL.
So I can print from my laptop when I'm at the lab. But I can no more print
at home as my local EPSON ink-jet printer configuration has been
overwritten or invalidated by the configuration I had to do for printing
at the lab.
Some time ago someone told me it's possible to have a profile for each
environment where the laptop is operated.
My understanding is that each profile uniquely identifies some environment
specific settings so that different environment configurations
can be used alternatively.
How can I create and use more profiles ? How can I relate the single
profile with a specific configuration ?
Thank you so much for your help,

Dear List,
I'm a newbie in .net and C# programming and read a lot about the mono
project and I felt now it is time for me to learn a bit of it. :)
So I have an up-to-date opensuse 10.0 and installed the MONO/CLR
packages from yast. But if I want to start monodevelop i get the
following error message:
/opt/gnome/lib/libgnomeui/gnome_segv: symbol lookup error:
/opt/gnome/lib64/libgtk-x11-2.0.so.0: undefined symbol:
g_object_compat_control
I searched the web but found no mono specific answer instead there are
only gnome related answer saying I should up/downgrade glib. The current
version of glib2 by me is 2.8.5-18 and glib is 1.2.10-606.
Did somebody get an error like this? If yes then how to solve it, if no
then where shall I start finding the solution?
Best regards
Ferenc Stelcz
p.s. Tried with the binary installer from go-mono.com but that fails too
complaining about gnome-sharp imports. Then tried with Red Carpet but
because of a server misconfiguration the download directory on the
server gives HTTP 403.
I'm seeing a fairly reproducable problem in which the same file
descriptor is being used concurrently in two threads, but
_unintentionally_.
I understand that open file descriptors are shared by all threads, but
somehow it looks like calling socket() in one thread is able to return a
filedescriptor that's already in use by another thread.
Here's an example (a little complicated, but bear with me):
this is just stderr debugging output from my app which is running 3
threads at this time. The output is in chronological order.
The thread# is in [] to the left, my comments are prefixed with >>> :
[01] using fd 16 for /tmp/ibwd.1
[01] state-transition: 2->3
[01] writing to left ( 0 bytes left): 250 Ok: queued as 29C9E4637
[01] state 3; left event LEFT_RSET: [6 bytes] RSET
[01] all done <message-id>: 2995 bytes
[01] writing to right ( 0 bytes left): RSET
[01] state-transition: 3->1
[01] state 1; right event RIGHT_354: [37 bytes] 354
[01] using fd 14 for /tmp/ibwd.1
>>> above thread#1 has opened a file and gets fd 14 for it.
[01] state-transition: 1->2
[02] crm114[25958, 9 categories] stage done, 0.509 seconds.
[02] connected to juggernautd(14) at localhost:787
>>> above thread#2 opens a tcp connection to another app, and ALSO uses
fd 14.
[01] state 2; left event LEFT_EOM: [3 bytes] .
write_string(): unable to write to 14; error 9: Bad file descriptor
>>> above thread#1 chokes when trying to write to fd 14.
Each thread is independent of the others, except during allocation of
work. Are there any special precautions I need to take when doing IO
in a multi-threaded environment?

Hi all,
i've made a NIC (Broadcom NIC) driver upgrade floppy disk containing default/smp/bigsmp .ko files.
I added update.post script to this floppy disk. This update.post aims to replace OS-embedded tg3 NIC driver (tg3.ko) with my own Broadcom NIC driver (bcm5700.ko), and without the end customer to do anything after installation.
My question is: What should be included in update.post to modify the SUSE to use my broadcom.ko for default NIC driver, instead of OS-embedded tg3.ko.
Many thanks for your looking-inside.

valgrind always complains about overlapping strcpy()s, even when the
src-address is clearly > dst-address. I know the strcpy manpage says
the operands may not overlap, but surely an overlap where src>dst is
still ok? Why is valgrind unhappy about it?
