When statically linked Abort trap: 6 (core dumped)
Hi all This is FreeBSD 9.1 on i386. My program works well without any issue when all libraries are dynamically linked. But when some libraries are statically link and run it develops: Abort trap: 6 (core dumped) How I compile and link: cc myprog.c -Wall -O \ -L. -ls1 -ls2 \ -lz -lm -lmd -lpthread \ -o myprog libs1.a and libs2.a are static libs. Any idea why? Many thanks in advance.

Bind99 stopped resolving for external queries
Hi all I'm running a FreeBSD 9.0-RELEASE based server. It used to work fine. But suddenly about 2 days ago stopped resolving DNS for external queries. From my laptop if I ping the server: ping www.mydoamin.com ping: cannot resolve www.mydoamin.com: Host name lookup failure But if I log in to the server and do the same ping, it works fine. As a fix, I have upgraded the Bind99 to the latest bind99-base-9.9.2, but it did not fix the issue. I don't see anything changed in my DNS server setup. Appreciate very much if any help could be extended in this regard to understand what went wrong in the server. Many thanks in advance.

Hi! Mind to share code snippet caused the problem? Hi Thanks for the reply. I have mentioned in my original post that neithe r I nor SDL use the flockfile () in the source. There was a _reason_ the prior poster asked about seeing your code. The information you provided is not adequate/sufficient for anyone to have any chance of helping you. Informationn that -is- necessary was therefore requested. What you don't use is irrelevant to solving the problem. To be any help one must figure out what you _did_ do -- which =indirectly= calls flockfile(). Your code calls something in 'libc' that calls flockfile(). You don't know what that something in your code is. Other eyes _might_ recognize it, -if- they saw what you were doing. Here is how to find out what does that calling, yourself. 1) recompile all the components of 'myprog' with the '-g' compiler option. 2) start 'script', so that you have a complete log of the debugger session. 3) load the debugger with 'myprog' as the program to be debugged. 4) set a breakpoinnt in the 'flockfile' function 5) 'run' the program 6) when it stops at flockfile() entry. use 'where' to see a stack trace. 7) 'display' each of the arguments to flockfile(). 9) go 'up' to the calling code. 9) repeat steps 7 and 8 util you reach 'your' code. 10) now 'continue' the program. If it immediately segfaults, this was the offending call. Otherwise, the program will stop aggain at another flockfile() invocation. repeat from step 7 -until- you get the segfault. If, from that debugger session, you still don't see anything wrong, post the log of the debugger session. There is a *remote* possibility that the program will run properly under the debugger, while it crashes when run directly. This has been known to happen when a program _uses_ a variable before initializing it. *IF* that happens, you will have to modify 'myprog' to add diagnostic output before and after each identified point (above) in your code that indirectly invokes flockfile() to find which is failing. In _that_ event, you =will= have to post the 'relevant' source-code from 'myprog', with the failing statement identified. Hopefully I have not offended anyone with my reply :) Very sorry if I did. My this FreeBSD 9.0 box is seems very messy. I have another issue that getaddrinfo(3) doesn't accept localhost. After installing FreeBSD 9.0, I installed KDE, then realised that the existing Intel display driver does not support my Intel Sandy Bridge based GPU. So I had to patch the kernel to support KMS based latest Intel driver, upgraded to Xorg to 7.5.2, etc. etc. Whole process was done multiple times as I was new to this complex upgrade. I presume, I should erase off the hard disk and reinstall everything cleanly and then retry my programs on FreeBSD 9.0. If the problem still persists, I'll surely do a detailed debug. Pls note, whole thing works well on FreeBSD 8.1. As this is time consuming and as per existing commitments, I only try this at least in another two weeks time. I will sure let the list know the outcome.

localhost not recognised in getaddrinfo(3) in FreeBSD 9.0-STABLE
Hi all
Following code fragment works in FreeBSD 8.1-RELEASE, but not in FreeBSD
9.0-STABLE:
error = getaddrinfo(localhost, port, hints, res0);
if (error)
{
fprintf(stderr,getaddrinfo failed - %s\n, gai_strerror(error));
exit(1);
}
It complains: getaddrinfo failed - hostname nor servname provided, or not known
Any idea why?

Grub1 doesn't seem to support FreeBSD 9. It cannot recognise the file system type. Any help in this regard is very much appreciated. It isn't very difficult and there are at least two ways to do it. Grub1 actually does support ffs and ufs2 file systems, but the linux distributions don't seem to include the drivers. If you can get the source, that should have all of them. I think that I just got the grub package from the FreeBSD file system and copied the additional drivers directly into my linux grub directory, but I am not sure now. The other way is to use the 'chainloader' command. You just specify the disk and partition (slice) with the root command, and then add the commands 'chainloader +1' and 'boot'. The chainloader command just means to boot whatever is at the first sector of the previously specified disk and slice. I think the first sector of a ufs2 file system just jumps to the loader. The menu items from mine are just: title FreeBSD /boot/loader root (hd1,2,a) kernel /boot/loader boot title FreeBSD chainloader root (hd1,2) chainloader +1 boot In my case, those specifies that they use the third slice on the second disk. The first menu item requires that you already have the 'ufs2_stage1_5' file in your grub directory. Hi Carl Thank you very much for the reply. Your second method (ie. chainloader) worked, but the grub still say file system type is unknown. The ufs2_stage1_5 is available in /boot/grub/. Since now I can have a working dual boot with Linux, I conclude this is solved.

Is KDE 4.4.5 on FreeBSD 8.1 this bad?
Hi all I have installed KDE 4.4.5 from ports (ie. with full compilation) on FreeBSD 8.1 on i386. Once HAL and DBUS is enabled in /etc/rc.conf, behaviour of KDE is surprisingly poor: 1. None of the desktop icons works to launch programs. Eg. Click or double click on Firefox icon does not launch Firefox. I have to right click on the desktop and click on Run Command and type firefox to run. 2. Once type firefox on the Run Command it doesn't appear until I shake the mouse! Once press enter, it doesn't run firefox till I shake the mouse again. The firefox comes in stages and every stage I have to shake the mouse to continue. Do others experience the same with KDE 4.4.5? Do I have to do some configurations to overcome this issue?

Works for me. errno 2 is ENOENT (No such file or
directory). I would inspect
if your request path points to the right location.
% ./rl /dev/stderr
/dev/stderr = fd/2
% cat rl.c
#include sys/types.h
#include sys/param.h
#include unistd.h
#include stdio.h
#include stdlib.h
#include string.h
#include err.h
int main(int argc, char **argv)
{
char path[MAXPATHLEN],
buf[MAXPATHLEN+1];
ssize_t res;
if( argc != 2 )
exit(67);
(void)strlcpy(path, argv[1],
sizeof(path));
res = readlink(path, buf,
sizeof(buf));
if( res 0 )
err(EXIT_FAILURE, readlink());
buf[MAXPATHLEN] = '\0';
printf(%s = %s\n, path,
buf);
return (0);
}
Thanks everybody for valuable replies. In fact, I also used readlink(2) but fed
the symlink path directly from dirent, which was partial, readlink(2) requires
full path.

How to modify the default unmount time of automounter (amd)?

amd_enable=YES
cat /etc/amd.conf

Best regards Unga Unga, This is the first time I've read from you that you were using the recommended shell. Given you're running the recommended shell and you're still having problems sporadically (users = ok, root = not), I'd start the invasive discovery why it's not working. First is system-wide: is your kernel version and userland in sync? Such as RELENG_7 userland with RELENG_7 kernel? Running non-synchronized kernel and userland (aka world) is not supported* and will cause problems. Back to the individualized problem -- if you backup your root's dotfiles, and then remove or rename them, does the problem remain? What if you set root's home directory to one of your user's home directory as a test to see if it's the dotfiles? These would be my next steps to diagnose what might be the problem. Good luck. * - Only supported is when you're upgrading and have a newer kernel just long enough to install world. Dear Tim I suspect this is a build error. Therefore, let me rebuild and see whether the problem go away. I'm going to do a careful rebuild more towards the end of the week. I'll let the list and you know the result. If the problem still persists, I really like to know what causes it.

Exactly the same in posix standard /bin/sh or in
bash. bash(1) should
be capable of running any compliant /bin/sh script
directly. The converse
is not generally true, so for maximum portability write
according to sh(1)
and avoid bash-isms.
If you're asking about converting csh to bourne shell, then
that's a whole
other kettle of fish. The echo commands above just
happen to be the same in
either language, but that's one of the few points of
confluence between the
two. Typically you'ld have to know both languages and
laboriously translate
between them.
Here is what happens in bash shell:
$ echo ${X} ${Z}
bash: ${Z}: ambiguous redirect

That's not how you set a variable. Do it like this:

You're mixing up variable initialisation with output to

Aha. This looks remarkably like an address in the runtime
stack. It
usually happens when you have a function that returns the
address of a
'local' variable, instead of a newly allocated heap
area, i.e.:
char *
function(void)
{
char buffer[100];
return buf;
}
This problem happens very early stage of my program. Its the very first free()
develops a problem.
I checked again, up to the this problematic free(), functions return newly
allocated strings properly:
char *f( )
{
char *newstr = NULL;
:
newstr = (char *) malloc(p - sp + 1);
if (newstr == NULL)
return NULL;
:
return newstr;
}
Can a yet not executed wrong free() elsewhere cause a problem of this nature?

This was indeed the case, worst yet, I was trying to free a part of the buffer
(as per your example above) by mistake which was not allocated by malloc.
Thank you all who helped me.

Segmentation fault when free
Hi all
I'm running FreeBSD 7 on i386. I have a C program compiled with gcc 4.2.1
20070719.
Logically my program is:
char *a;
char *b;
char *c;
while (cond)
{
a = f1(); /* malloc() and send a string */
b = f2(); /* malloc() and send a string */
c = (char *) malloc(strlen(a) + strlen(b) + 1);
c[0] = '\0';
strcat(c, a);
strcat(c, b);
free(a);
free(b);
}
When it executes free(b), my program exits with Segmentation fault: 11. The
free(a) executes well.
The problem is with free(b). Even swap free(b) first and free(a) next, it still
crashes at free(b).
If I comment out free() lines, further down the program, first few characters
of one string get dropped when executes a completely unrelated line.
How could I bit more narrow down the problem?
Many thanks in advance.
Kind regards
Unga

char *c;
char *abd = Hi, im a string 1\0;
char *bbd = Hey, im a string 2\0;
char *f1(void){

ab = malloc(strlen (abd));
memcpy(ab, abd, strlen(abd));
printf(f1(): %s\n, ab);
return ab;

Hi thank you very much for your reply and the test case.
That is, in a trivial case like this, free() works well. Hopefully free() works
well in all cases too.
But my main program is 1900 lines, f1() and f2() are in a 2200 lines second
file. The f1() and f2() calls some functions from a 500 lines third file. The
main program call another function, f3(), from 2nd file, pass pointers to two
functions f4(), f5() of main program. The while loop iterate more than one
million times. Its quite a complex situation.
There must be an error somewhere else. I noted free() causes lot of troubles.
It is easy to write complex programs if you just let to leak memory. But in my
case, since the program iterate millions of times, if I let to leak, I'm sure
it will run out of RAM.
So the question is, if you were to encounter this issue, how would you approach
it and find the culprit?
I'm using pretty basic tools to write complex programs. I use Kate to write
programs, Makefiles to compile, use GCC, and use ddd in case of a trouble.

How to split a C string by a string?
Hi all I'm writing an C application on FreeBSD 7+. I need to split a string by another string (ie. the delimiter is xxx) similar to strtok split a string by a single char.

You can use strstr() to look for the xxx
delimited and split that that
point:
% cat -n foo.c
1 #include stdio.h
2 #include string.h
3
4 int
5 main(void)
6 {
7 char text[] = Hello string
world;
8 char delim[] = string ;
9 size_t dlen = sizeof(delim) /
sizeof(delim[0]) - 1;
10 char *p;
11
12 p = strstr(text, delim);
13 if (p == NULL)
14 return 0; /* No
match */
15
16 printf(First part =
\%.*s\\n, p - text, text);
17 printf(Second part =
\%s\\n, p + dlen);
18 return 0;
19 }
% cc -std=iso9899:1990 -O2 -Wall foo.c
% ./a.out
First part = Hello
Second part = world
%
Thank you very much for the reply. That is, there is no existing split
function. So I got to write to my own :)

[EMAIL PROTECTED] Unga: I think your problem is that each element of the pipeline runs in a separate process, so has no access to the variables from other processes. You could try something like: echo Name:Surname:10 | ( IFS=: ; read name surname age ; echo $surname) Thanks for the reply. Your statement prints the Surname but the variable $surname disappear after that and not available for further processing. I'm referring to two sources for this: 1. Learning the bash shell, 2nd Edition. O'Reilly publishers Where on page 170, under read section The basic syntax is: read var1 var2... This statement takes a line from the standard input and breaks it down into words delimited by any of the characters in the value of the environment variable IFS. The words are assigned to variables var1, var2, etc. 2. http://www.unix.com/shell-programming-scripting/29202-perl-like-split-function-bash.html It looks like it works for others but here on FreeBSD 7.0, bash 3.2.33(0)-release, I find it difficult to get this syntax to work. Also, probably a typo - but you're assignment of string in the first line should omit the $ sign. Yes, sure is a typo.
