the pjsua runs in openwrt, we use USB SoundCard.
When we answer a call, allways choopy, both the capture and the playback are not work well!
Tips:We have use auddemo tested my soundcard, recoreding/playing are good, and the capture id is 8, playback id is 1.
thank you~~

I am working with OpenWrt and a very small amount of space.
Trying to extract the first line from a file. The line needs to go into a variable and be removed from the file. I can use head to put it into a variable but can't use tail because as far as I understand I would have to do tail file > newFile and I do not have room for that second file.
Does some one know if a better technic?

I cross compiled Valgrind to openwrt x86 platform. It doesn't detect any leaks when running on target. On Ubuntu, it works fine.
My test program is simple
main()
{
char *p = malloc(10000);
*(p-1) = 1;
}

How can I upload a file on an OpenWRT router to a place using FTPES?
I googled curl, because it's small enough to install:
opkg update
opkg install curl
and can handle FTPES connections:
http://curl.haxx.se/docs/comparison-table.html
Ok. But heres the problem: i just can't guess out, how could i upload a file.
Can someone point me to a working, good howto?

I would like to get an idea or reference to compile only subset on the openwrt project.
i am aware of the menuconfig utility but this is not enough for my goal.
i would like to compile only the tool-chain (binutils + gcc + glibc) for a specific target (ar71xx) and also the kernel.
now, after looking in the makefiles etc, i have noticed that most of the work in actually patching the toolchain and the kernel and then compile it. is there any option to stop build process after the patching so i can have only the source code patched and i can write my own make file to compile it?

I have forgotten my luci password, but can get in via ssh. How do I reset the luci password from the console? I see that in /etc/config/luci there is this:
config extern 'flash_keep'
...
option passwd '/etc/passwd'
...
So is it done with the regular passwd command?

I'm attempting to install Gnu Radio on OpenWRT "Attittude Adjustment" (latest trunk sources). I've cross compiled GR and everything seems to have compiled and linked just fine. However, importing the module in Python results in the following:
root@OpenWrt:/usr/lib/python2.7/dist-packages/gnuradio/gr# python
Python 2.7.3 (default, Jul 21 2012, 17:36:54)

Type "help", "copyright", "credits" or "license" for more information.

The target system runs on an Intel Atom. Finally, the last piece of useful information I can think of is that PYTHONPATH is set to /usr/lib/python2.7/dist-packages. I'm at a loss as to what the problem is. I hope the wonderful stack overflow community may help find a solution. Thank you in advance for any pointers!

I have an existing solution written in Java which I would love to run on OpenWrt routers. Will OpenWrt even run Java without installing a lot of dependencies? Anyone ever tried this?

I recently ported luci to openwrt router. I was just exploring the thing. I disabled the DHCP server on LAN and enabled as dhcp client. I saved and applied the configuration to the router. Now after restart I am not able to connect the router webpage.
Can anyone please let me know how to enable the dhcp server again or can anyone let me know how to reset this openwrt router to default settings?
I tried in the serial port console. but I can't see any IP address for any interfaces. Before It was 192.168.1.1.
Please suggest...

I am confused about build_dir and staging_dir in openwrt buildroot.
What are they used for?
There are feeds in openwrt. I would imagine to build an image. You will select the packages you want in menuconfig and use make to build it.
The packages are fetched from feeds and then compiled into build_dir?
Then what is staging_dir used for?

I use OpenWRT. it's a linux distribution for embedded systems
I want to know the gcc version used to compile the linux
I made some researchs in the net but without results.
I tried to execute these commands for some existing binary in the linux OpenWRT (like wget)
strings -a <default binary> | grep "GCC"
strings -a <default binary> | grep "gcc"
But I did not get any result
even the
strings -a /lib/libgcc_s.so.1 | grep "gcc"
strings -a /lib/libuClibc-0.9.30.1.so | grep "gcc"
does not give any result
Are there a way to know used gcc to build the whole linux (For both user space and kernel space)?

I'm just learning how to use message queues, and I am having a little difficulty with them. I am using two completely separate applications to do the testing -- one is the "sender", and the other is the "receiver".
When I run the sender, it sends 15 strings to the pipe, but then afterward fails with a "Resource temporarily unavailable" error. I just need to consume the messages on the receiver side, but why only 15 messages? I might be sending lots of messages, so I'd like to increase this to a much larger number, like 1000 or so.
I tried to set the message queue size to 32767, so I was expecting 31 at least, but apparently msg_qbytes is not related to the number of messages that can be buffered.
The sender code looks like this:
#include <stdio.h>
#include <stdlib.h>
#include <sys/types.h>
#include <sys/ipc.h>
#include <sys/msg.h>
#include <unistd.h>
#include <string.h>
#define MESSAGE_SIZE 1024
typedef struct msgbuf
{
long mtype;
char mtext[MESSAGE_SIZE];
};
int main(int argc, char *argv[]) {
int msgid;
int ret;
struct msqid_ds msg_settings;
long key;
struct msgbuf msg;
key = strtol(argv[1], NULL, 10);
// print the message queue ID for reading via msgrcv
printf( "Getting message queue with key = %ld\n", key);
usleep( 1000000);
msgid = msgget( (key_t)key, 0666 | IPC_CREAT);
if (msgid == -1) {
perror("msgget failed with error");
exit(EXIT_FAILURE);
}
// read in current queue settings and then set the new
// queue size.
ret = msgctl(msgid, IPC_STAT, &msg_settings);
msg_settings.msg_qbytes = 32767;
msgctl( msgid, IPC_SET, &msg_settings);
while( 1) {
msg.mtype = 1; // we'll always leave this as 1
memset( &(msg.mtext), 0, MESSAGE_SIZE);
sprintf( msg.mtext, "hi");
printf( "Sending data: %s\n", msg.mtext);
ret = msgsnd( 1, &msg, MESSAGE_SIZE, IPC_NOWAIT);
usleep( 500000);
if( ret == -1) {
perror( "msgsnd failed\n");
}
printf( "leaving...\n");
return EXIT_SUCCESS;
}
The receiver code looks like this:
#include <stdio.h>
#include <stdlib.h>
#include <sys/types.h>
#include <sys/ipc.h>
#include <sys/msg.h>
#include <unistd.h>
#include <string.h>
#include <errno.h>
#define MESSAGE_SIZE 1024
typedef struct msgbuf
{
long mtype;
char mtext[MESSAGE_SIZE];
};
int main(int argc, char *argv[]) {
long int msgtyp = 1;
int ret;
size_t msgsz;
struct msgbuf mymsg;
int msgid;
msgid = strtol(argv[1], NULL, 10);
printf( "Reading message queue with ID = %d\n", msgid);
usleep( 1000000);
while( 1) {
msgsz = (size_t)MESSAGE_SIZE;
ret = msgrcv( msgid, &mymsg, msgsz, msgtyp, IPC_NOWAIT);
if( ret == ENOMSG) {
usleep( 100000);
continue;
}
if( ret == -1) {
perror( "msgrcv failed");
} else {
printf( "Read data: %s", mymsg.mtext);
}
usleep( 100000);
}
return EXIT_SUCCESS;
}

I cross-compiled a firmware with openwrt, and a file is strange named libbfd.h and I compiling failed, I have ever seen it. In libbfd.h line 83:
79 #define BFD_HOST_64BIT_LONG @BFD_HOST_64BIT_LONG@
80 #define BFD_HOST_64BIT_LONG_LONG @BFD_HOST_64BIT_LONG_LONG@
81 #if @BFD_HOST_64_BIT_DEFINED@
82 #define BFD_HOST_64_BIT @BFD_HOST_64_BIT@
83 #define BFD_HOST_U_64_BIT @BFD_HOST_U_64_BIT@
84 typedef BFD_HOST_64_BIT bfd_int64_t;
85 typedef BFD_HOST_U_64_BIT bfd_uint64_t;
86 #endif
here BFD_HOST_U_64_BIT is defined as @BFD_HOST_64_BIT@, what's mean with "@", I tested in a test file, can't compiling. Could anybody help me? Thx!

I wanna change SSID wifi network name dynamically in OpenWRT via script which grab information from internet.
Because the information grabbed from internet may contains multiple-bytes characters, so it's can be easily truncated to invalid UTF-8 bytes sequence, so I want to use awk (busybox) to fix it. However, when I try to use bitwise function and on a String and integer, the result always return 0.
awk 'BEGIN{v="a"; print and(v,0xC0)}'
How to treat character in String as integer in awk like we can do in C/C++? char p[]="abc"; printf ("%d",*(p+1) & 0xC0);

I have created a shell with necessary functions such as
start()
stop()
restart()
But my file is not getting started at boot time.
I have used update-rc.d command in "ubuntu" to add this file to the list of autostart applications. And it was successfully started at boot time.
But in "openwrt" I have seen an enable function. Anyone aware of how to use this enable function or is there any similar command like update-rc.d in "openwrt"
I had some reference here : http://wiki.openwrt.org/doc/techref/initscripts
