hello,
I have little problem :)
I have embeded device on ARM CPU 255 architecture 5TE and i cross compile
pjsip library as:
export CFLAGS="-pipe -I/usr/toolchain-arm-26/usr/include -I/usr/toolchain-
arm-26/include --sysroot=/usr/toolchain-arm-26/ -isysroot /usr/toolchain-
arm-26-mtune=xscale -mabi=aapcs-linux -msoft-float"
./configure --prefix=/opt/emtest/arm_install --host=arm-linux --disable-oss
make dep && make
In my toolchain is used uclibc version 0.9.29 non standart libc.
For my testing purpose i using pjsua test application. but when i starting
aplication :
./pjsua --id sip:pc1@192.168.32.17 --registrar sip:192.168.32.123 --realm
asterisk --username pc1 --password heslo --app-log-level 6 --log-level 6
i get error:
15:41:46.080 sip_reg.c Invalid Contact:
"(null)sip:pc1@192.168.32.17:5060(null)(null)"
here is full output:

On 386 it works fine. i try last trunk version 2985. and
pjproject-1.4.5.tar.bz2 from download page too and i get same error.
Can me somebody help?
...thank you
Hi,
I have the same error for MIPS architecture ; I posted exactly same
details of yours few days ago.
Hope any experienced guru can help us. I have tried to trace back where
the issue may be but I have no knowledge of the internals of PJSIP,
structures, etc.. and I don't know where to start looking for...
Regards
Antonio

Hello,
I think your problem comes from ulibc in function vsprintf or sprintf. I
had this problem in newlib 2 years ago.
This function seems not correctly manages format : %.*s.
I think
printf("%.*s\n",len,(char *)NULL); displays (null)
snprintf(ptr, 40, "%.*s", len, (char *)NULL) give ptr = "(null)".

Hello,
I think your problem comes from ulibc in function vsprintf or sprintf. I
had this problem in newlib 2 years ago.
This function seems not correctly manages format : %.*s.
I think
printf("%.*s\n",len,(char *)NULL); displays (null)
snprintf(ptr, 40, "%.*s", len, (char *)NULL) give ptr = "(null)".

I would agree with Samuel, the problem is with *printf() functions in
newlib/uclibc, and you shoul fix that instead. We use "%.*s" format
pretty much everywhere, there are lots of them throughout the library,
and chances are some of them will give NULL in the pointer argument.
Or worse, an arbitrary value that may crash your little board.

Yes i have to agree with you. My solution isn't good because
other place give "(null)" strings and pjsua not work correctly...
But when precision is 0 and string is NULL pointer what should be function
printf return? "(null)" string or "" string...I thing "(null)" is for debug
purpose...and this behavior isn't defined..
Or is this behavior some norm ?...because if not,
and it's only feature glibc then it is "hack"...don't you think?
I would agree with Samuel, the problem is with *printf() functions in
newlib/uclibc, and you shoul fix that instead. We use "%.*s" format
pretty much everywhere, there are lots of them throughout the library,

Yes i have to agree with you. My solution isn't good because
other place give "(null)" strings and pjsua not work correctly...
But when precision is 0 and string is NULL pointer what should be function
printf return? "(null)" string or "" string...I thing "(null)" is for debug
purpose...and this behavior isn't defined..
Nothing should be printed when the precision is zero.
Or is this behavior some norm ?...because if not,
and it's only feature glibc then it is "hack"...don't you think?
Or just find "(null)" in your libc library and replace it with empty
string. I think I did that at one point.
