Can you post some more information? A copy & paste of (1) the command
you run that generates the error, (2) the last, say, 50 lines of
output (more if you think it'll help) will help greatly!  Also, what
architecture are you building on? Are you cross-compiling?

All I want my script to do is call the specified URL in* else* part( when
they run the script ) or when I press 'm' call the URL I enter. This just
the part of code. It registers to example.com( since it's test after few
mins it says timeout )

The only line on my shell prompt is:
output/rach-i686-pc-mingw32/rach.o:rach.c(.text+0x4cf): Undefined reference
to 'pjsua_invite'.

All I did when I downloaded the source from pjsip.org, is installed GNU
compiler( Mingw, msys ) and in shell prompt gave the below command:
cd C:/pjproject-1.3
./configure
./make dep && make clean && make

To run the pjsua:
cd pjproject-1.3/pjsip-apps/bin
./pjsua-i686-pc-mingw32
and that ran the pjsua_app.

Since I need a script to suit my requirement I went to write my own.

It would be great if you'll help me out.

Thanks!

What's the command-line when you compile? Are you compiling with -Wall

Grepping through my include/ and lib/ directories for pjproject-1.3, I
can't find a function in any header file or object in any of the
libraries called pjsua_invite - if you compiled without -Werror, the
compiler probably only spat out a warning of an implicit declaration
and left the error for the linker to find. Try recompiling with
-Werror or just search for warnings to this effect.

I've not used past versions of this library - could this be a function
you're using from an old API?

If successful, it places the executable in

I'm not aware about the command to compile with -Wall and -Werror?

How I give the command after cd C:/pjproject-1.3? And if the warning or

Thanks!

Remember to resave your source file (or run "touch path/to/file.c" or
whatever) to ensure make thinks it should rebuild it.

But like I said, I can't see pjsua_invite() defined anywhere - where
are you getting that from?

This is not an error - far from it, it's actually a good thing! When
make says "nothing to be done for 'all'", that's because the
source/object files that your target (i.e. your executable) depends on
are all older than the target itself, so it doesn't need to waste your
time by rebuilding it.

You can force make to rebuild your target by resaving your source file
or, for example, running the 'touch' program on the file.

You need to tell make all the source/object files your target depends
on, so it knows when to rebuild your executable - if you don't know
how, a quick look at a tutorial on make should tell you what you need
to know.

This is literally what it sounds like - the file doesn't end with a
new line. Find the file pjlib/include/pj/config_site_sample.h, go to
the end, add a new line.

Also, if you change the line:

CFLAGS = $(APP_CFLAGS)

to read:

CFLAGS = $(APP_CFLAGS) -Wall -Werror

you can just execute "make".

include new c script for building in samples.mak file

rach .= rach /

Doesn't make CFLAGS='-Wall -Werror' do the job.

When I saved rach.c ( pjsip-apps/src/rach) and typed the command: make
CFLAGS='-Wall -Werror' provided I added it to make file(Samples.mak)

My output was:

Why is that?

On Thu, Sep 10, 2009 at 5:24 PM, John Graham <johngavingraham@googlemail.com

Try making with just "make" instead of "make CFLAGS='-Wall -Werror'" -
all these flags do is to give you more warnings (-Wall) and to treat
warnings as errors (-Werror). They were useful in finding out your
last problem because even though the problem was highlighted at link
time, it was really a problem at compile-time, and the -Wall option
highlights this.

Note that if you're compiling pjproject-1.3 after a fresh ./configure,
you're best to do it with just "make" - pjproject's compilation
generates a few warnings, and it's frankly not worth the effort.

Also, the error you've shown doesn't really help, I'm afraid - that's
just make telling us which file an error occurred in. Try sending the
last 50 lines of the output in the future - don't worry about sending
too much output, better too much than too little!

sometimes it's kinda weird when the error or warning keeps changing every

'make' did the job.

I'm still struck with previous error "undefined reference  to 'pjsua_invite'

I replaced it with pjsip_inv_invite, pjsua_make_call, but it shows the same
instead of pjsua_invite it's either pjsip_inv_invite or pjsua_make_call.

I tried your other code(pjsua_inv.c) it shows me lots of error.

At least in my previous program do we have any  function to make call after
I enter the URL.
when I press 'm' as console key.
it says: Enter the URL to call(empty to cancel): and when I enter
sip:user@sipprovider.com sip%3Auser@sipprovider.com, it should be calling
but It does nothing.
Do I need the media to do this part(I'm not sure )

Rachel

On Thu, Sep 10, 2009 at 7:09 PM, John Graham <johngavingraham@googlemail.com

That error comes up because there is no function called 'pjsua_invite'
defined in the pjsua API - you need to go through the current API for
a function that does the job you want.

pjsua_inv.c is purely to demonstrate how the pjsua_invite function was
implemented - it probably uses deprecated/changed parts of the API.
It can be a useful starting point, but like I said you'll either need
to write your own pjsua_invite function or find a library function
that does the job already.

I don't really know the sua/sip side of the library well enough to
help you more than that, I'm afraid!
