Error: building a simple PjSIP program under ubuntu
I am trying to compile a simple PjSIP program under ubuntu. I am getting an error like
/usr/bin/ld: cannot find -lpjsua-i686-pc-linux-gnu
What does it mean?
Here is the output: -

EDIT:
I just noticed the PjSIP error occurs

When I tried to find -Werror in files with files present in /home/mypc/pjproject-1.4.5/pjnath/build
, $(PJDIR)/build.mak
and $(PJDIR)/build/common.mak
, it is not present there, does anyone know where it might be?

It seems that pj * is unable to create the required libraries - for a simple fix, try looking for the line in /home/mypc/pjproject-1.4.5/build.mak
where -Werror
added to $(APP_CFLAGS)
and remove it ( -Werror
rather than the whole line if other flags are added :).
Alternatively, apply the fix suggested by gcc on line 230 in src/pjnath/stun_session.c
.
edit
Just read what you didn't find -Werror
. Could you please insert line 230 of stun_session.c or makefiles somewhere?
The original string would be preferred.
