I'm trying to write a very small, very simple project using PJSIP. But I'm already stuck on the first step, incorporating PJSIP in my project. I'm trying to build and compile on a Ubuntu 14.04 system using an arm-linux-gnueabihf-gcc cross compiler. For the coding itself I'm using Eclipse CDT, but the crosscompiling part is working in a normal order.

I downloaded de pjproject-2.3 folder to my system, configured it with this command:

   ./configure --host=arm-linux-gnueabihf CFLAGS='--sysroot=/home/david/rpi/rootfs' LDFLAGS='--sysroot=/home/david/rpi/rootfs' 

The /home/david/rpi/rootfs folder is where I copied the rootsystem of my Pi. I then ran 'make dep' and 'make'. I copied all the static libraries *.a to my Eclipse project folder and added the libraries to the linker (-l).

But when I want to build I get the following error:

I googled some and tried to add -fPIC to the CFLAG in the ./configure step above, recopied the libraries, but without result. Does anyone know what this message is saying me, and better yet, knows a solution?

This problem has been resolved. I was using a library that also linked to the srtp library, this evidently conflicted. So I am now not using the library that causes the problem.
