linking issue

[kelvinc@xxxxxxxxxxxxxxx (Kelvin Chan)]

Hi guys,

I'm new to pjsip and run into a weird linking issue.

I checkout the 1.5.5 and latest from svn, build them using "./configure 
&& make dep && make". the whole build goes smoothly. I can even run the 
sample apps.

However, gcc complains "undefined reference to `pj_init'" during linking 
my "hello world". I then copied playsine.c from sample apps and change 
my TARGET to playsine.c. It gives me the same error.

Both 1.5.5 and svn comes out the same. Here's some command outputs as 
well as the source.

Looks like my Makefile is not right. Any suggestions?

Cheers,

Kelvin Chan
