Jam won't link my c++ app

Hi,

Jam is trying to link using "cc" to link my c++ .o
files which 
apparently does not include c++ routines.  Why isn't jam
using an 
appropriate linker on my system?

Thank you!

Chris

I agree it's strange.
My solution: just add the following line somewhere (I choose
Jamconfig)

LINK = g++ ;

Hope it is useful, and I'm still waiting for a better
solution.

Mildred,

Thank you, this worked for me.  Strange I do not see this
problem in the 
docs or on google.  I wonder if our systems are
misconfigured.

if I had to guess, it know where your runtime routines are
for C++

Mildred figured it out.  jam invoked cc for linking when it
should have 
invoked g++.
